Hi folks . Can give me some ideas on tweaking my supplements? I was up most of last night with muscle cramps, and the intensive stretching I did for a few months to prevent cramping has permanently damaged my sacroiliac joint. So, no more of that. I have been searching and reading old threads for what might help, but so far have not found any ideas. I am currently taking, daily: 2mcg B12 (Yes, only that, for the past 9 months or so. I am eager to increase this as soon as I can get the cramping under control. Each time I try, cramps get worse.) 1.5mg folate (half folapro, half folinic -- really I take 7mg once every 5 days) Potassium: In addition to a fruit and veg-heavy diet, I get 3000mg in supplemental foods, daily -- carrot or coconut juice, dried fruits, and potatoes. I do feel it if I eat less. iron 76-94mg (I have IDA) calcium (was 1000mg, have decreased to 333 this week but that may be making cramps worse) magnesium 600mg oral + about 1000 topical selenium 100mcg vit K 50mcg vit D 10,000-15,000iu, plus about the same from uv light. ( I am deficient.) vit C 0-3,000mg vit A, gamma-heavy blend, 400mg copper 0.66mg (I would like to take more -- any tips on avoiding vomiting?) sunflower lecithin 3,800mg fish oil and evening primrose oil. I was taking a lot of zinc until 3 months ago, when I realised it was way too much so I stopped it and added in the calcium. Is it time to add it back again? I have very limited access to testing. There is not a lab in my area, and it usually takes several months to arrange a test, though sometimes I get lucky and it's only a couple weeks. The lab does not send out tests, so they can't do the very unusual ones -- just in house stuff. So I have to choose my supps based on other people's experience and trial and error. Should I try some other B vitamins? What works for you, and in what dosages? Is there a write-up somewhere about the different 'add later' methylation supps? I keep seeing these references to starting with the things I am taking, and adding in more things later. Have I reached that stage? I am currently doing a yearlong program of food allergy testing, so supps that are corn-derived like D ribose might need to wait a couple of months. I can speed that up, though, if someone thinks one of them might be the source of my problem. Sleep and injury prevention are paramount! Thank you so much for your help! Even this tiny amount of B12 has done wonders for me, and I sure would like to be able to increase it.
