The Mineral Guide

Small minerals. Big influence on how you feel.

Your body can't make minerals. Every one has to come from what you eat and drink, and every system you're trying to heal, from your thyroid to your skin, depends on them. Here's how they work, what each one does, and why balance matters more than any single number.

How minerals work

Three jobs that run everything

1

They power your cells

Sodium and potassium act like a battery on every cell wall. That charge moves nutrients in, moves waste out, fires your nerves and keeps your heart beating. When the charge is weak, everything slows down.

2

They switch on your enzymes

Enzymes do the work of digestion, energy, detox and hormone-making, and most can't work without a mineral helper. Magnesium alone is involved in more than 300 of them, and zinc in hundreds more.

3

They work in balance

Minerals compete and cooperate. Too much calcium can push magnesium down; too much copper can push zinc down. That's why the ratios between them often say more than any single level.

Meet the key minerals

What each one does, and how to tell it may be low

MagnesiumMg

The calming mineral. Needed to make energy, relax muscles, steady your nervous system, keep your bowels moving and help insulin work. Stress, coffee, alcohol and sweating all burn through it.

May be low if you notice: muscle cramps or twitches, anxiety, headaches, constipation, chocolate cravings
Find it in: pumpkin seeds, leafy greens, avocado, almonds, dark chocolate
ZincZn

The repair mineral. Helps make stomach acid, heal skin and the gut lining, support immunity, convert thyroid hormone and keep hormones balanced. It's one of the most common deficiencies in women.

May be low if you notice: breakouts, slow healing, frequent colds, low appetite or dull taste, bloating after protein
Find it in: oysters, red meat, pumpkin seeds, eggs
CopperCu

The double-edged mineral. You need it to build collagen, use iron and make energy. But copper tends to rise with estrogen, and when it builds up relative to zinc, it can leave you wired, anxious and inflamed.

Out of balance if you notice: racing thoughts, PMS, headaches, skin flushing, or fatigue that iron alone doesn't fix
Find it in: liver, shellfish, cashews, dark chocolate
SodiumNa

The stress-response mineral. Keeps fluids and blood pressure steady, helps make stomach acid and works closely with your adrenal glands. Low-salt eating and long-term stress can leave you running low.

May be low if you notice: dizziness when you stand, salt cravings, fatigue, low stamina
Find it in: unrefined sea salt, bone broth, olives
PotassiumK

Sodium's partner. Needed for steady heartbeat, muscle strength and moving glucose into cells. HTMA practitioners also use it to see how well thyroid hormone is reaching your cells.

May be low if you notice: weakness, muscle cramps, heart flutters, fatigue, blood sugar swings
Find it in: avocado, potatoes, coconut water, leafy greens, beans
CalciumCa

The structure mineral. Builds bones and helps muscles contract and nerves signal. It needs magnesium, vitamin D and vitamin K2 to go where it belongs. HTMA practitioners watch for calcium building up in tissues, a pattern often linked to a slower metabolism.

Out of balance if you notice: feeling sluggish or flat, stiffness, constipation, a "stuck" metabolism
Find it in: dairy, sardines with bones, leafy greens
SeleniumSe

The thyroid protector. Needed to convert thyroid hormone into its active form and to make one of your body's main antioxidants. It also helps protect against mercury. A little goes a long way, so more isn't better.

May be low if you notice: thyroid symptoms, hair thinning, frequent illness
Find it in: Brazil nuts (1–2 a day is plenty), seafood, eggs
ChromiumCr

The blood sugar helper. Strengthens insulin's signal so your cells can take in glucose. Diets high in sugar and refined carbs use more of it and supply less.

May be low if you notice: sugar cravings, energy crashes, shakiness between meals
Find it in: broccoli, green beans, meat, eggs

These signs can have many causes, and none of them diagnose a deficiency on their own. That's exactly why testing matters.

The ratios that tell the real story

On an HTMA, these pairs often reveal more than any single mineral. Here's what practitioners look for.

Na : K
Sodium to potassium

Reflects your stress response and adrenal energy. It can point to whether you're pushing hard on stress hormones or running on empty.

Ca : K
Calcium to potassium

Often called the thyroid ratio. It suggests how well thyroid hormone is working at the level of your cells, even when bloodwork looks normal.

Ca : Mg
Calcium to magnesium

Relates to blood sugar balance and how calm or tense your nervous system feels. Magnesium keeps calcium in check.

Zn : Cu
Zinc to copper

Connected to estrogen balance, skin, mood and immunity. When copper runs high and zinc runs low, PMS, anxiety and breakouts are common.
