Nutra BioGenesis Vitamina D3/K2 Emulsión - Gotas líquidas de vitamina D con aceite MCT, suplemento de D3 K2 para adultos y niños, gotero sublingual - 30 ml

What is the D3 and K2 vitamin combination?

Vitamin D3 (cholecalciferol) and vitamin K2 (menaquinone, also known as MK-4) are two fat-soluble nutrients that work synergistically to support calcium metabolism in the body. While vitamin D3 helps absorb calcium from the diet, vitamin K2 helps direct it to the bones and teeth, preventing its accumulation in soft tissues. This liquid emulsion combines both vitamins in an MCT oil (medium-chain triglycerides) base to optimize their sublingual absorption.

The dropper presentation allows for flexible dosing and rapid absorption, ideal for both adults and children who prefer to avoid pills. Each 30 ml bottle provides a concentrated and easy-to-administer dose.

Health benefits

Vitamins D3 and K2 contribute to various essential physiological processes. According to claims authorized by the EFSA (European Food Safety Authority):

• Vitamin D contributes to the normal absorption and utilization of calcium and phosphorus.
• Vitamin D contributes to the maintenance of normal blood calcium levels.
• Vitamin D contributes to the maintenance of normal bones.
• Vitamin D contributes to the normal functioning of the immune system.
• Vitamin K contributes to normal blood clotting and the maintenance of normal bones.

In addition, the combination of D3 and K2 helps ensure that absorbed calcium is properly deposited in bone tissue, thus supporting skeletal and dental health.

How to choose the best D3 and K2 supplement?

When selecting a vitamin D3 and K2 supplement, it is important to consider the form of each nutrient and the delivery vehicle. Vitamin D3 (cholecalciferol) is the most bioavailable form, and vitamin K2 as menaquinone (MK-4) offers fast and effective action. Suspension in MCT oil not only improves the absorption of these fat-soluble vitamins but also facilitates sublingual administration, bypassing the digestive system.

Factors such as product purity, the absence of artificial additives, and vegan and gluten-free certifications are signs of quality. This supplement meets all these requirements, being suitable for restricted diets.

Recommended dosage

The dose may vary according to individual needs. It is recommended to follow the manufacturer's instructions or consult a healthcare professional. Generally, a daily dose of 1-2 drops (depending on concentration) provides an adequate amount of D3 and K2. Shake well before use and administer directly under the tongue or mix with a drink. Do not exceed the recommended daily dose.

Who should take it?

This supplement is indicated for people who wish to maintain optimal bone health, those with limited sun exposure during the winter months, or those following diets that may be low in these nutrients. It is also suitable for older adults, postmenopausal women, and people with reduced intestinal absorption. Being liquid and gluten-free, it is suitable for children and people with food sensitivities.

Possible side effects

Vitamins D3 and K2 are generally safe when consumed at recommended doses. Excessive intake of vitamin D3 can lead to hypercalcemia (high calcium levels in the blood), so it is important not to exceed the indicated dose. Vitamin K2 has a favorable safety profile and no significant adverse effects have been described with normal doses. As with any supplement, consult a doctor before use if you are pregnant, breastfeeding, or taking anticoagulant medications (due to interaction with vitamin K).

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.
