Today Only Microbiome Labs MegaQuin K2+D3

Studies show the majority of endurance athletes have insufficient vitamin D levels, especially through winter training. Low D quietly erodes muscle strength, slows recovery, and raises your stress fracture risk. But here’s the part most athletes miss: taking D3 alone isn’t enough. Without K2, the calcium that D3 pulls into your bloodstream has nowhere to goand it can end up in your arteries instead of your bones.

MegaQuin K2+D3 pairs high-potency vitamin D3 with the most bioactive form of K2 available, making sure your calcium actually does its job.

Natural K2Not Synthetic Most K2 supplements on the market use synthetic forms that contain up to 40% inactive isomersmeaning a significant portion of what you’re swallowing doesn’t fully work. MegaQuin uses MenaquinGold® MK-7, naturally derived from chickpea fermentation, producing 100% trans isomer K2: the only form your body fully recognizes and uses.

K2 Directs Calcium. D3 Absorbs It. Vitamin D3 opens the door for calcium absorption in your gut. K2 (MK-7) then acts as the traffic controlleractivating proteins that pull calcium into bone and away from arteries and soft tissue. Together they do something neither can accomplish alone: put calcium exactly where endurance athletes need it most.

Broad Metabolic Coverage in One Capsule Beyond bone, this combination supports cardiovascular function, healthy nerve signaling, mitochondrial function, and immune responsethe full stack of systems that take a beating during heavy training blocks.

How to Use MegaQuin K2+D3

Daily Dose: 1 capsule daily with a meal (D3 and K2 are fat-solublefood improves absorption).

Timing: With your largest meal of the day for best uptake.

Pro Tip: Get your vitamin D levels tested. Most labs flag deficiency below 20 ng/mL, but optimal athletic function is generally associated with levels above 40 ng/mLknowing your baseline tells you if you need additional D3 support alongside this formula.

Stop taking D3 and hoping for the best. MegaQuin K2+D3 makes sure the calcium you absorb actually builds the bones and supports the cardiovascular system you’re training so hard to protect.
