So my lab results are back and this is what Dr. Pellegrino recommended: Lyme: negative EBV: showed past exposure but no current Vit. D: normal magnesium: lowest end of normal B12: lowest end of normal IGF(immune growth factor 1): lowest end of normal Based on the "low end of normal" results, he recommends taking "FibroCare" which contains magnesium (among other things), colostrum supplements (to increase my immunity), and Vit. B12 tablets that go under your tongue. My question is: if these are all within "normal" range, do I really need to supplement? Does anyone else supplement who has tested into "low-normal" range? Also, the FibroCare has magnesium, manganese, B1, B6, C, and malic acid. Would this be preferable over just a straight magnesium supplement? The reason I'm asking is because Dr. Pellegrino sells these supplements at his office (and I'm NOT saying he is only in the business of making money however he can), but it still begs the question "if my levels are in the normal range, should I really supplement"?? Thanks for any and all advice!
