Magnesium citrate (powder)

Price at partner

Magnesium citrate — the best-absorbed form. Tops up what a long race drained.

What problem it solves

Magnesium lost in sweat in the heat — a deficit shows up as night cramps and slower recovery.

Dose and timing

1 scoop (≈ 300 mg of magnesium) in the evening, 1–3 days after the ultra. Don't take it with milk or yoghurt (calcium blocks absorption).

Pack size

200 g (60 servings)
