Watermelon

It's the most researched ingredient in sports nutrition, with 30 years of use and hundreds of human studies behind it. The whole protocol is one sachet a day, every day. No loading phase, no cycling, no timing.

How to take it: tear, tip onto your tongue, done. Any time of day. That's your 3g done.

Who it's for: people who train, people who eat little or no meat, women (naturally lower stores than men), anyone over 40 who wants to hold onto muscle, and anyone who's bought a tub and never finished it.

What it isn't: not a stimulant, not a hormone, not a protein. Not banned in any sport. Doesn't make you bulky.

Formulated supplementary sports food. Not suitable for children under 15 years of age or pregnant women: should only be used under medical or dietetic supervision. This food is not a sole source of nutrition and should be consumed in conjunction with a nutritious diet and an appropriate physical training or exercise program.
