12 Signs You Are Vitamin D Deficient (And How To Get More)

About 57% of American adults and 36% of young adults in the USA and Europe suffer from lack of vitamin D. This vitamin is far more important than some people think as it plays a big role in many muscle and bone functions. Vitamin D has also been associated with lower risk of cancer, heart failure, high blood pressure and diabetes, which is why we should keep its levels under control.

Vitamin D deficiency is pretty hard to detect, and most people aren’t even aware of the problem. This is why it’s important to check your vitamin D levels several times a year in order to prevent further health problems.

The main source of vitamin D is the sun. How much you really need depends on your skin color, age, time of the day spent sunbathing and of course the amount of sunscreen you use. Sunscreen blocks the vitamin D absorption, so it’s best to avoid it if you keep your sun exposure to 10-15 minutes a day. If you plan on sunbathing for more, you must apply a high-quality sunscreen. There’s also another problem with sunscreen – many experts consider it carcinogenic. Luckily, there are a variety of natural options to protect yourself from sunburns such as coconut oil, so you can stay safe from the sun without harming your health.

Besides plenty of sunshine, there are also many dietary vitamin D sources. For those who live in areas with low sunlight, we suggest taking vitamin D supplements or eating more tuna, animal liver, cheese, egg yolks, etc.
