Strenuous exercise is known to affect the immune system by suppressing it 3-72 hours after exercise. This can lead to an increase in the incidence of upper respiratory tract infections, affecting the athletes’ health and ability to train. Excessive vitamin intake can inhibit the exercise response. SiS Immune is formulated at a level that supports the athlete’s health without compromising the benefits of exercise. An effervescent tablet that dissolves easily in water is a very practical approach to supporting the immune system after exercise. Vitamin C (200mg) and iron (2.5mg) additionally contribute to maintaining the normal function of the immune system during and after intense physical training.
Directions for use

Add one Immune tablet to 500ml of water and let it dissolve. Consume the finished drink within 24 hours. Consume 1 tablet per day in addition to a balanced diet and a healthy lifestyle.


Why should I take this?
Vitamin C and Iron are known to contribute to the maintenance of the normal function of the immune system during and after intense physical exercise.

How is this different to other Vitamin C tabs?
SiS Immune contains 200mg of vitamin C and 2.5mg of Iron, which along with a normal diet provides the correct amount to support immune function post-exercise. This is preferred over tabs containing well over the RDA of antioxidant vitamins, which can suppress your response to training.

Wouldn’t I be better off taking a multivitamin?
SiS Immune also contains key electrolytes, which can aid hydration after exercise as well as providing what the body needs to support immune function. A multivitamin cannot do this, and may contain elements that your body doesn’t need if you are not deficient in them.

What is the difference between this and SiS GO Hydro?
SiS Immune should be taken post exercise to support and maintain immune function while rehydrating. SiS GO Hydro should be taken during exercise to maintain hydration only, when energy is not needed.

Can I mix this with GO Electrolyte or GO Hydro to get all the benefits?
No, this would provide too much sodium, beyond the optimum levels.
