How we work
Identity, purity and a heavy metals panel covering arsenic, cadmium, lead and mercury — issued per batch, not per product. See what that means.
Testing is carried out by analytical laboratories independent of the supplier. How that is arranged.
Order by 12 noon, Monday to Friday, for same-day dispatch. Free UK delivery over £75, £4.99 tracked below that. Delivery details.
