Why this certification matters

- NSF Certified for Sport is designed for athletes in tested sports; each lot is tested for substances banned by major sports organisations.
Frequently asked questions
- How does PH 500 differ from PH 1500?
- Both are PF&H hydration tablets named by sodium concentration per litre. PH 500 is the low-sodium variant (500 mg/L); PH 1500 is the high-sodium variant (1500 mg/L). Choose based on individual sweat-sodium loss.
- Who uses a low-sodium hydration tablet?
- Athletes with lower sweat-sodium loss, or for situations where you're hydrating without heavy sweating (e.g. flights, daily hydration). PF&H's underlying positioning is around individualised sweat testing to match sodium intake to sweat loss.
- Where can I buy it?
- Amazon UK at £8.99 is the listed retailer.
- Why is the brand 'Precision Hydration Ltd.' rather than 'Precision Fuel & Hydration'?
- Precision Hydration Ltd. is the brand's earlier name. They rebranded to Precision Fuel & Hydration when expanding into fuelling products. Older NSF-certified SKUs still carry the previous branding.
- Is NSF as strong as Informed Sport?
- Both test against the WADA banned-substance list. NSF Certified for Sport is the US-dominant cert (used by the NFL, MLB, MLS, PGA); Informed Sport is UK/European-dominant. Either gives tested-athlete assurance.
