Solgar L-Theanine 150 mg delivers a precise, research-backed dose of Suntheanine® — a patented, pharmaceutical-grade form of L-Theanine produced through a proprietary enzymatic process that mirrors the natural biosynthesis found in green tea leaves. Each vegetable capsule provides 150 mg of free-form L-Theanine, allowing for flexible single or double servings to meet individual needs.

Suntheanine® is one of the most studied and recognised forms of L-Theanine available, consistently used in clinical research. Solgar’s free-form delivery ensures the amino acid is readily available for absorption without the need for digestion of a protein chain, making it a smart choice for those seeking a high-quality, well-characterised ingredient.

Formulated without unnecessary additives, this product is free from gluten, dairy, soy, artificial flavours, colours and sweeteners. The vegetable capsule shell makes it fully suitable for vegans and vegetarians, reflecting Solgar’s longstanding commitment to clean, inclusive formulation standards.
