A very good quality vitamin C, with mixed ascorbates as the ingredients. The size of the tablet is a little large, but the mg in it are great and potency great. Certainly helps with immunity. No taste to it. Not harsh on the stomach, no acidity. The effect would be cumulative.
I really like that this contains zinc ascorbate.. if you search for this and covid it acts as a zinc ionophore and helps get zinc inside the cells. Also I had read that it might be best to take on empty stomach followed by full glass of water (to reduce stomach acidity and help it get into small intestine quicker for better absorption) possibly followed immediately by a meal (to further reduce acidity) - unsure how all that works but just stating what I recently learned. For those looking for both C and zinc this is a win (and I like how it also includes some other minerals and ascorbates like manganese etc but for the zinc its at 200% so is very good. I can't swallow pills so I have to chew it up (it is pretty bad tasting) but I'm used to that. If not using the zinc ascorbate you can also use quercetin with other forms of zinc to help the zinc get into the cells. I have both now that I found this. But if this doesn't work for you then look for quercetin and the kind of zinc that you like best.
The form of this vitamin C is the closest form of fruit and vegetable vitamin C.
You will never find pure ascorbic acid in nature is always under ascorbate form.
This formula has no sodium at all as well which is another good thing, all the vitamin c buffered are under the form of sodium ascorbate which can be a problem for restricted sodium diet.
Does not irritate the stomach. In addition to most vitamin C, it contains good trace elements, but is also more expensive. It's confusing that the concentrations are not indicated per tablet but per serving.
