Premium supplement company Thorne has launched Clear Focus, a targeted nootropic formulated with sage extract and L-tyrosine to support attention, information processing and cognitive performance.
The caffeine-free formula contains 333 mg of SageXtra — a patented extract of sage leaves, standardised to contain 2.5% rosmarinic acid (an antioxidant polyphenol) — and 500 mg L-tyrosine, an amino acid precursor to the neurotransmitters dopamine, norepinephrine and epinephrine.
