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
- Why a liquid magnesium versus a tablet?
- Liquid format is faster to take and may absorb slightly faster than a tablet. The trade-off is a stronger taste and a usually higher cost per serving.
- Where is it sold?
- Amazon UK at £30 is the listed retailer — likely a multi-pack of single-shot vials.
- What form of magnesium is in it?
- Check the live product label — Powerbar publishes the magnesium source on the bottle.
- Is it Informed Sport tested?
- Yes — every batch screened against the WADA banned-substance list.
- When should I take it?
- Magnesium can be taken pre-bed (some users report sleep benefits) or post-training. There's no strict timing requirement.
