I work in healthcare and in schools, and am always around little kids who are sick with something (some have been superbugs like MRSA, Whooping Cough, and Entero), but I haven't caught anything in the two years since I discovered this wonderful brand. Vitamin C kills virus replication, highly recommend you try this stuff! I take 1,000 - 2,000 mgs a day during the summers, but in the winter months when everyone is sick and I'm working like a maniac, I bump it up. With this stuff you can do that without stomach upset like you/I get with other brands. The few times I've run out and not replaced it, my immune system is nowhere near as strong as it was and I start feeling like I'm fighting every bug I'm exposed to. I start back up with this brand and whatever I was fighting disappears quickly (not true with the others, or they give me gastric distress). If I think I'm fighting something (like when my kids came to stay and all had an awful flu), I bumped it to 3,000-5,000 mgs/day and took care of them, and didn't/still don't catch anything from anyone. This has happened more than once and this is the only thing that has been different. Truly an EXCELLENT product!

I have been taking this stuff on faith for several years now, because someone I trusted recommended it. Never could tell any difference with it but since I believe in vitamin C, I kept taking it.<br /><br />However, I have recently had occasion to test this stuff as I battle a very virulent and stubborn sinus infection.<br /><br />IT DOES NOT WORK.<br /><br />I ran out of this stuff in the course of my sinus infection and had to turn to ascorbic acid for several days as I waited on a delivery. To my surprise, I found that an equivalent dose of ascorbic acid gives a startlingly, significantly better boost to the immune system. The efficacy between the two products is noticeable, as is the time it takes to see benefit. Ascorbic acid works very quickly. If this stuff works at all, it takes forever.<br /><br />There is a noticeable difference in reduction of inflammation and swelling when I use ascorbic acid, compared to this product. 2000mg of ascorbic acid brings some relief; this stuff...nothing.<br /><br />I'll use up my bottle of this, one cap at a time, for the bioflavinoids. After that, I'm never buying again. Just cancelled my autoship.<br /><br />In a perfect world I'd be able to afford to use liposomal vitamin C (that stuff REALLY WORKS) but if you can't afford that, skip this and &#34;devolve&#34; back to the old Linus Pauling stand-by, ascorbic acid. Much more bang for your buck.<br /><br />This product is ineffective. Don't bother with it.

This is the best Vitamin C on the market. Used regularly it seems to keep you from ever getting sick. My family uses this daily and has for many years. Fantastic product.

I Keep Buying Metabolic C -and combine it with other brands with higher dose or time release -as part of a regular somewhat high dose C regime which I've identified over the years as having a number of varying noticeable positive health effects for me (and part of an evolving overall herbal and plant based whole foods diet.) I'm not certain but my thought is the metabolic C is absorbed for sure and if I didn't take it I might look for other Cs brands - and dose and frequency. On the other hand I might not take metabolic C alone. Possibly expense or the thought of combining best of several approaches - buffering bio-flavonoids - for effectiveness and economics. Whatever. It's been a regular part of my program since I found out about the absorption issue. Ergo. The review.

Great type of vita C - can open capsules and add to morning shake. This one a YES!

Loved it
