Source Naturals Vitamin D-3 Liquid, 2 Fl Oz

I am amazed at how quickly it works, my energy level is almost back to normal, and the fact you can use it in a drink makes it easier to use. I was tired and sluggish throughout the day due to my medication, I would just doze off throughout the day but even though it has only been a week my naps are less and my sleeping habits have improved as well as I did have insomnia I now sleep all night rising at around 6 am and I'm okay with that. I feel well rested and happier.

Works as expected. Increased my blood vit D levels and improved my mood. They changed the formula, so it's not as high of dose per volume, but it still works fine.

So far it's been great. Love that it's liquid so I can put it in smoothies. Doesn't have alot of other ingredients.

Built-in eye dropper makes counting out daily dosage (10 drops) easy %26 efficient. Mild citrus flavor is not unpleasant even alone.

I have been taking it daily; I won't know how much it improves my Vit D deficiently until they do blood work on me again in 3 months. But the taste is good and it mixes well in my drinks.
