Nitric Oxide Support Capsules with L-Citrulline & Beetroot

Nitro Ox provides 3000mg of L-Citrulline and 500mg of beetroot extract (10:1) per serving. £12 for 150 capsules.

Two Ingredients, Two Pathways

Nitric oxide is a short-lived signalling molecule the body produces continuously, by two broad routes. The first is enzymatic, using the amino acid L-arginine as substrate. The second involves dietary nitrate, which is reduced to nitrite by bacteria in the mouth and subsequently to nitric oxide in the body.

L-Citrulline feeds the first pathway. It converts to L-arginine in the body — and, counter-intuitively, supplemental citrulline raises circulating arginine more effectively than supplemental arginine does, because arginine is heavily metabolised on first pass through the gut and liver.

Beetroot feeds the second. It is among the more concentrated dietary nitrate sources.

A Note on Claims

Neither L-citrulline nor beetroot has an authorised health claim on the GB Nutrition and Health Claims Register. We therefore describe both ingredients factually and make no claims about performance, blood flow or exercise outcomes. Almost every pre-workout on the UK market does otherwise; that is a regulatory choice they have made, not a scientific one.

The Ingredients

• L-Citrulline — 3000mg per serving.
• Beetroot Extract — 500mg per serving at 10:1 concentration.

Suggested Use

Take as directed on the label. If you use it around training, take it in advance rather than immediately before.
