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's in it beyond BCAAs?
- Per serving: 5 g BCAAs (2:1:1), three electrolytes (sodium, chloride, magnesium), vitamin C, zinc, rhodiola rosea extract and 250 mg of Wellmune. The 'Sustain' side is the electrolyte and recovery support.
- How is the Elite Series different from regular Gold Standard BCAA?
- The Elite Series carries Informed Sport — batch-by-batch screening against the WADA banned list, the tier UK and European tested athletes look for. It's sold direct from ON rather than across third-party retailers.
- What is Wellmune?
- Wellmune is a branded baker's-yeast beta-glucan ingredient marketed for immune support. This product includes 250 mg per serving; we don't make health claims for it beyond what's on the label.
- Is shipping included in the £35 ON direct price?
- No — Optimum Nutrition charges delivery separately unless you hit a free-shipping threshold or use a promo code. Check the basket total before ordering.
- Where can I buy it in the UK?
- We track one UK listing: Optimum Nutrition direct at £35, with 3,500 reviews averaging 5.0/5. Confirm the live price and serving count before purchase.
