@motorhead - L-carnitine fumarate seems to be the one that works best for about 90% of the people doing this. However, my experience is that from time to time, the carnitine I need changes. Only one works well at a time but it can stop working suddenly and then you need a different one. I generally have kept 4 or so varieties oin small bottles and the one big bottle i s the current which might last a year or 5 or a month or 2 until having to try each one, one kind a day until finding the one that works. Also methylfolate can work great as Metafolin for a month or 5 years and sudden;y have to switch to Quatrefolic . I keep both on hand, These happen quickly.
It's me, not a mouse model that is diagnosed. I have had copper deficiency for 10 years, very difficult to get balanced out with zinc and iron and so on.L appears to restore some degree of homeostasis. Also during the worst deficiency I had liver damage, antibiotics causing more damage to liver while low on copper, nerve SACD "like" lesions and neurology damage and so on. Copper is involved in all sorts of ways. As the lithium TCR-Li built up over 5 years, the copper got more stable , my kidneys eGFR went from 59% to 86% as it grew more TCR-Li and the B12 serum half life went from 20 - 50 minutes to 24 hour pause then with maybe 12 hours serum halflife when 1 week went between MeCbl sublingual doses or injections.
So 13 months ago I had the most normal set of CBC tests I've ever had. Both me and my internist said how normal they look. 10 months ago my copper plunged from high end to low end of range, my testosterone went from low because of a prescription mess up to 4x what it should have been for the tapering testosterone. My hypokalemia required 50% increase in potassium to not have frequent gut paralysis. I had skin lesions indicating cell failure from lack of methylfolate or copper or ? The past ten months something has been growing hard and hot and it turned out to be prostate cancer with large jumps in PSA at 10 months, 7 months, 4 months and smaller increase 1 month ago. This is a;ll quite new to me and I'm sharing the information I have and hope somebody recognizes it and recognizes. The doctors all say must get it out quickly before metastasize occurs..
