Bronson Vitamin D3 K2 (MK-7) Supplement - 5000 IU D3 & 90 mcg K2, 120 Capsules

Key Health Benefits

This combination of vitamin D3 and K2 (MK-7) contributes to the maintenance of normal bones and teeth, normal immune function, and normal blood clotting. Vitamin D3 aids normal calcium absorption and utilisation, while K2 supports the regulation of calcium in the body. These well-established roles, recognized by the European Food Safety Authority (EFSA), make this duo a valuable addition to your daily routine for overall wellness.

What to Look For in a D3 + K2 Supplement

When selecting a supplement, consider the form of vitamin K2. MK-7 (menaquinone-7) is preferred due to its longer half-life, providing sustained support throughout the day. A common effective ratio is 5000 IU (125 µg) of D3 with 90 µg of K2 MK-7, as in this Bronson product. Look for third-party testing for purity and potency. This formula is non-GMO, gluten-free, and soya-free, manufactured in a state-of-the-art facility in New York. Bronson has been a trusted brand since 1960, recommended by health care professionals.

Understanding the Synergy: How D3 and K2 Work Together

Vitamin D3 (cholecalciferol) enhances calcium absorption in the gut, but that calcium must be directed appropriately. Vitamin K2 activates two key proteins: osteocalcin, which binds calcium to the bone matrix, and matrix GLA protein (MGP), which helps prevent calcium deposition in soft tissues. This synergy ensures calcium supports bone density and arterial health. The MK-7 form of K2 has a longer half-life than MK-4, offering consistent activity.

Why Take Vitamin D3 and K2 Together?

Many people take vitamin D alone, but without adequate K2, absorbed calcium may not be properly utilised. Combining them optimises individual benefits: D3 boosts calcium absorption, while K2 directs it to bones and teeth and away from arteries. This partnership is particularly beneficial as we age, supporting skeletal strength and cardiovascular function.

Recommended Dosage

The suggested serving is one capsule daily, providing 5000 IU of vitamin D3 and 90 µg of vitamin K2 (MK-7). For optimal absorption, take with a meal containing fat. Individual needs vary, so consulting a health care professional is advised, especially if you have existing conditions or take medication.

Frequently Asked Questions

When is the best time to take D3 and K2? Both are fat-soluble, so taking them with a meal that includes fat may enhance absorption. Many find breakfast or lunch convenient. Can I take them separately? Yes, but the combination ensures convenience and optimal synergy. Are there any side effects? Generally well tolerated. If you take anticoagulants like warfarin, consult your doctor before taking vitamin K2, as it may interact. Is this suitable for vegans? Vitamin D3 is typically derived from lanolin (sheep's wool), so this product is not vegan. The K2 MK-7 may be from natto or synthetic sources; check the label.
