Minerals take part in hundreds of enzyme reactions and are needed for nerve, muscle and immune function, and genuine deficiencies — such as iron deficiency — can cause symptoms. But each symptom below is common and has many possible causes, from thyroid disease and anemia to sleep disorders, mood disorders, medications and stress. None of them on its own means you have a mineral imbalance, and a hair test cannot tell you what is causing them. If a symptom is persistent, new or getting worse, see a licensed healthcare professional. Here are ten symptoms that are often linked to minerals:
1. Chronic Fatigue That Sleep Doesn't Fix
Ongoing fatigue despite enough sleep has many possible causes, including anemia, thyroid disease, sleep apnea, depression, infections and medications. Iron deficiency is a well-established cause of fatigue, and magnesium and potassium are involved in energy metabolism and muscle function. Persistent fatigue warrants medical assessment, which typically includes blood tests; a hair test cannot tell you why you are tired.
2. Brain Fog and Poor Concentration
Zinc, magnesium and iron are involved in brain and nerve function, and iron deficiency has been linked to poorer attention and concentration. But brain fog is also common with poor sleep, stress, depression, anxiety, thyroid problems, hormonal changes, infections and some medications. Ongoing trouble concentrating is worth discussing with a licensed healthcare professional.
3. Anxiety and Mood Swings
Calcium and magnesium help regulate nerve impulses, and some studies have explored links between magnesium, zinc, copper and mood. Those links are not established as causes of anxiety or mood swings, which have many causes — including anxiety and mood disorders, thyroid problems, hormonal changes, stress, and substances such as caffeine or alcohol. Mood symptoms deserve assessment by a licensed healthcare professional; HTMA cannot identify their cause.
4. Hair Loss or Thinning
Iron and zinc deficiency can contribute to hair shedding, and too much selenium can cause hair loss. But hair loss also commonly results from genetics (pattern hair loss), thyroid disease, hormonal changes, childbirth, illness, stress, medications and scalp conditions. A doctor or dermatologist can assess the cause, usually with an examination and blood tests. HTMA measures elements in the hair you submit; it does not show what your body "prioritizes", and it cannot diagnose the cause of hair loss.
5. Muscle Cramps and Spasms
Calcium, magnesium, potassium and sodium all help regulate muscle contraction, and markedly abnormal blood levels can cause cramps or spasms. But most muscle cramps and eyelid twitches are linked to other factors — exercise, dehydration, prolonged sitting or standing, fatigue, caffeine, some medications, pregnancy, and nerve or circulation problems. Frequent or severe cramps warrant medical assessment; electrolyte problems are checked with blood tests, not hair.
6. Difficulty Losing Weight
Iodine and selenium are needed to make and activate thyroid hormone, and chromium is involved in how the body uses insulin. But difficulty losing weight is most often linked to other factors — diet, activity, sleep, stress, age, medications, and medical conditions such as hypothyroidism or polycystic ovary syndrome. Thyroid function is assessed with blood tests such as TSH. Hair ratios such as Ca/K (calcium to potassium) are not tests of thyroid function, and "metabolic typing" is a concept used by some practitioners, not an established way to explain weight.
7. Weak or Brittle Nails
Spoon-shaped nails (koilonychia) can be a sign of iron deficiency, and nail changes can occur with other deficiencies. But weak, brittle or peeling nails are far more often due to frequent hand-washing, water and chemical exposure, nail polish and removers, injury, ageing, fungal infection, or skin and thyroid conditions. Small white spots are usually caused by minor injury to the nail, and vertical ridges are common with age. Persistent nail changes are worth showing to a doctor.
8. Frequent Illness or Slow Healing
Zinc deficiency is known to impair immune function and wound healing, and selenium and copper also play roles in immunity. But frequent infections or slow healing have many possible causes — including diabetes, poor circulation, some medications, immune disorders, smoking, poor sleep and stress — and warrant medical assessment rather than self-treatment.
9. Insomnia or Restless Sleep
Magnesium is involved in nerve and muscle function, and some studies have looked at magnesium and sleep quality, with mixed results. Insomnia, however, is most often linked to stress, anxiety, depression, sleep habits, pain, caffeine, alcohol, medications, menopause, and sleep disorders such as sleep apnea. Hair ratios such as Na/K (sodium to potassium) do not measure stress responses or sleep. Ongoing sleep problems are worth discussing with a licensed healthcare professional.
10. Sugar and Salt Cravings
Cravings are often linked to mineral needs online, but evidence that sugar cravings indicate chromium, magnesium or zinc deficiency is limited. Cravings are strongly influenced by habit, sleep, stress, mood, meal timing and the menstrual cycle. Strong, persistent salt craving can occasionally be a symptom of a medical condition such as adrenal insufficiency (Addison's disease) and should be discussed with a doctor — a hair test cannot diagnose it.
Experiencing These Symptoms?
See a licensed healthcare professional — these symptoms have many possible causes, and some need prompt medical assessment. HTMA cannot tell you the cause of a symptom. If you want an educational look at your hair mineral pattern, HTMA measures a laboratory panel of nutrient minerals and toxic metals in the hair sample you submit, reported against the laboratory's reference intervals.

If several of these symptoms sound familiar, start with a licensed healthcare professional, who can check for common medical causes — many of which, such as anemia or thyroid disease, are diagnosed with blood tests. Don't start, stop or change supplements or medications on your own: some minerals cause harm in excess (for example, too much zinc over time can lead to copper deficiency). A hair test does not replace that assessment. If you choose HTMA for educational context, the Comprehensive HTMA test pairs the laboratory report with our educational Report of Findings, written by our FDN-P practitioner. It is not a diagnosis or treatment plan, and any suggestions are for you to discuss with your healthcare provider.
