After 12 years chronically ill, this HELPED

I’ve tried everything. I mean everything. And when I started this (and later adding h1 and h2 blockers) I actually felt a HUGE difference. Clearly I have mast cell issues because I can actually function now, it’s amazing.

Amazing

I have been taking this product for months. It really helps my health and MCAS symptoms. Bottle is the perfect size and it lasts two months.

Great Product!

I'm unable to take OTC allergy meds because they make me too drowsy or give me a stomachache. My doctor recommend this product for mine and my cat's seasonal allergies. My pets and I have been using this product for several years without side effects. My neurologist also said it's helping with my overall inflammation. The capsules are small and tasteless. It's easy to open the capsules to divide up the dosages if necessary. I've tried several products in this brand and never had issues (I'm sensitive to a lot of things). Highly recommend!

This is a good brand. I am sure it is a good product; however I get pain behind my eyes after taking quercetine ( had the same effect with other brands too). I wanted to try this because the additives are very clean. But it did not work for me.

This is the best

The ingredients are very clean, and the company is trustworthy, so I switched all of my supplements to Pure. They’re a bit expensive, but absolutely worth the price. I highly recommend them.

Anti inflammatory properties

I started taking this to help with allergies. I'm only on the first bottle so I'm not sure of the benefits yet as I think it needs to build up, but I'm hopeful that my inflammation will lessen and it lowers the reaction of my mast cells. It was a bit expensive but I trust Pure Encapsulations for their quality ingredients.
