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).

Recommended population

People at high risk of osteoporosis (such as postmenopausal women and the elderly)

People with insufficient sun exposure and diets lacking in vitamin D/K (such as vegetarians)

Adolescents who need support for bone development

How to choose high-quality collagen and vitamin D3/K2 drops

‌1. Key Points for Choosing Collagen‌

‌Safety First‌: Ensure the product has authoritative quality inspection reports, contains no hormones or harmful additives, and avoids adverse reactions.

‌Molecular Weight and Absorption‌: Preferably choose low-molecular-weight collagen peptides (molecular weight <1500 Da), as these products are easier for the human body to absorb and produce more significant effects.

‌Adequate Dosage: Daily intake is recommended at 5,000–10,000 mg to meet the needs of bones and skin; lower doses may be ineffective.  

‌Type Matching: Select collagen types based on specific needs:  

Type I Collagen (accounting for 90% of the human body): Targets skin firmness and bone flexibility, suitable for anti-aging and bone health.

Type III collagen: Supports skin elasticity and vascular support, and can be combined with Type I for enhanced overall effects.

Raw material sources: Choose brands with clear certifications and high知名度, such as German Gelita, French DuPont, or Japanese Nippi, and avoid products from small manufacturers with unclear sources.

II. Key considerations for selecting Vitamin D3/K2 drops

D3 dosage control: The safe daily dosage for adults is 800–4,000 IU; 800–2,000 IU is recommended for maintaining bone health, and the dosage can be temporarily increased to 5,000–10,000 IU in cases of deficiency, but blood calcium levels should be monitored regularly to prevent overdose.

‌K2 Type and Dosage: Preferably choose vitamin K2 in the MK-7 form (higher bioavailability), with a daily dose of 90–180 μg, which effectively directs calcium deposition into bones and reduces the risk of vascular calcification.

Synergistic Formula Advantages: Choose a liquid form (dissolved in MCT oil such as coconut oil), which has higher bioavailability than tablets; combining D3 and K2 can achieve a synergistic effect of “directing calcium into the bloodstream and guiding it into the bones.”

Contraindications: Avoid K2 if taking anticoagulants (such as warfarin), as it may interfere with blood clotting; elderly individuals should assess kidney function to prevent hypercalcemia.
