I suffer from mood swings along with a low baseline of depression, and a friend suggested Vit. D supplements. It is true that I had avoided the sun for 4 summers straight while on a moderate dose of lithium (NO heat/sun tolerance), so taking vit. D seemed that it might help with that everyday lack of energy/ low mood. It did! I started taking 2 of these tablets per day about a month ago, and still I do not go a day without taking at least one. Since my mood has improved going OFF of several meds (including lithium), I'm now down to about 1 a day - unless my mood starts to dip. I think this will be a life-saver in the winter. Esp. since I'm mildly lactose intolerant and do not down a whole lot of fortified milk. Have not experienced any interactions with the anti-depressant or anti-anxiety meds.

it's 'fine' i just find it hard to swallow.

My doctor tested my vitamin D level and found it was low. She suggested that I start taking vitamin D3 supplements. They're not that easy to find (vs. the regular vitamin D pills) so was happy to see them here. I can't speak to the efficacy of them. I guess I'll only find that out when I visit my doctor again and she checks my level. So this rating is based on price and ease of swallowing, which I find both to be great.

Great for people in northern climates that don't see the sun for long periods in the winter.

They're on the larger side of a tablet and not coated so they're a little harder to swallow than some. But for the price, since I have to take them every day, they're worth it!
