Allergy Research Group ARG L-Tyrosine 500 mg – Free Form Amino Acid Supplement – 100 Capsules

How L-Tyrosine Supports Your Brain and Body

When life demands more from your mind and body, L-Tyrosine can help you stay sharp and resilient. This conditionally essential amino acid serves as a building block for key neurotransmitters like dopamine, norepinephrine, and epinephrine—chemical messengers that influence mood, focus, and the body's stress response. Supplementing with free-form L-tyrosine provides a direct source that bypasses the conversion step from phenylalanine, making it readily available for neurotransmitter production.

Clinical research suggests L-Tyrosine may help maintain cognitive performance during stressful situations, sleep deprivation, or multitasking. By supporting neurotransmitter pathways, it plays a role in mood balance and motivation.* It also contributes to thyroid hormone production and supports healthy metabolism and nervous system function.*

What Is L-Tyrosine?

L-Tyrosine is a conditionally essential amino acid naturally found in protein-rich foods. While the body can synthesise it, certain conditions like stress, intense exercise, or cognitive demands can increase the need for dietary intake. Allergy Research Group ARG L-Tyrosine delivers 500 mg of pure, free-form L-tyrosine per capsule, designed for optimal absorption and utilisation.

Who May Benefit from L-Tyrosine?

L-Tyrosine supplementation can be valuable for students and professionals facing long study or work sessions, athletes seeking to maintain focus during training or competition, and individuals managing occasional stress or demanding lifestyles. Because L-Tyrosine is a precursor to dopamine, it is also popular among those seeking to support mood and motivation. Vegetarians and vegans may particularly benefit, as plant-based diets can sometimes result in lower tyrosine intake.

What Makes Allergy Research Group L-Tyrosine Stand Out?

Allergy Research Group has been a trusted name in dietary supplements for over 45 years. Their L-Tyrosine supplement is crafted with attention to purity and quality, with each batch tested for potency and contaminants. This formula is free form—meaning the amino acid is not bound to other compounds—enhancing its bioavailability. It is hypoallergenic, vegetarian, and free from gluten, dairy, soy, nuts, egg, shellfish, fish, and sesame, making it a safe choice for those with food sensitivities.

The brand is part of a family of science-backed companies including Metabolic Maintenance, MethylPro, Nutricology, and Optimox.

How to Incorporate L-Tyrosine into Your Routine

The recommended serving is one 500 mg capsule daily, or as directed by a healthcare professional. L-Tyrosine can be taken with or without food, though taking it on an empty stomach may improve absorption. For best results, consider using it during periods when mental clarity and focus are most needed, such as mornings or before demanding tasks.

As with any supplement, it is wise to consult with a healthcare provider before beginning use, especially if you are pregnant, nursing, or have a medical condition. L-Tyrosine should not be used as a substitute for a balanced diet and healthy lifestyle.
