Why this certification matters
- Informed Sport
- Informed Sport certification is especially relevant for athletes in tested sports because products are batch-tested for substances prohibited in sport.
Frequently asked questions
- Is Maxi Nutrition the same as MaxiMuscle?
- Maxi Nutrition is the modern UK brand that grew out of the MaxiMuscle heritage. Different ownership and product line today, but the lineage is well known in UK sports nutrition.
- Why does a vitamin D3 carry Informed Sport?
- Tested athletes often want banned-substance assurance even on baseline vitamins, because contamination can sit anywhere in the supply chain. Informed Sport tests each batch before release.
- Where can I buy Maxi Nutrition Vitamin D3?
- Amazon UK at £7.99 is the listed retailer. That sits at the lower end of the Informed Sport-certified D3 market.
- How does it compare to non-certified D3?
- The active ingredient is the same vitamin D3 (cholecalciferol). The difference is per-batch banned-substance testing, which matters mostly for tested athletes. Non-certified D3 is widely available and usually cheaper.
- When should I take vitamin D3?
- D3 is fat-soluble, so it absorbs better with a meal containing some fat. Time of day doesn't materially affect absorption.
