## Overview

Life Extension Mega Vitamin K2 delivers a clinically studied 45 mg dose of menaquinone-4 to support healthy bone density and structure. This high-potency, non-GMO, gluten-free formula activates bone-building cells and promotes long-term bone health, making it an essential daily supplement for those seeking to maintain strong bones with trusted quality and purity.

## Description

Mega Vitamin K2 is a high-potency formula for bone health. It contains 45,000 mcg of vitamin K2 as menaquinone-4, a dosage clinically studied to help maintain strong, healthy bones in populations that need it most, such as postmenopausal women. Mega Vitamin K2 contains 30 gluten-free capsules, enough for a 1-month supply. This formula is made with 100% non-GMO ingredients.

Review: excellent product - I heard that supplementing with vitamin K2 in the form of MK4 is very effective for bones and vascular endothelial plaque, so I bought this product with a high concentration. I hope it works. I'll leave a follow-up review later.
Review: Great to take with calcium - I've been using this product for 3 months now and have found that it has helped my calcium absorption a little. It's a thin capsule that is easy to swallow and only requires 1 pill per day. An easy addition to your vitamin regimen. I consulted with my doctor before I started taking it, and I recommend you do the same to make sure it does not conflict with any medications you are taking.

## Features

- Encourages healthy bone structure – Vitamin K2 supports the activity of osteoblasts: specialized cells that help build your bones, and are necessary for healthy bone structure and growth.
- Promotes healthy bone mineral density – Over time, bones go through a growth phase, followed by remodeling and upkeep. But this process declines with age, impacting bone mineral density. Vitamin K2 in the right doses can help maintain healthy bone density.
- Clinically studied dose – This formula delivers 45,000 mcg (45 mg) of vitamin K2 (menaquinone-4), a clinically studied dose shown to be effective for those who need that support the most.
- ngredients matter – We use the finest raw ingredients with the quality and purity you deserve. The majority of our products are non-GMO, gluten-free and manufactured in the USA—and a Certificate of Analysis is available for every one.
- Live your healthiest life – We believe the answers to a healthier life are in reach, and that scientific research is the key to getting there. That’s why so many of our formulas feature specific ingredients and amounts based on scientific studies.
