XPRS Nutra Vitamin D3 Powder (Cholecalciferol) - Unflavored VIT D Powder for Bone Health and Immune Support - Vitamin D3 Powder Supports Muscle Function - Vitamin D Powder Supplements (8 oz)

Had a problem with soft shell eggs and read a blog that recommended this, working great for my chickens. I sprinkle a little bit on the fermented food I mix for them along with oyster shell flour and mix it through. So far seems to be working great.

if you don't mind taking 1/8 tsp once a week, then you can get alot of bang for the buck.1/8 tsp is about 50,000 iu according to my calculation. vit d is fat soluble so can be stored in body and don't need to take every day.

Do not buy - there is no ability to translate a weight/volume of this product to an appropriate dosing IU. There are additives like starch sodium succinate, sucrose, and maltodextrin so you cannot do the conversion yourself. Tried to reach out to the company but no response yet - will likely return soon if I don’t hear back

Economical. Easy to put in your favorite liquid.

works great
