ZenSulinOne of the things that sets ZenSulin apart from many blood sugar supplements is the simple fact that every active ingredient amount is printed openly on the label — no proprietary blends, no hidden dosages. This guide walks through each of the six active botanicals in the formula, with the exact dose, the role each ingredient traditionally plays and what the published research has examined.
For a broader overview of the product, see our full ZenSulin reviews.
Quick Snapshot of the Label

Other ingredients (the carrier base): water, glycerin and potassium sorbate.
1. Cinnamon (Cinnamomum cassia) Bark — 500 mg
Cinnamon cassia is the lead ingredient in ZenSulin and the largest single dose in the formula. Cassia cinnamon is one of the most well-studied botanicals in the natural blood sugar category — far more researched than the milder Ceylon cinnamon when it comes to glucose-related work.
The active compounds in cinnamon cassia bark include polyphenols and a polyphenol fraction sometimes referred to as MHCP (methylhydroxychalcone polymer), which has been examined for its role in supporting healthy insulin signaling. A 2003 study published in Diabetes Care by Khan et al. found that supplementation with cinnamon was associated with measurable changes in fasting glucose markers in their study group (PMID: 14633804).

2. Licorice Root — 174 mg
Licorice (Glycyrrhiza glabra or related species) has been used for centuries in Eastern and European herbal traditions. The active compounds include glycyrrhizin and a flavonoid called glabridin. Modern research has explored glabridin's role in supporting metabolic markers and antioxidant activity.
One important note: high doses of licorice root taken long-term may affect blood pressure in sensitive individuals. The amount in ZenSulin is moderate, but anyone with hypertension or who takes blood pressure medication should consult their doctor first.
3. Turmeric Root (Curcuma longa) — 75 mg
Turmeric is one of the most extensively studied botanicals in modern nutrition science. Its primary active compound, curcumin, is a polyphenol with documented antioxidant and inflammation-modulating activity (see Hewlings & Kalman, Foods, 2017 — PMID: 29065496).
In the context of blood sugar support, turmeric's antioxidant role is the most relevant. Elevated glucose levels can drive oxidative stress in cells, and polyphenol-rich ingredients help support the body's antioxidant defenses.
4. Coriander Seed — 50 mg
Coriander (Coriandrum sativum) is a culinary herb with a long traditional history of use for digestive comfort. Coriander seeds contain a range of antioxidant compounds and are associated in traditional practice with supporting healthy digestion of carbohydrates.
While coriander is the smallest of the four primary herbal extracts in ZenSulin at 50 mg, it provides complementary digestive support and antioxidant activity alongside the higher-dose ingredients.
5. Bitter Melon (Momordica charantia) — 0.8 mg
Bitter melon is one of the most well-known traditional botanicals in the blood sugar category, particularly in Ayurvedic and Traditional Chinese Medicine. Its active compounds include charantin and momordicin, which have been studied in clinical trials for their role in supporting glucose response.
A 2019 systematic review and meta-analysis by Peter et al. in the Journal of Ethnopharmacology reviewed multiple human trials of bitter melon in type 2 diabetes (PMID: 30385422).
It is worth noting that the bitter melon dose in ZenSulin — 0.8 mg of a 4:1 extract — is modest compared to doses used in some clinical trials, where higher amounts have been tested. The compound is included as part of the blend rather than as the lead ingredient.
6. Japanese Knotweed (98% Resveratrol) — 0.1 mg
Resveratrol is a polyphenol famous for its presence in red wine and grapes, and for its role in cellular health and longevity research. The Japanese knotweed extract used in ZenSulin is standardized to 98% trans-resveratrol, which is the highest-purity form commercially available.
Resveratrol has been studied extensively for its antioxidant activity and effects on cellular signaling pathways (Salehi et al., Biomedicines, 2018 — PMID: 30205595).
The 0.1 mg dose in ZenSulin is a small amount of a very high-purity extract. Resveratrol is one of those compounds where higher doses are not necessarily better — bioavailability and consistency of intake matter.
What's NOT in ZenSulin
Just as important as what is in the formula is what is not. ZenSulin contains:
- No caffeine or other stimulants
- No artificial colors, flavors or sweeteners
- No GMO ingredients
- No fillers or binders typical of capsule supplements
- No proprietary blends — every active dose is disclosed
How the Ingredients Work Together
The ZenSulin formula is designed around the idea that multiple botanicals targeting different aspects of glucose metabolism may work better together than any single high-dose ingredient. Cinnamon and bitter melon for insulin sensitivity; turmeric and resveratrol for antioxidant defense; licorice and coriander for digestive and carbohydrate support.
The strength of ZenSulin's formula is its transparency. With every dose printed openly on the label, consumers can evaluate whether each amount is meaningful — or compare it directly to research-backed dosages in published studies.
Frequently Asked Questions
The manufacturer produces ZenSulin in an FDA-registered, GMP-certified facility, which requires standardized ingredient testing and batch documentation.
Yes. 500 mg is in the same range as doses used in several published cinnamon trials, making it a meaningful amount rather than a token inclusion.
Both are concentrated extracts (4:1 and 98% standardized, respectively), so the milligram counts are smaller. Whether these doses are sufficient is reasonable to ask — for some users they may complement the larger doses; others may want higher amounts.
