The science behind the support

Vitamin D3 + K2 works behind the scenes to support several key systems that keep you feeling balanced, especially when daylight is limited.

From immune signaling to calcium absorption and mood regulation, this duo helps your body stay nourished and functioning at its best. Here’s how each nutrient plays its part.

Vitamin D3 increases calcium absorption in the gut, while K2 helps direct calcium into bones. Together, they support bone strength and long-term skeletal health.*

Vitamin D helps activate key immune cells that keep your immune system responsive and balanced. It plays a role in how your body recognizes and responds to everyday stressors,especially helpful during seasons with limited sunlight.

Vitamin D supports the production of serotonin, a neurotransmitter tied to mood regulation and emotional balance, especially relevant during months with reduced daylight.

By supporting immune function, calcium utilization, and overall nutrient signaling, Vitamin D3 + K2 contributes to steadier, more consistent daily energy.

K2 helps guide calcium into bones and away from soft tissues, supporting healthy arterial function and circulatory well-being.*

Why You Want D3 + K Together

For calcium to truly support your body, two steps have to happen: you need to absorb it, and you need to use it correctly.

D3 Helps You Absorb Calcium D3 Helps You Absorb CalciumMost people don’t realize that vitamin D3 is what allows your body to absorb calcium. When D3 is low, calcium absorption drops and your body cannot fully use the mineral it needs for strong, healthy bones.
K Helps Direct Calcium Where It’s Needed K Helps Direct Calcium Where It’s NeededOnce calcium is absorbed, vitamin K activates proteins that help guide it into bones and away from soft tissues. This supports healthy calcium placement and contributes to stronger bones over time.*
Two Forms of K = More Complete Support Two Forms of K = More Complete SupportWe use both K2 and K1 because they play different roles in calcium balance. K2 supports the long-term process of moving calcium into bones, while K1 helps with your body’s everyday calcium activity.

Vitamin D3 is the more bioavailable form, meaning your body absorbs and uses it more efficiently than D2. D3 is also the form your body naturally produces when exposed to sunlight, making it the preferred choice for supplementation.

Even with sunlight exposure, many people don’t produce enough Vitamin D, especially in colder months or if you wear sunscreen. Our D3+K2 helps maintain optimal levels of Vitamin D year-round, and K2 ensures the calcium is properly managed.

Yes, D3 is known to support mood and energy levels, especially in people who are deficient. It’s often referred to as the "sunshine vitamin" due to its positive effects on mental health, and K2 complements this by supporting overall wellness.

Low levels of Vitamin D have been linked to increased aging, immune dysfunction, increased inflammation, brain dysfunction, reduced serotonin, reduced nerve growth factor, reduced T Cells, weaker bones, learning impairments, increased depression, and increased DNA damage.
