Swanson N-Acetyl L-Tyrosine 35mg, 60 Capsules - Amino Acid Food Supplement for Cognitive Function

How Does It Work?

Once ingested, N-Acetyl L-Tyrosine (NALT) is deacetylated to L-tyrosine, which then crosses the blood-brain barrier. In the brain, it serves as a building block for catecholamines—chemical messengers that regulate mood, motivation, and attention. By ensuring adequate tyrosine levels, NALT may help maintain optimal neurotransmitter function, especially under conditions of high demand or stress. This mechanism supports the body's natural ability to adapt to stressors and sustain mental performance over time.

What Is N-Acetyl L-Tyrosine?

N-Acetyl L-Tyrosine (NALT) is a highly bio-available form of the amino acid L-tyrosine. As a precursor to dopamine, norepinephrine, and epinephrine, it supports neurotransmitter production. This food supplement is designed to help maintain mental clarity and focus, especially during stress or demanding tasks. Unlike standard L-tyrosine, NALT is acetylated to improve solubility, whilst absorption efficiency can vary amongst individuals. Swanson's N-Acetyl L-Tyrosine is formulated to support overall cognitive function and centre nervous system health, making it a versatile addition to your wellness routine.

Recommended Dosage and Usage

For most adults, a typical dosage ranges from 35 mg to 1,000 mg per day. Each capsule of Swanson N-Acetyl L-Tyrosine provides 35 mg. The suggested uses is one capsule daily with water, preferably 20-30 minutes before a meal for optimal absorption. As with any supplement, it is advisable to start with the recommended dose and adjust as needed under the guidance of a health care professional. Do not exceed recommended intake without consulting a doctor. For maximum benefit, consistency is key—take it at the same time each day to maintain steady levels.

Key Benefits for Brain and Body

Supplementing with N-Acetyl L-Tyrosine supports cognitive function and physical performance. It is widely used to promote mental energy, concentration, and a balanced mood. During periods of stress, tyrosine levels can become depleted; NALT helps replenish them, aiding cognitive flexibility and resilience. Additionally, it may support the body's response to physical stressors, making it a popular choice amongst athletes and busy professionals. Many users report improved focus and reduced mental fatigue when taking N-Acetyl L-Tyrosine regularly. It also contributes to normal neurotransmitter synthesis, helping maintain a healthy stress response. As with any supplement, individual results may vary.

Potential Side Effects

N-Acetyl L-Tyrosine is generally well tolerated. Some individuals may experience mild gastrointestinal discomfort or headache when first starting. If you have a history of thyroid conditions, bipolar disorder, or are taking MAO inhibitors, consult your doctor before uses. As with all supplements, discontinue uses if adverse reactions occur. Keep out of reach of children, and store in a cool, dry place.
