What the Evidence Says

✨ AI-generated · Qwen 3.6 · grounded in 1 source · methodology

L-tyrosine is an amino acid used to support cognitive function and alertness during stress, while vitamin B6 aids in neurotransmitter synthesis. Research providing evidence for these cognitive benefits is generally limited to specific high-stress scenarios. Both ingredients are widely regarded as safe for general consumption.
