Sports Research Vitamin D3 + K2 review

Sports Research Vitamin D3 + K2 is the pick for vegans and for people who want vitamin K2 in the same capsule. The D3 comes from lichens rather than lanolin, the K2 comes from chickpeas, and both sit in coconut MCT oil inside a tapioca-based PlantGel capsule that the brand says is carrageenan free. Sports Research lists Non-GMO Project Verified and Vegan Certified marks and says the product is third party tested. It also coats the softgels with turmeric powder to protect the contents from light. The 5,000 IU strength costs $16.95 for 30 servings, about $0.57 a day, or $14.41 with a 15% subscription; 2,500 and 10,000 IU versions and 60 and 120 serving sizes are also listed. That price per dose is the highest on this list, and anyone on blood-thinning medicine should ask a doctor before taking K2, as Thorne's FAQ also warns. If you only need plain D3, a cheaper bottle will do.
