The science behind our ingredients
Vitamin D3 5000 + K2
Is this right for you?
Vitamin D3 5000 + K2
Is this right for you?
- 01You're focused on long-term bone health
Bone density depends on both vitamin D and the K2 needed to direct calcium where it belongs. Most D supplements skip K2 — this formula includes both at clinical doses.
- 02You want vitamin D and K2 in one supplement
Most vitamin d3 and k2 supplements split them across two products. This formula combines clinical doses of both in a single daily capsule, simplifying your routine.
- 03You have limited sun exposure
Vitamin D deficiency is widespread, especially in northern climates and for people who work indoors. A high-potency vitamin D3 K2 supplement is a reliable way to maintain healthy levels.
- 04You're focused on cardiovascular health
K2 helps keep calcium out of arterial walls, supporting healthy arteries. The D3 + K2 pairing is one of the most-recommended combinations for long-term heart health.

why we’re different
Not all supplements are created equal.
At Parsley, ‘professional grade’ means every supplement is third-party tested for quality and purity, and manufactured in NSF/USP-certified, cGMP-compliant U.S. facilities that meet FDA standards.
Our clinicians know which supplements actually move the needle — and which don't. Every formula is selected for clinical evidence, optimal bioavailability, and meaningful dosing. Not what's cheapest to manufacture. What actually works.

I am so excited we are finally offering this in one convenient pill. K2 helps keep our arteries from building up too much calcified plaque.
