That is something I was not aware of or even knew existed I appreciate the knowledge and feedback brother. Thank you for the tips !Good morning,
try to buy a brand that offers vitamin d3 in an oil and nothing more (no glycine, no water etc...).
Put in a tablespoon with olive oil and add your drops of vitamin D3 EVERYTIME and tell me if your level are not better when your get your blood work.
K2 help but lipids help also a lot for vitamine D
