7 Best Natural Constipation Relief Remedies in 2026 (Doctor-Approved)

Bottom line up front: Over-the-counter laxatives work fast, but they often leave you bloated, crampy, and dependent on them over time. Natural remedies work with your body instead of against it. Whether you need relief right now or want to fix your gut long-term, the seven options below cover both, without the dependency risk that makes pharmaceutical laxatives a poor daily habit.

Chronic constipation affects roughly 16% of adults worldwide, rising to around 33% in people over 60. Yet the first thing most people reach for, a harsh stimulant laxative from the pharmacy, is often the worst choice for regular use. The good news is that a growing body of clinical research backs natural remedies that are both safe and genuinely effective.

This guide walks through the 7 best natural constipation relief options for 2026. For each one, we explain how it works, share the evidence behind it, flag any product quality issues worth knowing (including some concerns with Metamucil’s flavored versions), and help you match the right remedy to your situation.

Why OTC Laxatives Are a Problem Long-Term, and Why Natural Options Work Better

Before choosing a remedy, it helps to understand what conventional laxatives actually do to your body, and why relying on them long-term can create a cycle that’s hard to break.

Stimulant laxatives (Dulcolax/bisacodyl, Ex-Lax) work by chemically forcing your colon muscles to contract. This bypasses your body’s natural signaling entirely. With continuous daily use over weeks, many people find their colon becomes increasingly reliant on the chemical stimulus, a pattern sometimes called “cathartic colon” in clinical literature.

Whether laxative use itself causes this, or simply reveals an existing slow-transit problem, is still debated among researchers. Either way, this is why the American Gastroenterological Association recommends stimulant laxatives mainly for short-term or occasional use, not daily management.

Osmotic laxatives like polyethylene glycol (MiraLAX, PEG 3350) are gentler and endorsed by major GI societies. The label directs adults to use it for no more than 7 days without medical supervision, though many doctors do prescribe it long-term under supervision. Separately, the FDA opened a safety review in 2018 into reports of neuropsychiatric symptoms in children using it long-term off-label.

That review hasn’t produced a formal warning yet, so it’s best treated as an open question rather than a settled risk.

Mineral oil works as a lubricant but can block absorption of the fat-soluble vitamins A, D, E, and K with regular use, and carries an aspiration risk in elderly patients. Saline laxatives (sodium phosphate enemas) carry a real risk of electrolyte imbalance and kidney damage if overused.

The core difference is this: natural remedies (fiber, magnesium, probiotics, whole foods) address the cause of constipation, whether that’s insufficient fiber, dehydration, an out-of-balance microbiome, or slow motility. OTC laxatives mostly treat the symptom, which is why they’re better suited to occasional rescue use than daily management.

Quick Comparison: All 7 Remedies at a Glance

Click any remedy name to jump straight to its full review.

1. Psyllium Husk: The Fiber Gold Standard

Evidence level: strong. Ask a gastroenterologist which natural remedy they trust most, and the answer is almost always psyllium husk. A 2025 review in the journal Przegląd Gastroenterologiczny (DOI: 10.5114/pg.2024.141832) describes psyllium from Plantago ovata as deserving its reputation as the gold standard for regulating bowel movements.

Here’s why it works. Psyllium contains soluble and insoluble fiber in roughly a 70:30 ratio. Once it reaches your gut, it absorbs water and swells into a gel-like mass. That gel softens stool, adds bulk, and stimulates peristalsis, the wave-like muscle contractions that push everything through, without irritating the colon lining the way stimulant laxatives can.

A 2022 systematic review and meta-analysis of 16 randomized controlled trials (van der Schoot et al., American Journal of Clinical Nutrition) found that psyllium taken at more than 10 grams a day, for at least four weeks, was the most effective fiber studied for chronic constipation, improving both stool frequency and consistency. (You may see a specific “75% response rate” figure attached to this claim elsewhere online. We couldn’t verify that exact number against the primary meta-analysis, so we’ve left it out here. Treat any single response-rate percentage with caution until you can check it against the original paper.)

As a bonus, psyllium also has solid evidence for lowering LDL cholesterol and improving post-meal blood sugar, making it one of the more well-rounded daily supplements available. For a deeper comparison with other fibers, see our fiber supplements guide and our piece on the whole-foods approach to gut health.

Dosage: Start with 5–6 g (about one teaspoon of powder) in 8 oz of water, once daily. Increase gradually to 10–15 g a day over 1–2 weeks. Always drink a full glass of water with each dose. Taking psyllium without enough fluid can worsen constipation or, rarely, cause esophageal obstruction. Capsules need even more water per dose than powder.

A Note on Metamucil

Metamucil is the best-known psyllium brand and has been used in clinical studies for decades. The psyllium itself works, that’s not in question. But most of its flavored versions contain ingredients many health-conscious buyers prefer to avoid.

According to the FDA DailyMed label for Metamucil Sugar-Free Orange Powder (verify against the current label before relying on this, since formulations can change over time):

• Aspartame (in sugar-free versions). Carries a mandatory PKU warning; some users report headaches or GI discomfort with regular intake.
• FD&C Yellow No. 6 (Sunset Yellow). An artificial dye that requires a health advisory label in the EU.
• Maltodextrin. A high-glycemic filler, notable since this product is often recommended to people managing blood sugar (though the amount per dose is small).
• The unflavored, unsweetened Metamucil powder avoids all of this, containing only psyllium husk and citric acid. If you want to stick with the Metamucil brand, that’s the version to buy.

Editor’s pick, cleaner alternative: NOW Psyllium Husk Caps →. Single ingredient, no artificial colors, aspartame, or maltodextrin. Five capsules provide about 3.5 g of psyllium fiber. Good for people sensitive to additives or who dislike the texture of psyllium powder.

Best powder option: Anthony’s Organic Psyllium Husk Powder →. USDA organic, gluten-free, non-GMO, no fillers. Cheaper per serving than Metamucil in bulk, and works the same as Metamucil’s unflavored version. Good for mixing into smoothies or juice.

If you prefer Metamucil specifically: Metamucil Unflavored Powder →. Contains only psyllium husk and citric acid, none of the dyes or aspartame in the flavored versions.

Pros: strongest clinical evidence of any remedy here; safe for indefinite daily use; also helps cholesterol and blood sugar; works for both constipation and diarrhea; multiple clean, affordable options beyond Metamucil.

Cons: must be taken with plenty of water; takes 12–72 hours, so not for instant relief; can cause gas and bloating for the first 1–2 weeks; popular flavored brands carry additives worth avoiding; some people dislike the texture (capsules solve this).

2. Magnesium Citrate: The Trending Mineral

Evidence level: good. Magnesium citrate has become a popular wellness supplement, and the science genuinely supports the interest. It acts as an osmotic agent, drawing water from surrounding tissue into the intestine, which softens stool and triggers peristalsis. At higher doses, it typically produces a bowel movement within 30 minutes to 6 hours, the fastest onset on this list.

Magnesium is also an essential electrolyte involved in hundreds of bodily processes, including muscle contraction, nerve signaling, and the stress response. Some research links low magnesium status to elevated stress markers and poorer sleep, and chronic stress is known to slow gut motility. So there’s a plausible, if not fully proven, connection between magnesium and constipation beyond its direct osmotic effect.

One caveat worth flagging: most of the strongest clinical trial data on magnesium as a laxative actually comes from research on magnesium oxide, a related but chemically distinct compound used more widely in Japan and other parts of Asia, not specifically magnesium citrate. The two share the same basic mechanism, but if you’re looking for trial data on citrate itself, look for studies naming it specifically rather than assuming oxide results transfer directly.

It also matters which product you buy. The pharmacy liquid (the large bottle sold for bowel prep) delivers a big single dose meant for one-time use, like before a colonoscopy. The daily supplement form (such as Natural Calm powder) delivers around 80–320 mg per serving, a much smaller dose meant for ongoing regularity, not full bowel prep. See our guide on dehydration and constipation for more on how magnesium and hydration interact.

Dosage, daily supplement form: start with ½ tsp (about 80 mg elemental magnesium) in warm water before bed, increasing slowly to 1–2 tsp (160–320 mg) as tolerated. The adult RDA is 310–420 mg total magnesium daily from all dietary sources combined, not supplements alone.

Dosage, pharmacy liquid form: follow package instructions; this is for single-use situations only, not daily use.

Top pick for daily use: Natural Calm Magnesium Citrate Powder →. Formulated for daily supplementation rather than one-off laxative use. Sweetened with organic stevia, no aspartame or artificial colors.

Important cautions: the high-dose pharmacy liquid is not safe for daily use, it can cause diarrhea, dehydration, and electrolyte imbalance. People with kidney disease should not take any magnesium supplement without medical supervision, since impaired kidneys can’t clear excess magnesium safely. Check with a doctor first if you’re on heart medication, diuretics, or antibiotics.

Pros: fastest-acting natural option; gentle osmotic mechanism rather than chemical irritation; widely available without a prescription; may support sleep and relaxation for some people.

Cons: the high-dose pharmacy form isn’t safe for regular use; risk of diarrhea or electrolyte imbalance if overdosed; not appropriate for kidney disease without medical guidance; individual response varies.

3. Herbal Laxative Tea: Gentle Overnight Relief

Evidence level: moderate. There’s something comforting about a warm cup of tea before bed that quietly does its work while you sleep. Senna-based laxative teas have been used for centuries across traditional medicine in Africa, the Middle East, and India, and modern pharmacology has confirmed how they work.

Senna’s active compounds, called sennosides, are converted by gut bacteria into molecules that stimulate the colon to secrete fluid and contract. Sennosides remain an active FDA OTC monograph laxative ingredient today. A bowel movement typically follows 6 to 12 hours after drinking the tea, which is why the classic advice, drink before bed and expect relief by morning, holds up for most people.

Tea and pills aren’t quite the same thing. Tea is diluted in water, which adds some hydration and delivers the senna more gently. Most tea blends also include herbs like ginger, fennel, or licorice root, which can ease the cramping senna sometimes causes on its own. See our complete OTC laxatives guide for how senna compares to bisacodyl and other options.

Dosage: steep one tea bag in 8 oz of freshly boiled water for 10–15 minutes (longer steeping means a stronger effect). Drink one cup before bed, and no more than one cup a day. Don’t use it continuously for more than 7 days without medical guidance. If you find you need it more often than that, it’s worth addressing the underlying cause with daily fiber and lifestyle changes instead.

Top pick: Traditional Medicinals Smooth Move Senna Tea →. Certified organic senna leaf, with fennel seed, licorice root, bitter orange peel, and coriander added to reduce cramping. Mild, pleasant taste.

Use short-term only: despite being herbal, senna is a stimulant laxative. Using it beyond 7 days can cause electrolyte imbalances, low potassium, and, with prolonged overuse, a dependency risk similar to synthetic stimulant laxatives. It can interact with digoxin, diuretics, and blood thinners, and isn’t recommended during pregnancy without medical advice. Avoid if you have Crohn’s disease, active IBD, or a bowel obstruction.

Pros: reliable overnight relief for most people; a genuinely pleasant bedtime ritual; herbal blends reduce cramping compared to senna pills alone; affordable and widely available.

Cons: short-term use only, max 7 consecutive days; can cause cramping or urgency in some people; not safe in pregnancy or with several medications; still a stimulant laxative, so overuse carries the same dependency risk as other stimulants.

4. Prune-Based Gummies: The Modern Fruity Fix

Evidence level: good for prunes, moderate for the gummy form. Prunes have been a folk remedy for constipation for generations, and clinical research has largely backed up the folklore. A well-known 2011 randomized controlled trial (Attaluri et al., Alimentary Pharmacology & Therapeutics) found prunes actually outperformed psyllium for improving stool frequency and consistency, a notable result given how well-studied psyllium is. Read more in our article on prune juice for constipation.

Three mechanisms work together here. Prunes contain sorbitol, a sugar alcohol that draws water into the colon osmotically. They also provide soluble and insoluble fiber that adds bulk. And they contain phenolic compounds, including chlorogenic acids, that appear to gently stimulate bowel contractions, more mildly than senna or bisacodyl.

The practical problem with whole prunes is that a lot of people find them unappetizing and hard to carry around. Gummies fix that: they taste like a treat, travel well, and people actually take them consistently, which matters more than it sounds. For children specifically, see our guide to fiber gummies for kids’ constipation.

Dosage: most gummies call for 2–4 per day (check the specific product label). Results typically show within 12–24 hours. The Attaluri trial used about 100 g of whole prunes a day (roughly 10 prunes); for juice, 4–8 oz a day is a reasonable starting point. Pair with adequate water. More isn’t better here, too much sorbitol causes diarrhea and gas.

Top pick: Sunsweet Prune Gummies / Amaz!n Prune Juice →. Sunsweet’s dried plums have been used in published trials; the gummy and juice versions deliver the same sorbitol, fiber, and phenolic compounds as whole prunes, with no artificial colors. Good for adults, older children, and elderly people who find chewing whole prunes difficult.

Pros: outperformed psyllium in a head-to-head trial; three mechanisms working together; genuinely enjoyable; portable; safe for daily use, including for children and the elderly.

Cons: natural sugars and sorbitol mean diabetics should monitor intake; too much causes diarrhea and gas; the gummy form specifically is less studied than whole prunes; some products add extra sugar beyond what’s naturally in prunes.

5. Probiotics: Building Long-Term Gut Health

Evidence level: emerging, but growing. Probiotics aren’t a rescue remedy. If you need relief today, a probiotic capsule won’t help this afternoon. But if constipation is a recurring pattern, if you’re reaching for laxatives more than once or twice a month, probiotics may be the most important thing on this list, because they target a biological contributor to the problem rather than just the symptom.

Your gut microbiome plays a real role in how quickly your bowel moves. People with chronic constipation often show lower microbial diversity and reduced levels of Lactobacillus, Bifidobacterium, and Faecalibacterium prausnitzii in some studies. These bacteria produce short-chain fatty acids, especially butyrate, that fuel colon cells and help regulate muscle contractions.

Several systematic reviews have found that specific strains can modestly increase stool frequency and improve consistency over 2–4 weeks of consistent use. These improvements are real but generally modest rather than dramatic, and strain matters: many cheap supermarket probiotics use strains with little evidence for gut motility specifically.

Premium pick: Seed DS-01 Daily Synbiotic →. Combines multiple clinically studied strains with a prebiotic outer capsule and a nested delivery system meant to protect bacteria from stomach acid, a common weak point in cheaper probiotics. Includes Bifidobacterium longum and Lactobacillus strains with some evidence for gut transit. Good for chronic constipation, IBS, or recovering your microbiome after antibiotics.

Budget pick: Culturelle Digestive Daily Probiotic →. Contains 10 billion CFU of Lactobacillus rhamnosus GG, one of the most studied probiotic strains in human medicine. No refrigeration needed, widely available. A reasonable starting point if you’re new to probiotics.

Pros: addresses microbiome balance rather than just the symptom; may support overall digestive health; generally safe for long-term daily use; no laxative-type dependency.

Cons: slow onset, 2–4 weeks before you notice much; strain selection matters a lot; premium products can be pricey (around $50/month for Seed); individual response varies.

6. Aloe Vera Juice: The Internal Detox

Evidence level: moderate, with important caveats. Aloe vera has been used for constipation across traditional medicine systems for thousands of years, in ancient Egypt, Ayurveda, and traditional Chinese medicine. Modern research points to compounds called anthraquinones (particularly aloin) as the active laxative agents, stimulating peristalsis and increasing fluid secretion in the colon. A 2024 review in Chinese Herbal Medicine (PMC11589282) lists aloe among the herbs commonly used for constipation in TCM.

Here’s a distinction most product labels skip: aloe vera inner gel mostly hydrates and contains polysaccharides, while aloe latex, found just beneath the outer leaf, contains the aloin that actually gives aloe its laxative effect. “Whole leaf” products retain more anthraquinones and are more likely to help with constipation, but need careful dosing. Juice made only from inner gel may offer little beyond mild hydration. See our guide on dehydration and constipation for more on hydration’s role.

Dosage: start with 1–2 oz (30–60 ml) a day before meals. Don’t escalate the dose, high aloin intake can cause severe cramping, diarrhea, and electrolyte loss. Consistent, low-to-moderate dosing is safer than occasional high doses.

Top pick: Lily of the Desert Aloe Vera Juice (Organic) →. Organically grown in Texas. The “Inner Fillet” version is gentle enough for daily use; the “Whole Leaf” version has more active compounds. No artificial preservatives or colors.

Important safety note: in 2002, the FDA removed aloin-containing ingredients from its list of approved OTC laxative active ingredients, citing insufficient long-term safety data. Food-grade aloe juices are still widely sold as food products, but this history is a good reason to favor moderation over daily reliance. Avoid during pregnancy, and avoid entirely if you have active IBD, Crohn’s disease, bowel obstruction, or kidney disease. May interact with diuretics and antidiabetic medications.

Pros: liquid format that’s easy to take and mildly hydrating; long traditional history of use; combines a laxative effect with hydration.

Cons: potency varies a lot between products; high doses can cause severe cramping and diarrhea; not for pregnancy, kidney disease, or active IBD; less clinical evidence overall than psyllium or magnesium.

7. Chia & Flax Seeds: Whole Food Fiber Sources

Evidence level: good. If you’d rather address constipation through food than supplements, chia seeds and ground flaxseed are two of your best tools. Both provide dense fiber through slightly different mechanisms, and both fit easily into meals you already eat. See our guide on the whole-foods plant-based diet for a fuller dietary strategy.

Chia seeds provide about 10 grams of fiber per one-ounce serving, roughly a third of the recommended daily intake in a single serving. Their standout quality is water absorption: they can soak up many times their weight in liquid, forming a thick gel. That gel works somewhat like psyllium in the gut, bulking stool and encouraging movement. Soaking chia before eating maximizes the gel effect; eating it dry without enough water can temporarily worsen constipation in people who are already dehydrated.

Flaxseeds provide about 2 grams of fiber per tablespoon, plus a soluble fiber called mucilage, a slippery coating that eases stool passage. Some research suggests flaxseed works in both directions, easing constipation and diarrhea, which points to an effect on regulating motility rather than simply speeding things up. One rule matters most here: whole flaxseeds largely pass through the gut undigested. Use pre-ground flaxseed meal, or grind seeds fresh yourself.

Dosage, chia: 1–3 tablespoons a day, soaked in water or added to smoothies, oatmeal, or yogurt. Drink plenty of water alongside it.

Dosage, ground flax: 1–2 tablespoons a day, added to oatmeal, smoothies, or baking. Store it in a sealed container in the fridge after opening, ground flax can go rancid within a week or two at room temperature.

Top pick, chia: Anthony’s Organic Chia Seeds →. USDA organic, gluten-free, non-GMO. Single ingredient, no prep needed.

Top pick, flax: Bob’s Red Mill Ground Flaxseed Meal →. A widely trusted brand in North America, pre-ground, resealable bag, non-GMO verified.

Pros: whole food rather than a supplement; easy to add to meals you already eat; rich in omega-3s, protein, and antioxidants; safe for indefinite daily use; the cheapest fiber source per gram on this list.

Cons: results build gradually over days to weeks rather than hours; need adequate water to work well; can cause gas or bloating at first, so increase slowly; whole flaxseeds are largely useless, ground is essential; ground flax spoils quickly without refrigeration.

3 Lifestyle Changes That Multiply Your Results

Even the best supplement works better when these three habits are in place. Some people who adopt all three find their constipation improves substantially, or clears up entirely, without needing any supplement at all.

Hydration, the most overlooked cause. Dehydration is one of the most common direct triggers of constipation. Your colon continuously pulls water out of stool as it moves through, and not drinking enough produces hard, dry stool that’s harder to pass. Aim for at least 2 liters (about 8 glasses) a day. Warm water on an empty stomach in the morning can activate the gastrocolic reflex, triggering a morning bowel movement in some people. Coffee has a similar effect for many. See our guide on dehydration and constipation for more.

Toilet posture, the “squatty potty” effect. A standard toilet puts your body at roughly a 90-degree hip angle, which can create a slight kink in the puborectalis muscle, the sling that helps keep the rectum closed. That kink can make full emptying harder. Raising your feet 6 to 9 inches with a step stool while seated straightens this angle out. A small 2003 study in Digestive Diseases and Sciences (Sikirov) found a real biomechanical advantage to the squat position for reducing straining, though it’s worth noting this was a small study rather than a large trial.

Movement, walk your way to regularity. Physical activity stimulates gut motility through your gut’s own nervous system. A study in the Scandinavian Journal of Gastroenterology (De Schryver et al., 2005) found that a structured walking program improved stool frequency in sedentary adults with chronic constipation. Even 20 to 30 minutes of brisk daily walking appears to measurably speed up colon transit time for many people. See our guide to yoga poses for constipation relief for more movement-based options.

How to Choose the Right Remedy for You

Need relief today? Try magnesium citrate before bed, or Smooth Move senna tea. These work fastest among natural options. Warm water first thing in the morning, plus a 20-minute walk, is also worth trying before reaching for any supplement.

Recurring constipation, want daily support? Psyllium husk is the evidence-based standard. Pick a clean product, NOW Psyllium Husk Caps or Anthony’s Organic Powder, rather than a flavored, artificially sweetened Metamucil version.

Prefer not to take supplements? Add chia seeds and ground flaxseed to your daily meals. They’re whole foods, not supplements, with solid clinical evidence plus omega-3 and antioxidant benefits.

Enjoy a relaxing drink ritual? Smooth Move tea at bedtime for occasional use. Aloe vera juice (purified, moderate dose) is a reasonable daily option if you prefer liquids over pills.

Dealing with chronic gut issues or IBS? A quality probiotic (Seed or Culturelle), used consistently for 4 to 8 weeks, can help rebuild gut microbiome diversity and may reduce how often constipation recurs. It’s a slower fix, but often a more durable one.

Need something portable? Prune gummies are genuinely underrated. The clinical evidence for prunes is strong, and the gummy format is enjoyable enough that people actually stick with it.

Have a child with constipation? Start with dietary changes, more fruit, vegetables, water, and whole grains. Prune juice or gummies are a reasonable first step, but check with a pediatrician if symptoms persist. See our guide to fiber gummies for kids’ constipation.

Frequently Asked Questions

What is the fastest natural constipation relief? Magnesium citrate is generally fastest at higher doses, typically working within 30 minutes to 6 hours. Senna tea (Smooth Move) usually works overnight, in 6 to 12 hours. For many people, warm water in the morning plus a 20-minute walk can trigger a bowel movement with no supplement at all. Psyllium takes 12 to 72 hours, but is the standard for daily ongoing use.

Is psyllium husk safe for daily use? Yes, it has one of the better safety records among fiber supplements for long-term daily use. The key rule: always drink a full glass of water with every dose. Without enough fluid, psyllium can paradoxically worsen constipation or, rarely, cause an esophageal blockage.

Is Metamucil really the best psyllium product? The active ingredient, psyllium husk, works well and isn’t in question. But most flavored Metamucil versions contain artificial colors, aspartame, and maltodextrin, per the FDA DailyMed label. Alternatives like NOW Psyllium Husk Caps or Anthony’s Organic Powder contain only pure psyllium, often at a lower cost per serving. If you want to stick with Metamucil, choose the unflavored, unsweetened version.

Can I take magnesium citrate every day? In low supplemental doses, like Natural Calm powder at roughly 80–320 mg elemental magnesium, yes, it’s generally fine for daily use. The high-dose pharmacy liquid is meant for occasional, single-use bowel prep only; using it daily can cause diarrhea, dehydration, and electrolyte imbalances. People with kidney disease should check with a doctor before taking any magnesium supplement.

How long does Smooth Move tea take to work? It contains senna, which typically produces a bowel movement within 6 to 12 hours. Most people drink it before bed and get relief by morning. Don’t use it more than 7 consecutive days without medical guidance, since longer-term senna use carries a dependency risk similar to synthetic stimulant laxatives.

Are probiotics good for constipation? Yes, but they work gradually rather than providing quick relief. Certain strains, particularly Lactobacillus rhamnosus GG, Bifidobacterium longum, and Bifidobacterium lactis, have shown improvements in stool frequency and consistency over 2 to 4 weeks of consistent use in some studies. The benefit builds over time by helping rebuild gut microbiome diversity, rather than just masking symptoms. Strain selection matters, not all probiotic products are equally effective.

Are chia seeds or flaxseeds better for constipation? Both are useful, through slightly different mechanisms. Chia absorbs many times its weight in water to form a bulk-adding gel. Flaxseed contains mucilage that lubricates the intestine and may help regulate motility in both directions. Using both together gives you the benefit of each. The key rule for flax: whole seeds are largely useless, so use ground flaxseed meal and keep it refrigerated to prevent rancidity.

Is it safe to take these remedies together? For the most part, yes. Combining daily psyllium, a probiotic, chia or flax seeds, and adequate water is a reasonable, well-rounded long-term approach. But avoid combining senna tea with magnesium citrate on the same day, since both can cause significant fluid shifts, and avoid senna entirely if you take digoxin, diuretics, or blood thinners. Always check with a doctor or pharmacist before adding a new supplement if you’re on prescription medication.
