1. Need a mint?

If you still have bad breath even after brushing and flossing your teeth, your oral hygiene probably fine, and a vitamin B3 deficiency is the likely cause.

Since vitamin B3 is responsible for liver function, not having enough can result in your stomach and intestines to work improperly, and poor digestion, which is a major cause of bad breath.

This deficiency is also commonly found in people struggling with long term alcoholism. To get more of this vitamin in your diet you can eat fatty fish, organic meats, sunflower seeds, and beets.

2. Feeling more down than usual?

It's normal to feel a little blue sometimes, but if you notice your sadness lingering around, and you begin to feel depressed on a daily basis, you could be experiencing a deficiency in vitamin B1.

In order for your brain and nerve cells to function properly your body needs adequate vitamin B1 levels.

Alcoholism, anorexia, and Crohn's disease are likely causes of low vitamin B1 levels, and are likely to result in psychological problems when left untreated. Adding foods like peas, lentils, blackstrap molasses, and organ meats are great ways to get the B1 you need.
