20 Jul 2016 --- Although some people worry that they aren't getting enough vitamin D, which is critical for bone health, new research shows that they may be consuming more than they think. Vitamin D is naturally present in foods such as salmon, trout, sardines, liver, egg yolks and cod liver oil, and it's also in fortified milk, cereal and orange juice, as well as dietary supplements. Plus, sunlight triggers the production of vitamin D and contributes to people's levels.
