Overview

Nature's Truth Vitamin D3 delivers 400 IU (10 mcg) of vitamin D3 per tablet in a 100 count bottle. It is a vegetarian, non-GMO, gluten free tablet aimed at basic daily immune support.

This is a lower dose D3 tablet compared to the 1000 IU or higher doses common in many D3 products, which matters if you compare bottles by potency rather than count. The vegetarian tablet format and non-GMO, gluten free labeling put it in line with what buyers typically look for in a straightforward daily vitamin.

  • 400 IU (10 mcg) vitamin D3 per tablet
  • 100 tablets per bottle
  • Vegetarian, non-GMO, gluten free
  • Labeled for immune support

Who it's for

Fits someone who wants a modest, tablet form daily vitamin D3 dose without capsules or softgels, and who prioritizes vegetarian and gluten free labeling. Not the choice for someone whose doctor has recommended a higher IU dose.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Vegetarian tablet, no gelatin
  • Non-GMO and gluten free
  • Simple, unflavored daily D3 dose
What to check first
  • 400 IU is a lower dose than many competing D3 products
  • No additional nutrients paired with the D3

Performance notes

At 400 IU per tablet, this sits at the lower end of common vitamin D3 dosing, closer to older RDA guidance than the 1000 to 5000 IU tablets many other D3 products now carry. The tablet form, rather than softgel, is generally easier to split and avoids any oil sensitivity concerns.
