Is this right for you?
Vitamin D3 + K2 Supplement Drops
Is this right for you?
- 01You don't like swallowing pills
A liquid vitamin D3 + K2 supplement drops format makes daily supplementation easy for people who prefer drops — including those with difficulty swallowing capsules.
- 02You're correcting a vitamin D deficiency
Flexible dosing from 2,000 to 10,000 IU per day lets you ramp up under clinical supervision to address a significant deficiency, then taper down for maintenance.
- 03You want fat-soluble absorption support
Vitamin D3 and K2 absorb best with dietary fat. The MCT oil base of this vitamin D tincture provides the carrier needed for reliable absorption — even on an empty stomach.
- 04You want to titrate your vitamin D under guidance
Drops give you precise dose control your provider can adjust based on lab work — ideal for people working with a clinician on optimal vitamin D levels.

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.

It is so important to make sure your Vitamin D supplement has Vitamin K in it too. Vit D helps absorb Calcium, but Vit K helps keep our arteries clean & prevent calcification.
