1000mg per serving. Nitric-oxide precursor. Helps your blood do what your willpower asks of it.
\nThis batch sold out. Next batch leaves Bangalore in 2–3 weeks. Tap “Notify me when back” above. In the meantime, our BCAA Watermelon carries 1g of L-Citrulline per serving.
\nZenith Sports L-Citrulline delivers 1000mg of pure L-Citrulline per 2-capsule serving. Your kidneys convert it to L-Arginine, which produces nitric oxide — the molecule that widens blood vessels so more oxygen and nutrients reach working muscles. Result: stronger pumps, more reps before failure, faster recovery, no stimulants. 60 vegetarian capsules per bottle. Manufactured in Bangalore at an FSSAI-approved (License 11215332000675), GMP-certified facility by Medizen Labs.
\nCitrulline isn't a stimulant. It doesn't fire you up. It rebuilds the road your blood travels on.
\nEach delivers 500mg of fermentation-derived L-Citrulline inside a vegetarian HPMC shell. No fillers, no binders. The amino acid enters the bloodstream from the small intestine.
\nUnlike supplemental L-Arginine — which the gut and liver break down before it reaches the bloodstream — L-Citrulline bypasses first-pass metabolism. Plasma arginine rises more predictably.
\nIn endothelial cells lining your blood vessels, the enzyme eNOS converts L-Arginine to nitric oxide — a vasodilator. Vessel walls relax. Blood flows faster and farther.
\nWorking muscle gets more oxygen per beat. Waste clears faster. Result: fuller pumps, deeper rep ranges before failure, faster bounce-back.
