Carlson Vitamin K2, MK-4 (Menatetrenone) - 5 mg, 60 Capsules

Supporting Bone and Cardiovascular Health

Maintaining strong bones and a healthy cardiovascular system is a priority for many adults as they age. Vitamin K2 plays a vital role in ensuring calcium is directed to the bones where it is needed, rather than being deposited in soft tissues. Carlson’s Vitamin K2 supplement provides 5 mg of MK-4 (menatetrenone) per capsule, a form that has been extensively researched for its contribution to the maintenance of normal bones and normal blood clotting. By activating osteocalcin and matrix Gla protein, vitamin K2 supports proper calcium utilisation throughout the body.

Who Might Benefit from Vitamin K2 Supplementation?

Individuals who may benefit from vitamin K2 include those concerned with bone density, women after the menopause, older people, and anyone with a limited dietary intake of vitamin K2-rich foods such as egg yolks and dairy. Those supplementing with vitamin D or calcium often pair them with vitamin K2 to encourage calcium to be directed to bones rather than soft tissues. If you have a history of cardiovascular issues or are taking blood-thinning medication, consult your health care professional before starting supplementation. Vitamin K2 is generally well-tolerated, but professional guidance is recommended for personalised dosing.

Understanding MK-4 and MK-7

Vitamin K2 exists in several forms, with MK-4 and MK-7 being the most common in supplements. MK-4 (menatetrenone) has a shorter half-life and is rapidly metabolised, making it ideal for frequent dosing. MK-7 (menaquinone-7) is derived from natto and remains active in the body longer. Both forms contribute to bone maintenance and normal blood clotting, but MK-4 has been studied extensively for its role in bone health and is often preferred by those seeking precise control over their intake. Carlson’s Vitamin K2 provides 5 mg of MK-4 per capsule, a well-researched dosage for daily support.

Selecting a High-Quality Vitamin K2 Supplement

When choosing a vitamin K2 supplement, consider the form, purity, and manufacturing standards. Carlson’s Vitamin K2 is soy-free, making it suitable for individuals with soy sensitivities. Each batch is tested by an independent, UKAS-accredited laboratory for potency and quality—a practise Carlson has followed since 1965. The capsules are free from common allergens and artificial additives, ensuring a clean supplement. Look for products that clearly state the amount of active menaquinone (e.g., 5 mg MK-4) and avoid unnecessary fillers.

Dosage and Important Considerations

Carlson’s Vitamin K2 provides 5 mg (5000 mcg) of MK-4 per capsule. The recommended serving is one capsule daily, preferably with a meal containing fat to enhance absorption. Vitamin K2 is considered safe at this dosage, with no established upper tolerable intake level. However, very high doses may interact with anticoagulant medications like warfarin. If you are taking blood thinners, seek medical advice before use. As with any supplement, store in a cool, dry place and keep out of reach of children.

What Exactly Is Vitamin K2?

Vitamin K2, also known as menaquinone, is a fat-soluble vitamin that contributes to the maintenance of normal bones and normal blood clotting. Unlike vitamin K1 (phylloquinone), which is primarily involved in blood clotting, vitamin K2 activates proteins that regulate calcium distribution. The form used in this supplement is MK-4 (menatetrenone), a short-chain menaquinone naturally present in animal foods like egg yolks and dairy. For those looking to support their bone and cardiovascular health, a high-quality vitamin K2 supplement like Carlson’s offers a convenient, soy-free option.
