Overview
NOW Foods Vitamin D-3 5,000 IU is a high-potency softgel supplement sold in a 240-count bottle, model 0373, positioned for structural support.
At 5,000 IU per softgel, this sits well above the maintenance doses found in many multivitamins, so it functions as a dedicated single-nutrient supplement rather than a general multi. No ingredient attributes, seller description or reviews accompany this listing, so the softgel format and potency in the title are what the entry can speak to. The 240-count size supports an extended daily supply before reordering.
- 5,000 IU vitamin D-3 per softgel
- 240 softgels per bottle
- High potency formula
- Model 0373
Who it's for
Suited to adults whose healthcare provider has recommended a higher-dose vitamin D3 than a standard multivitamin provides. Not the right choice for anyone who only needs a low, maintenance-level dose or prefers a non-gelatin softgel.
Strengths and trade-offs
Drawn from this product's published specifications.
- High potency 5,000 IU per softgel
- 240-count bottle for extended daily use
- Softgel format, generally easy to swallow
- No ingredient, allergen or diet attributes listed
- Dose is high enough that it should suit an actual need, not casual maintenance
Performance notes
At 5,000 IU per softgel, the dose is roughly several times the daily value found in most general multivitamins, which is why products at this potency are typically taken as a targeted supplement rather than part of a broader stack. Softgels are generally easier to swallow than tablets of the same dose and tend to absorb fat-soluble vitamin D more readily when taken with a meal. No further ingredient or allergen data was provided for this listing.
