Natural Factors Vitamin K2+D3+A liquid drops contain three fat-soluble vitamins with complementary roles in the development and maintenance of strong bones and teeth. Menaquinone-7 (MK-7) is a highly bioavailable form of vitamin K2 derived naturally from natto beans. It assists in building bone mineral density by helping guide calcium toward the bones and away from tissues, such as the arteries, where it can be damaging. Only the MK-7 form has been shown to offer 24-hour protection in a single daily dose. Vitamin D3 is the natural cholecalciferol and most bioavailable form of vitamin D. It plays a key role in the absorption of calcium and phosphorus, two minerals that are vital for proper bone mineralization and turnover. Palmitate does not need to be converted by the body from carotenoids, making it a reliable form of vitamin A for supporting eyesight, night vision, and healthy skin and mucous membranes. Like vitamin D, vitamin A also helps support the immune system. Each daily drop of this convenient liquid formula provides 50 mcg of vitamin K2, 1000 IU of vitamin D3, and 500 IU of vitamin A in a neutral-tasting base of MCT and organic flaxseed oils. It is non-GMO, suitable for vegetarians, and contains 120 doses per bottle.

Why people keep reordering it

D3 paired with K2: The combination that helps steer calcium toward your bones.
Built for Canadian winters: Tops up the vitamin D most of us run low on from October to April.
Bone and immune support: Foundational for immune function and long-term bone strength.

Best suited to: already taking a calcium supplement, anyone who hates swallowing more pills, wants preformed vitamin a, not carotene, eats little natto, cheese or leafy greens.

What the research supports

Four drops give 1000 IU of D3 and 50 mcg of K2 as MK-7, in a flaxseed oil base with vitamin A. The 30 mL bottle lasts 120 days.

K2 trials use 45 to 180 mcg; D3 trials use 2000 to 5000 IU.

Calcium absorption (evidence: strong, from randomized controlled trial, meta-analysis): Cholecalciferol raises blood vitamin D, which increases how much calcium the gut absorbs from food. That supports normal bone mineralization over time.
Night vision (evidence: strong, from randomized controlled trial, meta-analysis): Retinol from vitamin A is the direct building block for rhodopsin, the pigment the retina uses to detect light in dim conditions.
Bone proteins (evidence: moderate, from randomized controlled trial): MK-7 activates osteocalcin, the protein that binds calcium into bone. At 45 to 180 mcg a day it reliably switches that protein on.

Is it right for you

Worth it if

Already taking a calcium supplement: MK-7 and D3 are the two cofactors calcium depends on, and 50 mcg of MK-7 plus 1000 IU of D3 covers both in one drop.
Anyone who hates swallowing more pills: Four drops off a dropper replaces three separate softgels, and the oil base means no capsule shell at all.
Wants preformed vitamin A, not carotene: Palmitate is retinol itself, so the 500 IU counts whether or not you convert carotenoids efficiently.
Eats little natto, cheese or leafy greens: MK-7 comes almost entirely from fermented foods, and 50 mcg is well above what a typical Canadian diet supplies.

Look elsewhere if

Someone with a confirmed low vitamin D level: A standalone D3 at 2500 IU or higher per drop. Multiplying this bottle to reach that dose would multiply the vitamin A and K2 with it.
Already on a multivitamin with retinol: A D3 and K2 combination without vitamin A, since preformed retinol stacks and there is an upper limit on it.
Chasing the 180 mcg bone density dose: A standalone MK-7 capsule at 180 mcg, which is the dose used in the long bone density trials.

What to expect

Nothing you can feel. A blood 25-hydroxyvitamin D level typically climbs over 8 to 12 weeks of daily use, and the K2 and A effects are only visible in lab markers or a scan. Judge this one by bloodwork, not by sensation.

How it compares

Compared with plain vitamin D3 drops: Adds 50 mcg of MK-7, which activates the proteins that direct calcium into bone rather than leaving it in soft tissue, plus 500 IU of retinol. The tradeoff: You pay more per drop and you cannot adjust the D3 without also changing your A and K2 intake. If all you need is D3, plain drops are cheaper.
