5 Signs Your Body May Be Nutrient Deficient

1. Cracks at the Corners of Your Mouth

This can be a sign of iron, zinc, and B-vitamin (niacin, riboflavin, and B12) deficiency, or that you’re not getting enough protein. Good dietary sources of these nutrients include organic free-range poultry and eggs, wild-caught Alaskan salmon, oysters, and clams (if you can be sure they are harvested from non-polluted waters), Swiss chard, and tahini.

Because iron absorption is enhanced by vitamin C, be sure your diet also includes plenty of vitamin C-rich veggies like broccoli, red bell peppers, kale, and cauliflower.

Magnesium deserves special mention because an estimated 80 percent of Americans are deficient in it. 
Early signs of magnesium deficiency include loss of appetite, headache, nausea, fatigue, and weakness. An ongoing magnesium deficiency can lead to more serious symptoms, including:

Numbness and tingling	Muscle contractions and cramps	Seizures
Personality changes	Abnormal heart rhythms	Coronary spasms

 it would be highly unusual for most people to have access to foods that are rich in magnesium, which is why I believe it is prudent to consider a magnesium supplement.

another way to improve your magnesium status is to take regular Epsom salt baths or foot baths. Epsom salt is a magnesium sulfate that can be absorbed into your body through your skin.
