Vitamin D-3 5000 IU
Bone and immune support. This is a textbook hero product. 5000 IU is the standard clinical dose for effectively raising blood levels. It uses the superior D3 form instead of the less effective D2 version.
9.5/10
EXCEPTIONALD3 at 5000 IU (125mcg) exceeds optimal dose of 4000 IU while staying well under the 10000 IU upper limit. This is the ideal corrective and maintenance dose for the majority of adults. Olive oil base ensures fat-soluble absorption. Clean softgel with minimal excipients. Vitamin D3 has rock-solid evidence (score 10). At NOW Foods pricing, this is one of the best supplement values available anywhere.
