Desiree Estelle Lotz - CEO and Founder of Sunshine Vitamins and Instant CalMag-C

Meet Desiree

CEO & Founder of Sunshine Vitamins and Instant CalMag-C

Trained as a detox specialist and having helped thousands of people as a nutritionist, I understand how important it is to have the utmost quality supplements in assisting the body with detoxification and proper function. 

I have always had the purpose of helping others, and genuinely believe that healthy living is happy living.


I created Instant CalMag-C while still living in South Africa when I observed how miraculous calcium and magnesium can be for the body in everyday life as a basic aid in calming the nerves, soothing muscles, improving sleep, and minimizing stress. Sunshine Vitamins was born in Johannesburg in 1995 and provided a full range of high quality nutritional supplements throughout South Africa.

In 2003 I came to visit my daughter in America and loved the country so much I decided to make it my home, bringing with me Sunshine Vitamin's flagship product, Instant CalMag-C.  

I ensure that our product is made of the best quality calcium and magnesium and that Instant CalMag-C meets the high standards that we know our customers deserve.  

Welcome to the Instant CalMag-C website. I invite you to try Instant CalMag-C for your entire family and look forward to hearing from you with your personal experience.

"Our goal is a drug-free, stress-free and healthy world.

It starts with basic good nutrition and top quality supplementation to compensate for any shortfall in nutrition."
