SiS Immune

Science In Sport Immune Effervescent Tablets

A daily-use immune tablets formula built specifically for athletes — runners, lifters, cyclists, and team-sport players — whose training volume creates the kind of immune suppression that recreational supplements aren't designed to handle. Ideal during heavy training blocks, race-prep weeks, travel, and the post-race window when upper respiratory tract infections are statistically most likely to hit.

What makes SiS Immune worth choosing over the average immune booster drink at the supermarket comes down to dosing intelligence. Each effervescent tablet provides 200mg of vitamin C (250% NRV) plus 2.5mg of iron and sodium for hydration support — a deliberate, athlete-specific formulation. The dosing is critical: research has shown that excessive antioxidant vitamin intake (particularly mega-doses of C and E) can actually blunt the training adaptation response, so the formula is pitched at a level that supports immune function during the well-documented 3–72 hour post-training immune suppression window without compromising the gains you're training for. That's a meaningful distinction from generic 1000mg+ vitamin C products that treat "more" as automatically better. The effervescent format also pre-dissolves the nutrients before they hit your stomach, improving uptake and turning recovery hydration into a single drinking action.

Science In Sport is a UK-based brand publicly listed on the London Stock Exchange (AIM: SIS) and manufactured to GMP standards. SiS Immune is Informed-Sport registered with batch-level testing for WADA-banned substances, making it a credible choice for tested-pool athletes. The brand is the official supplier to multiple WorldTour cycling teams, Olympic federations, and Premier League clubs.

• 200mg vitamin C (250% NRV) per tablet — calibrated to support immune function during the 3–72 hour post-training suppression window
• 2.5mg iron (18% NRV) to support normal immune system function and oxygen transport
• Added sodium to support post-training rehydration alongside the immune dose
• 20 effervescent tablets per pack, vegan-friendly — practical, allergen-friendly immune up tablet option for athletes
• Informed-Sport registered — credible immune vitamin tablets for tested-pool competitors

Pair it with a daily multivitamin or recovery shake from our vitamins and supplements range to round out a complete training stack.

Drop one tablet into a glass of water (around 200ml), wait for it to fully dissolve, and drink. Take post-training, particularly during heavy training blocks, race-prep weeks, periods of travel, or whenever immune support is a priority. Use consistently rather than only when symptoms appear — the formula is designed for daily preventative support during high training load. Store the tube tightly sealed in a cool, dry place to keep tablets dry..
