Bests & Worsts Reviews from Amazon

I used to go to a tanning booth once a month or so in the winter when I'd start feeling tired. I would notice more energy the day or two after. Vitamin D3 supplements did not seem to do anything, so I suspected I was not absorbing the capsules properly. Trying this liquid was an experiment I really did not expect to work. What a surprise that I could feel the same effect as after tanning! After experimenting, I found that 2 drops a day work for me and do not exceed the safe amount. Just be careful that you know how much is too much, since it's easy to squeeze too much with a dropper. As long as you know what you are doing the dropper is best. I seldom write reviews, but hope if more people find out this brand works, it will be around for a while to continue to order!
