Question: 1 / 645

Which micronutrient is crucial for bone formation and muscle repair?

Vitamin C

Vitamin D

The correct answer, Vitamin D, plays an essential role in the body's ability to absorb calcium, which is vital for bone formation and health. Vitamin D facilitates the intestinal absorption of calcium, ensuring that bones receive sufficient mineralization to maintain their density and strength. Additionally, Vitamin D contributes to muscle function and repair by enhancing muscle strength and promoting recovery after exercise. This makes it a crucial nutrient not only for bone health but also for supporting overall physical performance and recovery.

While calcium is indeed critical for bone structure, Vitamin D is equally important as it regulates calcium levels in the bloodstream. Without adequate Vitamin D, the body struggles to utilize calcium effectively, leading to weaker bones and potentially affecting muscle repair.
