Key Ingredients: -Organic Broccoli Sprout Powder: Initiates Phase I liver detoxification and activates NRF2 pathways. -Spirulina: A powerful sea green that helps the skin detoxify from everyday chemicals and toxins. -L-Theanine: An amino acid found in green tea that supports a normal histamine response. -Liposomal Quercetin: An extremely bioavailable form of quercetin to target mast cells and help support a normal histamine response. -Organic Chinese Skullcap: A natural herb that supports a normal histamine response. -Organic Irish moss: Supports healthy thyroid function and helps detoxify from heavy metals.

Review: I learned of this supplement from Layla the Boxer's mom. My Cairn has seasonal skin allergies that cause him to scratch and lick incessantly. He is a very picky eater and this product is easy to sprinkle over his food. It must not have much taste, or a disgusting one, because he eats without hesitation. It is very effective and usually calms his scratching/licking in a couple days and ends it in about a week. I only use the product as needed and have ordered it twice in as many years (I think).. I feel it is a good value and keeps him off prescription or OTC allergy medication.
Review: It has been one month and my purebred Rottweiler has shown notable results.

We'll see how this works once the weather warms up but for now, I do think this took the edge off and kept me from having to give my dog daily Apoquel during this past winter. I'm not sure that he loves the taste (it's very green smelling) but if I mix it in with a topper for his kibble he eats fine. My other dog with MCT's wasn't affected by this (good or bad) but since it didn't seem to make a difference for her, I stopped adding it to her food. It certainly lasts longer when only given to one dog! Pricey but overall not a bad product to trial and see if it works for yours.
