Liquid D3 Ultra delivers 125 mcg of vitamin D3 - 5,000 IU, 625% DV - in five drops (0.11 mL), suspended in extra virgin olive oil with d-alpha tocopherol as a natural preservative. A 0.43 fl oz bottle.

The olive oil carrier is doing real work, not decorating the label. Vitamin D is fat-soluble, meaning it needs dietary fat present to absorb - which is why a D3 tablet taken on an empty stomach performs poorly, and why an oil suspension sidesteps the problem entirely. D3 is cholecalciferol, the form the skin produces from sunlight, and it supports normal calcium absorption, bone maintenance, and immune function. At 5,000 IU this is the serving customers with limited sun exposure look for, and the dropper lets them take less if they want less.

Fat-soluble vitamin in an oil base is the formulation done properly, and the tiny bottle holds a long supply. Take five drops daily, or as directed by a healthcare professional.
