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
- Who is behind fourfive nutrition?
- The brand was set up in 2018 by George Kruis and Dom Day, both former professional rugby players who built fourfive around products they wanted as tested athletes. The range is made in the UK.
- What is in the Performance Blend besides cordyceps?
- Alongside cordyceps mushroom extract, the capsules add CoQ10 and vitamins C, B6 and B12. Several B vitamins contribute to normal energy-yielding metabolism and the reduction of tiredness.
- What format is it?
- It is a capsule, so there is no mushroom powder to mix into drinks — a fixed dose per capsule taken daily.
- Is it suitable for drug-tested athletes?
- Yes. It carries Informed Sport certification, meaning every batch is independently screened against the WADA banned-substances list — the reassurance the founders built the brand around.
