Your body makes vitamin D when you're exposed to sunshine. It's also present in salmon, tuna, and fortified foods. If you're low on vitamin D, your doctor may suggest a supplement; but several large studies show no benefits to otherwise healthy adults.
Also called "good" bacteria, probiotics are found in fermented foods like yoghurt, kombucha, miso, and sauerkraut. They can change the balance of good and bad bacteria in your body and may help improve digestion, soothe skin irritation, lower cholesterol and support your immune system.

Here's a vitamin you definitely want to make sure you have enough of if you're a woman who's planning to get pregnant. Getting enough folic acid can help prevent birth defects in a baby's brain and spine. You need 400 micrograms per day, in this case it is highly recommended to take that much in a supplement form, along with whatever you get from your diet.

Fish like salmon and sardines contain healthy fats called omega-3 that can lower your risk of heart disease. If you don't eat fish, there are fish oil supplements with omega-3s, like EPA and DHA, and there are algae-based supplements. But, again, more research is needed, because omega-3s formula in pills may work differently than the natural one contained in fish.
This hormone plays an important role in sleep. Your body produces it, and it's commonly sold in pill form.

This mineral supports your body in lots of ways. It gives you energy and keeps your heart healthy, for example.

This is an antioxidant your body makes, and you can get more of it in pill form. People try to use CoQ10 to fight migraines, protect the heart, and improve symptoms of Parkinson's disease.

CoQ10 can interact with blood thinners and insulin treatments, so check with your doctor before taking it.
