is a two-ingredient, olive oil-based liquid vitamin D and K supplement delivering 500 IU of Vitamin D3 (as Cholecalciferol) and 50 mcg of Vitamin K2 (as Menaquinone-4 / MK-4) per single drop, in a pure olive oil carrier with no fillers, no flavors, no preservatives, and no sweeteners — designed for the whole family, suitable for children from age one and adults of all ages, and ideal for anyone who needs precise, flexible D3/K2 dosing or has difficulty absorbing or swallowing capsule-based supplements.

Vitamin D3 and K2 are two of the most important fat-soluble vitamins in the body, and they work as a biological pair. D3 drives calcium absorption in the gut, pulling calcium from food and supplements into circulation. Without K2 to direct where that calcium goes, elevated circulating calcium can deposit in arteries and soft tissue rather than reaching bone and teeth where it belongs. Vitamin K2 activates two key calcium-directing proteins: osteocalcin, which incorporates calcium into bone matrix, and Matrix Gla Protein (MGP), which prevents arterial calcification by clearing calcium from vascular walls. Together D3 and K2 create a functional system where calcium is not just absorbed but properly placed, making them genuinely more effective together than either can be alone.

The MK-4 form of K2 used in this formula is a soy-free alternative to MK-7, which is typically derived from fermented soybeans. MK-4 is the natural form produced in human tissue and is the form found in animal foods, making it a clean, soy-free choice for those managing soy sensitivities, histamine concerns, or who simply prefer a non-fermented K2 source. The olive oil base serves a critical functional purpose: D3 and K2 are both fat-soluble vitamins that require dietary fat for absorption. By delivering them pre-dissolved in olive oil, this formula provides the lipid environment they need for optimal absorption without requiring the supplement to be taken with a fatty meal.

At 500 IU of D3 per drop, this formula offers exceptionally flexible dosing. One drop delivers a gentle maintenance level appropriate for young children or those already receiving D3 from other sources. Two to four drops daily provides meaningful therapeutic support for adults. Eight to ten drops delivers the equivalent of a standard 5,000 IU capsule dose for those with documented deficiency or elevated needs. This flexibility makes Seeking Health D3 + K2 Drops the ideal choice for families who need a single product that can serve every member at the appropriate dose, and for practitioners who need precise titrated dosing for their clients.

Vitamin D3 (as Cholecalciferol) — 500 IU (12.5 mcg) — Cholecalciferol is the most bioavailable and clinically studied form of supplemental vitamin D, identical to the form synthesized in human skin upon UVB sunlight exposure. D3 supports calcium and phosphate absorption in the gut, healthy bone mineralization, immune cell regulation, mood and cognitive function, healthy inflammatory balance, and gene expression across virtually every tissue in the body. At 500 IU per drop, this formula allows dosing to be adjusted precisely based on individual lab values, body weight, age, sun exposure habits, and clinical need. Derived from cholesterol in sheep's wool, suitable for vegetarians.

Vitamin K2 (as Menaquinone-4 / MK-4) — 50 mcg — MK-4 is the naturally occurring, tissue-derived form of vitamin K2 found in animal-based foods including meat, eggs, and dairy. Unlike MK-7, which is fermented from soybeans, MK-4 is a soy-free, non-fermented K2 form that is directly bioavailable without conversion. MK-4 activates both osteocalcin (directing calcium into bone matrix) and Matrix Gla Protein (preventing arterial calcium deposition), making it functionally essential for the safe and effective use of Vitamin D3 supplementation. At 50 mcg per drop, K2 dosing scales naturally alongside D3 as drops are adjusted upward.

Olive Oil — The sole other ingredient. Extra virgin olive oil provides the lipid environment required for the absorption of D3 and K2 as fat-soluble vitamins. No fillers, sweeteners, preservatives, or synthetic additives of any kind.

Keep closed in a cool, dry place away from direct sunlight. Keep out of reach of children.
