What Makes Vitamin D Synergy Different?

This formula combines three key nutrients: vitamin D3 (cholecalciferol), the form naturally produced by sun exposure; vitamin K1 from leafy greens; and vitamin K2 (menaquinone-7), which works synergistically with D. Vitamin D helps the body absorb calcium, while K directs calcium to bones and away from soft tissues. This dual-action approach supports both strong bones and arterial health.*

Key Benefits of Vitamin D with K

Bone Health: Vitamin D contributes to normal calcium absorption and bone mineralization. Vitamin K supports bone matrix proteins, helping maintain bone density.*
Immune Support: Vitamin D plays a role in the normal function of the immune system, helping your body maintain proper defences.*
Healthy Mood: By supporting brain health and neurotransmitter function, vitamin D helps promote a positive mood and emotional balance.*
Arterial Health: Vitamin K helps prevent calcium buildup in arteries, promoting cardiovascular wellness.*

Optimize Your Bone, Immune, and Mood Health Naturally

Getting enough vitamin D can be a challenge, especially during Canadian winters when sunlight is scarce. Designs for Health Vitamin D Synergy offers 2000 IU of biologically active vitamin D3, paired with vitamins K1 and K2 to enhance absorption and target multiple systems. This carefully crafted supplement supports bone health, immune function, and a healthy mood — all in one convenient capsule.*

Who Should Take This Supplement?

Individuals with limited sun exposure, darker skin tones, or those over 50 may benefit from additional vitamin D. Adults following a busy indoor lifestyle or living in northern latitudes often need supplementation. This product is also ideal for those seeking combined D and K support in one formula. Always consult a healthcare professional before starting any new supplement.

How to Use Vitamin D Synergy

Each serving is one capsule providing 2000 IU (50 mcg) of vitamin D3 and 2000 mcg of a vitamin K blend (K1 and K2). For optimal absorption, take with a meal containing fat. This 120-capsule bottle provides a four-month supply when taken at the recommended daily dose. Store in a cool, dry place.

Safety and Considerations
