2024's Top 9 Vitamin K2 MK4 Supplements

Find out what to look for in a quality Vitamin K2 MK4 supplement and what to watch out for

What is Vitamin K2 MK4?

Unlike its Vitamin K siblings (K1 and K2 MK7), K2 MK4 is a slightly elusive nutrient. It's found in limited dietary sources, such as grass-fed animal products, certain fermented foods, and in small amounts in some cheeses and natto (fermented soybeans). But this scarcity shouldn't belie its importance. Namely, its primary function in the body is to regulate calcium – the mineral essential for bone health and proper physiological function. Strikingly, K2 MK4 is capable of more effective utilization by the body within hours, making it a potential game-changer in health optimization.

What are the benefits of Vitamin K2 MK4?

Strengthening Bones and Preventing Osteoporosis

K2 MK4's role in bone strengthening is its most celebrated virtue. When it comes to bone health, the intricate dance of calcium deposition (into bones) and calcium removal (from soft tissues) is crucial. K2 MK4 acts as the cofactor to osteocalcin, a protein that binds calcium to the bone matrix, which in turn improves bone density and reduces the risk of fractures, particularly in the elderly. Studies have shown that K2 MK4 supplementation contributes to increasing bone mineral density, a significant metric in the fight against osteoporosis, a condition that affects millions worldwide.

Enhancing Cardiovascular Health

A deficiency in Vitamin K2 MK4 has been linked to an increased risk of arterial calcification and subsequent cardiovascular disease. By activating matrix GLA-protein (MGP), K2 MK4 assists in inhibiting the buildup of arterial calcification, thereby supporting cardiovascular health and reducing the risk of heart disease. With heart health being a significant concern for many, understanding the role of K2 MK4 in disease prevention could be life-changing for those at risk for heart-related ailments.

May Aid in Dental Health

It is also proposed that K2 MK4 might have a role in preventing or delaying dental caries and treating periodontal disease, contributing to overall oral health. This potential benefit further highlights the systemic impact that K2 MK4 can have on the human body, from bone health to cardiac function and beyond.

Are there any Side Effects?

High doses may lead to some potential reactions such as flushing, similar to the side effects observed with high-dose niacin (Vitamin B3). However, this occurs in a very small minority, and most individuals can safely supplement with K2 MK4 without these concerns. As always, we recommend that you talk to your health care professional before taking any new supplement.

  • CLINICALLY-STUDIED DOSE – You know vitamin K2 is good for your bones ... but did you know there’s more than one kind of K2? These different forms are called menaquinones. To help support bone mineral density, you’re looking for K2 menaquinone-4—about 45,000 mcg a day, to be precise. That’s the amount clinically studied to maintain healthy bone density.
  • ENCOURAGES BONE BUILDING – So why make sure you’re getting enough of this special form of vitamin K2? Because menaquinone-4 is especially good at encouraging the activity of osteoblasts—special cells that actually build your bones. Happy osteoblasts, happy bones!
  • HEALTHY BONE DENSITY – And what we mean by bones structure is the bone matrix. The bone matrix is the lattice-like support structure that makes your bones strong, and yet also flexible. Think of the scaffolding you’d see a building being built around. This kind of K2 helps osteoblasts “glue” calcium and other essential bone minerals to the bone matrix...making it stronger.
  • INGREDIENTS MATTER - Sourced using only the finest raw ingredients with the purity and potency your body deserves. The majority of our products are non-GMO, gluten-free, and manufactured in the USA—and a Certificate of Analysis is available for every product we produce.
