Title: Vitamin D3 + K2: Boost Immunity & Bone Health (90 Capsules)

Enhanced Text

Vitamin D deficiency is surprisingly common. Studies show that 90-95% of people have suboptimal levels. While sunlight is the primary source (Vitamin D is technically a hormone synthesized by the skin in response to sunlight), many factors—including geography, lifestyle, and skin pigmentation—limit our ability to obtain sufficient amounts. This is especially true for those living in northern latitudes or individuals who spend limited time outdoors.

Vitamin D, a fat-soluble vitamin (or hormone) stored in the body’s fat tissues and liver, plays a vital role in numerous bodily functions. Summer sun exposure often provides sufficient stores to carry us through winter, but supplementation is frequently necessary.

Key Benefits of Vitamin D3 + K2:

• Stronger Bones & Teeth: Vitamin D enhances calcium absorption, crucial for bone health, preventing osteoporosis, and maintaining healthy teeth and hair. The combination with Vitamin K2 prevents calcium from depositing in arteries and cartilage, supporting cardiovascular health. Vitamin K2 also improves calcium metabolism.
• Enhanced Immunity: Immune cells possess Vitamin D receptors, making it essential for immune function. Adequate Vitamin D levels reduce the risk of viral infections, particularly respiratory illnesses.
• Improved Mood: Vitamin D influences the production of dopamine, adrenaline, and noradrenaline, impacting mood regulation. Chronic deficiency is linked to depression.
• Natural Anti-inflammatory: Vitamin D exhibits potent natural anti-inflammatory properties.

Understanding Vitamin D:

Vitamin D exists in two forms: D3 (cholecalciferol) and D2 (ergocalciferol). Clinical research indicates D3 is the superior form for human absorption and utilization. However, efficient utilization requires conversion in the liver and kidneys into its active hormone form (calcitriol). This process depends on parathyroid hormone; therefore, thyroid issues can significantly impact Vitamin D absorption, even with high doses.

It’s crucial to remember that excessive sun exposure will cause sunburn before a Vitamin D overdose. However, overdosing from supplements is possible. High doses (5000-10000 IU) increase the risk of adverse effects. Responsible supplementation involves monitoring 25(OH)D blood levels through testing.

Recommended Vitamin D3 Levels (according to Russian Endocrine Association guidelines):

• <20 ng/mL: Deficiency (2000 IU recommended)
• 20-30 ng/mL: Insufficiency (1000-2000 IU recommended)
• 30-100 ng/mL: Normal range (supplementation unnecessary if feeling well)
• >100 ng/mL: Potential toxicity (discontinue supplementation immediately) Vitamin D isn’t easily removed from the body; cessation is crucial until levels return to normal.

Causes of Low Vitamin D Levels:

• Insufficient Sun Exposure: The most common cause.
• Kidney or Liver Issues: Impaired conversion of Vitamin D to its active form.
• Inappropriate Dosage or Supplement: Individual responses to supplements vary.
