Having studied the vitamin D3 pandemic that is killing millions of poeple world wide through lack of sunshine for the last ten years i regard myself as an expert on this subject.First of all this is not a vitamin,although it was thought to be a vitamin 40 years ago when discovered and misclassified.In fact it is actually a hormone that is naturally synthesised in your skin when exposed to sunlight.The average human body contains aprox 100 Trillion cells,each one of them has a VDR receptor asking for uv rays ie: sunshine.THEY ARE THERE FOR A REASON.We have come from evolution.Unfortunatley the ingested form ie:these softgels do are lacking in at least 12 biological benefits that you get from sunlight or better still the controlled environment of a sunbed tanning salon.
Even so they are very well versed and praised by the endemiologist and photobiologist in the research of cancer and all chronic illnesses.Not to be confused with vitamins.This is a hormone.As for the comments on some of the reviews it would appear that some people expect a kick up the ass as with certain substances.This is a serious subject and should only be commented on in such a damaging way by experts and not novices with no research behind their comments.
One very important thing about this hormone is that it can only work if your calcium levels are at 1400 mg.
So if you dont eat a lot of food with calcium in it then i suggest that you also take a supplement of around 600 mg daily.Please do not listen to the dermatolgy fraternity hell bent on demonising the sun so as to sell the multimillion pound industry of selling spf factors which is adding to the problem of cancer and all chronic illnesses.google this man proffessor micheal holick.
