1,890mg antiviral botanical blend. Zinc at 500% NRV. Vitamin C at 200% NRV. Boost and protect.
Intense training suppresses immune function. The same physiological stress that drives adaptation temporarily weakens the defences that keep you healthy. Most athletes ignore this — and lose training days to illness.
Immune Booster® was built for athletes who can't afford to be ill. 1,890mg Bio-Imuno Blend — Elderberry Extract, Echinacea Purpurea Root, Liquorice Root, Astragalus Root — four of the most studied botanicals in immune medicine at a meaningful dose.
Zinc at 500% NRV and Vitamin C at 200% NRV address the micronutrient dimension — high-strength immune support that training athletes genuinely need.
Suitable for vegans. 90 capsules.
