THORNE’s Vitamin D + K2 Liquid delivers a highly absorbable blend of vitamins D3 and K2 in a concentrated liquid format. Each metered dose provides exactly 25 mcg (1000 IU) of vitamin D3 and 45 mcg of vitamin K2 (as menaquinone-4), allowing for precise supplementation without guesswork. The formula is designed to support bone density and muscle function by enhancing calcium absorption and directing it to the skeletal system.* This liquid form bypasses the need for large capsules, making it suitable for individuals who prefer a few drops over swallowing pills. With 600 servings per bottle, it offers long‑lasting value at a very affordable price. The ingredients are sourced with rigorous quality standards, free from unnecessary additives, and the product is third‑party tested for purity and potency. The convenient metered dispenser ensures consistent dosing, whether added to water, juice, or taken directly. This formulation is ideal for adults seeking to maintain strong bones and healthy muscles as part of a daily regimen, especially those with limited sun exposure or dietary intake of vitamin D and K2. The liquid’s neutral taste and easy absorption make it practical for everyday use. The vitamin D3 used is derived from lanolin, a natural source, while the K2 is the well‑researched MK‑4 form, known for its bioavailability.

Together, these nutrients work synergistically to support calcium metabolism and overall musculoskeletal health.* The product is free from gluten, dairy, soy, and artificial colors, catering to various dietary preferences. Its compact 1 fl oz (30 ml) bottle is travel‑friendly, and the dispenser’s design minimizes waste. Regular use of this liquid supplement can help fill nutritional gaps without requiring large doses. The 600‑serving count means a single bottle can last several months, making it a cost‑effective choice for long‑term wellness. The formulation is suitable for both men and women, and it can be taken with or without food. As with any supplement, consistency is key, and this product supports that through its simple dosing mechanism.

THORNE’s Vitamin D + K2 Liquid stands out for its precision, potency, and purity. It is a practical option for those who value high‑quality ingredients and efficient delivery, all at a reasonable price point that reflects excellent value.
