NeoLife Vitamin D

 Almost all vitamin D sold is derived from lanolin from lamb's wool. NeoLife vitamin D is from lichen and mushroom, a food source. The Current intake recommendations for vitamin D in adults under the age of 70 years is 600 IU per day (15 micrograms). Over the age of 70 years, recommendations increase to 800 IU per day (20 micrograms). The NeoLife product is manufactured to conform to general recommendations. In some cases much more vitamin D may be needed, but excess vitamin D can result in calcification of soft tissues.
