D-3 by Source Naturals makes me sleepy, so...

have to take at bedtime. Also helps with joint stiffness next day. Another sublingual brand of 10,000 IU by Superior Sources does not seem to have any effect on me.

I see that some folks get energized with D3. So what is the difference? Am currently trying to figure out which brand to go with next.Thanks.

Also use Carlson's CLO, but only about a TBSP per day. Tweet
