Vitamin D has numerous benefits for both athletes and non-athletes. But did you know you should take this vitamin with an "r" standard throughout the winter months? This way, your vitamin D levels stay healthy, without them dropping throughout the winter.
Because we primarily produce vitamin D through sunlight—and let's be honest, that's rather scarce in Belgium, especially in winter—supplementing it isn't a luxury. That's why we're happy to explain why this is so important for you as an athlete.
Why athletes benefit extra from Vitamin D
Strong bones = stronger performance
Vitamin D plays a crucial role in bone health. For athletes who want to prevent injuries, recover faster, or have already suffered a fracture, vitamin D is a must-have.
Fewer muscle cramps
A vitamin D deficiency can contribute to muscle cramps during or after exercise. By supplementing properly, you significantly reduce this risk.
More energy & better resistance
A vitamin D deficiency can lead to fatigue and weakened immunity. One capsule a day can give your body a boost through the winter.
