I just bought a used tanning bed for my wife for her Bday/Christmas present. I'll also be buying a set of nice UVB bulbs. Currently I don't take much over the summer, especially if I have been getting good sun exposure. I'm shirt off guy, if it's appropriate for me to have my shirt off and it's warm enough, I'm taking my shirt off.
This fall I plan on getting the ngl blood test though and then mid winter, I'll take it again with the tanning bed exposure. If I'm good I'll probably just keep the tanning up and skip the supplementation. It's not like the D is expensive, but if I can have my skin make it, I feel it's even better.
Through the past few winters I have been doing 5,000 iu of D3
