Core Functions and Synergistic Effects‌

‌Collagen‌

Comprises 90% of the organic matrix of bones, providing flexibility and impact resistance. Deficiency increases the risk of osteoporosis‌.
Must combine with minerals (such as calcium and phosphorus) to form a complete bone structure; calcium supplementation alone cannot replace its function‌.

‌Vitamin D3 + K2‌

‌D3 Function‌: Promotes calcium absorption in the intestines and increases blood calcium levels, but cannot regulate calcium deposition sites.

‌K2 Function (especially MK-7 type)‌:

Activates osteocalcin and matrix Gla protein (MGP) to direct blood calcium to bones, reducing the risk of vascular calcification;
Clinical studies show that when used in combination with D3, it can increase bone density and reduce fracture rates in the elderly.
‌Synergistic mechanism: D3 is responsible for “drawing calcium into the blood,” while K2 is responsible for “directing calcium into bones,” preventing misplaced calcium deposition (e.g., arterial walls).

How Collagen + D3 + K2 Work Together

Component	Primary Role
Collagen	Provides the flexible scaffold of bones (90% of organic bone matrix). Also supports skin elasticity and joint cartilage.
Vitamin D3	Promotes calcium absorption in the intestines – “brings calcium into the blood.”
Vitamin K2 (MK-7)	Activates osteocalcin and MGP – “guides calcium into bones” and supports arterial health.

Synergy: D3 increases blood calcium, K2 directs it into bone, and collagen provides the organic matrix for calcium to bind to. Together, they support bone strength, joint comfort, and skin health.

FAQ.

How long does it take to see results?

Benefit	Typical Onset Time
Skin health (hydration, elasticity)	4-8 weeks
Joint comfort	2-3 months
Bone health	>6 months (requires bone density scan)

Do I still need vitamin D3 in summer?

It depends on sun exposure. If you get 15-20 minutes of direct sunlight on arms and legs (without sunscreen) daily, you may not need supplementation. However, office workers, sunscreen users, and those in high-latitude areas may be deficient even in summer. A blood test (25-hydroxyvitamin D) is the only way to know for sure.

Are these drops suitable for vegetarians/vegans?

Standard version: Collagen is from bovine (not vegan). Vitamin D3 is typically from lanolin.
Vegan option available for OEM: We offer plant-based “collagen boosters” (amino acids + cofactors) + lichen-derived D3 + vegan K2. Please specify when ordering.

Are there any side effects or interactions?

At recommended doses, most people tolerate well. Important: Vitamin K2 may interact with anticoagulants (e.g., warfarin). Consult your doctor before use if you take blood thinners.
