I have a couple questions for any doctors out there.
How many times a year should one check his vitamin levels?
I live in Paris, and during the winter months we don't get that much sunlight. My doctor gave me a prescription for vitamin D3 (100,000 IU vial, once a month, for three months). Is this a good dose for the year (provided you get adequate sunlight during the summer months)? How long does vitamin D3 stay in the body until it uses/flushes excess out? Are you better off taking a high dose like this for 3 months, or adopting a more slow and steady method (i.e. supplementing daily).
- baccheion 6y agoCan you get D3 from a store? Prescriptions are usually vitamin D2. 20,000 IU or 50,000 IU D3 1x/week is a great amount. Or you could try taking a lesser/proportional amount each day. You could also get one of those sun/S.A.D. lamps or red light devices to increase topically.
- lprd 6y agoJust checked the box again and it says "cholecalciferol (vitamin D3) 100,000 IU". I believe the prescription is required due to the dosage (100,000 IUs is pretty high). I could definitely get some D3 from the store, but I am curious if taking a prescription dosage once a month yields the same result as a lower daily dose.
- raverbashing 6y agoIt is fat-soluble so theoretically it should be ok (based on my limited knowledge and the fact that it's a prescription product) (I'm not sure those are the vials I'm thinking about, I remember ones that were Vit E maybe of a very oily liquid that I had to take once - not bad, but definitely weird)
- baccheion 6y agoOnce a month is too infrequent, but it'll work fine. 1x/week is better. 1x/day is best. Some benefits are missing versus daily dosing, but the main things are still in play.
