Vitamin D works harmoniously with vitamin K in the body*

Vitamin D is a key player in supporting bone, heart, immune, and brain health, and calcium regulation.* Vitamin K also supports bone and heart health and helps transport calcium into our bones and teeth and away from the arteries.* Geranylgeraniol (GG) further supports bone strength.*

Vitamin D Synergy™ is a maintenance vitamin D formula by Designs for Health.* Per capsule, it provides 2,000 IU of vitamin D3 along with 2,000 mcg of vitamin K (as K1 and K2) and 5 mg of geranylgeraniol (GG-Gold®), a compound that supports the body’s natural vitamin K2 production per capsule.* It supports bone health, cardiovascular function, and healthy immune balance.*

Vitamin D Synergy™ is formulated to help maintain optimal vitamin D status for individuals who already have adequate status.* Its 2,000 IU serving is ideal for long-term daily maintenance rather than repletion.* Individual results may vary based on sun exposure, diet, and current vitamin D levels.*

Key benefits include support for optimal bone health, cardiovascular function, arterial strength and elasticity, healthy immune balance, and proper calcium utilization.* These benefits are supported by the synergistic combination of vitamin D3, vitamin K1, vitamin K2 (as MK-4), and geranylgeraniol (GG-Gold®), a compound that supports the body’s natural vitamin K2 production.*

Take one capsule per day with a meal, or as directed by your healthcare practitioner. Taking with food supports absorption of fat-soluble vitamins. Consult your practitioner before use if you are taking Coumadin, warfarin, or other blood-thinning medications.

Per serving, Vitamin D Synergy™ contains 2,000 IU of vitamin D3 (cholecalciferol) for immune and calcium support, 1,000 mcg of vitamin K1 to promote healthy blood clotting, 1,000 mcg of vitamin K2 (as MK-4) to support bone and arterial health, and 5 mg of GG-Gold®, a source of geranylgeraniol, to support the body's natural K2 production.*

You may maintain healthy vitamin D status and experience ongoing support for bone strength, immune resilience, and well-being.* This maintenance formula is designed for individuals who already have adequate vitamin D status.* Results depend on baseline status, sun exposure, and practitioner guidance.*

Vitamin D Synergy™ is designed for daily use when taken as directed.* It is gluten-free, dairy-free, soy-free, and non-GMO.* Consult your healthcare practitioner before use if you are pregnant, nursing, taking blood-thinning medications, or managing a health condition.*

Vitamin D Synergy™ provides 2,000 IU of D3 for daily maintenance, while Vitamin D Supreme provides 5,000 IU for higher-serving needs or repletion.* Both include the same synergistic vitamins K1, K2, and GG-Gold®, a source of geranylgeraniol.* Your practitioner can help determine which serving size is appropriate based on vitamin D status.*
