THORNE Vitamina D3 + K2 Líquido con Dosificador - 30 ml (600 gotas)

What is the combination of vitamin D3 and K2?

Vitamin D3 (cholecalciferol) and vitamin K2 (menaquinone) are two fat-soluble nutrients that work synergistically to promote calcium metabolism in the body. While vitamin D3 facilitates calcium absorption in the intestines, vitamin K2 helps direct that calcium to bones and teeth, preventing its accumulation in soft tissues such as arteries or kidneys. This combination is essential for maintaining strong bones and a healthy cardiovascular system.

THORNE's liquid supplement combines both vitamins in a practical dispenser that allows precise administration of individual drops. Each 30 ml container provides approximately 600 drops, offering a convenient and long-lasting solution for those seeking a daily intake of quality nutrients.

Health Benefits

According to the European Food Safety Authority (EFSA), vitamin D contributes to the normal absorption and utilization of calcium and phosphorus, to the maintenance of normal blood calcium levels, and to the maintenance of normal bones. It also contributes to normal muscle function. For its part, vitamin K contributes to normal blood coagulation and to the maintenance of normal bones.

By combining vitamin D3 with K2, the effect of both nutrients is enhanced: D3 ensures that calcium is properly absorbed and K2 redirects it to where the body needs it. This integrated approach is especially valued by those seeking comprehensive support for bone and muscle health, as well as for the maintenance of flexible blood vessels.

How to choose the best vitamin D3 and K2 supplement?

When selecting a vitamin D3 and K2 supplement, it is important to consider the form of the vitamins, bioavailability, and product quality. Vitamin D3 (cholecalciferol) is the most effective form for raising blood vitamin D levels, while vitamin K2 in the form of menaquinone (especially MK-7) has a longer half-life than MK-4, allowing for sustained release. Although the product does not specify the subtype of K2, THORNE is known for using high-purity ingredients.

THORNE's liquid format with a dispenser facilitates accurate dosing without the need for measuring spoons, and each drop provides a consistent amount of nutrients. In addition, this supplement has undergone third-party testing to verify that the contents of the container match what is indicated on the label and that it does not contain unsafe levels of contaminants. Thorne is a trusted brand used by over 100 professional sports teams and is the #1 clinical brand recommended by consumers and healthcare professionals, according to an independent survey conducted in 2026.

Recommended Dosage

The integrated dispenser allows drops to be administered directly into the mouth or mixed with water or juice. Although the optimal dose may vary according to individual needs, it is recommended to follow the manufacturer's or healthcare professional's instructions. Each drop contains a precise amount of vitamin D3 and K2, and the 30 ml container offers approximately 600 drops, which is equivalent to several months if one drop is taken daily. Do not exceed the recommended daily dose.

Who should take this supplement?

This supplement is intended for people who wish to maintain optimal bone and muscle health, especially those with limited sun exposure, advanced age, or who follow restrictive diets. It may also be useful for those seeking additional support for calcium absorption, such as athletes or women during menopause. However, it is not a substitute for a balanced diet or a healthy lifestyle.

As with any food supplement, it is recommended to consult a healthcare professional before starting its consumption, especially in case of pregnancy, lactation, or if you are taking anticoagulant medications or treatments for calcium metabolism disorders.

Food supplements should not be used as a substitute for a balanced diet. Do not exceed the recommended daily dose. Keep out of reach of young children.
