Parsley Health's Vitamin D3 + K2 supplement delivers 1,000 IU of vitamin D3 (cholecalciferol) and 10 mcg of vitamin K2 as MK-7 per drop, in a liquid format that sets it apart from conventional capsule supplements.

D3 and K2 are essential partners: vitamin D3 enhances calcium absorption, while vitamin K2 in its MK-7 form directs that calcium into your bones instead of letting it accumulate in soft tissues and arteries. Together, they support bone density, cardiovascular health, immune function, and may offer protection against osteoporosis and deficiency-related cognitive decline. Taking them separately misses the synergy, this formula delivers both in one precisely dosed product.

The liquid drops format offers two advantages over capsules: fat-soluble vitamins like D3 and K2 are absorbed more efficiently in an oil-based delivery medium (this formula uses MCT oil), and flexible dosing lets you take anywhere from 2 to 10 drops daily based on your individual needs or provider guidance. This is especially useful for people who are correcting a significant deficiency, who cannot swallow pills, or who want to titrate their vitamin D intake under clinical supervision.

Every Parsley Health supplement is third-party tested for quality and purity and manufactured in the U.S. at NSF- or USP-certified, cGMP-compliant facilities that meet FDA standards.
