Essential and Toxic Elements: What Your Body Might Be Telling You Our bodies rely on a careful balance of essential elements to function optimally, but we're also exposed to potentially toxic elements through everyday environmental and dietary sources. Identifying the right levels of these elements can have a profound impact on health. Let’s explore what each element reveals and how advanced testing methods like dried urine and dried blood spot (DBS) testing provide critical insights. Essential Elements Iodine Iodine is critical for thyroid hormone production (T4 and T3). Found in dairy, seafood, iodized salt, and grains, this nutrient must be...

The Hidden Impact of Essential and Toxic Elements on Our Health Have you ever wondered how the environment around you affects your health on a molecular level?

Iodine deficiency is more common than many realise. This guide walks through how to assess iodine status using dietary recall, symptom profiling, and a three-part laboratory panel — including thyroid function, thyroglobulin, and urinary iodine and bromine testing.

A growing body of research suggests that mitochondrial dysfunction may lie at the root of many treatment-resistant mental health conditions — including depression, anxiety, bipolar disorder, OCD and even dementia. In this clinical overview, Dr. Peter Bongiorno explains why neurons are particularly vulnerable to mitochondrial damage, how stress, heavy metals and hormonal imbalances compound the problem, and what a comprehensive 5-step repair plan looks like in practice.
