Could Heavy Metals or Mineral Imbalances Be Disrupting Your Hormones and Health?

Toxic elements like mercury and cadmium accumulate silently in the body over years, while deficiencies in essential minerals like selenium, zinc, and magnesium can directly disrupt female hormones, thyroid function, fertility, and energy. Women are particularly vulnerable — hormonal fluctuations across the menstrual cycle, pregnancy, perimenopause, and menopause can increase susceptibility to both toxicity and deficiency. If you recognise any of the following, this test could uncover a hidden root cause:

Persistent fatigue or exhaustion that sleep does not fix
Brain fog, slow thinking, or poor memory
Muscle aches, cramps, or weakness
Anxiety, irritability, mood swings, or depression
Difficulty sleeping or restlessness
Tingling, numbness, or twitching in hands and fingers
Irregular heartbeat or palpitations
Brittle hair and nails, dry or scaly skin
Irregular, heavy, or painful periods
Fertility concerns or difficulty conceiving
Low libido or loss of interest in sex
Symptoms worsening around perimenopause or menopause
Concerns about heavy metal exposure from diet, fish, environment, or dental fillings

What This Test Measures

Dried Blood Spot — Toxic & Essential Elements (ICP-MS):

Cadmium (Cd) — toxic metal accumulating in the kidneys; mimics oestrogen and is linked to breast cancer risk, fertility problems, and menstrual disruption; sources include cigarette smoke and contaminated food
Mercury (Hg) — organic mercury from fish and dental amalgam binds to red blood cells; linked to thyroid damage, neurological decline, and hormonal disruption; whole blood is the most accurate indicator of exposure
Selenium (Se) — critical for thyroid hormone conversion, antioxidant defence, and immune function; deficiency is common in the UK and particularly impacts women with thyroid or autoimmune conditions
Zinc (Zn) — essential for hormone production, immune function, and fertility; low zinc is associated with PMS, cycle irregularities, and poor egg quality
Magnesium (Mg) — involved in 300+ enzymatic reactions including oestrogen metabolism and progesterone production; deficiency is strongly linked to PMS, period pain, anxiety, and insomnia in women
Copper (Cu) — essential in balance with zinc; excess copper — common in women taking the contraceptive pill or using a copper coil — is linked to anxiety, oestrogen dominance, and thyroid dysfunction; the zinc-to-copper ratio is a key health marker

Why These Elements Matter Specifically for Women

In women, toxic heavy metals and mineral imbalances interact directly with female hormones, amplifying their effects across every life stage:

Hormonal disruption and oestrogen dominance
Infertility, miscarriage risk, and menstrual irregularities
Thyroid dysfunction (mercury and cadmium interfere with thyroid hormone production)
Worsening perimenopause and menopause symptoms
Neurological decline and cognitive impairment
Cardiovascular disease and metabolic dysfunction
Liver and kidney damage from accumulated toxins
Immune suppression and increased cancer risk

Who Is This Test For?

This test is ideal for women who want to:

Investigate unexplained fatigue, mood changes, or hormonal symptoms
Assess how diet, environment, or hormonal contraception may be affecting their element status
Check selenium and zinc as part of a thyroid or hormone health investigation
Explore possible root causes of PMS, cycle irregularities, or fertility concerns
Monitor mineral status during supplementation or HRT
Take a proactive approach to long-term hormonal and cardiovascular health

Frequently Asked Questions

Can heavy metals disrupt female hormones?
Yes. Cadmium is a known oestrogen mimetic — it binds to oestrogen receptors and can drive oestrogen dominance, associated with PMS, endometriosis, fibroids, and breast cancer risk. Mercury disrupts thyroid hormone production and has been linked to irregular cycles, fertility problems, and worsening perimenopause symptoms.

Why is copper elevated in women on the pill?
Oestrogen — including synthetic oestrogen in hormonal contraceptives — increases copper retention. Women taking the combined pill or using a copper IUD often have elevated copper and a depleted zinc-to-copper ratio, associated with anxiety, low mood, oestrogen dominance, and thyroid dysfunction.

How does magnesium deficiency affect women specifically?
Magnesium is essential for progesterone production, oestrogen metabolism, and HPA stress axis regulation. Deficiency is strongly associated with PMS, severe period pain, premenstrual anxiety, poor sleep, and worsening perimenopausal symptoms.

Does mercury affect fertility?
Yes. Mercury accumulates in the ovaries and disrupts follicular development and hormone signalling. Elevated mercury is associated with reduced ovarian reserve, irregular cycles, and increased time to conception. Women who eat fish regularly or have dental amalgam fillings are at greater risk.

Is this test suitable when trying to conceive?
Yes — this test is suitable for women trying to conceive who want to understand their toxic element burden and mineral status. If you are already pregnant, please consult your midwife or GP before ordering.

Does the price include the laboratory fee?
Yes. The full laboratory analysis fee is included. There are no additional charges. You are responsible for posting your sample to the laboratory. The kit is valid for 12 months from purchase.
