Over 90% of serotonin, a neurotransmitter that regulates mood, sleep, and appetite, is produced from the amino acid tryptophan. These building blocks of protein are far more than just structural components; they are essential for the brain's complex functions, including communication between nerve cells, energy production, and detoxification.

The human brain, despite making up only about 2% of total body weight, consumes roughly 20% of the body's total energy expenditure at rest. For normal function, the brain's main fuel is glucose, a constant and reliable energy source delivered via the bloodstream. However, in extreme starvation, the body initiates a profound metabolic shift, forcing the brain to eventually utilize an alternative energy source.

A 2020 systematic review on oral GABA found only low to moderate evidence for stress reduction and low evidence for sleep benefits, highlighting the complexity behind the question: can you absorb GABA? The body's processing of supplemental GABA is a subject of ongoing research, with much debate over how it exerts its effects.

Over 90% of the body's free radicals are produced in the mitochondria. MitoQ was specifically designed to target this cellular powerhouse, and extensive research confirms: does MitoQ cross the blood-brain barrier to deliver neuroprotective benefits? The evidence overwhelmingly shows it can, thanks to its unique molecular structure and positive charge.

Multiple studies have now demonstrated that anthocyanins and their derived metabolites can successfully cross the blood-brain barrier. This critical ability allows these plant compounds to exert direct antioxidant and anti-inflammatory effects within the central nervous system, influencing brain health and potentially mitigating neurodegenerative diseases.

The human brain, despite making up only 2% of the body's weight, consumes an astounding 20% of the body's total energy, primarily relying on glucose for its fuel. This surprising fact raises a fundamental question: why doesn't the brain use fatty acids for its direct energy needs, especially given their high energy density?

The human brain, despite making up only 2% of the body's mass, consumes nearly 20% of the body's total energy, confirming its voracious metabolic appetite. To sustain this intensive activity, the brain requires an almost continuous supply of two primary resources: oxygen and glucose. Without these, neurons rapidly cease to function, with irreversible damage beginning in a matter of minutes.

Over one-third of the world's population is affected by iron deficiency, which can have profound effects on the body's ability to transport oxygen. The critical mineral that carries oxygen to the brain, and indeed to all other tissues, is iron, an essential component of hemoglobin.

The human brain, though accounting for only 2% of body weight, consumes approximately 20% of the body's total energy, primarily in the form of glucose. This fact highlights the critical role of glucose as the major source of fuel for neurons, as well as for red blood cells (RBCs), which have their own unique metabolic constraints.

The brain requires a highly controlled and constant supply of iron for proper function, with its needs met through a complex transport system that primarily relies on the blood-brain barrier. This critical mineral is essential for everything from neurotransmitter synthesis to myelin production.
