Calm focus and relaxation; Stress support
Adults with high-stress, busy days seeking calm focus and those who want steady, extended-release theanine support without multiple doses.
Take 1 tablet once daily, preferably at a consistent time; may be taken with or without food. If sensitive, consider taking in the evening or with a snack to gauge comfort.
Gluten Free; Non-GMO LE Certified
L-theanine may increase calming neurotransmitters like GABA and support alpha brain wave activity for relaxed focus without drowsiness.
Caution: May cause drowsiness in some people; try first dose when you can gauge your response. Use caution with sedative herbs or supplements because effects may add up.
Calcium serves as a cellular signaling mineral involved in nerve transmission and muscle function.
Caution: Total daily calcium intake from diet and supplements adds up; avoid excessive intake if you already use high-calcium products.
Phosphorus partners with calcium in bone structure and supports energy metabolism as part of ATP.
Caution: High phosphorus from diet and supplements can affect mineral balance; keep overall intake moderate.
L-theanine promotes calm alertness by modulating neurotransmitters and brain wave activity, while the extended-release delivery aims to maintain steady levels over several hours. The small amounts of calcium and phosphorus contribute general mineral support but are not primary drivers of the formula’s calming effect.
Label Warning: Do not exceed the recommended dose. Consult a physician if you are being treated for a medical condition or if you are pregnant or nursing.
Who should be cautious: People who are pregnant, nursing, or being treated for a medical condition should consult a healthcare provider before use.
Storage: Store tightly closed in a cool, dry place.
