Welcome to my forum.
Here you will find more than 6 years of questions and my answers. It is searchable and offers a great deal of information.
Currently, I am discontinuing new questions. This may change in the future, but in the meantime, please know that It has been a true pleasure serving you.
Take a look at my Nutrition Library and Tips of the Month for a variety of answers on selected topics. Be sure to sign up for my monthly e-newsletter, Forage for Thought.
I also have a growing number of recordings on "Teleseminars on Nutrition Topics that Concern You" as well as the new, Spotlight on Equine Nutrition Series -- printed versions of favorite teleseminars.

Hi Lynn,
Yes, spirulina has been shown to be effective against many allergic responses. The recommended amount is 20 grams each day. Another consideration is to boost the immune system by adding antioxidants to the diet. This will help your horse combat the allergens that he is exposed to. PreOx is worth considering. I have had good results with this product.
All the best,
Dr. Getty
