If not 100%, then I am sure the majority of the Garlic supplement available in the market are nothing but a waste of money. Garlinex is a real deal, and it’s not just a supplement; it’s whole garlic in the capsule. Shipment cost me a lot (to Hong Kong), but its worth it. Using it for the last 4 years and will not stop. I was pretty easy to catch a common cold and flu, but since I started to take Vit C and Garlinex and some exercise, I am healthy, cold and flu-free for years.
