Overview
A 5,000 IU vitamin D3 tablet from Douglas Laboratories, sold in a 100 count bottle. Unflavored and formulated to fit a keto diet, it's built for adults who need a higher daily dose than a standard multivitamin provides.
Most multivitamins cap vitamin D at 400 to 1,000 IU, so this 5,000 IU tablet is meant for people already advised to run a higher dose, not as a casual add-on. The listing flags it as abalone free, a detail shellfish-sensitive buyers may want confirmed elsewhere since the label doesn't explain the sourcing. At 100 tablets it lasts a little over three months at one a day.
- 5,000 IU vitamin D3 per tablet
- 100 tablets per bottle
- Keto-friendly, unflavored
- Labeled abalone free
Who it's for
Fits adults who have been told to take a higher-dose D3, including people managing low vitamin D levels under a doctor's guidance. Not the right pick for someone just wanting a baseline daily amount, since 5,000 IU is well above general maintenance doses.
Strengths and trade-offs
Drawn from this product's published specifications.
- Single tablet covers a full high-dose serving
- Unflavored, no added flavoring to work around
- Fits a keto diet per the label
- 100 count lasts over three months at one a day
- 5,000 IU is too strong for casual daily use
- Tablet form, not an option for people who prefer liquid or gummy D3
- No description or review data to check real-world tolerance
Performance notes
Vitamin D3 is fat soluble, so tablets like this are generally taken alongside a meal that contains some fat rather than on an empty stomach. At 5,000 IU per tablet, one dose delivers well over ten times the amount found in most standard multivitamins, which is why higher-dose products like this are typically used under guidance rather than as a default daily add-on.
