Monitor for neurological and digestive effects when combining Casein Protein with L-Histidine. Amino acids can influence neurotransmitter production and interact with bioactive compounds in botanicals and supplements. Watch for: changes in mood, energy, or sleep patterns; digestive upset (nausea, bloating); headache; restlessness; or vivid dreams. Start at lower doses and increase gradually.
