Micronutrients That Support Endocrine Function and Weight Loss
Quick answer
Vitamins and minerals support normal body and hormone function, but taking extra micronutrients has not been shown to cause weight loss when there is no deficiency. Seek testing or advice before supplements, especially high-dose products, and address weight through evidence-based, individualised care.
Clinical perspective
Micronutrient deficiencies are remarkably common in individuals with obesity and can directly impair the endocrine pathways that regulate metabolism and weight.
Vitamin D deficiency is more common in people with obesity and is linked to insulin resistance, increased inflammation and impaired thyroid function. Selenium and zinc are essential cofactors for thyroid hormone conversion — without them, even a normally functioning thyroid gland cannot produce adequate active hormone.
Magnesium plays a critical role in over 300 enzymatic reactions including glucose metabolism and insulin signalling.
Chromium helps regulate blood sugar by enhancing insulin receptor activity, while B vitamins — particularly B12 and folate — are essential for energy metabolism and methylation pathways that influence weight.
At our clinic, we routinely screen for these deficiencies and address them as part of a comprehensive weight management plan.

Hypothyroidism and Weight: What Treatment Can and Cannot Fix
Treating hypothyroidism with appropriately prescribed levothyroxine corrects thyroid hormone deficiency but may not resolve weight changes unrelated to the thyroid. Take it as directed, separate it from iron or calcium as advised, and have thyroid tests reviewed before any dose change.
Why can illness make your thyroid results look abnormal?
Acute or serious illness can alter thyroid-hormone production, conversion, and test results without primary thyroid failure. Results need interpretation with symptoms, medicines, and history; testing or treatment decisions should be made with a clinician, often after recovery when appropriate.
What does DHEA do to fat and muscle?
DHEA is an adrenal hormone precursor that the body can convert into sex hormones influencing muscle and fat. Age-related declines do not establish a cause of weight or strength changes, and supplements have not reliably shown such benefits; use them only with medical advice.
