Topping up your vitamin D tank
Dr Davis suggests it may take up to 3yrs to be sure your vitamin D reserves are fully restored at intakes around 10,000iu/daily.
With the 50,000iu capsules you have bought that works out at ONE capsule every 5 days.

A rule of thumb (guesswork) is to take 1000iu/daily for each 25lbs you weigh.
so just over 7000iu/daily MAY be sufficient (for someone living in the USA and getting some sunshine when possible) This would mean one 50,000capsule each week.
If you find that easier (just having SUNDAY your vitamin D day) than trying to remember every 5th day it MAY be sufficient.
If you want to stick with the 10,000iu/daily average but only take the capsules ONE day each week so it's easier to remember you could ALTERNATE one 50,000iu week one and 2 x 50,000iu week two and so on so every fortnight you took 3 x 50,000iu total 150,000iu over 14 days = just over 10,000iu/daily.
It would be worth asking for another 25(OH)D test in 6 months to see how it works out in practice.

do be aware that every responds differently and what suits most people may not suit you.


Also don't forget that vitamin D3 works in conjunction with magnesium and omega 3 and these also all affect mood. Similarly getting outside into bright sunlight not only creates vitamin D3 it also resets your circadian rhythm. This enables your body to secrete more MELATONIN, another anti inflammatory, anti oxidant that works in the brain and protects mitochondria. It's roles are as many and as varied as Vitamin D3, omega 3 and magnesium and should not be overlooked.
