What We Like

  • Most popular vitamin D3 on Amazon US with 100,000+ ratings
  • 5,000 IU is the optimal daily dose for most US adults (per Endocrine Society guidelines)
  • Extra-virgin olive oil base improves D3 absorption (fat-soluble vitamin)
  • Ridiculously affordable — less than $0.04 per serving
  • NOW Foods has been a trusted US brand since 1968

What We Don't

  • 5,000 IU may be too high for some individuals (test your levels first)
  • Softgel format (not suitable for vegans — gelatin capsule)
  • No added K2 (many vitamin D experts recommend taking with K2)
  • Bottle is large plastic — not travel-friendly

Frequently Asked Questions

Do Americans really need vitamin D supplements?

The CDC estimates that over 40% of US adults are vitamin D deficient, especially in northern states and during winter. Supplementation is widely recommended by US healthcare providers.

Should I take K2 with D3?

Many experts recommend it. K2 directs calcium to bones instead of arteries. NOW makes a D3+K2 combo if you prefer one capsule.

How long does 240 softgels last?

At 1 per day, 8 months. At roughly $8 for the bottle, that's $1 per month — the best value supplement in this review.
