What It Actually Costs
Quality vitamin D3 costs $5-15/month at effective doses (2,000-5,000 IU daily). That's about $0.15-0.50 per day.
Budget options: Kirkland Signature D3 5,000 IU (365 softgels for ~$12). That's $1/month. Not a typo.
Mid-range: NOW Foods, Nature Made, Solgar. $8-15 for 3-4 month supply.
Premium: Thorne, Pure Encapsulations. $15-25 for 2-3 month supply. Better manufacturing standards but the vitamin D itself is identical.
The price difference between brands is mostly about manufacturing quality controls and testing. The actual vitamin D3 is the same molecule everywhere.
Don't Overpay for Vitamin D Combos
"Vitamin D + K2 + Magnesium" combo products cost 3-5x more per dose of vitamin D. Sometimes the combo makes sense (K2 does help direct calcium). But you can buy D3 and K2 separately for less.
Avoid vitamin D in expensive multivitamins. The dose is usually too low (400-800 IU vs the 2,000-5,000 IU most people need). You'll need the standalone anyway.
Key Takeaways
$5-15/month for one of the most impactful supplements you can take. If cost is a concern, vitamin D is the first supplement to buy. The return on investment is unmatched.
