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
- What does L-carnitine do?
- L-carnitine is involved in fatty acid transport into mitochondria for energy production. Supplementation research is mixed — most evidence suggests modest effects on endurance performance and fat oxidation, with limited fat-loss benefit in healthy adults.
- Why a liquid format?
- Faster to take than swallowing tablets, no taste issues with the liquid versus an unflavoured powder. Trade-off is usually higher cost per serving.
- Where can I buy it?
- Amazon UK at £45 is the listed retailer.
- Is it Informed Sport tested?
- Yes — every batch screened against the WADA banned-substance list.
- How does this compare to L-carnitine capsules?
- Same active ingredient; the liquid is faster to take. Choose by format preference and per-serving cost (typically the liquid is more expensive per gram of L-carnitine).
