What it is
Ascorbic acid with bioflavonoids. 180 capsules, $30 — about 17 cents each, which puts it among the cheapest things in this catalogue.
Why people consider it
Vitamin C is one of the few supplements with an unambiguous case for existing: humans cannot make it. We lack a working copy of the enzyme that lets most other mammals synthesise it from glucose, which is why it is a dietary requirement rather than an optional extra.
Beyond that, one practical fact is worth more than most of what is written about vitamin C: it substantially increases absorption of non-heme iron — the iron in plants and in most supplements. That is useful if you are trying to raise iron, and worth knowing if you are trying not to.
What makes this one worth a look
It is the plain form, and that is a deliberate choice rather than a cost saving.
There is a long-running marketing argument that “whole food vitamin C” is superior to ascorbic acid. The straightforward response is that ascorbic acid is the molecule the clinical literature studies. When a trial reports on vitamin C, it is almost always reporting on ascorbic acid. Choosing the plain form means choosing the studied form, and it happens to be much cheaper.
The bioflavonoids are a reasonable addition — they occur alongside vitamin C in food. We cannot tell you which ones or how much, because the listing does not say.

Who it may suit
- You want plain ascorbic acid rather than a "whole food" complex, and you want it cheap.
- You take vitamin C alongside iron and want the absorption benefit.
- You go through vitamin C quickly and want a high count rather than a premium presentation.
Less of a fit if…
- You specifically want a food-derived vitamin C such as acerola or camu camu. This is not that.
- You need a known milligram dose. It is not published on the listing.
- You are sensitive to ascorbic acid on an empty stomach — that is a real thing for some people and a buffered form suits them better.
