Most people don’t realise how important zinc is for our overall health and wellbeing. Zinc mobilises the 300 hormones and enzymes containing zinc that play an important role in your body’s defence by supporting healthy immune system function.

A chewable tablet from Greal®, Zn Sentinel contains 10mg of chelated zinc with premium, natural sugar substitutes and a natural flavour. Zn Sentinel supports your healthy immune system function, skin and oral health, and both men’s and women’s reproductive system health.

Struggling with low immunity? Feel your skin is unhealthy? Make Zn Sentinel a part of your daily routine and notice the difference.
