Here are quick body signals that may indicate deficiencies in key nutrients:

1 Eye twitching, also known as tetany, can be caused by a magnesium deficiency.

2 Dry, flaky skin is a classic sign of omega-3 fatty acid deficiency. High-quality fish oil can help.

3 Muscle weakness may be due to a vitamin E deficiency.

4 Cold sores may be viral, but increasing lysine (L-lysine) intake may help put the virus into remission.

5 Low libido can be caused by a zinc deficiency. Shellfish, especially oysters, and red meat are top sources.

6 Rapid heartbeat may result from potassium deficiency. You need 4700 mg of potassium daily.

7 Deep pelvic bone pain can be due to a vitamin D deficiency.

8 Tingling in the toes, also called peripheral neuropathy, may be caused by a vitamin B1 deficiency.
Pork, liver, meat, eggs, and sunflower seeds are excellent sources of B1.

9 Cracks at the corners of the mouth may be due to vitamin B2 deficiency.
Liver, red meat, and eggs can boost your B2 levels.

10 Thinning hair may indicate a biotin (B7) deficiency. Without biotin, your body can’t produce keratin, essential for hair growth.

11 Premature gray hair might be caused by a vitamin B9 deficiency. Folate (B9) supports DNA repair and melanin production.

12 Mouth ulcers can be linked to vitamin B12 deficiency. Eat more red meat, liver, and shellfish.

13 Hearing loss may also be related to vitamin B12 deficiency.

14 Chronic cough could be caused by a calcium deficiency. Calcium lactate is the best form of calcium supplement.

15 Craving ice may indicate an iron deficiency. Try increasing red meat or liver intake before using supplements.

16 Fibrocystic breast disease may be caused by estrogen dominance due to low iodine. Seaweed and shellfish are good iodine sources.

17 Fatty liver can result from a choline deficiency. Egg yolks and liver are top choline sources.

18 High lipid levels may be improved with niacin (vitamin B3).
