Vitamin D3+K2 by PRL: Bone, Calcium, Heart and Immune Support

When I talk with clients about foundational nutrients, vitamin D almost always comes up. And for good reason. Vitamin D does far more than support bones. It plays a role in immune balance, cardiovascular health, and how the body uses calcium.

That is why I often recommend Vitamin D3+K2 Premier from Premier Research Labs. This formula pairs two essential vitamins that work best together, not alone. It is clean, plant based, and thoughtfully dosed for real clinical support.

Let me walk you through why this combination matters and how it supports whole body health.

What Is Vitamin D3+K2 Premier?

Vitamin D3+K2 Premier is a two-in-one supplement that supports how the body absorbs, uses, and directs calcium.

• Vitamin D3 helps your body absorb calcium and phosphorus from food

• Vitamin K2 helps guide that calcium into bones and teeth, not into arteries or soft tissue

This formula uses clinically relevant doses in a single capsule and delivers both vitamins in highly bioavailable, plant-based forms.

Why Vitamin D3 and K2 Belong Together

Vitamin D3 increases calcium absorption. That is essential, but it is only part of the picture.

Vitamin K2 activates proteins that tell calcium where to go. Without enough K2, calcium can end up in places you do not want it, like blood vessels.

When combined, these two vitamins support:

• Strong bones and proper mineralization

• Healthy calcium metabolism

• Cardiovascular and vascular health

• Balanced immune function

This is why pairing D3 with K2 matters so much, especially at higher D3 intake levels.

Key Health Benefits

Bone Strength and Formation

Vitamin D3 supports calcium and phosphorus absorption. Vitamin K2 supports bone formation and mineral density. Together, they help maintain strong, resilient bones over time.

Cardiovascular and Vascular Health

Vitamin K2 supports healthy arterial blood flow and vascular elasticity by helping keep calcium out of arteries. This is especially important as we age.

Immune System Support

Vitamin D3 plays a role in immune regulation and resilience, especially during seasonal challenges or periods of low sun exposure.

Calcium Balance and Utilization

This formula supports proper calcium metabolism so the mineral is absorbed efficiently and used appropriately throughout the body.

Clinically Relevant, Clean Formula

Each capsule provides:

• Vitamin D3 (as Vitashine®), 125 mcg (5,000 IU)

• Vitamin K2 (as menaquinone MK-7), 180 mcg

These are clinically established dosages, not trace amounts.

The formula also includes:

• Organic extra virgin olive oil to enhance absorption

• Plant-source vitamin E as a natural preservative

• Plant-source capsule made from cellulose and water

This supplement is:

• Plant based and vegan friendly

• Gluten free

Where These Vitamins Come From

• Vitamin D3 is sourced from Vitashine®, a plant-based, lichen-derived form suitable for vegetarians and vegans

• Vitamin K2 is derived from fermented natto and provided as MK-7, the most researched and bioavailable form

These sources were selected for absorption, transport, and stability in the body.

Who May Benefit Most

I often see this formula used by people who:

• Get limited sun exposure

• Are concerned about bone density

• Want cardiovascular support alongside calcium intake

• Prefer clean, plant-based supplements

• Are increasing vitamin D intake and want proper calcium balance

As always, individual needs vary, and guidance matters.

Dosage and How to Take It

• Take 1 capsule daily

• Take with a meal that contains fat for best absorption

• Follow the guidance of your healthcare professional if personalized dosing is recommended

Do not exceed recommended intake unless directed by a qualified provider.
