Spirulina is a blue-green algae that is an excellent source or vitamins, minerals, protein, phytonutrients, and amino acids. It is commonly used to relieve allergies and breathing problems. One of our horse listeners found it very helpful to eliminate a goopy eye problem. I used it with Zorra and it also helped greatly reduce her eye discharge. But for her eye discharge to completely clear up, my daughter had to start spending time with her regularly - remember, mind/body/spirit are ONE. So we need to treat the whole horse! And the message Zorra was sending us through her body, was that she really needed my daughter Zara to be with her (for both their sakes).

The only thing you should know about spirulina is that most horses don't like it's taste. So you have to start with a very small amount and gradually build up over time. Drizzling with flax or hempseed oil also helps with ingestion. I would sprinkle it in Zorra's feed dish (in this order: pure alfalfa pellets or chopped hay, High Point Daily Nutrients, spirulina, 1 tbsp seaweed powder, = flax oil).

Also check out our Respire product, which contains Spirulina, MSM, Jiaogulan and Vitamin C, Turmeric.

p.s. You may have heard that some species of blue-green algae naturally produce toxins called microcystins which accumulate in the liver and can cause liver damage. Well Health Canada tested numerous blue-green algae products and determined that ONLY products made from spirulina blue-green algae were not considered a health risk.

If you prefer to purchase from Amazon (also do a price check to compare) I found you this Certified Organic Spirulina from Starwest Botanicals that looks excellent.

This Certified Organic Kelp powder from the same supplier also looks really good (I add 1 tbsp of powdered seaweed/kelp to my horses daily supplements).
