NAC at Costco on sale - too good to be true?
Hey folks, spotted NAC at my local Costco for like 40% off. Usually I get the NOW brand from Amazon, but this is a store brand. Anyone tried it? Is cheaper necessarily worse quality? Seems like a steal but I'm wary.
I use NAC almost daily for my sinuses. Got the Kirkland brand from Costco once and it seemed fine - same active ingredient. Check the dosage and additives. Usually store brands are made in same facilities as name brands. I'd say go for it!
Ellen! I'm new to NAC so I can't help much, but I read that bioavailability matters more than brand. Also, some people get upset stomach from cheap fillers. Might be worth checking reviews on their site? Let us know if you try it!
Thanks Steve and Greg! I'll check the label for any junk. Maybe I'll grab two bottles and do a side-by-side with my NOW stuff. If I don't notice a diff, it's a win.
