Short answer: 1MD Nutrition's CholestMD is a two-capsule daily supplement built around 550 mg of Bergavit® citrus bergamot extract, plus 400 mg NE niacin, garlic, and olive leaf. It suits adults with borderline lipids who tolerate vitamin B3 and watch checkout settings closely. Two drawbacks stand out in 2026: its niacin blend can trigger warm, itchy skin flushing (and the bottle warns against use with acid reflux), while bulk discounts require auto-ship billing. Readers wanting a flush-free, one-time-purchase alternative with a full-year refund window may prefer plant sterols or Simple Promise's Cholibrium.

What is 1MD CholestMD?

CholestMD is an over-the-counter lipid supplement from California-based 1MD Nutrition, marketed alongside cardiologist Dr. Heather Shenkman. Each bottle holds 60 vegan cellulose capsules (30-day supply), taken as two capsules once daily with water and food.

Many 1MD CholestMD reviews online cite outdated formulas. Our NIH Dietary Supplement Label Database audit found two versions:

• Discontinued 2021 label (NIH DSLD ID 246725): Three capsules daily with 1,000 mg red yeast rice (10 mg monacolin K, chemically identical to lovastatin), pine bark, 20 mg nicotinic acid, and 380 mg niacinamide.

• Current 2026 label (NIH DSLD ID 274795, verified on 1MD's bottle): Drops red yeast rice and pine bark. Two capsules supply 550 mg Bergavit®, 400 mg NE niacin (niacinamide and niacin), 130 mg garlic 20:1 extract, and 50 mg olive leaf extract (40% oleuropein).

Removing monacolin K avoids FDA issues over unapproved statin-like compounds (FDA: Dietary Supplements), though current bottles act more gently than the 2021 version. Several top-ranking review blogs still list wrong doses (like 32 mg niacin or 500 mg olive leaf), so check the two-capsule panel.

How is it supposed to work?

1MD markets CholestMD around bergamot flavonoids to modulate hepatic cholesterol synthesis, niacin to support HDL, and garlic plus olive leaf polyphenols to limit LDL oxidation. Two clinical checks matter:

1. The "up to 67% LDL reduction" chart. 1MD's page shows a graph claiming "Up to 67% reduction of 'bad' LDL within 6 months" from a Bergavit® study (Toth et al., 2016). In that open-label study of 80 adults, total LDL cholesterol dropped ~20% (4.6 to 3.7 mmol/L); the 67% came from a tiny LDL-5 subfraction shifting from 0.3% to 0.1%. In a stricter 2024 double-blind RCT of 64 adults taking 150 mg/day bergamot flavonoids, LDL-C fell 11.5% over four months (Spina et al., 2024). Finished CholestMD capsules have not been tested in a trial.

2. The 400 mg NE niacinamide/niacin Catch-22. The label combines niacinamide and niacin into 400 mg NE (2,500% DV) without disclosing the ratio. Niacinamide has zero lipid-modifying effect; only nicotinic acid alters lipids (StatPearls, 2023). Yet nicotinic acid above 35 mg/day can cause skin flushing, while 2,000 mg/day extended-release niacin added to statins failed to cut vascular events in 25,673 patients (HPS2-THRIVE, 2014).

Ingredients: what the research actually says

Here is how each CholestMD ingredient compares against human clinical trials:

Ingredient (2 capsules)	1MD claim	Human research (study dose vs. CholestMD)	Evidence
Bergavit® Bergamot — 550 mg (25% flavonoids = 137.5 mg)	Healthy LDL, HDL & triglycerides	150 mg/day flavonoids cut total cholesterol 8.8% and LDL-C 11.5% in 64 adults (Spina et al., 2024). Supplies ~92% of study dose.	Moderate
Niacin (Niacinamide & Niacin) — 400 mg NE (2,500% DV)	HDL & lipid metabolism	Ratio not disclosed. Niacinamide doesn't shift lipids (StatPearls, 2023); 2 g/day niacin showed no event drop (HPS2-THRIVE, 2014).	Limited
Garlic Bulb 20:1 — 130 mg	Circulation & lipid support	Across 39 RCTs ($n=2,298$), garlic $>2$ months cut LDL-C ~9 mg/dL (Ried et al., 2013). Allicin yield not disclosed.	Moderate
Olive Leaf Extract (40% Oleuropein) — 50 mg (20 mg oleuropein)	Arterial & lipid support	In 60 men (136 mg/day oleuropein), phenolic-rich olive leaf extract lowered blood pressure and plasma lipids, cutting LDL-C 0.19 mmol/L (Lockyer et al., 2017). Supplies ~15% of trial dose.	Limited

Takeaway: Bergavit® carries this formula at 92% of its clinically studied flavonoid dose, whereas olive leaf is heavily underdosed and the niacin blend adds flushing risk without transparent nicotinic acid dosing.

Potential side effects & who should skip it

Every active lipid supplement carries side-effect and interaction risks:

• Niacin skin flushing: Nicotinic acid dilates surface capillaries within 30–120 minutes, causing temporary redness, heat, or itching. 1MD's FAQ notes flushing can start within hours.

• Acid reflux, gastritis, and surgery warning: 1MD's bottle states: "Do not use 7 days prior to surgery. Not recommended for persons with acute or chronic stomach inflammation or acid reflux." Garlic and high-dose vitamin B3 can irritate gastric tissue, and garlic slows platelet clumping.

• Drug interactions: Ask your physician first if you take blood thinners (warfarin, apixaban, clopidogrel, aspirin), blood pressure or diabetes medications, or statins.

• Liver, gout, and glucose concerns: High-dose niacin can raise liver enzymes, uric acid, and blood glucose (StatPearls, 2023; HPS2-THRIVE, 2014). See our 1MD LiverMD audit for broader 1MD context. Pregnant or nursing women should skip it.

Pros and cons

Pros:

• Standardized 550 mg Bergavit® (137.5 mg flavonoids) matches ~92% of human trial dosing.

• Red-yeast-rice-free (no hidden lovastatin-like monacolin K).

• Two vegan, allergen-free capsules once daily; 90-day return policy.

Cons:

• Finished CholestMD formula has no direct clinical trial.

• Undisclosed niacinamide/niacin split at 400 mg NE can trigger skin flushing.

• Underdosed olive leaf extract (20 mg oleuropein vs. 136 mg in trials).

• Zero one-time bundle discount ($54 flat), nudging buyers into auto-ship plans.

• Label warns against use with acid reflux, gastritis, or within 7 days of surgery.

What customers say: CholestMD reviews and complaints

1MD's sales page cites internal survey stats (70% reporting cholesterol benefits) — treated strictly as testimonials on the seller's site, not independently verified. On Walmart and Trustpilot, ratings average ~4.0–4.5 stars for capsule convenience and gradual lab support alongside diet changes.

On the Better Business Bureau (BBB), 1-star Trustpilot posts, and TopConsumerReviews, cholestmd reviews and complaints highlight three buyer anecdotes:

• Auto-ship billing friction: Dozens of BBB complaints cite unintentional "Subscribe & Save" enrollment and cancellation hurdles.

• Niacin warmth and reflux: Sensitive buyers describe hot facial flushing within an hour or garlicky heartburn.

• Modest solo shifts: On Reddit's r/Cholesterol, commenters note bergamot helps modestly unless paired with lower saturated fat and soluble fiber.

CholestMD vs. gentler alternatives

Ranked strictly by human clinical evidence, here is how CholestMD compares with two alternatives plus daily habits:

Option	Daily actives	Clinical LDL evidence	Tolerability & billing	Cost
1. CholestOff Plus (Top evidence)	1,800 mg plant sterols/stanols	Strong — 124 RCTs show 6–12% LDL-C drop (Ras et al., 2014)	No flush; porcine gelatin; 4 large softgels	~$25–$32
2. 1MD CholestMD	550 mg Bergavit®, 400 mg NE niacin, garlic, olive leaf	Moderate — Bergavit® trials show 11.5–20% LDL drop	Possible flush & reflux; auto-ship discounts	$43.20–$54
3. Cholibrium (Gentler one-time)	1,330 mg 10-mushroom blend	Limited — Shiitake RCT cut triglycerides 10% (Spim et al., 2021); Reishi review showed no LDL drop (Klupp et al., 2015)	Flush-free, vegan, one-time billing, 365-day refund	$39–$59

• CholestOff Plus wins on clinical proof: Over 100 trials confirm phytosterols reduce gut cholesterol absorption (Ras et al., 2014), though four gelatin softgels deter vegans.

• Cholibrium wins on gentle, no-subscription terms: Taken 20–30 minutes before a meal, it skips niacin and garlic. Still, six of its ten mushrooms share a 266 mg blend (individual doses not disclosed), human mushroom LDL data remain limited, and blood-thinner or kidney-stone patients need doctor clearance. See our Cholibrium safety audit, 2026 Cholibrium review, mushroom cholesterol comparison, and Cardio Clear 7 vs. VenoPlus 8 vs. Cholibrium guide.

• Food-first habits: Keeping saturated fat under 6–7% of calories, eating 5–10 g/day of soluble fiber (oats, psyllium, beans), and brisk walking 150 minutes weekly remain foundational (NHLBI, NIH).

Our verdict

1MD CholestMD earns 3.3 out of 5. Its 550 mg Bergavit® dose is well-supported, yet the undisclosed 400 mg NE niacinamide/niacin blend adds flushing risk and 1MD locks bulk discounts behind recurring subscriptions.

Pick USP-verified plant sterols plus soluble fiber for maximum OTC clinical proof. For a gentler, niacin-free vegan capsule with one-time ClickBank billing, free US shipping, and 365 days to check follow-up labs with your physician, Cholibrium is the lower-friction choice.

FAQ

Does 1MD CholestMD really help lower LDL cholesterol? Its core extract, Bergavit®, lowered LDL-C by 11.5% in a 4-month RCT (Spina et al., 2024) and ~20% in a 6-month open-label study (Toth et al., 2016). Finished CholestMD capsules remain untested.

Does CholestMD cause niacin skin flushing? Yes, it can. Each serving supplies 400 mg NE of niacinamide and niacin; nicotinic acid above 35 mg can trigger temporary warmth, redness, or itching within hours.

What are the main complaints about 1MD CholestMD billing? Most BBB and 1-star Trustpilot complaints cite unwanted "Subscribe & Save" renewals, since one-time orders cost $54 flat per bottle with zero multi-pack discount.

Does 1MD CholestMD still contain red yeast rice? No. While 1MD's 2021 three-capsule label (NIH DSLD ID 246725) contained red yeast rice, the current two-capsule formula (ID 274795) has none.

Can I take CholestMD or Cholibrium with a prescription statin? Consult your prescribing doctor first. Adding high-dose niacin to statins increased adverse events without cutting vascular events in large trials (HPS2-THRIVE, 2014).

How does Cholibrium's refund policy compare with 1MD Nutrition's? 1MD offers a 90-day return window, while Simple Promise covers one-time Cholibrium orders for 365 days, including empty bottles mailed back to Maryland (return postage paid by buyer).

When to see a doctor

Never replace prescribed heart care with supplements. See a doctor — and never stop a statin solo — if your LDL-C is 190 mg/dL or higher, you have diabetes, hypertension, liver or kidney disease, early family heart disease, or statin muscle pain (NHLBI, NIH). Call 911 immediately for chest pressure, pain spreading to the arm, jaw, neck, or back, sudden breathlessness, or slurred speech.
