I usually take one of these a day. And sometimes when I feel like I'm starting to get sick, I take them 3 times a day like you would an antibiotic. Haven't been badly sick in 10 years; used to get sick 3 or 4 times every winter with COPD exacerbation.

I take it pretty regularly, but when I'm sick I take it 3 times a day like you would an antibiotic. I have COPD. It works for me. I like the time release, as it's active in my body longer. I do burp usually once when I take it, but no garlic taste. I try to purchase when there's a sale.
