Overview
Sports Research packages 5000 IU (125 mcg) of vitamin D3 into a liquid softgel base of coconut derived MCT oil, sold in a 360 count bottle that covers close to a year of daily use. It is labeled Non-GMO, gluten free and soy free, and carries a tree nuts allergen note tied to the coconut oil base.
Vitamin D3 is fat soluble, so pairing it with an oil like MCT inside a softgel is meant to help absorption more consistently than a dry tablet, which is the main reason brands in this category favor a liquid softgel. At 5000 IU per softgel, the dose sits well above standard multivitamin levels and is typically used to address a known low vitamin D status rather than general maintenance, so checking blood levels or talking to a doctor before starting a dose this high is worth doing. The tree nuts flag on an otherwise coconut based product is worth a second look for anyone with a genuine tree nut allergy.

- Non-GMO, gluten free, soy free
- Tree nuts allergen flag on the label
Who it's for
This fits people advised to take a higher dose of vitamin D3, or who prefer an oil based softgel over a dry tablet for absorption reasons. It is not the right pick for anyone with a coconut or tree nut allergy, or someone who only needs a standard, low dose maintenance amount.
Strengths and trade-offs
Drawn from this product's published specifications.
- High 5000 IU D3 dose per softgel
- Liquid softgel in MCT oil for fat soluble absorption
- Non-GMO, gluten and soy free
- 360 count lasts close to a year at one a day
- Dose is high enough to warrant medical guidance before starting
- Tree nuts allergen note despite coconut sourcing
Performance notes
Delivering vitamin D3 dissolved in MCT oil inside a softgel takes advantage of the vitamin's fat solubility, since dry tablet forms depend more on having dietary fat present at the same meal to absorb well. At 5000 IU, this dose is roughly six times what many standard multivitamins provide, which is why it is generally aimed at correcting a measured deficiency rather than everyday maintenance. Monitoring blood levels periodically is the usual safeguard when taking a fat soluble vitamin at a high dose over time.
