SiS - Science in Sport

Science in Sport (SiS) has been a cornerstone of sports nutrition since its founding in 1992. With a strong scientific foundation, the brand develops energy gels, powders, hydration mixes, bars, and recovery formulas used by professional athletes, national teams, and sports performance research programs. Their core mission is to support endurance, recovery and hydration in a way that is both effective and trusted.

What sets SiS apart is its rigorous quality assurance: every product is certified by Informed‑Sport (a third‑party anti‑doping lab), and each batch is tested to ensure purity and absence of banned substances. They work closely with elite athletes and teams to validate formulas in real‑world conditions, not just in labs.

For biohackers and longevity‑oriented individuals, SiS offers more than raw fuel. Their products help optimize energy during training, refine hydration strategies to avoid metabolic stress, and aid recovery to reduce inflammation and support repair. Their well‑researched carbohydrate formulations (e.g. gels and powders) are designed to sustain performance over long durations, which is a key factor in preserving healthspan in high‑demand lifestyles.
