Immune Support

Products chosen around immune support — colostrum, vitamin C, zinc, vitamin D3 with K2, NAC and selenium — from ARMRA, Solgar, Quicksilver Scientific, Blueprint and Designs for Health.

Colostrum, vitamin C, zinc, vitamin D3 with K2, NAC and selenium — from ARMRA, Solgar, Quicksilver Scientific, Blueprint and Designs for Health. One of the larger need pages, and one where doses vary enormously between brands.

Vitamin D is the clearest example: the products here run from modest daily amounts to high-dose weekly ones, and the only way to know which you want is a blood test rather than a product page. Every label states its micrograms and its international units.
