From: My Thoughts On Supplements
Before I knew to gluten free my life was saved by supplements. Special tests determined exactly which nutrients were needed for me. Interestingly enough, magnesium, potassium, vitamin B, were among them. They were doctor recommended supplements and a high quality product designed for max absorption.
By life saved I mean: My orthostatic blood pressure had an unhealthy curve. When I rose up after lying down the blood pressure would plummet and stay down. My blood pressure was 180/115 when resting. The supplements brought the orthostatic blood pressure to a normal curve. This meant it started low, went up as I stood, and recovered after a minute or two. Over time, my resting blood pressure came down to 110/70. I wouldn't recommend just supplements, and not going gluten free, but high- quality- supplements, carefully, selected can do wonders.
