The nutritional requirements to support the skeleton during growth and development and during ageing are unlikely to be notably different between athletes and the general population, although there are some considerations of specific relevance, including energy availability, low carbohydrate availability, protein intake, vitamin D intake and dermal calcium and sodium losses.

Energy availability is important for optimising bone health in the athlete, although normative energy balance targets are highly unrealistic for many athletes.

The level of energy availability beyond which there is no negative effect for the bone needs to be established. On the balance of the available evidence it would seem unlikely that higher animal protein intakes, in the amounts recommended to athletes, are harmful to bone health, particularly with adequate calcium intake.

Dermal calcium losses might be an important consideration for endurance athletes, particularly during long training sessions or events.

By maintaining calcium and phosphorus levels in the blood, vitamin D favours growth and bone health, as well as dental health. Therefore, vitamin. However, excessive vitamin D intake more than UI per day can damage the kidneys and other tissues.

Any attempt to increase intake above the Dietary Reference Intake for vitamin D must raise this question: is the intake provided through food and drinks sufficient?

A recent evaluation of vitamin D status showed that the serum level is generally sufficient to maintain good bone health. Nevertheless, athletes practising winter activities only indoors and who are not exposed to sunlight or outdoor light for at least 20 minutes per day may be at risk of deficiency.

Other foods also contain this element in non-negligible amounts, especially some green vegetables, and calcium-enriched food. Indeed, for the bones and the rest of the body to benefit from calcium, it must first be absorbed from food.

The conclusion of the meta-analysis was that vitamin K supplementation is associated with improved bone density and a decreased impact of fractures. They noticed that older people with a high vitamin K intake had a higher bone mineral density BMD than those with a lower dietary intake.
