Calming formula is recommended for pets exposed to increased environmental stressors. When pets can't adapt to stress it can lead to nervousness, hyperactivity, excess barking, abnormal urine marking, excessive scratching, and destructive or aggressive behavior. Calming helps alleviate stress related behavior problems without affecting your pet's personality or energy level. It can be used daily or when extra help to relax is needed. It contains a combination of factors not found in other calming formulas such as a Colostrum Calming Complex, L Theanine, and Thiamine (Vitamin B1) which all address stress and calming. Colostrum Calming Complex is isolated from colostrum proteins which have a calming effect on animals. These bioactive proteins have been found to support cognitive functioning and support stress reduction. The Colostrum Calming Complex works synergistically with the L Theanine in this formula to promote relaxation and cognition. L Theanine supports calming and relaxation reduces irritability and low mood states. L Theanine has been extensively researched for its ability to help curb destructive behavior. L Theanine is a naturally occurring amino acid found in green tea. It helps the body to produce other calming amino acids, such as Dopamine, GABA and Tryptophan, and helps bring certain neurotransmitters into better balance. Studies down on L Theanine showed dogs were calm and relaxed without adverse effects or drowsiness; dogs were alert, playful, and calmer than expected, given their situations. B Vitamins help manage stress and help maintain normal disposition. Thaimine (Vitamin B1) has been shown to affect the central nervous system to help calm and relax animals. Calming does not contain any herbal ingredients (Kava Kava, Valerian, St. John's Work, etc.) or L tryptophan. Calming's ingredients do not cause side effects, addiction, and drowsiness or impaired motor skills.
