K2 + D3
K2 + D3 pairs 125mcg of vitamin D3, 5,000 IU, with 100mcg of vitamin K2 as MK-7, plus 210mg of calcium and 5mg of BioPerine black pepper extract. One capsule.
The pairing is the point. Vitamin D helps your body absorb calcium, and vitamin K2 helps direct that calcium toward bone. Taking D3 alone leaves half the job unfinished, which is why these two belong in the same capsule. If you train indoors, live through a Pacific Northwest winter, or spend your daylight hours at a desk, you are in the group that most often runs low on vitamin D. This one supports the bone strength, immune function, and muscle function that a heavy training schedule leans on.*
