for a long time, i've been a big advocate of looking after the most important component in your system... you.
already very keen on the:
high doses of vitamin d3 (choelicalciferol ~ or however it gets spelled)
(i take 2-4 125microgram softgels of it a day, to make up for me being so far north, and so indoorsy, and so often nocturnal, which is 10,000 - 20,000 i.u, if you like that sort of seemingly arbritrary measurement of "international units"... dont let r.d.a of vitamin D scare you off taking this much D3, since the rda relates to D2, which is rather more toxic... but if you do think you need high levels of vitamin d (which if you live farther north than the meditaranean, you almost certainly do) you might want to build up to the 5000 iu first... i got horrendous headaches when i jumped in with both feet from no supplementation to 5000 iu.... though that coulda been caused by other factors. but again, dont freak out at the massive increase compared to the RDA for vitamin D... you make about 30,000 a day for each day of 15 minutes full body sun exposure, after 3 days of acclimatising to it. and if you live this far north, that never ever happens. heh.)
and more recently of:
double RDA of vitamin B12
(and a b vitamin complex ocassionally, as well as my regular 2700% rda of inositol for my raynauds condition)
.. had my first dose of 5-htp last night, and i feeeeel great.
great enough to jump up n do some tai chi n yoga after breakfast.
