What Vitamin D3/K2 Does for Your Body

Corrects Vitamin D Deficiency†
Therapeutic 10,000 IU dose provides the potency needed to restore optimal vitamin D levels, especially critical for those with limited sun exposure, darker skin tones, or absorption challenges.†

Builds Stronger Bones†
D3 enhances calcium absorption while K2 activates osteocalcin, the protein that binds calcium into bone matrix, working together to support bone density and reduce fracture risk.†

Protects Cardiovascular Health†
K2 acts as your "calcium traffic cop," directing calcium to bones and teeth while keeping it away from arteries and soft tissues where it could cause problems.†

Supports Immune Function and Mood†
Vitamin D plays a critical role in immune system regulation and neurotransmitter production, helping support your body's natural defenses and promoting positive mood.†

Key Ingredients

D3 and K2 work together as nature intended—one helps absorb calcium, the other directs it to the right places.

The "sunshine vitamin" in its most bioavailable form. D3 facilitates calcium absorption from the digestive tract into the bloodstream and plays a critical role in bone mineralization, immune system regulation, mood support, and overall cellular health. This therapeutic dose corrects deficiency rather than just maintaining minimal levels.†

This therapeutic dose corrects deficiency rather than just maintaining minimal levels.†

The essential cofactor that activates proteins (osteocalcin and matrix GLA protein) to direct calcium to bones and teeth while preventing calcium deposits in arteries and soft tissues. Without adequate K2, even optimal D3 levels cannot ensure proper calcium metabolism. The MK-7 form provides superior absorption and longer activity.†

Frequently Asked Questions

What is the optimal level of vitamin D?

Optimal levels of vitamin D have been hotly contested for decades, with “normal” being described by many physicians as anything above 30ng/dl. We recommend speaking to your qualified healthcare provider to find out what level is best for you based on your age, weight, and health history.

How can I find out my vitamin D levels?

If you’d like to have your vitamin D levels checked, all it requires is a simple and inexpensive blood test. Many doctors will order this test for you if you ask them to, and it is especially important to monitor your levels when you are taking higher amounts in an effort to raise your vitamin D to optimal levels.

When is the best time of day to take Vitamin D3/K2? Should it be taken with or without food?

Vitamin D3/K2 can be taken at any time of the day, morning or evening. Vitamin D3/K2 should always be taken with meals if possible as both vitamin D3 and vitamin K2 are fat soluble, and taking the formula with a meal will greatly improve its absorption.

Is Dr. Myers’ Vitamin D3/K2 Liquid safe for pregnant women and breastfeeding mothers?

Vitamin D3/K2 is safe to take while pregnant or nursing when used as directed, provided you have spoken to your physician first to ensure that you are not taking any prescriptions that may be contraindicated (especially blood thinners), or should not take it for any other reason. Keep in mind it is important to monitor blood levels when taking vitamin D longterm.

Fermented Foods To Avoid With Candida Overgrowth
In my many years of treating patients for Candida overgrowth, I saw a surprising number of people who were surprised to learn that eating fermented foods could actually be making their condition worse. That’s probably because a number of Candida treatment plans suggest adding fermented foods to your diet to feed the good bacteria in your gut.

What Are the Signs Leaky Gut Is Healing?
Leaky gut occurs when the intestinal lining becomes compromised, allowing toxins and undigested food particles to enter the bloodstream. This potentially leads to inflammation, digestive issues, and autoimmune conditions. Healing leaky gut involves following a comprehensive protocol to remove irritants, restore essential nutrients, reinoculate with probiotics, and repair the gut lining with targeted supplements like Leaky Gut Revive® and collagen. Learn more about the signs leaky gut is healing.

Are Sugar Alcohols Bad For You?
Sugar alcohols, such as erythritol, xylitol, sorbitol, and maltitol, are low-calorie sweeteners often found in packaged foods. While they can support low-carb diets and dental health, they are heavily processed and may cause digestive issues like bloating, gas, and diarrhea. If you suffer from conditions like Candida overgrowth, leaky gut, or SIBO, sugar alcohols can worsen symptoms by feeding harmful bacteria. Though they are a lower-calorie alternative to sugar, they can still impact blood sugar levels and gut health. To repair gut damage caused by sugar alcohols, consider following a gut-healing protocol like the 4R approach with tools such as Gut ImmunIG™.
