Each of these herbs has a documented role in Ayurvedic practice, and a paper trail on PubMed. Diabec puts all six in a single capsule, made in one WHO-GMP facility.
Our Ingredients
Real Herbs. Real Research.
Six Ayurvedic herbs covering three complementary pathways: how sugar enters, how cells use it, and how cells are protected.
Research cited refers to traditional and preclinical evidence on the individual botanicals, not on Diabec as a finished product. Diabec is a food supplement, not a medicine.
1
How Sugar Enters
Compounds in Gymnema and Bitter Melon are studied for their interaction with sugar-absorption receptors in the gut.
2
How Cells Use Glucose
Fenugreek and Enicostemma contain 4-hydroxyisoleucine and iridoid glycosides, studied for their role in cellular glucose uptake.
3
How Cells Are Protected
Anthocyanins from Jamun and compounds from Neem provide antioxidant activity in the same cells doing the metabolic work.
Gymnema Sylvestre
Gymnema sylvestre (Retz.) R. Br.
Known as "Gurmar" (sugar destroyer) in Sanskrit. Gymnemic acids are traditionally used to support healthy glucose metabolism and may help reduce sugar cravings by binding to sweet-taste receptors.
Source: Khan et al., Frontiers in Pharmacology, 2019 · PMID 31736747
Bitter Melon
Momordica charantia L.
Rich in polyphenols and alkaloids that support normal glucose uptake and utilisation. Meta-analysis of 18 RCTs with 1,100+ participants.
Fenugreek
Trigonella foenum-graecum L.
One of the highest concentrations of soluble fibre in nature. Contains 4-hydroxyisoleucine. Traditionally used in Ayurveda alongside meals.
Source: American Journal of Clinical Nutrition, 1998 · PMID 9519714
Jamun
Syzygium cumini (L.) Skeels
Indian blackberry with high anthocyanin concentrations - plant pigments studied for their antioxidant activity. Traditionally used in Ayurvedic practice.
Neem
Azadirachta indica A. Juss.
Over 100 documented phytochemical compounds, including nimbidin and quercetin. Studied for its role in metabolic and immune support.
Source: Journal of Pharmacy and Pharmacology, 2022 · PMID 34562010
Enicostemma
Enicostemma littorale Blume
A herb long valued in Ayurveda. Iridoid glycosides are traditionally used to support healthy blood sugar metabolism already within the normal range.

The Science of Combined Herbs
Why a Combined Formula?
Six herbs working together through complementary pathways deliver broader support than any single ingredient alone.
-
Three complementary pathways, one capsule.
Each herb covers a different role: sugar absorption, cellular glucose response, antioxidant protection.
-
Standardised extracts, not raw powder.
Gymnema to 25% gymnemic acids. Fenugreek to 50% saponins. The same dose in every capsule.
-
One facility. One standard.
Made in a single WHO-GMP certified facility, audited annually. Not six different manufacturers with six different quality regimes.
-
Around the price of a tea bag a day.
Buying six standardised herb extracts separately runs well over £80 a month. The 3-month pack puts all six together for about £0.50 a day.
How It Works
Three Capsules. Three Meals. That's the Whole Routine.
No complicated routines. No appointments needed. Just capsules after meals.
1
Take After Meals
Take 1-2 capsules after breakfast, lunch, and dinner.
2
Herbs Go to Work
Six Ayurvedic herbs work together to support your body's natural glucose metabolism.
3
Experience Daily Support
As part of a balanced lifestyle, Diabec supports your wellness goals.
Why We Built Diabec
Six Bottles Became One.
"Our family watched relatives juggle six supplement bottles daily. So we combined the six most-researched Ayurvedic herbs into one capsule, sourced in India, shipped from the UK. One bottle. One routine."
Jaysh, founder of Diabec. NIBARTECH LTD, London.

Diabec is generally well-tolerated. All six herbs have centuries of traditional use and established safety profiles. Some people may experience mild digestive adjustment during the first few days, such as mild bloating, gas, or loose stools - this typically resolves as your body adapts. Bitter Melon and Fenugreek are the most common sources of temporary digestive effects. If you are taking diabetes medication, consult your healthcare provider before use, especially if you are taking any medications. Diabec is not recommended during pregnancy or breastfeeding without medical guidance. If you experience any persistent discomfort, discontinue use and consult your healthcare provider.
We always recommend consulting your healthcare provider before combining Diabec with any medication, especially if you take prescription medications. Consult your healthcare provider before combining Diabec with any medications.
