Overview

Nature's Bounty Vitamin D3 delivers 1000 IU per softgel in a 350-count bottle, model 30413, meant for one softgel a day to support immune function and bone health.

At 1000 IU, the dose sits at a standard maintenance level rather than the higher potency seen in some other vitamin D3 products, making it suited to daily upkeep rather than addressing a diagnosed deficiency. The 350-count size is built around close to a year of once-daily use before a refill is needed.

  • 1000 IU vitamin D3 per softgel
  • 350 softgels per bottle
  • Supports immune function and healthy bones
  • Gluten free

Who it's for

Fits people wanting a standard-dose, everyday vitamin D3 softgel for long-term use rather than a high-potency or short-term supplement. Not the choice for anyone whose provider has recommended a higher IU dose.

Pros and cons

Pros
  • 1000 IU standard daily dose
  • 350-count bottle lasts close to a year
  • Gluten free softgel
  • Supports immune function and bone health
Cons
  • Lower potency than some vitamin D3 products on the market

Performance notes

At 1000 IU per softgel, this is a maintenance-level dose intended for daily immune and bone health support rather than correcting a deficiency, which typically calls for a higher-dose product. The 350-count bottle covers close to a year of once-daily servings, which is the main practical advantage of buying at this size. Being gluten free is the only allergen note supplied with the listing.
