For me personally, my blood pressure went from slightly elevated to completely healthy by doing the diet/protocol, so it improved over time for me. I think it can be tied to candida and general health in my opinion.
A and D should be taken together, the only unfortunate thing about them is that we don’t know what the correct ratio of vitamin A to D should be (no scientist does), so in my opinion, its best to get sources of vitamins A and D that come from natural sources. A good natural source of vitamin A and D is fermented cod liver oil, which has a number of benefits. One of its greatest benefits is that it reduces inflammation.
