OstroVit Vitamin D3 5000 IU 

High-potency sunshine vitamin for bone strength, immunity, and vitality

What it is:

OstroVit Vitamin D3 5000 IU is a premium supplement providing 125 μg (5000 IU) of cholecalciferol per capsule—a highly absorbable form of vitamin D3. Known as the “sunshine vitamin,” D3 supports bone mineralization, calcium balance, muscle function, and immunity. This extra-strong formula is especially valuable in autumn and winter, when sunlight exposure is limited.

Key Benefits:

• 125 μg (5000 IU) Vitamin D3 per serving

• Supports calcium and phosphorus absorption for healthy bones and teeth

• Promotes normal muscle function and immune system activity

• Plays a role in cell division and metabolic balance

• May help maintain healthy testosterone levels in men

Why it works:

Vitamin D3 is essential for maintaining skeletal strength, immune defense, and muscle performance. It regulates calcium and phosphorus metabolism, preventing deficiencies that can lead to weak bones, fatigue, and lowered immunity. Research also suggests that adequate vitamin D3 may help support healthy hormone levels, adding to overall vitality and wellness. OstroVit’s high-dose 5000 IU formula ensures that your daily needs are more than covered, even in low-sunlight seasons.

Who it’s for:

• People with low sun exposure (especially in autumn and winter)
