I use to get any brand of gel D3, but I went to a nutritionist for a few appointments and she recommended Jarrow Brand. Honestly, I'm not sure if it is necessary, but I've always heard very good things about this brand and my health has been so complicated of late, for now I'm getting the Jarrow Brand.

I know there are certifications for vitamins that you can look for on the label.

Years ago I was shocked when Dr Oz had a scientist on the show who said that he tested many, many fish oil brands and only found two (maybe three) to be pure as well as accurate in their labeling. One was Life Extension. It got me thinking...in many cases, not all vitamins are the same.

Have you had your vitamin D tested? No doubt one of the most important vitamins to keep optimized. You might need more; hard to say. Perhaps this is what you feel. ???? If you haven't done so already, consider talking with your doctor about testing your D levels.
