We are heading into the new year with a goal to strengthen our understanding of hormones, neurotransmitters, and heavy metals and the influence they have on our overall health and wellness. As we welcome 2019, we would like to take a moment to look back at our most popular blog posts from last year. Serotonin, or rather its deficiency, frequently…

A Case Study for Menopause Awareness

Glycine has a calming effect on the brain – it helps you wind down and prepare for sleep. Its role as an inhibitory neurotransmitter has been unfolding over many years of ongoing research efforts. Easily one of the most versatile amino acids, glycine serves as a building block to proteins (collagen, the most abundant protein in our body, is one-third glycine), and is heavily utilized for the…

Glycine – A Small Molecule with a Big Impact on Sleep

Gamma-aminobutyric acid, better known as GABA, is the neurotransmitter known for its affinity for GABA receptors throughout the central nervous system (CNS). It acts to inhibit excitatory processes – whether they be normal or pathological. It's synthesized from the excitatory neurotransmitter glutamate in a process that requires vitamin B6 as a cofactor. The delicate balance in the brain between…

The Connection Between GABA & Sleep Disturbances

The hypothalamus is directly innervated by neuronal systems that produce neurotransmitters, such as serotonin (5-HT), dopamine and norepinephrine (NE), that are involved in mood regulation and play various other roles in cognitive health. During the acute stress crisis, the mesolimbic dopaminergic reward system is stimulated to help maintain morale. However, during chronic stress or depression, the reward system is down-regulated by stress mediators, resulting in anhedonia.…

Neurotransmitters, Mood & the Perception of Stress - Part 3

Influenced by our environment, we are constantly being exposed to elements, whether nutritional or toxic. They are a big contribution to the yin yang dualism of health and disease. With heavy metals, contamination is so extensive nowadays that it is no longer a question of whether exposure took place, but rather what the level of exposure was or continues to be. Toxicity from low levels of exposure…

Heavy Metals, Nutrients & Mental Health

Glutamate (L-glutamic acid) and GABA (gamma-aminobutyric acid) are, respectively, the principal excitatory and inhibitory neurotransmitters in the CNS and play a significant role in HPA axis function and mood. These two amino acid-based neurotransmitters account for over 50% of the synapses in the brain, while the monoamines (serotonin, norepinephrine and dopamine) account for only about 5%.…

Why are Mitochondria Important? Mitochondria are organelles that are present in every cell of the body except red blood cells. Probably everyone reading this learned about these little guys in high sch­ool biology, where they were described as "the energy packs of the cells."About 20% of our body weight is mitochondria. This translates to about 250 quadrillion of these organelles. There are 37.2…

Mitochondria & Mental Health

When we talk about “stress,” or allostatic load, in terms of the perception of an event, we must realize that these “events” must first be translated into neurochemical signals before they trigger the HPA axis. Therefore, the sensitivity and outcome of translating these events (whether they are ongoing events, memories of past events, or stressful anticipation of unrealized events), is highly dependent upon signaling from other neurotransmitters.…
