Whether you are a 65 year old woman, a 20 year old man or an infant - Vitamin D3 is the clear winner. It is absorbed MUCH better, has a longer half life in the body and is more shelf-stable. Some researchers believe that vitamin D2 should no longer be used for supplementation or fortification of foods.
Due to the fact that as you get much older your vital system will be wearing out and be taking in less of the suplements from your daily food consumption. Meaning you will need to take more vitamins if any than an 18 year old to keep your body healthy.
