I would add redlight or incandescent lights. When you get UV from the sun to get vitamin D, the red light component of the sun protects you from the damaging aspect of UV to some degree.The color temperature of 7500K suggests it has less red than... (more)

I think the answer is you should take the calcium and magnesium at the same time, and that the Vitamin D3 can be taken whenever. In fact, I think prescription mega dose vitamin D is given once/week. The brand of K2 I use is life extension k2... (more)

I have bought vitamin D3 drops and have been adding two drops to a plate of food before we eat it. Will it have the same effect if I add it to the whisked eggs and then cook the omelette or is the vitamin denatured by the cooking?

Agree with Firestorm. Since it is fat soluble, you can take it once a week, if that works better for you. Take them in the morning or afternoon with a fatty meal for optimal absorption--too close to bed & they may keep you up. I prefer... (more)

Sounds like a gimmick to me. D3 requires further processing by the body to be converted to the active form of Vitamin D in the body, so it doesn't seem likely that a quickly-absorbed sublingual dose would be all that effective. I'm sure it's... (more)

Vit K2 is not banned here in Canada, there is just a maximum strength that is allowed to be sold by Law, it's 60mcg or 100mcg. I buy Vit K2 @ 100mcg from my health food store regularly.
