Dihydroberberine is the gut-converted form your body absorbs more readily — so the daily amount is a fraction of a conventional berberine regimen. 250 mg patented GlucoVantage® DHB + 250 mg true Ceylon cinnamon, in one small capsule a day. No miracle-drug hype. Just the mechanism, done right.†
Berberine has a well-known problem: very little of it is actually absorbed, so people take large doses and pay for it with their stomach. Dihydroberberine is the reduced form — the body converts it back to berberine after absorption, which is why a far smaller dose can be used.*
Commonly split across two or three capsules — the amount many people find hard on the stomach.†
One small capsule. 250 mg patented GlucoVantage® DHB with 250 mg true Ceylon cinnamon.
Food, movement and a routine you actually keep. This is a small, well-absorbed addition to that — not a replacement for any of it.†
Same mechanism, a fraction of the daily amount — one small capsule instead of three large ones.†
The dose here is 250 mg because of absorption, not because the formula is weaker.*
It supports healthy glucose metabolism alongside the meals and training you already plan.†
Patented GlucoVantage® and true Ceylon cinnamon, both disclosed by weight, with this lot’s certificate above.
And who it is not for. If you take glucose-lowering medication, speak to your doctor before starting. This is a dietary supplement — it does not treat, prevent or manage any condition.†
Most brands say “third-party tested” and link a PDF nobody opens. Here is what our certificate actually measured, and what the numbers mean.
| What was tested | Method | Label says | Lab found | Status | Meaning |
|---|---|---|---|---|---|
| DihydroberberineGlucoVantage® | HPLC | 250 mg/capsule | 255 mg/capsule | PASS | Slightly above the labeled amount. |
| Ceylon CinnamonCinnamomum verum | HPLC | 250 mg/capsule | 251 mg/capsule | PASS | Meets the labeled amount. |
| IdentityIs it really DHB? | HPLC | Positive for DihydroBerberine | Confirmed | PASS | The material is what it claims to be. |

A separate certification from the Clean Label Project, which tests finished products for industrial and environmental contaminants — heavy metals, pesticide residues and plasticizers — rather than just the active ingredients. Certificate SPP0039-2024K-22, issued to Vinatura Supplements LLC, Supplements V1, effective 22 November 2024. The current issue lists DihydroBerberine with Ceylon Cinnamon by UPC among the certified products.
Open the CLP certificate →Certificates are issued per manufacturing lot; the lot you receive may differ. A third certificate — identity and microbial testing, Lot 2126010, January 2026 — is also available.
Dihydroberberine is a form of berberine chosen for how it is absorbed, paired here with Ceylon cinnamon. One capsule a day, taken consistently.
250 mg per capsule. The species named on the label and confirmed by HPTLC on the certificate, at a dose worth pairing rather than a dusting.
The cheaper and far more widely used species. Most supplement and supermarket “cinnamon” is cassia, and labels rarely say which one you are getting.
“I really like that the capsules are CLP-certified. The package contains 30 capsules, which is a month’s supply at the standard dosage. The product is easy to swallow, has no unpleasant taste and most importantly, I have noticed positive changes.”
Kate · Verified buyer · November 2025“Great quality supplement! I love that it’s tested for purity in the USA and includes a third-party certificate of analysis. It’s been gentle on my stomach and keeps my digestion smooth. Highly recommend.”
Carli · Verified buyer · February 2026“I’ve tried regular berberine before, but this one with GlucoVantage is on another level… less bloating and overall better digestion. I love that it’s vegan and includes Ceylon cinnamon. Definitely feels more absorbable than other brands I’ve used — no side effects.”

* 5× more absorbable than standard berberine, as claimed by GlucoVantage®. Dihydroberberine is the gut-converted metabolite of berberine; pharmacokinetic studies on GlucoVantage® have shown several-fold higher plasma berberine exposure than standard berberine HCl, which is why a smaller daily dose is used.
