Red yeast rice is the only ingredient, at 900 mg a day, which is above the lowest dose that worked in studies. A 2022 pooled analysis of 131 trials with 13,062 adults ranked it among the two most effective supplements for lowering total and bad cholesterol, by about 36 mg per deciliter for total cholesterol [1]. A 2024 pooled analysis of 14 double-blind trials found bad cholesterol fell by about 36 mg per deciliter, without frequent or threatening side effects [2]. A 2023 pooled analysis found lower total cholesterol, bad cholesterol and triglycerides, with a small rise in good cholesterol [3]. An earlier analysis of 13 placebo-controlled trials found lower blood fats but no clear rise in good cholesterol [4]. In heart attack survivors, 1,200 mg a day, a bit more than one serving here, lowered bad cholesterol and reduced repeat heart attacks [5]. A trial of nearly 5,000 heart attack patients over about 4.5 years found fewer heart events and deaths [6]. In a 12-week trial, 51 percent reached their cholesterol target. As little as 200 mg a day helped in a small trial. One 28-day trial found no benefit over placebo. Animal and cell studies are never counted.

Review Totals and Summary
Members Only1,553 reviews · 93% positive
Overall, buyers of Thorne Choleast-900 capsules are largely positive: about 997 ratings across the stores, and most reviewers with stars gave 4 or 5. The strongest theme is that it lowered cholesterol numbers for people who tried it. **What buyers say it did for them:** Many report falling numbers on blood tests. One says "My LDL dropped 50 points in 3 months!" while taking two pills a day, and another reports "my LDL dropped about 30 points" after about three months. One reviewer's cholesterol went "from 246 to 187," and they said their doctor was pleased. Several say it helped them avoid meds, such as "eliminated the need for meds." One person who has taken it for over a year says their numbers came down. Another says it "helped me keep my cholesterol level low." Several mention no side effects, and one says "It is effective with no side effects." **What they complain about:** There are very few complaints. One reviewer worries that quality may slip now that Thorne has been bought: "concerned now that Thorne was bought up." A few reviewers say it is too early to judge, including the 3 star reviewer, who is a month in and waiting on a blood test. One 1 star rating comes with text saying the product "works when other brands didn't," so the low rating looks at odds with the comment. No written complaints about taste, size or price appear in the reviews. **Taste, smell, pill size or form:** Nobody mentions taste or smell. One reviewer likes that "it's not big" and that they need only one a day. Others describe taking two a day, such as 900 mg twice daily after meals, so the dosing people follow varies. Only the capsules are covered here; reviews of other forms were left out. **Value for money:** Price is not discussed in the reviews. One buyer appreciates getting it through Walmart, with speedy delivery and no wait of "2 weeks to a month." Others point to the brand's quality and testing: "Thorne is a highly recommended supplement brand." **Who it seems to suit and who it did not:** It seems to suit people who want a red yeast rice supplement to manage cholesterol, often alongside diet changes. One reviewer calls it "one of the few effective RRY on the market" when combined with diet. Several were steered to it by a doctor or primary care physician, and some were trying to avoid meds or other prescriptions. One reviewer had tried other things, including Thorne's fiber, before this helped "tremendously." Nobody clearly reports that it failed to work. People who want proof of results may need to wait: some newer users have not yet had bloodwork, and one is watching their results to see whether quality holds up under the new ownership.
Biohacker Summary
Members Only10 of 10 recommend it
Eight of the ten panelists spoke about red yeast rice, the main ingredient, and the group is cautious rather than enthusiastic: one recommends it, two use it, and the rest are neutral or warn. Most take it to lower cholesterol and LDL, with some also pairing it with berberine, niacin, vitamin E and vitamin K, and several say to add CoQ10 because it may be depleted. Doses came up only in comparisons, with about 2400 milligrams likened to a standard dose of a cholesterol med and a review citing 200 to 4800 milligrams a day, and one person takes it at night. Cautions were common: it acts much like a med, unregulated products may be unsafe or unreliable, one advises avoiding it in pregnancy, and one panelist stopped after follow-up scans showed it did not slow plaque buildup.

Body systems: Cardiovascular system, Metabolic system
Combine with: Because red yeast rice contains monacolin K (chemically identical to lovastatin), it can deplete coenzyme Q10, so pairing it with CoQ10 or ubiquinol (100-200 mg daily) is a sensible addition. Omega-3 fish oil (EPA/DHA) helps lower triglycerides, which complements the LDL-lowering effect of red yeast rice and plant sterols. Soluble fiber such as psyllium husk or beta-glucan from oats further reduces LDL by binding bile acids. Bergamot extract, berberine, or niacin can offer additional lipid support, though berberine and niacin should be used with medical guidance. Milk thistle or other liver support may be reasonable given that monacolins can affect liver enzymes. Avoid combining with prescription meds, and consult a clinician about interactions, especially with grapefruit, fibrates, or other meds. Pregnant or nursing women should not use it, and periodic liver enzyme and lipid monitoring is advisable.
Possible side effects: Studies found it well tolerated, without frequent, serious or threatening side effects. Reviewers who mention side effects say they had none.
