The sunshine vitamin is the best-selling supplement worldwide – 80% of people in northern latitudes are deficient in winter.
Vitamin D is by far the most commonly supplemented vitamin worldwide. From October to March, the body produces virtually no Vitamin D of its own in northern latitudes. This affects office workers, seniors, athletes and anyone who doesn't regularly spend time in the sun. Demand is massive and consistent.
Anyone sitting indoors all day gets almost no UV-B radiation in winter. A daily dose of Vitamin D3 (ideally combined with K2) compensates for this deficit and supports the immune system and bone metabolism.
Intense training challenges the immune system. Studies show that athletes with adequate Vitamin D get sick less often and recover faster. Runners and cyclists benefit most.
With age, the skin's ability to produce Vitamin D declines. For bone health and fall prevention, supplementation is frequently recommended by physicians.
Pediatricians recommend Vitamin D for infants and toddlers in their first year of life. Older children benefit too – a growing market with high trust from the target audience.
The domain vitamin.plus combines the authority of a premium keyword with the modern .plus extension – ideal for D2C brands, comparison portals or health platforms looking to capture market share in the Vitamin D space.
