Between 2009 and 2014, researchers at Maastricht University Medical Center ran a 3-year, double-blind, placebo-controlled trial on 644 adults. The intervention: 200mcg of natural MK-7 daily, suspended in a fat carrier. The result: significant bone density improvement and reduced vertebral height loss versus placebo.
The problem is what happens when you try to buy that formula off a shelf.
Most D3+K2 supplements use MK-4 instead of MK-7 — a form with a 90-minute half-life that's cleared from your body before lunch. They underdose at 45–90mcg instead of the clinical 200mcg. And they deliver it in dry pressed tablets, which is biologically backwards — D3 and K2 are fat-soluble and need oil to absorb.
Maren is built to match the trial exactly. 200mcg of natural MK-7. Suspended in organic coconut oil. In a softgel that bypasses digestive breakdown. 72-hour half-life so it actually stays in circulation long enough to activate the proteins. The same dose, the same form, the same delivery the science requires — nothing less. This is what it takes to rebuild bone density naturally.
