NOW Vitamina D-3 y K-2, 1000 UI/45 mcg, 120 cápsulas veganas

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 maintain bone and cardiovascular health. Vitamin D3 promotes calcium absorption in the intestine, while vitamin K2 helps direct calcium to the bones and teeth, preventing its accumulation in blood vessels. This combination is especially valued by those seeking comprehensive care for the skeletal and circulatory systems.

NOW offers this formula in convenient vegan capsules, with 1000 IU of vitamin D3 and 45 mcg of vitamin K2 per capsule, in a 120-count package.

Health Benefits

Vitamins D3 and K2 have authorized health claims by the European Food Safety Authority (EFSA). Recognized key benefits include:

• Calcium and phosphorus absorption: Vitamin D contributes to the normal absorption and utilization of calcium and phosphorus.
• Bone maintenance: Both vitamin D and vitamin K contribute to the maintenance of normal bones.
• Blood calcium levels: Vitamin D contributes to the maintenance of normal blood calcium levels.
• Blood coagulation: Vitamin K contributes to normal blood coagulation.

Additionally, vitamin D3 also contributes to the normal functioning of the immune system. NOW includes this combination as part of a healthy lifestyle.

How to choose the best D3 and K2 supplement?

When selecting a vitamin D3 and K2 supplement, it is important to consider the dosage and the form of vitamin K2. K2 can be found as menaquinone-4 (MK-4) or menaquinone-7 (MK-7). MK-7 has a longer half-life, allowing for sustained release. NOW uses a high-quality form of K2, although the exact type is not specified on the packaging. The 1000 IU dose of D3 is adequate for general maintenance, while 45 mcg of K2 complements its action.

Other factors to consider include certifications: this product is non-GMO, kosher, and soy-free. Furthermore, NOW undergoes rigorous GMP quality controls and has ISO/IEC accredited laboratories to ensure stability and potency.

Recommended dosage

The recommended dosage for adults is one (1) capsule daily, preferably with a meal containing fat to optimize absorption. Do not exceed the recommended daily dose. Each capsule provides 1000 IU (25 mcg) of vitamin D3 and 45 mcg of vitamin K2.

This product is intended for individuals who wish to supplement their dietary intake of these vitamins, especially those with limited sun exposure or restricted diets.

Who should take this supplement?

This supplement can be beneficial for adults looking to maintain bone and cardiovascular health, as well as for those with insufficient intake of vitamin D and K through diet. Older adults, those living in latitudes with low sunlight, or those with familial osteoporosis may consider its use. It is always advisable to consult a healthcare professional before starting any supplementation.

Possible side effects and precautions

In general, vitamin D3 and K2 are well tolerated at recommended doses. However, excessive doses of vitamin D3 can lead to hypercalcemia. Individuals taking anticoagulants (such as warfarin) should consult their doctor before taking vitamin K2, as it may interfere with the medication. Keep out of reach of young children.

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.
