Browse Memory & Mood Support Supplements

There are over sixty neurotransmitters that regulate mood, sleep, focus, fear, stress response, and other emotional states in humans. Their chemistry is complex, and how to manage these emotional states with medication is still not fully understood. Many anxiety and mood enhancing supplements can have challenging side effects, especially for young children. At Neurobiologix we are dedicated to providing high quality products that incorporate naturally occurring compounds and formulas to gently support pathways that impact serotonin, dopamine, cortisol, and excitatory/inhibitory neurotransmitters.

Our targeted supplements feature a unique combination of nutrients and botanicals proven to improve cognitive and memory function. If you’re looking for focus supplements, our new and improved Advanced Neurotransmitter Support formula may boost attention and concentration levels, but may also improve mood and sleeping patterns. And don’t forget, we also carry a variety of supplements for nervousness, hyper-activity such as our highly acclaimed Mood Plus product, Calming Cream and Neuro-Immune Stabilizer Cream.

Pregnenolone is the key precursor pro-hormone involved in maintaining sufficient steroid hormone levels in the body. It is the precursor (building block) for other hormones in the body including cortisol, DHEA, estrogen, progesterone, testosterone and aldosterone.


Without pregnenolone there can be no human steroid hormone production.

It has been shown to aid in:
*Energizing, Anti-stress Benefits
*Pro-Memory & Cognitive Effects
*Mood Elevation & Support Restful Sleep


Pregnenolone is known to modulate at least two key nerve receptors systems in the brain: NMDA receptors and GABA receptors. NMDA receptors are involved in learning, memory, and alertness. GABA receptors are involved in mood stability, relaxation, sex drive and sleep.


Niacinamide or otherwise known as Vitamin B3 works with vitamin B1, riboflavin (Vitamin B2), pyridoxine (vitamin B6), pantothenic acid, and biotin to break down and convert the carbohydrates, fats, and proteins in food into energy to help support the mitochondria. The involvement of niacin, an essential B vitamin, in cellular energy production makes it important for healthy cardiovascular function, nervous system function and immune function.
