Not called 'Best D3' for nothing!

Why take 4 a day when you can take one! This is more economical too! If you can't get 1/2-hour of good sun every day (without burning!), this has to be the next best thing. And it's in a decent carrier oil (Xtra-Virgin Olive).

Perked me up but have to remember to eat fat with the tablet

Perked me up but have to remember to eat fat (egg, coconut oil, butter etc) with the tablet, or I end up sick in the stomach. Really helped reduce feelings of dread and some depressive feelings.

I use this D3 along with K2 and it's finally getting my levels up. Easy to swallow, no aftertaste or burps. I'm reordering.
