After 21 years, TenaZ is still changing people’s lives, here is Gerrit and Hannie Herbst’s story.

TenaZ was founded in 2003 by Sanet Muller, who is also the CEO of the company.

Sanet struggled with her weight for years and decided to formulate a product that promotes a balanced holistic lifestyle.

In collaboration with Dr Trevor Bailey, Sanet has already done 18 years of development and testing on Tenaz’s products.

TenaZ restores chemical, hormonal, and nutrient imbalances that cause unexplained weight and sometimes health problems.

With TenaZ’s products, they bring “mind, body & soul” together so that you can achieve your dream weight and goal.

Sanet and her team will support you in your weight loss journey so that you not only lose weight but also live a healthier life.

All TenaZ products are:

Pure Cell food

Free from Stimulants

And is not addictive

It is TenaZ’s policy not to treat children under 16, as pregnant or breastfeeding women. We do not claim to cure any medical conditions in fat control and lean muscle mass preservation.
