Immune Effervescent Tablet

What Our Gearhead® Experts Are Saying:

"I started keeping the Immune Effervescent Tablets in my kit during heavy training blocks when I know my immune system takes a hit, and the combination of 200mg of Vitamin C with iron in a low-calorie hydration format makes it easy to stay on top of without adding another big supplement to the routine. It dissolves clean, tastes good, and fits naturally into my pre or post-workout hydration without any fuss."

Hard training and big days outside push the body in all the right ways, but they also put real demands on the immune system that are easy to overlook until you are already run down. Science in Sport's Immune Effervescent Tablet is designed to fill that gap simply and effectively, delivering 200mg of Vitamin C and 2.5mg of Iron in a low-calorie effervescent format that dissolves directly into your water bottle. Vitamin C contributes to the normal function of the immune system during and after intense exercise, while Iron supports normal immune function and helps reduce fatigue, making this a practical daily addition during periods of heavy training or back-to-back adventures.

The effervescent format keeps the experience easy and the calorie count negligible at just 8kcal per serving, so it fits naturally into any hydration routine without disrupting nutrition targets. Inulin adds a prebiotic fiber component to support gut health alongside the primary immune-focused vitamins and minerals. At its core this is a no-friction solution from a brand that has spent decades developing nutrition products for serious athletes, designed to keep you healthy, recovered, and ready to show up for the next session at full capacity.
