Carlyle Vitamin K2 Food Supplement 100 mcg, MK-4, 240 Capsules - Non-GM & Gluten-free

Vitamin K1 vs. K2: Understanding the Difference

Many people think of vitamin K as a single nutrient, but K1 (phylloquinone) and K2 (menaquinone) have distinct functions. Vitamin K1 is found primarily in green leafy vegetables and supports normal blood clotting in the liver. Vitamin K2, on the other hand, is more bio-available in tissues outside the liver, including bones and blood vessels. MK-4, the form used in this supplement, is a short-acting K2 that requires daily intake to maintain steady levels. While K2 MK-7 (from natto) has a longer half-life, MK-4 is the form naturally produced in animal tissues and has been extensively studied for bone maintenance. Choosing between them depends on your health goals and dosage preference.

What Makes Carlyle Vitamin K2 MK-4 Different?

Vitamin K2 is an essential nutrient that your body cannot produce on its own. Unlike many supplements that uses synthetic forms, Carlyle Vitamin K2 provides 100 mcg of MK-4—a naturally occurring menaquinone form found in animal-based foods and fermented products. This quick-release capsule formula is designed for daily support, helping you maintain optimal vitamin K levels. Carlyle prioritises quality: each batch is laboratory tested for purity and potency, ensuring you receive a superior supplement. Naturally free from gluten, wheat, yeast, lactose, and artificial additives, this non-GM product fits into a variety of dietary lifestyles. Whether you're new to vitamin K2 or seeking a reliable option, Carlyle offers an honest, premium choice.

Health Benefits of Vitamin K2

Vitamin K2 contributes to normal blood clotting and the maintenance of normal bones, as recognized by the European Food Safety Authority. It activates proteins that regulate calcium distribution in the body: osteocalcin supports bone mineralisation, and matrix Gla protein (MGP) helps keep calcium in bones and out of soft tissues. By ensuring calcium is directed to the right places, K2 plays a crucial role in skeletal and vascular health. While individual results vary, consistent intake of vitamin K2 supports your body's natural processes. Many users appreciate the value and notice positive changes when incorporating this supplement into their routine.

Recommended Dosage and Usage

The recommended serving is one capsule daily, providing 100 mcg of vitamin K2 as MK-4. Since vitamin K is fat-soluble, take this supplement with a meal containing healthy fats (e.g., avocado, nuts, or olive oil) to enhance absorption. For optimal results, incorporate it alongside a balanced diet rich in calcium and vitamin D. Always follow the suggested uses on the label; do not exceed the recommended intake unless advised by a health care professional. Consistency is key—daily uses helps maintain steady MK-4 levels in your system.

How to Choose a Quality Vitamin K2 Supplement

When selecting a vitamin K2 supplement, consider the form (MK-4 vs. MK-7), dosage, and manufacturing standards. Carlyle's formula uses MK-4, which has a shorter half-life but is the form most studied for bone health. Look for third-party testing to verify purity—Carlyle laboratory tests every batch. Non-GM and gluten-free certifications ensure you avoid unwanted additives. With 240 capsules per bottle, this 100 mcg dose offers a convenient supply for over seven months, allowing you to maintain consistent daily intake without frequent reordering.

Potential Side Effects and Interactions

Vitamin K2 is generally well tolerated, with few reported side effects at recommended doses. However, it can interact with anticoagulant medications like warfarin (Coumadin). If you are on blood thinners, consult your doctor before starting any vitamin K supplement, as it may reduce the medication's effectiveness. Individuals with rare clotting disorders should also seek medical advice. As with any supplement, discontinue uses if you experience adverse reactions. Keep out of reach of children. This product is not a substitute for medical treatment or a varied diet.
