The core five, and why the list is short
Sports nutrition rewards ruthlessness. Protein to a daily target does more than everything else combined; creatine monohydrate is the best-evidenced legal performance supplement in existence for repeated high-intensity efforts; and then comes the mineral most training diets quietly under-run. Magnesium's authorised claims read like a training brief — normal muscle function, normal protein synthesis, reduction of tiredness and fatigue, electrolyte balance, normal energy-yielding metabolism — and sweat-heavy volume raises demand. The form question decides whether you keep taking it: glycinate is the gentle chelate, and Futuro Labs Magnesium Glycinate delivers 300mg elemental per serving in delayed-release vegan capsules, £19.99 across a 90-day block. Cramps and restless legs are the classic tell — our cramps guide covers that lane.

The supporting layers
Vitamin D is non-negotiable for UK winters — government advice, immune and muscle-relevant claims, pennies a day. Omega 3 is base-diet support most training plates under-supply; Futuro Labs Omega 3 states its EPA and DHA per 1000mg capsule at £14.99, with the authorised heart claim anchored at 250mg combined daily. Sea moss earns the honest slot beneath all of it — background iodine (normal energy-yielding metabolism) and trace minerals for £9.99 across 60 days, and nothing more, exactly as our sea moss athletes guide frames it. On antioxidants, moderation beats enthusiasm: some research suggests mega-dosing around sessions can blunt the adaptation you trained for — keep doses moderate and away from the workout window.

Frequently asked questions
What are the best supplements for athletes in the UK?
The evidence-dense core is short: protein to daily targets, creatine monohydrate for repeated high-intensity work, magnesium for its authorised muscle-function and fatigue-reduction claims, vitamin D through the UK winter, and omega 3 as base-diet support. Futuro Labs covers the mineral and fatty-acid layers — Magnesium Glycinate at £19.99 for 90 days and Omega 3 at £14.99.
Why magnesium for training?
Because it holds the claims training cares about: normal muscle function, normal protein synthesis, reduction of tiredness and fatigue, electrolyte balance and normal energy-yielding metabolism — and because sweat and volume push demand up. Glycinate is the form that survives daily use without digestive drama; Futuro Labs Magnesium Glycinate delivers 300mg elemental per serving.
Do athletes need antioxidant supplements?
Carefully, if at all: some research suggests mega-dose antioxidants around sessions can blunt training adaptation, since oxidative stress is part of the adaptation signal. Food-first antioxidants, moderate doses away from the training window if you supplement, and treat sea moss as background minerals rather than a recovery product — our sea moss athletes guide covers the honest version.
