Carlson Vitamin K2 MK-7 (Menaquinone) 45 mcg – Bone Support & Calcium Bioavailability – 90 Soft-gels

Key Differences: Vitamin K2 MK-7 vs. MK-4

Not all vitamin K2 is created equal. The two main forms are menaquinone-4 (MK-4) and menaquinone-7 (MK-7). Here's how they stack up:

• Source: MK-4 is synthetically produced in small amounts by the body from vitamin K1, while MK-7 is naturally found in fermented foods like natto and is also derived from bacterial fermentation for supplements.
• Bioavailability: MK-7 has a much longer half-life (about 3 days) compared to MK-4 (a few hours), allowing for more consistent blood levels with once-daily dosing. Studies indicate MK-7 is absorbed more efficiently and remains active in the body longer.
• Potency: MK-7 is more potent at activating osteocalcin (the protein that binds calcium to bones) and matrix Gla protein (which supports arterial flexibility) at lower doses.
• Clinical evidence: MK-7 has been extensively studied in human trials, particularly the patented MenaQ7 ingredient used in this supplement, showing significant improvements in bone mineral density and arterial flexibility.

Carlson chooses the MK-7 form to deliver superior absorption and sustained support for your bone and cardiovascular systems.

Why Vitamin K2 Is Essential for Your Health

Vitamin K2, also known as menaquinone, is a fat-soluble vitamin that plays a critical role in directing calcium to the bones and teeth while helping to prevent it from depositing in soft tissues like arteries. This unique function makes it indispensable for maintaining strong, healthy bones and supporting cardiovascular health. Unlike vitamin K1, which is primarily involved in blood clotting, K2 activates proteins that bind calcium to the bone matrix, enhancing bone density and strength. Research suggests that adequate vitamin K2 intake may help reduce the risk of fractures and improve bone mineral density, particularly when combined with vitamin D and calcium. Carlson Vitamin K2 MK-7 provides 45 mcg of this vital nutrient per soft gel, using the highly bioavailable MK-7 form derived from the clinically studied MenaQ7 ingredient.

Who Should Consider a Vitamin K2 Supplement?

While everyone can benefit from adequate vitamin K2, certain groups may be more likely to have a deficiency or need additional support. These include:

• Postmenopausal women's: Hormonal changes accelerate bone loss, making K2 crucial for maintaining bone mass.
• Older adults: Ageing reduces the body's ability to synthesise and absorb vitamin K2.
• Individuals with osteoporosis or low bone density: K2 helps maximise the effectiveness of calcium and vitamin D therapy.
• Those taking certain medications: Long-term use of antibiotics, statins, or blood thinners (like warfarin) can interfere with vitamin K metabolism.
• People with digestive disorders: Conditions like Crohn's disease or coeliac disease may impair fat absorption, reducing K2 uptake.
• Vegans and vegetarians: Dietary sources of K2 (natto, organ meats, cheese) are limited in plant-based diets.

If you fall into any of these categories, supplementing with a high-quality vitamin K2 like Carlson's MK-7 may help fill nutritional gaps.

How to Choose the Right Dosage of Vitamin K2

The optimal dosage of vitamin K2 depends on your age, health goals, and dietary intake. For general bone maintenance, many experts recommend 45 to 100 mcg per day of MK-7. Each soft gel of Carlson Vitamin K2 MK-7 provides 45 mcg, a well-studied amount for supporting bone health. If you are using it alongside calcium and vitamin D, 45 mcg is typically sufficient to insure proper calcium utilisation. For individuals with existing bone density concerns or those at higher risk, higher doses may be recommended under professional guidance. Always consult your health care provider before starting any new supplement, especially if you are taking blood-thinning medications or have a medical condition.

Potential Side Effects and Safety

Vitamin K2 is generally well-tolerated with a low risk of adverse effects when taken within recommended doses. The most common concerns include:

• Interactions with blood thinners: Vitamin K can counteract the effects of anticoagulants like warfarin. If you take these medications, consult your doctor before using any vitamin K supplement.
• Mild digestive upset: Some individuals may experience nausea or stomach discomfort, though this is rare.
• Allergic reactions: Those with a hypersensitivity to any ingredient in the soft gel should avoid use.

Carlson tests each batch at a registered laboratory for potency and purity, ensuring you receive a reliable, high-quality product. As with any supplement, store in a cool, dry place and keep out of reach of children. Always read the labelled and follow directions for use.

Frequently Asked Questions

Can I take vitamin K2 with vitamin D and calcium?

Yes, in fact, these three nutrients work synergistically. Vitamin D enhances calcium absorption from the gut, while vitamin K2 directs that calcium to the bones. Taking them together is common for bone health regimens.

How long does it take to see results?

Vitamin K2 levels build up over time. Studies using MK-7 show improvements in bone markers within several weeks to months, but bone density changes typically require sustained supplementation for at least one year.

Is this product suitable for vegans?

Carlson Vitamin K2 MK-7 soft gels likely contain gelatine (made from animal sources), so it may not be vegan. Check the product labelled for specific ingredients. Vegan alternatives often use plant-based capsules.

What is MenaQ7?

MenaQ7 is a patented, natural form of vitamin K2 as MK-7 derived from chickpea fermentation. It has been used in multiple clinical trials demonstrating its bioavailability and effectiveness for bone and cardiovascular health.
