Quick answer: ColestZen is a two-capsule daily blend of 18 herbs and nutrients marketed for cholesterol, heart and blood sugar support. Prices run $49 to $79 a bottle with a 60-day guarantee. Its licorice content deserves a doctor's review.

That verdict is based only on the official ColestZen sales page and public health sources. We did not test ColestZen, and nothing below is a promise of results.

What is ColestZen?

ColestZen is a dietary supplement sold online through its own website. The headline on the official page presents ColestZen as a natural option for supporting healthy cholesterol, heart health and blood sugar levels, with repeated references to circulation and "cleaner arteries."

The page describes the product as capsules, although one section calls it a tablet. The directions say to take two capsules a day with a large glass of water, in the morning according to one section. The page does not state how many capsules are in a bottle, but its packages are labeled as 60-, 90- and 180-day supplies for 2, 3 and 6 bottles, which works out to about a month per bottle.

What ingredients are in ColestZen?

According to the official website, ColestZen contains 18 ingredients split into two groups. No amounts are given in the text, so you cannot tell how much of each one is in a serving.

Reading that list, ColestZen looks more like a blood-sugar formula than a classic cholesterol product. Bitter melon, gymnema, banaba, mulberry, cinnamon and chromium are ingredients usually marketed for glucose support.

What does the research say about ColestZen's main ingredients?

There are no published trials of the ColestZen formula itself that we could find linked from the official page. The page includes a reference list for individual botanicals, but those studies are not about this product. Here is what neutral sources say about some of the ingredients:

• Cinnamon: a 2019 review of 16 studies found cinnamon supplements helped reduce fasting blood glucose and insulin resistance in people with prediabetes and type 2 diabetes, but doses and products varied widely (NCCIH, Diabetes and Dietary Supplements).
• Chromium: a 2022 review suggested chromium may help HbA1c and fasting glucose in people with type 2 diabetes, according to the same NCCIH summary. The NIH Office of Dietary Supplements has a full fact sheet.
• Alpha lipoic acid: NCCIH notes that a 2019 review of 10 studies found it was no better than placebo for managing type 2 diabetes.
• Magnesium: people with higher magnesium intake from food tend to have a lower risk of diabetes; supplement evidence is mixed (ODS magnesium fact sheet).

None of these sources describe these ingredients as proven cholesterol treatments.

Why does the licorice in ColestZen matter for blood pressure?

Licorice root contains glycyrrhizin. NCCIH warns that glycyrrhizin can cause serious effects such as irregular heartbeat, especially in large amounts or with long-term use, and that even small amounts have been linked to severe effects in people with hypertension, heart or kidney conditions, or high salt intake. NCCIH also lists licorice among herbs that may raise blood pressure.

The ColestZen page does not say whether its licorice extract is deglycyrrhizinated (DGL) or how much is in each capsule. For a product marketed to people worried about heart health, that is a meaningful gap. If you have high blood pressure, ask your doctor or pharmacist to look at the ColestZen label before you take it.

Can ColestZen interact with medications?

Several ColestZen ingredients deserve a pharmacist's look:

• Diabetes medicines: cinnamon, chromium, bitter melon and gymnema are all discussed for lowering blood sugar. Combined with insulin or other glucose-lowering drugs, that could add up.
• Blood thinners: vitamin E in supplement form may increase bleeding risk with anticoagulants, according to the ODS vitamin E fact sheet.
• Blood pressure medicines and diuretics: licorice can raise blood pressure and lower potassium, which may work against these drugs.
• Statins: the ColestZen page does not mention statins. One customer story on the page refers to medication being reduced, but that is an anecdote, not evidence. Never cut back a statin without your prescriber.

The ColestZen FAQ itself tells buyers to show the bottle to their doctor before taking it, which is good advice. More detail is in our heart medication interactions guide.

How much does ColestZen cost?

These prices were shown on the official ColestZen order section in October 2026:

The 6-bottle package also comes with two digital bonus guides, named on the page as "One-Day Artery Cleanse Kickstart" and "The Energy Suppression Code." The struck-through "original" prices on the page are marketing reference prices; we would not rely on them.

What is the ColestZen refund policy?

The official FAQ describes a 60-day money-back guarantee and says bottles can be returned even if empty. Before ordering a large bundle, confirm the return address and whether shipping costs are refunded, because the page text does not spell that out.

Who might consider ColestZen, and who should avoid it?

ColestZen may interest adults without blood pressure problems who want a single capsule covering several popular blood-sugar and antioxidant ingredients, and who have cleared it with their clinician.

ColestZen is a poor fit, or needs a doctor's approval first, for:

• people with high blood pressure, heart disease, heart rhythm problems or kidney disease (because of licorice);
• anyone taking insulin, metformin or other diabetes drugs;
• people on blood thinners or scheduled for surgery;
• pregnant or breastfeeding women (NCCIH says large amounts of licorice during pregnancy are unsafe, and little is known about licorice while breastfeeding);
• anyone under 18.

What are the downsides of ColestZen?

• No amounts are disclosed for any of the 18 ingredients.
• Licorice is included without stating whether glycyrrhizin has been removed.
• The page mixes "capsule" and "tablet" wording.
• The page states the product is made in an FDA-registered, GMP-certified facility. Registration with the FDA is not the same as FDA approval, and dietary supplements are not approved by the FDA before sale.
• Sold only online, with the best per-bottle price tied to a six-bottle purchase.
• No published clinical trial of the ColestZen formula itself.

How does ColestZen compare with other cholesterol supplements?

If your main concern is LDL cholesterol, a single-ingredient bergamot product is closer to the research. See ColestZen vs Bergamot Plus, or compare ColestZen with a circulation formula in ColestZen vs CardioShield. Our bergamot and cholesterol guide explains what reviews have found.

Bottom line on ColestZen

ColestZen is really a broad metabolic blend with a heart-health headline. The ingredient list is long but undosed, and licorice makes it a product to discuss with your doctor first, especially if your blood pressure is anything above normal.
