Comprehensive support thanks to vitamins D3 and K2
BrainMax Vitamin D3 & K2 combines two key micronutrients – vitamin D3 and vitamin K2 (MK-7) – along with organic turmeric for daily nourishment and protection of the bone system. Vitamin D3 supports normal absorption of calcium and phosphorus, contributing to the maintenance of strong and healthy bones.
Vitamin K2 (MK-7) aids proper blood clotting and ensures that calcium is deposited in the bones, not in the arteries.
Organic turmeric complements the mixture's effect with its natural antioxidant properties.
Vitamin D3 and its health impact
- Contributes to normal immune system function
- Helps maintain normal bone condition
- Supports proper muscle function
- Contributes to normal tooth condition
- Involved in the cell division process
- Aids calcium and phosphorus absorption and utilisation
- Supports maintaining normal blood calcium levels
Population and vitamin D3 levels
According to a comprehensive international study published in the Annals of the New York Academy of Sciences¹, nearly half the population has vitamin D levels below 50 nmol/L – especially during the winter months.
Lower values are more common in people:
• with limited sun exposure,
• older individuals,
• or those who spend most of their time indoors.
Lack of sunlight is therefore the main reason why vitamin D3 has become one of the most recommended dietary supplements, especially in periods of low sunlight intensity.
