Overview
A bulk 500 count bottle of Vitamin D3 5000IU softgels from BulkSupplements.com, delivering 125mcg of cholecalciferol per softgel. Gluten free, positioned for immune support.
At 500 softgels per bottle this is built for buyers who take vitamin D daily and do not want to reorder every month, which is where BulkSupplements' pricing model tends to make sense. 5000IU is a higher daily dose than the standard 600 to 800IU RDA, common in D3 products aimed at people testing low on blood work. There is no filler or blend here, just a single-ingredient softgel.
- 5000IU cholecalciferol per softgel
- 125mcg vitamin D3 per serving
- 500 softgels per bottle
- Gluten free
Who it's for
Fits people already taking a higher-dose D3 protocol who want a long runway before reordering. Less suited to anyone who only wants a standard RDA-level dose or prefers a multivitamin approach.
Strengths and trade-offs
Drawn from this product's published specifications.
- 500 count means months of supply without reordering
- 5000IU per softgel is a higher, clinically common dose
- Gluten free single-ingredient formula
- No K2 or calcium included for buyers wanting a combination product
- 5000IU exceeds standard RDA, so it is not for casual dosing without guidance
Performance notes
Vitamin D3 (cholecalciferol) is the form the body produces from sun exposure and converts more efficiently than D2, which is why most single-ingredient D3 products use it. A softgel delivery suspends the fat-soluble vitamin in oil, which supports absorption since D3 needs dietary fat to be taken up properly.
