Sports Research Vitamin D3 + K2 10,000 IU Softgel

Vitamin D3 + K2 10,000 IU

Sports Research
(1,100)
Staff PickProprietary blend
1 softgel per day (60-day supply)

Sports Research Vitamin D3 + K2 at 10,000 IU earns a strong recommendation for the specific population it targets: adults with documented vitamin D deficiency, those recovering from insufficiency, or individuals in northern latitudes with minimal sun exposure who need a serious therapeutic dose. The lichen-sourced D3 fills a genuine market gap for vegans who previously had no access to high-potency D3 in plant-based form. The inclusion of K2 as MK-7 alongside MCT oil represents evidence-informed formulation — both additions have documented benefit for maximizing D3 effectiveness and safety. The 4.8-star rating across 1,100+ reviews is exceptional social proof for a relatively new SKU.
