1voteA: D3 and K2 work synergistically in calcium metabolism. Vitamin D increases calcium absorption from the gut into the bloodstream. Vitamin K2 (especially the MK-7 form) activates proteins that direct that calcium specifically into bone matrix and away from soft tissue (like arteries). Without adequate K2, high-dose D3 may potentially raise blood calcium without efficiently delivering it to bone. The combination is favored for bone health and cardiovascular wellness.Posted by on Saturday, May 2, 2026

1voteA: Most Vitamin D3 (cholecalciferol) is extracted from lanolin in sheep wool — making it non-vegan but vegetarian-friendly. Vegan D3 is now produced from lichen, a symbiotic organism that naturally produces D3 in response to UV exposure. Lichen-derived D3 is molecularly identical to lanolin-derived D3 and equally bioavailable, making it the gold standard for plant-based supplementation. Sports Research uses lichen-sourced D3.Posted by on Saturday, May 2, 2026

1voteA: Both are biologically active forms of Vitamin K2 found in different foods — MK-4 in animal products, MK-7 in fermented foods like natto. The key practical difference is half-life: MK-4 is cleared from blood within hours and requires multiple daily doses, while MK-7 has a half-life of around 3 days and supports more consistent activation of K-dependent proteins on a once-daily dose. Most modern D3+K2 supplements use MK-7 for this reason.Posted by on Saturday, May 2, 2026
