Has this been used on horses?

29 horses in the study received Glutathione Swish30.

29 horses in the study did not receive Glutathione Swish30.

Blood tests were performed by equine veterinarians after the competition to measure oxidative stress and the results of the blood work were back that afternoon.

• 100% of the horses who received Glutathione Swish30 in the study; reduced their oxidative stress (inflammation) by 16-20%. 
• 100% of the horses who received Swish30 in the study: reduced their heart rate after a race or competition in 5 to 7 minutes. Normally this reduction in heart rate takes about 30 minutes.
• 100% of the horses that received Glutathione Swish30 did not need their legs wrapped.
• 100% of the horses in the study that received Glutathione Swish30 had less sweating and cool down time.

None of the horses in the study that did not receive Glutathione Swish30 lowered their heart rate earlier than expected or reduced their oxidative stress after racing and competitions. 

This is unheard of. Equine Supplements do not do these things!
