I have used "Kyolic" brand garlic supplement for many years now because I believe it to be very much effective for my personal use. It is odorless, does not cause uncomfortable "Burping", leaves no after taste, is very reasonably priced .. is an older brand of garlic supplement, I trust it implicitly, My doctor has approved it for my use, I would never buy another brand of garlic supplement as long as Kyolic is available to the markets.
