Carlson Vitamin D3 + K2, 2000 IU (50 mcg) with 90 mcg Vitamin K2 MK-7, 60 Capsules

Key Health Benefits

Carlson Vitamin D3 + K2 provides a potent combination of two fat-soluble nutrients that work together to support your body's calcium metabolism and overall wellbeing. Each capsule delivers 50 mcg (2,000 IU) of vitamin D3 and 90 mcg of vitamin K2 as MK-7, the most bioavailable form of K2. This synergy helps maintain strong bones, healthy teeth, and cardiovascular function. Additionally, vitamin D3 supports normal immune cell function, while vitamin K2 promotes arterial flexibility by activating matrix GLA protein, which helps prevent calcium deposits in blood vessels. Together, they contribute to optimal vitality and energy metabolism.

Understanding the Synergy: How Vitamin D3 and K2 Work Together

Vitamin D3 (cholecalciferol) is a hormone precursor that increases calcium absorption from the digestive tract. However, absorbing calcium is only half the equation—the body needs to direct that calcium to the right places. Vitamin K2, specifically as menaquinone-7 (MK-7), activates osteocalcin to bind calcium to bone matrix, and matrix GLA protein to keep calcium out of soft tissues like arteries. This partnership ensures that the calcium brought in by D3 is optimally utilised. The MK-7 form used by Carlson has a longer half-life than MK-4, providing sustained support throughout the day.

Why Take Vitamin D3 and K2 Together?

Many people supplement with vitamin D3 alone, but without adequate K2, calcium may end up deposited in unwanted areas. Taking both together ensures you get the full benefit of each nutrient working in concert. Carlson’s combination product offers a convenient way to support bone density, dental health, and cardiovascular wellbeing. Each capsule provides a balanced ratio of 2,000 IU D3 to 90 mcg K2, a formulation that aligns with current nutritional research. It is non-GM, Gluten Free, and free from artificial preservatives, making it suitable for most dietary needs.

What to Look For in a D3 + K2 Supplement

Not all D3 and K2 supplements are created equal. When choosing, consider the form of vitamin K2: MK-7 is preferred for its prolonged activity. Carlson uses MK-7 derived from natto (fermented soy). Also check the dosage ratio—2,000 IU D3 with 90–100 mcg K2 is commonly recommended. Purity matters: Carlson’s capsules are third-party tested by an FDA-registered laboratory—though in Australia, look for TGA-listed products if available. The product is also certified non-GM and Gluten Free.

Frequently Asked Questions

Can I take vitamin D3 and K2 separately?
Yes, but taking them together in one capsule ensures you receive the synergistic benefit without missing a dose. It’s also more convenient.

What is the best time to take D3 and K2?
Because both are fat-soluble, take them with a meal containing healthy fats for optimal absorption. Many people choose breakfast or lunch.

Are there any interactions with medications?
If you are taking anticoagulants (e.g., warfarin), consult your healthcare professional before adding vitamin K2, as it may affect blood clotting. High vitamin D doses should be monitored if you have kidney issues.

How long does one bottle last?
With 60 capsules, taking one daily provides a two-month supply.

Recommended Dosage

The suggested use is one capsule daily, or as directed by your healthcare professional. Each capsule provides 50 mcg (2,000 IU) of vitamin D3 and 90 mcg of vitamin K2 as MK-7. This dosage suits most adults aiming to support bone health, immune function, and calcium metabolism. As with any supplement, it is wise to consult a practitioner to determine your individual needs.
