Vitamin D is a rarity in the world of nutrition. We don't just get it from food; our bodies can also produce it when our skin is exposed to sunlight. It is therefore the quintessential sunshine vitamin. And its role in bone health is as crucial as it is silent: without sufficient vitamin D, calcium is not properly absorbed, bones become more fragile, and muscles can ache for no apparent reason.
The body's ability to synthesize vitamin D decreases with age. Furthermore, many people spend more time indoors, constantly use sunscreen, or live for extended periods in dimly lit areas. The result is a widespread deficiency, affecting millions of people worldwide, according to the World Health Organization, particularly those over 50.
