what would be the current best practices for an individual looking to optimize their fat soluble vitamin intake?
what are the best blood tests?
would you start with knowing d levels and then tweak a & k based on d? i hear an a:d ratio of anywhere from 4:1 to 10:1 is ideal regarding intake per day.
(i supplement with 4-6k iu d3/day each morning when i wake, although i am very susceptible to s.a.d. and always feel better in bright, sunny, warmer climates which i don't currenlt live in. an example: i felt healthiest in sydney australia in the summer, worst in connecticut and portland, oregon. i now live in san francisco.)
how does one "know" when they are at the right level for themselves?
are there "perfect" d, a, and/or k ranges for all/most humans?
I go by how I feel.
I do get my D tested once a year and simply make sure I eat a variety of animal foods so I get a reasonable supply of A & K (liver and pastured butter do the trick!)
I also supplement 200-400 mg of Magnesium citrate.
Ovethinking just raises my cortisol, so I don't sweat the details as long as my health is good.
Haven't been sick in over 2 years!
I keep my D level around 80 ng/ml to kep my asthma away.
