Insulin Resistance
& Blood Sugar Control
A targeted stack of rigorously researched compounds — each working through distinct mechanisms to improve insulin sensitivity, reduce fasting glucose, and support long-term metabolic health.
The Science
Why Insulin Resistance Needs
a Stack Approach
No single supplement addresses insulin resistance through all its pathways. The strongest clinical protocols combine compounds working through distinct mechanisms — each layer addressing a different piece of the same metabolic problem.
The Collection
Evidence-Backed Supplements
The most rigorously studied natural compound for insulin resistance. Activates AMPK — the cellular energy master switch — improving how muscles and liver respond to insulin. Multiple RCTs show reductions in fasting glucose, HbA1c, and HOMA-IR. Nano-formulation achieves 3× higher bioavailability than standard capsules.
AMPK Activation · Hepatic Glucose ControlRequired for over 300 enzymatic reactions, including insulin receptor signalling and GLUT4 translocation — the mechanism by which glucose enters muscle cells. Research consistently links insulin resistance and pre-diabetes with low serum magnesium. Zero oxide fillers; only chelated bisglycinate.
GLUT4 Support · Overnight Insulin SensitivityA comprehensive Ayurvedic stack with independently researched mechanisms. Jamun seed extract inhibits starch-to-sugar conversion. Ashwagandha reduces cortisol — a hormone that directly elevates fasting glucose. Shatavari supports pancreatic function. Combined with pectin for sustained release.
Adrenal · Pancreatic · Digestive SupportMulberry Leaf Extract (DNJ — 1-deoxynojirimycin) with berberine inhibits carbohydrate-digesting enzymes, providing targeted post-meal support. Particularly effective before rice, roti, and other high-carbohydrate Indian meals that cause rapid glucose elevation.
Enzyme Inhibition · Glucose Spike ReductionPCOS is driven in significant part by insulin resistance — elevated insulin stimulates excess androgen production, disrupting ovulation and hormonal balance. Addresses both the hormonal and insulin-related aspects of PCOS. Berberine has specific clinical evidence for reducing testosterone and improving ovulation in women with PCOS.
Hormonal Balance · Androgen ModulationStacking Protocol
Recommended Daily Stack for Indians
Each supplement targets a distinct pathway. Together they provide comprehensive coverage — from fasting glucose and overnight sensitivity to post-meal spikes.
| Supplement | When to Take | Primary Mechanism |
|---|---|---|
| Holistic Berberine Tablets | With breakfast + dinner | AMPK activation, fasting glucose reduction |
| Magnesium Glycinate Capsules | 30–60 min before bed | GLUT4 support, overnight insulin sensitivity |
| Holo Diabetis Tablets | 30 min after meals | Multi-herb metabolic + pancreatic support |
| Carb Cutter | 30 min before high-carb meals | Post-meal glucose spike reduction |
| Narie PCOS & PCOD Care | As directed | Insulin-driven hormonal balance (women) |
Why ZeroHarm?
Manufactured to a Different Standard
Most berberine supplements in India are absorbed at less than 5% before stomach acids degrade them. Our nano-formulation and chelated minerals deliver therapeutic absorption every batch independently verified.
Nano-Formulated Berberine
Reduced particle size increases surface area and stability — 3× higher bioavailability vs standard extracts.
100% Chelated Magnesium
Zero magnesium oxide, zero buffering agents. Only chelated bisglycinate with clearly stated elemental content.
NABL Lab Tested
Every batch independently tested at accredited laboratories for potency, heavy metals, and microbial safety.
GMP + AYUSH Certified
Manufactured in a GMP-certified, FSSAI-approved, AYUSH-certified facility using aqueous extraction — no harsh solvents.
Glass Packaging
Preserves efficacy in India's humid conditions — unlike plastic-bottled supplements that degrade significantly faster.
100% Vegetarian
All supplements are plant-based. Capsule shells are made from vegetable cellulose, not gelatin.
FAQs
Frequently Asked Questions
Which supplement is best for insulin resistance in India?
Berberine has the strongest human clinical evidence for improving insulin sensitivity, reducing fasting glucose, and lowering HOMA-IR scores. For best results, pair it with Magnesium Glycinate — which addresses the magnesium deficiency present in most people with insulin resistance. ZeroHarm's Holistic Berberine is nano-formulated for high bioavailability, making it the most effective berberine supplement available in India.
How long does berberine take to lower blood sugar?
Most people see measurable improvements in fasting glucose within 4–8 weeks of consistent use. HbA1c reductions typically appear after 12 weeks. Results improve significantly when combined with reduced refined carbohydrate intake and regular physical activity.
Can I take berberine and magnesium glycinate together?
Yes. These two supplements work through entirely different pathways and are commonly recommended together in evidence-based protocols. Berberine activates AMPK and reduces hepatic glucose production; magnesium glycinate supports GLUT4 translocation and insulin receptor function. Take berberine with meals and magnesium at night.
Is berberine safe for daily use?
Berberine is generally safe at doses of 500–1500 mg/day when used as directed. It may potentiate the effects of diabetes medications — consult your doctor if you are on metformin, sulfonylureas, or insulin to avoid hypoglycaemia.
What is HOMA-IR and can supplements improve it?
HOMA-IR (Homeostatic Model Assessment of Insulin Resistance) is a blood test calculation using fasting glucose and fasting insulin levels to quantify insulin resistance. Berberine, magnesium glycinate, and chromium have each been shown in clinical trials to reduce HOMA-IR scores over 8–12 weeks of supplementation.
Is this collection relevant for PCOS?
Yes. Insulin resistance is a core driver of PCOS in the majority of affected women. Berberine, magnesium, and the Narie PCOS & PCOD Care formula are all relevant. Berberine has specific clinical evidence for reducing testosterone and improving ovulation in women with PCOS.
Are these supplements vegetarian?
Yes. All ZeroHarm supplements in this collection are 100% plant-based and vegetarian. Capsule shells are made from vegetable cellulose, not gelatin.
