NOW Certified Organic Psyllium Husk Powder Review

Psyllium Husk Powder, Organic from NOW is listed as an Excellent Source of Fiber. The product description notes that soluble fiber from foods such as psyllium seed husks, as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease. A serving of psyllium husk powder supplies 6 grams of the 7 grams soluble fiber necessary per day to have this effect. The product color is listed as yellow, and the page notes that natural color variation may occur. The product is sold by weight, not volume. Each 12 oz. bottle contains 38 servings, with a serving size of 1 level tablespoon (9g). Per serving the page lists 30 calories, 0 g total fat, 10 mg sodium, 8 g total carbohydrate, 7 g dietary fiber including 6 g soluble fiber and 1 g insoluble fiber, 0 g protein, 1.5 mg iron, and 90 mg potassium. The label states it is not a significant source of saturated fat, trans fat, cholesterol, total sugars, added sugars, vitamin D, or calcium. The suggested usage is to vigorously mix 1 level tablespoon daily into at least 12 oz. of water or juice and consume immediately, drinking plenty of additional fluids throughout the day. Users are advised to start with smaller amounts and gradually increase over several weeks. Store in a cool, dry place after opening. The caution states the product should be taken with at least a full glass of liquid, as taking it without enough liquid may cause choking, and it should not be taken by anyone with difficulty swallowing. The page lists certifications including Kosher (Triangle K), Non-GMO Project Verified, Safe Quality Food (SQF), USDA Organic, and Vegan, and states it is Certified Organic by QAI. It is labeled Made w/o Corn, Made w/o Dairy, Made w/o Eggs, Gluten Free, Low Sodium, Made w/o Nuts, Made w/o Soy, and Sugar Free. The ingredients are Organic Psyllium (Seed Husk). The product may contain traces of sesame and is not manufactured with yeast, wheat, gluten, soy, corn, milk, egg, fish, shellfish or tree nut ingredients, though it is produced in a GMP facility that processes other allergens. The page says it is packaged and quality tested in the USA, and the family and employee owned company notes the bottle is made from 100 percent PCR resin. Free shipping applies to orders over $50 in the 48 States and D.C. The product is listed in the Fiber and Prebiotics category and carries SKU 5966.

Study, Trial or Testing Result Summary

Members OnlyHuman studies

No ingredient findings were provided for this product, so we have no studies to report on psyllium husk for regularity or occasional constipation. The research notes say there are no human studies on this goal for its ingredients in the material we were given. The label lists psyllium as the only ingredient, but the amount per serving is not shown, so we cannot compare the dose with any studied dose. What we do have is a very large number of buyer ratings, about 29,000, with 88 percent positive and 6 percent negative. Buyers mainly report more regular, softer and easier bowel movements, and some mention less bloating. Several stress drinking plenty of water and starting with a small amount. A few with irritable bowel or sensitive digestion said it did not agree with them. Buyer experience is not the same as a controlled study, so until human study findings are added, the evidence for this goal should be treated as thin. Animal and cell studies are never counted.

Buyers mostly find NOW Certified Organic Psyllium Husk Powder an effective, affordable fiber supplement, with regularity the main benefit. It carries about 27,841 ratings across the stores. A few people found it clumpy or hard on a sensitive gut. Reviews of other forms of the product were left out, and this covers the powder only. **What buyers say it did for them:** Most praise is for bowel regularity and easier, softer movements. One reviewer wrote, "helping to relieve constipation and support regularity," and another said it was "Especially regulating for my system." Another bought it for a family member with constipation and saw improvement within days. Store summaries also mention less bloating and some results within a day. Bakers say it helps low-carb and gluten-free bread hold together: "My low carb bread stays together better and tastes more like normal bread." One reviewer reports lower fasting blood glucose, but that is a single person's experience. **What they complain about:** The main complaints are clumping and tolerance. One family found it "so clumpy making it difficult to swallow," preferred whole husk, and would not buy again. A reviewer with IBS warned, "avoid if your colon is sensitive to fibers," even after trying a very small dose. Another reviewer jokingly said it left them "pooping like a soft serve ice cream machine," which suggests a strong effect for some. Several reviewers stress that it needs plenty of water and that people should start with small doses to avoid choking or blockage. **Taste, smell and form:** It is generally described as unflavored and neutral, and as finely ground. One said it "mixes well with water or juice and has a neutral taste." Others are less enthusiastic: "Taste isn't too bad as I just usually chug it." The powder gels quickly, so one buyer noted it "has to consume fast." One likened the texture to applesauce but enjoyed it in diet lemonade or iced tea. Another suggested "maybe 1/3 juice to water ratio." Store summaries mostly say it mixes easily without clumping, which contrasts with the clumpy report above. The PureFormulas page also says it dissolves easily and compares it favorably with a poorly mixing earlier powder. **Value for money:** Buyers call it affordable and good value, saying a little goes a long way. One wrote, "This was the cheapest psyllium husk I came across, and a bonus-it's ORGANIC!" Another said NOW offers "consistent top quality at a fair price." Store summaries add that people like the organic certification, trust NOW's quality assurance and third-party testing, and received well-sealed packages on time. One PureFormulas reviewer said it tested very low in lead, and another noted it carries no California warning label. **Who it suits and who it did not:** It seems to suit people wanting a simple daily fiber boost for regularity, and low-carb or gluten-free bakers. One reviewer said it is "Perfect... for who don't have a much fiber in their diet." Those who liked it generally mix it into water, juice or smoothies and drink plenty of fluid through the day. It suited people with sensitive digestion or IBS less well. It also did not suit anyone who dislikes a fine powder's texture, such as the family that preferred whole husk. One PureFormulas reviewer, in contrast, said it works better for them than whole husk flakes.

Biohacker Summary

Members Only5 of 10 recommend it
5 of 10 biohackers on our panel recommend it

The panel leans positive on psyllium husk, though it is only a smaller ingredient in this product by the label's weighting, and the prompt calls it minor, so the panel's view is of psyllium itself. Of the ten, four recommend it and three more use it, mainly for lowering cholesterol, steadying blood sugar, easing digestion and adding fiber. Doses vary: 5 grams before meals, 10 grams mixed with yogurt, a quarter cup of the powder in homemade bread, a muffin baked with it before training, and one person taking 30 grams twice a day for cholesterol. Two of them warn that it can cause bloating, rapid fermentation or irritation of the gut at higher doses, and one adds that taking it without water risks a blockage and constipation, while another says it is good only if used strategically and well tolerated. Only three panelists spoke about it as anything other than psyllium, so no other ingredient gets weight here.

RAL Summary

Members OnlyTier 4 for Regularity: Long-Term Relief

Tier 3 needs some study support, but no human studies on regularity were given for psyllium, so the evidence here is thin despite strong reviews. So it is graded Tier 4, lower than the rules alone gave.

  • Emerging: not enough evidence to rank higher yet.
  • No human studies on this goal for its ingredients.

More Details

Members OnlyBody systems · Combine with · Possible side effects

Body systems: Digestive system

Combine with: To support regularity, take psyllium with plenty of water (at least 8 oz per serving) and start with a half serving, increasing gradually. Magnesium citrate or glycinate can add gentle stool-softening and motility support. A well-studied probiotic such as Bifidobacterium lactis or Lactobacillus plantarum may help balance gut flora and reduce gas. Peppermint oil (enteric-coated) and ginger can ease cramping and bloating in sensitive guts, and digestive enzymes may help with gas from food. Separate psyllium from medications and other supplements by 1-2 hours, since fiber can reduce their absorption.

Possible side effects: Some buyers with sensitive guts or irritable bowel reported discomfort, and some found it clumpy and hard to swallow. Reviewers warn it must be taken with plenty of water and started at small doses to avoid choking or blockage.
