🙏 Begin with prayer
Prayer is the first remedy, not the last resort. Here is a simple prayer you are welcome to make your own:
Lord Jesus, thank You for the calm You alone can give, and for the small gift of theanine that helps quiet a racing mind. Thank You that Your peace passes all understanding, far beyond what any supplement can offer. Give me wisdom in using this calmly and well, and grant me true peace that outlasts any capsule. If my anxiety grows heavy, lead me to seek help from a doctor or counselor too. In Jesus' name, Amen.
“And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.”— Philippians 4:7 (KJV)
