Vitamin D3 on its own is only half the story. Sandhus Vitamin D3K2 pairs it with essential nutrients that helps guide, activate, and regulate vitamin D3 in your body.

What makes it stands out:
• K2 (MK-7) works with Vitamin D3 to support proper calcium utilization, helping direct it to the bones rather than soft tissues
• Magnesium is required for D3 activation and helps reduce the risk of calcium imbalances or bone loss.
• Zinc supports D3 signaling at the cellular level and aids in immune response.
• Quercetin assists with zinc delivery and helps ease oxidative stress.

Most people are unknowingly deficient in the cofactors needed for D3 to work. This formula gives you everything in one smart, bioavailable blend.

Sandhus vitamin D3K2 takes a multi-targeted approach to wellness by nourishing your body at the root level-from bone density to cardiovascular balance and immune resilience.

Here’s how it works:
• Vitamin D3 aids in calcium absorption in the intestines, supporting stronger bones and healthy calcium levels.
• Vitamin K2 (MK-7) helps activate proteins like osteocalcin and matrix GLA, which guide calcium away from soft tissues and into bone, supporting arterial flexibility.
• Magnesium plays a vital role in converting D3 into its active form (calcitriol), and helps regulate parathyroid hormone (PTH), which assists in calcium balance.
• Zinc supports vitamin D receptor (VDR) activity, helping your cells respond more efficiently to D3. It also aids in immune cell function and tissue repair.
• Quercetin supports immune health by transporting zinc into cells, providing healthy cytokine signaling.

Together, these nutrients create a comprehensive formula that supports bones, heart, and immune health - all from a single daily dose.

Yes. If you are indoors often or live in low-light climates, Sandhus Vitamin D3K2 is ideal for maintaining healthy mood, energy, and immune strength.

Why it works during low sun exposure:
• Delivers 5000 IU of D3 per serving an optimal daily dose for restoring D levels in people who don’t get enough sun.
• Includes Magnesium and B6 to support the production of key neurotransmitters like serotonin and melatonin, which help regulate mood, sleep quality, and circadian rhythm.
• Helps reduce winter-related fatigue, low mood, and immune vulnerability.
• Targets root-level deficiencies that often go unnoticed during colder months.

An estimated 42% of U.S. adults are vitamin D deficient, especially during the winter months. Sandhus Vitamin D3K2 is thoughtfully formulated to help maintain optimal levels and support year-round wellness.

Quercetin is a plant-based antioxidant that aids in the immune and cellular support provided by Sandhus Vitamin D3K2.

Its key functions include:
• Acts as a zinc ionophore, helping zinc enter cells where it supports healthy immune response.
• Aids in cytokine activity, helping your body maintain immune balance during stress.
• Helps calm mast cells, easing histamine-driven allergic response.
• Supports the body’s natural antioxidant activity, helping the cells from oxidative stress.

When combined with zinc and D3, Quercetin completes a trio of immune health support—working from the inside out.

Here’s why it’s daily-friendly:
• Provides 5000 IU of D3, within the Endocrine Society’s safe upper limit for most adults.
• Includes Vitamin K2, which helps prevent calcium buildup in arteries during extended D3 use.
• Magnesium, Zinc and Vitamin B6 support vital enzymatic metabolism and absorption.
• Supports long term bone density, mood, cardiovascular wellness, and immune health.

It’s not just about taking Vitamin D3. It’s about taking it with the right nutrients and this formula delivers exactly that.
