Low Vitamin D puts you at higher risk for various cancers, including breast, and uterine cancer, as well as low bone density. Thus, I recommend a supplement of 4000-6000 IU of Vitamin D3 daily. Almost any OTC supplement will do for Vitamin D3 - some brands include Kirkland Signature (Costco) Extra Strength D3 2000 IU, Member’s Mark (Walmart) Vitamin D-3 2000 IU, Garden of Life mykind Organics Vegan D3 2000 IU, Nature Made Vitamin D3 2000 IU, Vitacost Vitamin D3 5000IU, Source Naturals Vitamin D3 2000IU (liquid), - I also recommend checking your Vitamin D levels with labs at least once a year.
