Calcium Intake
Prioritize a balanced diet rich in calcium for bone health, especially during teenage years when about 1000mg daily is needed.
Dairy is the best calcium source; aim for three servings of milk, yogurt, or cheese daily.
volunteer_activism ADVICE
Vitamin D and Sun Exposure
Get sufficient vitamin D, crucial for calcium absorption. Sunlight is the most efficient source; expose skin safely during appropriate hours.
Consider supplements if adequate sunlight is impossible, but optimal levels and supplementation strategies are still debated.

Belinda Beck, founder of The Bone Clinic and a leading authority on exercise physiology and bone health, delves into the science of osteoporosis, bone density, and the lifelong importance of maintaining skeletal health. In this episode, she explains how the foundation for strong bones is established during childhood, offering valuable advice for parents on optimizing bone health for their kids. She also explores how bone remodeling occurs throughout life, driven by activity, nutrition, and hormones. Belinda highlights the power of resistance training in improving bone strength, even for those at risk of bone loss, and emphasizes the role of essential vitamins and minerals in maintaining bone health. She shares practical strategies, backed by research, for preventing fractures and combating osteoporosis.
