Daily Defense - Vitamina D3 y K2 2000 UI, 100 Comprimidos Masticables

What is the D3 and K2 vitamin combination?

Vitamin D3 (cholecalciferol) and vitamin K2 (menaquinone) are two fat-soluble nutrients that work synergistically to support various bodily processes. Vitamin D3 promotes calcium absorption, while vitamin K2 helps direct that calcium to the bones and teeth, instead of being deposited in soft tissues. This combination is popular among those seeking a comprehensive approach to bone and cardiovascular health.

Daily Defense offers this combination in a convenient cherry-flavored chewable tablet, ideal for those who prefer to avoid large capsules. Each tablet provides 2000 IU of vitamin D3 and a dose of vitamin K2 (not specified, but typically in MK-7 form for a longer half-life).

Health benefits

According to the European Food Safety Authority (EFSA), vitamins D and K contribute to the following benefits:

• Vitamin D: Contributes to the normal absorption and utilization of calcium and phosphorus, to the maintenance of normal blood calcium levels, to the maintenance of normal bones, to the maintenance of normal muscle function and to the normal functioning of the immune system.
• Vitamin K: Contributes to normal blood clotting and to the maintenance of normal bones.

By combining both vitamins, the aim is to optimize the use of calcium in the body, supporting bone density and cardiovascular health in a complementary way.

How to choose the best supplement?

When selecting a D3 and K2 supplement, consider the following aspects:

• Form of vitamin K2: Menaquinone-7 (MK-7) has a longer half-life than MK-4, allowing for a single daily dose.
• Dosage: Usual doses range from 1000 to 5000 IU of vitamin D3 and from 45 to 180 mcg of vitamin K2. This product offers 2000 IU of D3, an adequate amount for general maintenance.
• Format: Chewable tablets are convenient and do not require water. In addition, the cherry flavor makes them easy to consume daily.
• Origin of ingredients: Vitamin D3 is usually obtained from lanolin (sheep) or lichen (vegan). This product does not specify the origin, but it is suitable for most diets.

Recommended dose

It is recommended to take one chewable tablet daily, preferably with a meal containing some fat to promote absorption. Do not exceed the recommended daily dose. The tablets can be chewed directly or allowed to dissolve in the mouth.

Who should take it?

This supplement is intended for adults who wish to maintain adequate levels of vitamin D and K, especially during periods of low sun exposure, restrictive diets or increased physical demand. It can also be useful for older people who want to support bone and muscle health. Consult a health professional before starting any supplementation, especially if you are taking anticoagulant medications or have pre-existing health conditions.

Why combine vitamin D3 and K2?

Vitamin D3 increases calcium absorption in the intestine, but without vitamin K2, that calcium could accumulate in arteries and soft tissues. Vitamin K2 activates proteins that direct calcium to the bones and teeth, where it is needed. This combination helps maximize the benefits of calcium and minimize potential risks. Many nutrition experts recommend taking them together for a more complete approach to bone and cardiovascular health.

Possible side effects

In general, this supplement is well tolerated. In high doses, vitamin D can cause hypercalcemia (excess calcium in the blood), with symptoms such as nausea, weakness or kidney problems. Vitamin K2 has a low toxicity profile, but it can interact with anticoagulants such as warfarin. Always consult your doctor before taking supplements if you have any medical condition or are taking medication.

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.
