Vitamin D-5000
Thorne is a clinical-grade brand, and this product carries the NSF Certified for Sport seal, providing the highest level of third-party verification available. While it lacks the lipid-based delivery system and K2 cofactors mentioned in our gold standard, its purity and brand reliability make it a top choice for high-dose supplementation.
