cholecalciferol

There are two kinds of vitamin D. D3, cholecalciferol, is the one you want to take. Also, like other posters have suggested, try going to the gym.

Yep, around here it's mostly the early afternoon hours during summer months that the UV levels even rise above the threshold of triggering cholecalciferol synthesis. For many people the summer vacation is pretty much the only time of the year that they have a chance to synthetize vitamin D on their own.

V=XAQ_Ef-OqrI India's death rate has been much lower than the US. Part of this is because they're already doing widespread cholecalciferol roll-out. If cholecalciferol is not on 2021's CDCs/FDA/AMA number one recommendation list for pre-Covid control, I will have considered the AMA a complete and utter failure in the united states.

> Calcifediol becomes active more quickly than cholecalciferol, enough so that if I were in the business of defending the Spanish study I might argue that it takes a few weeks for cholecalciferol to work, so giving it to someone who will already be dead or recovered by then is meaningless. Yes, this is one possible conclusion of these experiments.
