Detailed Benefits of Vitamins D3 & K2, 5,000 IU / 100 mcg, Life Extension

• Support for Bone and Teeth Health Through D3 + K2 Synergy

One of the most important roles of vitamin D3 is to facilitate calcium and phosphorus absorption from the digestive tract. However, for this calcium to reach where it should – in bones and teeth – vitamin K is needed, especially K2 forms, which participate in activating proteins involved in calcium fixation in bone tissue.

By associating vitamin D3 with K1, K2 (MK-4 and MK-7), this formula can:
✅ Support efficient calcium absorption and utilization in the body
✅ Contribute to maintaining bone density and structural bone resistance
✅ Support teeth health, in the context of proper oral hygiene and adequate nutrition

This synergy transforms calcium from a simple circulating mineral into a structural element properly integrated into the bone matrix.

• Cardiovascular Protection Through Correct Calcium Direction

Adequate vitamin K2 intake is important not only for bones, but also for the cardiovascular system. Vitamin K-dependent proteins help maintain healthy calcium balance in the body, supporting its deposition in bones and reducing the risk of unwanted accumulation in vascular walls.

Vitamins D3 & K2, Life Extension offers a complete vitamin K complex:
✅ Vitamin K1 – predominantly involved in normal blood clotting
✅ Vitamin K2 (MK-4) – fast-acting form, naturally present in some animal foods
✅ Vitamin K2 (MK-7 trans) – form with longer half-life, which supports prolonged action in the body

Through this combination, the product can support:
✅ Maintaining a healthy vascular system
✅ Optimal calcium balance between bones and soft tissues
✅ General cardiovascular system protection, in the context of a balanced lifestyle

• Support for Immune System and Body Resilience

Vitamin D3 is known for its essential role in normal immune system functioning. Vitamin D receptors are present in numerous immune system cells, and adequate vitamin D level contributes to balanced immune response.

Vitamins D3 & K2, 5,000 IU / 100 mcg can:
✅ Support the body's natural defense
✅ Contribute to immune mechanism efficiency in the face of daily challenges
✅ Help the body maintain resilience during demanding periods

When immunity is supported, the body adapts better to seasonal changes, stress and other environmental factors.

• Support for Normal Thyroid Functioning Through Sea-Iodine™ Iodine

Besides vitamins D3 and K, the product includes 1,000 mcg iodine from Sea-Iodine™ complex, obtained from organic kelp and bladderwrack extracts, enriched with potassium iodide. Iodine is essential for thyroid hormone synthesis (T3 and T4), which regulate metabolism, body temperature, energy level and numerous metabolic processes.

Through iodine intake, Vitamins D3 & K2, Life Extension can:
✅ Support normal thyroid gland functioning
✅ Contribute to balanced energy metabolism
✅ Help maintain optimal vitality level, in the context of adequate nutrition

Combining thyroid support (iodine) with bone and cardiovascular support (D3 + K2) transforms this supplement into a complete formula for the metabolism-energy-structure axis.

• Support for Energy Metabolism and Energy Level

Thyroid hormones influence how the body uses nutrients to produce energy. Vitamin D3, in turn, is involved in general vitality state and muscle function. By associating D3 with iodine, the formula supports both energy production and its efficient use in tissues.

Vitamins D3 & K2, 5,000 IU / 100 mcg can:
✅ Support normal metabolic rate
✅ Contribute to reducing fatigue sensation associated with micronutrient intake imbalances
✅ Help maintain pleasant general tone and daily effort capacity

• Support for Muscle Function and Mineral Balance

Vitamin D contributes to normal muscle functioning, influencing how calcium is used at muscle level. When D3 and K2 work together, calcium is better managed between bones, teeth and musculature, supporting strength and coordination.

The supplement can:
✅ Support normal muscle contractility
✅ Contribute to muscle comfort in day-to-day activities
✅ Help maintain good coordination and stability through support offered to bones and muscles

• Support for General Health and Functional Longevity

Through its impact on bones, teeth, cardiovascular system, immunity, thyroid, metabolism and musculature, Vitamins D3 & K2, Life Extension offers global support for the body. A strong skeleton, healthy blood vessels, balanced metabolism and functional immune system are basic elements for maintaining an active and independent life.

The product can:
✅ Contribute to maintaining optimal structure and function of the osteoarticular system
✅ Support vascular protection and mineral balance
✅ Help support a stable state of well-being, both physical and general
