Feeling tired all the time, dull skin, brittle nails, or persistent brain fog? This may be your body’s way of signaling nutritional deficiency. Dr. Saurabh Sethi, a gastroenterologist trained at Ames, Harvard, and Stanford universities, in his October 20 Instagram post outlines 8 subtle signs that indicate your body may be lacking in essential vitamins and minerals and how to correct them before they affect your overall health.

1. You are tired all the time, even after sleeping
Low levels of iron, vitamin B12, or magnesium may be responsible. He explains, “These nutrients boost your metabolism and oxygen delivery. Without them, fatigue becomes persistent.”
2. Brittle nails or hair loss
It is often associated with zinc, biotin, protein, or iron deficiencies. “When nutrients become depleted, your body prioritizes vital organs rather than hair and nails,” says Dr. Sethi.
3. Always being cool, even when others aren’t
If you constantly feel cold, it may point to low iodine or iron levels, which are important for thyroid function and red blood cell production. He adds, “Chronic cold hands or feet are red flags you shouldn’t ignore.”
4. Muscle cramps or twitching
“Low levels of magnesium, potassium or calcium are common causes, especially if your gut is not absorbing nutrients properly,” says Dr. Sethi. “Think beyond hydration when cramping frequently.”
5. Brain fog or trouble concentrating
You may be deficient in omega-3 fatty acids, vitamin D, B12, or choline. “These nutrients are important for neurotransmitter function and overall brain performance,” he explains.
6. Gums that hurt or bleed easily
According to Dr. Sethi, “These are classic signs of a vitamin C or K deficiency. Vitamin C strengthens blood vessels, while vitamin K supports proper clotting.”
7. Cracks in the corners of your mouth (angular cheilitis)
“This often indicates low vitamin B, especially B2 and B6, or iron deficiency,” says Dr. Sethi. “If it keeps coming back, get tested.”
8. Loss of appetite or strange cravings
“Craving snow or dirt may point to an iron or zinc deficiency, while low appetite may be linked to poor gut signaling or a B12 deficiency,” he said.
Dr. Sethi concludes, “Don’t wait for a blood test to tell you that something is wrong. Your body gives signals early, listen to them and nourish yourself well.”
