PNI Supplements have proven once again they don’t run with the crowd as through experience and innovation they have gone beyond the simple protein powder, weight gainer, creatine, etc. they have expanded their product line with a holistic approach in which they have started with an improved dosage of Vitamin D3.
Vitamin D is an essential vitamin which is often referred to as the sunlight vitamin as it is the major natural source of the nutrient and is synthesized in the skin upon exposure to the radiation from the sun but it is also found naturally in fish and eggs as well as being added to dairy products. Vitamin D is a fat soluble nutrient and one of 24 critical nutrients for basic human survival.
The way in which the human body produces vitamin D is from cholesterol providing you have been exposed to the sun long enough to accumulate an adequate amount of UV light. This is often difficult depending upon your geographical location as there is only a sufficient amount of UV light coming from the sun all year round near the earths equator.
