Probiotics are "good" bacteria that live in your intestine and help your body fight off infections and diseases. They also may help with digesting food. Two of these bacteria are called Lactobacillus acidophilus and Bifidobacterium bifidum. If you don't have enough probiotics in your gut, you may have gas, stomach problems, diarrhea, yeast infections, or other more serious infections in your intestine.
Vitamin B2 (Riboflavin)
Symptoms of vitamin B2 deficiency may include cracks at the corners of the mouth, scaly skin, a red and inflamed tongue, swollen mouth or throat, and bloodshot eyes that are sensitive to light.
Vitamin B9 (Folic Acid)
Low levels of folic acid have been linked to anemia, heart disease, birth defects, and colon cancer. Symptoms may include fatigue, mouth sores, swollen tongue, and poor growth.
Vitamin B12 (Cobalamin)
Noticeable symptoms of a vitamin B12 deficiency can take years to show up. Irritability, weakness, numbness, anemia, loss of appetite, headache, personality changes, and confusion are some of the signs and symptoms associated with very low levels of vitamin B12. Low levels of this vitamin may also be associated with an increased risk of colon cancer, heart disease, brain problems, and birth defects.
Vitamin H (Biotin)
Low levels of biotin are linked with dry skin, hair that breaks easily, hair loss, depression or altered mental status, nausea and vomiting, loss of appetite, and muscle pain.
The major symptom of vitamin K deficiency is that your blood doesn't clot as it should. You might notice that you bruise easily or have nosebleeds or bleeding gums. Women may have heavy periods. Internal bleeding, which can be life-threatening, may also be caused by lack of vitamin K.
