Naturalis Vegan Vitamin D3+K2 from Algae | 5000 IU D3 with 120 mcg MK-7 | Vegan Society Certified | 180 Softgels

Frequently Asked Questions

Can I take vitamin D3 and K2 together?

Absolutely. In fact, taking them together is recommended for optimal calcium utilisation. Many nutrition experts suggest combining them for synergistic benefits.*

What is the best time to take D3 and K2?

Since D3 and K2 are fat-soluble vitamins, taking them with a meal containing fat improves absorption. The organic extra virgin olive oil in Naturalis softgels helps with this. Many people take them with breakfast or lunch.

Are there any side effects?

When taken as directed, vitamin D3 and K2 are generally well tolerated. If you take blood thinners like warfarin (Coumadin), consult your health care provider before taking vitamin K2.

Is this product suitable for vegans?

Yes, Naturalis Vegan Vitamin D3+K2 is Vegan Society certified. The D3 comes from algae, the K2 from natto, and the soft gel capsule is vegetable-based (carrageenan-free).

What to Look For in a D3 + K2 Supplement

Not all D3 and K2 supplements are created equal. Here's what to consider when choosing:

• Form of Vitamin D: Look for naturally sourced D3 (cholecalciferol) rather than D2 (ergocalciferol), as D3 is more effective at raising and maintaining blood levels. Naturalis uses D3 from Nannochloropsis oceanica microalgae, a sustainable vegan source.
• Form of Vitamin K2: MK-7 is preferred over MK-4 due to its longer half-life and once-daily convenience. MK-7 from natto is well-researched. Naturalis provides 120 mcg of natto-based MK-7 per soft gel capsule.
• Dosage Ratio: A typical effective ratio is 5000 IU D3 to 100–120 mcg K2 (MK-7). This matches the 5000 IU D3 and 120 mcg K2 in each Naturalis soft gel capsule.
• Purity & Testing: Choose products that are non-GM, gluten-free, and manufactured in a GMP certified facility. Naturalis is Vegan Society certified and made in California.
• Delivery Format: Liquid softgels in organic extra virgin olive oil enhance absorption. The softgels are carrageenan-free and suitable for vegans.

Why Take Vitamin D3 and K2 Together?

Vitamin D3 and vitamin K2 work as a team to support your body's calcium balance. Vitamin D3 helps your body absorb calcium from food, while vitamin K2 helps direct that calcium to your bones and teeth — and supports normal blood coagulation.* This synergy makes the combination important for maintaining strong bones and healthy teeth.*

Many people take vitamin D3 alone, but without enough K2, calcium may not end up where it is needed most. That's why a combined supplement like Naturalis Vegan Vitamin D3+K2 offers a more complete approach to bone and immune support.*

Key Health Benefits

• Bone Health: Supports calcium absorption and bone mineralisation, helping maintain strong and healthy bones as you age.*
• Immune Support: Vitamin D3 is known to contribute to normal immune function, helping your body defend against seasonal challenges.*
• Blood Clotting & Bone Maintenance: Vitamin K2 contributes to normal blood coagulation and maintenance of normal bones.*
• Teeth & Joints: Healthy calcium balance also contributes to strong teeth and comfortable joint function.*

These benefits are especially valuable for those following a plant-based diet, as vitamin D3 from lanolin (common in many supplements) is not vegan. Naturalis offers a truly vegan alternative without sacrificing quality or potency.*

Understanding the Synergy: How D3 and K2 Work Together

When you consume calcium, vitamin D3 (cholecalciferol) stimulates the production of calcium-binding proteins in the gut, enhancing absorption.* Once calcium enters the bloodstream, vitamin K2 (menaquinone) activates two key proteins: osteocalcin, which helps bind calcium to the bone matrix, and matrix GLA protein (MGP), which supports normal blood coagulation.*

This complementary action means D3 and K2 are better together. Without K2, calcium absorbed thanks to D3 may circulate without proper direction. Without D3, K2 has less calcium to work with. The result? A balanced internal environment that supports bone density, normal blood clotting, and overall wellness.*

Naturalis uses the most bio-available forms: cholecalciferol from microalgae (D3) and menaquinone-7 (MK-7) from natto. MK-7 has a longer half-life than MK-4, providing steady support throughout the day.*

Recommended Dosage

Take one (1) liquid soft gel capsule daily with food. Each soft gel capsule delivers 5000 IU (125 mcg) of vitamin D3 and 120 mcg of vitamin K2 (MK-7). This dosage is suitable for adults looking to support bone and immune health.* Pregnant or nursing women, and those with medical conditions, should consult a health care professional before uses.
