Description
What Are Our Vitamin D3 4000IU Tablets?
Vitamin D is naturally produced by the body when exposed to sunlight and can be found in certain foods such as oily fish, eggs and mushrooms. However, it can be difficult to meet daily needs for vit. D3 through diet and sunshine alone. If you're not getting enough sunlight and would like a vegetarian alternative source of vitamin D3, these Vitamin D 4000IU Tablets are a great option.
Each serving of our potent vitamin D3 supplements provides 4000IU of vitamin D3 to support your everyday well-being. With 400 micro tablets per bottle, you’ll have over a year’s supply of D3 goodness without reordering. Simply take one tablet a day to help maintain your daily intake of the sunshine vitamin effortlessly.
