Tan your mushrooms, not your skin

Importance of Vitamin D to the Australian diet

Did you know almost one-third of Austrlians are Vitamin D deficient?

Enough sunlight on our skin should provide, for most of us, the natural catalyst for developing Vitamin D in our bodies. Yet the prevalence of skin cancer in Australia, means people do not get enough sunlight on their skin. We have become very good at Slip, Slop, Slap, and with good reason, however, this means that more than almost a third of us are deficient in Vitamin D. Thus, the need to supplement Vitamin D through our diet. 

Hi-D provides the ideal supplement for those who prefer a safe, whole food, plant based, clean alternative of Vitamin D.

Vitamin D2 and D3

Vitamin D2 is plant based and most D3 is animal based (sheep wool - lanolin). Vitamin D2 (ergocalciferol) and Vitamin D3 (cholecalciferol) are both effective in raising blood levels of vitamin D.

Recent studies suggest that when it comes to bioavailability and absorption, both forms of vitamin D are relatively similar. The body efficiently absorbs and utilises both forms. Vitamin D2 is a valuable option, particularly for those with specific dietary preferences or restrictions. Ultimately, both forms support the body’s needs for vitamin D, promoting bone health, immune function, and overall well-being.

Whole Food vs Extracts

Extraction in chemistry is a separation process consisting of the separation of a substance from a matrix.

The issue with extraction is they most often use chemicals in the extraction process which no longer makes something a whole food and has negative effects on the environment.

The benefit of a whole food product is that it retains all of the nutrients and goodness. When we eat whole food, we're not consuming single nutrients, but rather a range of vitamins, minerals, ensymes and proteins that synergistically work in our bodies.

There are many so called "whole food" products out on the market, but look closely at the use of extracts as they may be present in many products.

We are proud that at Hi-D, our products are 100% whole food and free from all chemical extractions.
