Lusy makes it easier to get the fiber your body needs every day.
More than 90% of Americans do not consume enough fiber, while over 50 million experience constipation annually and 16% live with chronic constipation.
Using science-backed fiber, Lusy supports digestive regularity, constipation relief, blood sugar control, lower LDL cholesterol, appetite control, IBS management, and a healthy gut microbiome. Oh, and did we mention it tastes absolutely delicious?
Mix one serving into at least 8 oz of cold water, stir well, and drink promptly before it thickens.
For regularity and general fiber support, take it whenever you can be consistent. For fullness or blood sugar support, take it 15–20 minutes before a meal. If you’re new to fiber, start slowly and increase gradually.
Lusy is made with organic psyllium husk, citric acid, natural flavors, stevia, monk fruit, and beet juice powder for color. It’s sugar-free and contains no artificial ingredients. Lusy contains no major allergens.
Please review the product label for the complete ingredient list and other relevant allergen information.
The organic psyllium husk in Lusy forms a gel in your digestive tract that helps support regularity, healthy stool consistency, digestive health, healthy cholesterol levels, a steadier blood sugar response, and greater fullness between meals.* Results may vary and consistent daily use is important.
Lusy is designed for daily use when taken as directed on the package and with enough water. Some people may experience temporary gas or bloating when first increasing their fiber intake, so starting gradually can help.
Never swallow the powder dry. Take it at least 2 hours before or after oral medications.

“The strawberry lemonade flavor is light and refreshing. It doesn’t have that orange, artificial taste that many fiber products have.”
“I expected it to taste medicinal, but it’s surprisingly good. It's really a treat. I mix it with cold water and drink it right away before it gels up”
“Absolutely delicious!! I can't believe this doesn't have sugar. It's sweet and tasty, makes taking fiber not feel like a chore.”
“I stir it into cold water for about 20 seconds and it’s ready. No blender or shaker bottle needed.”
“Lusy mixes well as long as I stir briskly. I rarely see clumps after stirring but when I do I just crush them with the spoon or stir some more and they are gone. It's a lot easier to mix than other supplements I've tried”
“I keep a spoon and glass next to the pouch. It takes less than a minute to prepare in the morning.”
“It costs a couple cents more per serving than Metamucil, but the flavor and ingredient quality make it very much worth the difference for me.”
“I went up to 2 servings a day so the pouch lasts me about a month, which I think is a great deal considering all the benefits”
“When I calculated the cost per serving, it was a no-brainer. For me, the best part is that I actually feel like using this product every day. I have a graveyard of soon-to-expire fiber supplements at home. Lusy won't be one of them”
“After adding Lusy to my routine, my digestion has felt more regular and predictable. It works gently for me.”
“I wasn’t expecting an overnight change, but that's pretty much what I got in terms of helping me stay regular. It's also nice to know about all the other benefits of Lusy”
“This has helped me stay regular without feeling harsh or urgent. Consistency seems to make the biggest difference. It's also surprisingly good at helping me control my appetite! I take it before lunch every day.”
“I chose Lusy because it uses organic psyllium husk and doesn’t contain artificial sweeteners. The ingredient list is straightforward.”
“I’m sensitive to artificial sweeteners, so I appreciate that Lusy doesn’t use them. It tastes clean and doesn’t leave a strange aftertaste.”
“I compared several fiber supplements before buying. Lusy had the kind of simple ingredient list I was looking for.”
“I used Metamucil for years, but I never enjoyed the orange flavor or the fact that it contained artificial ingredients. Lusy tastes better and is much easier for me to drink every day.”
“I switched from Metamucil because I wanted organic psyllium husk without artificial sweeteners or colors. Lusy gives me the fiber I need with ingredients I feel better about.”
“Metamucil worked, but I often skipped it because I didn’t enjoy drinking it. Lusy tastes better to me, mixes easily, and has become a regular part of my morning routine.”

One delicious daily fiber with six clinically studied benefits.
Forms a gentle gel that softens stool, adds bulk, and helps normalize consistency for daily digestive support.
Best for: Daily regularity and digestive comfort.
Helps slow glucose absorption after meals, supporting a steadier post-meal blood sugar response.
Best for: Taking before your highest-carb meal.
Psyllium soluble fiber helps bind bile acids and supports healthy LDL cholesterol levels.
Best for: Heart health support alongside a balanced diet.
Psyllium forms a viscous gel that helps you feel fuller between meals and may reduce hunger and the desire to eat.
Best for: Taking 15–20 minutes before your largest meal.
Helps normalize stool consistency while offering a gentler fiber option for people sensitive to highly fermentable prebiotic fibers.
Best for: Sensitive digestion and irregular stool consistency.
Psyllium is partially fermented by gut bacteria, producing short-chain fatty acids that help nourish the intestinal lining and support beneficial bacterial populations.
Best for: Supporting gut health with a gentler, better-tolerated fiber.
Click each benefit to explore how it works, key evidence, and how to use Lusy to get the most of each.
1. Regularity & digestive comfortPsyllium husk is listed as a first-line intervention for chronic constipation in multiple clinical practice guidelines. The gel softens stool by drawing in water, while the insoluble fraction adds bulk and accelerates transit. Uniquely among fiber supplements, psyllium normalizes stool consistency in both directions: it relieves constipation and firms loose stool.
Key evidence: A 2022 meta-analysis published in the American Journal of Clinical Nutrition reviewed 16 clinical trials involving 1,251 adults with chronic constipation. Fiber supplementation produced a clinically meaningful response in 66% of patients vs. 41% in the placebo group. Psyllium was identified as one of the most effective fibers for this outcome.
Note: Unlike stimulant laxatives, psyllium husk (as in Lusy) does not create dependence and is appropriate for long-term daily use.

2. Blood sugar controlPsyllium husk's gel physically slows the absorption of glucose in the small intestine, blunting the post-meal blood sugar spike. This effect is relevant across the glycemic spectrum, from healthy individuals to those with type 2 diabetes.
Key evidence: A 2024 systematic review and meta-analysis of 19 randomized controlled trials found that psyllium supplementation significantly improved glycemic markers:
Benefits were most pronounced at doses of ≥10 g/day and with supplementation lasting ≥10 weeks — both thresholds met by consistent daily use of one serving of Lusy twice a day.
Note: For blood sugar management, Lusy is most effective when taken 15–20 minutes before the most carb-heavy meal of the day. This allows the gel to form before digestion begins, resulting in a lower blood sugar spike.

3. LDL cholesterol support†Psyllium's gel binds bile acids in the small intestine, preventing their reabsorption. The liver must draw LDL cholesterol from circulation to synthesize new bile acids, resulting in a dose-dependent, measurable reduction in circulating LDL.
Key evidence: A meta-analysis by Jovanovski et al. (2018), published in the American Journal of Clinical Nutrition, pooled data from 28 randomized controlled trials involving approximately 1,900 subjects. At a median dose of ~10 g/day, psyllium supplementation reduced:
The LDL-lowering effect has been shown to be additive to statin therapy in trials where statins were used concurrently.
FDA Health Claim (1998): The FDA has authorized a health claim for psyllium husk and cardiovascular disease — one of only a small number of dietary ingredients to ever receive this designation. The claim reads:
"Diets low in saturated fat and cholesterol that include 7 grams of soluble fiber per day from psyllium seed husk may reduce the risk of heart disease."
Two servings of Lusy (2 rounded teaspoons) provide exactly 7 g of soluble fiber from psyllium husk — meeting the full daily threshold specified in this claim.

4. Appetite controlPsyllium slows gastric emptying, prolonging post-meal satiety and reducing inter-meal hunger. This effect is entirely mechanical and is most pronounced when psyllium is taken before eating.
Key evidence: Two randomized, double-blind, placebo-controlled crossover trials by Brum et al. (2016) evaluated psyllium at doses of 3.4 g, 6.8 g, and 10.2 g taken before meals. Psyllium significantly reduced hunger and desire to eat while increasing feelings of fullness. The most consistent and reproducible effect was observed at the 6.8 g dose, replicated across both trials.
Note: The recommended protocol is one serving taken 15–20 minutes before the largest meal of the day. This will also allow for the highest blood sugar control benefits.

5. IBS ManagementPsyllium is one of the few fiber supplements recommended across both major subtypes of IBS — IBS-C (constipation-predominant) and IBS-D (diarrhea-predominant) — and is classified as a first-line intervention in multiple clinical guidelines for IBS management.
Key evidence: A randomized controlled trial published in the British Medical Journal (2009) found that 10 g/day of psyllium significantly reduced IBS symptom severity compared to both placebo and wheat bran. Improvement was most pronounced in IBS-C, with clinically meaningful benefit also observed in IBS-D patients.
Note: Psyllium is better tolerated in IBS patients than high-fermentability fibers such as inulin and FOS, because its limited fermentation in the colon produces less gas. This is an important distinction for someone that is often sensitive to these symptoms.

6. Gut microbiome supportWhile the primary benefits of psyllium are mechanical and metabolic, it also has a modest prebiotic effect.
A portion of psyllium reaches the colon largely intact, where it undergoes partial fermentation by gut bacteria, producing short-chain fatty acids (butyrate, acetate, propionate) that support the intestinal epithelium, reduce local inflammation, and feed beneficial bacterial populations including Bifidobacterium and Lactobacillus.
Note: The partial — rather than complete — fermentability of psyllium is also what makes it significantly better tolerated than dedicated prebiotic fibers in individuals with sensitive GI tracts.

Naturally delicious flavors make Lusy easy to drink daily, which is essential for optimal effectiveness.
Lusy absorbs water and forms a gel. This helps you feel fuller longer and may help reduce blood sugar spikes by trapping sugars*.
Lusy also traps bile acids and carries them out. To replace them, the liver uses cholesterol to make more bile acids, helping support healthy cholesterol levels†
Lusy reaches the colon mostly intact, feeds beneficial gut bacteria, and softens stool by holding water to support regularity*.
Lusy and bound waste are naturally eliminated, supporting digestive and gut health*.
Psyllium husk is the outer seed coat of the Plantago ovata plant. It is mostly fiber and is especially valuable because it forms a gel when it touches water. That gel is the main reason psyllium, and therefore Lusy, works differently from many other fiber supplements.
Many people notice improved regularity within 1–3 days of consistent psyllium use. However, your experience may depend on your diet, hydration, current fiber intake, and digestive system.
We recommend using cold water or a cold beverage. Hot liquids can make psyllium gel faster, which may create a thicker and less pleasant texture.
It depends on your goal. For appetite control and blood sugar support, take Lusy about 15–20 minutes before a meal. For regularity or general fiber intake, the most important thing is consistency, so take it at a time you can stick with daily.
Psyllium naturally thickens as it absorbs water. That gel is what makes it effective, but if you wait too long, the drink can become too thick. For the best experience, mix it well and drink it shortly after preparing it.
Yes. Always mix Lusy with enough water and never swallow dry psyllium powder. Psyllium can also slow the absorption of some medications, so it is best to take it at least 2 hours before or after prescription medication. Consult a doctor before use if you are pregnant, nursing, taking medication, have a medical condition, have difficulty swallowing, have a chronic GI condition, or experience abdominal pain, nausea, vomiting, rectal bleeding, or a sudden change in bowel habits.
Lusy was created as a more modern psyllium supplement. It tastes absolutely delicious (which is very important) and it uses premium ingredients.
For example, Lusy uses organic psyllium husk and does not rely on added maltodextrin for mixability, as does Metamucil. Lusy also uses natural flavors, monk fruit, stevia, and beet juice powder instead of artificial flavors, artificial sweeteners (aspartame), and artificial colors (Yellow 6).
Lusy and Benefiber are both fiber supplements, but they use different types of fiber, so they work differently in the body.
Lusy is made with psyllium husk, a gel-forming fiber. When mixed with water, it forms a thick gel that helps support regularity, digestive health, appetite control, healthy blood sugar response, and LDL cholesterol levels.
Benefiber is made with wheat dextrin, a non-gel-forming soluble fiber. It dissolves easily and is mainly used for gentle fiber support and gut microbiome support, but it does not form the same thick gel that gives psyllium its broader digestive and metabolic benefits.
So, the simple difference is this:
Benefiber is better if you want a tasteless fiber that dissolves easily. Lusy is better if you want a more comprehensive fiber supplement for regularity, digestive health, appetite control, blood sugar support, and LDL cholesterol support.
Psyllium capsules are convenient, but they usually contain only about 500–700 mg of psyllium each. To reach a meaningful serving of 5–7 grams, you may need 8–12 capsules. A drink mix makes it easier to take an effective amount and allows the psyllium to hydrate quickly.
*These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.
†Diets low in saturated fat and cholesterol that include 7 grams of soluble fiber per day from psyllium husk, as in Lusy, may reduce the risk of heart disease by lowering cholesterol already within normal levels. One rounded teaspoon of Lusy has 3.5 g of this soluble fiber.
