NatureWise Vitamin D3 2000iu (50 mcg) 90-Day Supply for Immune Support

Our verdict

NatureWise Vitamin D3 2000iu (50 mcg) 90-Day Supply for Immune Support works out to $0.10 per serving of vitamin d3, at 2000IU per serving in softgel form. That puts it below the median of the 290 vitamin d3 products we can price per dose, where the typical serving costs $0.11, a Value Index of 1.1 where the median product is 1.0. One container lasts 90 days at the label dose of 1 serving a day, about $3.00 a month. We could not verify a third-party certification for NatureWise in a public registry.
