What is the recommended dosage for Taurine?

General: 500-2,000 mg/day; Cognitive Support: 1,000-3,000 mg/day

What are the side effects of Taurine?

Potential side effects include: Generally very well-tolerated, Mild gastrointestinal discomfort (rare), Drowsiness at high doses.

Taurine is a conditionally essential amino acid found abundantly in the brain, heart, and retina. It acts as an inhibitory neuromodulator and has antioxidant and anti-inflammatory properties. Research has explored its potential role in supporting GABAergic signaling and neuroprotection.

What dosage of Taurine has been used in studies?

Studies have used 500 mg to 3,000 mg of taurine daily. Cognitive and neurological research has commonly used 1,000 mg to 2,000 mg per day. Taurine levels decline with age, which has motivated supplementation research in older adults. Consult your healthcare provider.

What are the potential side effects of Taurine?

Taurine is generally well tolerated at recommended doses. Mild side effects may include nausea and digestive discomfort. Taurine may interact with lithium and antihypertensive medications. People with bipolar disorder or kidney disease should consult their healthcare provider before use.

About

Taurine is a conditionally essential amino acid abundant in the brain that modulates inhibitory GABA-A and glycine receptors. It supports neuronal calcium homeostasis and exhibits anti-excitotoxic and anti-inflammatory neuroprotective effects.

How It Works

Modulates inhibitory GABA-A and glycine receptors; supports neuronal calcium homeostasis; osmoregulatory role maintaining cell volume during neural activity; anti-excitotoxic and anti-inflammatory neuroprotective effects.
