Rated 5 out of 5 by Clancy A balanced ascorbic acid formula.
A good balance of ascorbic acid and bioflavonoids at a great price.
A very complete combination of the essential antioxidants for cellular protection and assisting to keep vitamin E from contamination.

Rated 4 out of 5 by StephenX A good mix of ingredients
Vitamin C is not just ascorbic acid. This supplement has bioflavonoids, hesperidin and other ingredients to make this a complete formula. My only gripe is with the fillers.

Rated 5 out of 5 by MarathonMan Best "C" option
Vitamin C is soooo important you want to be sure you consume the very best combination of high quality sources. Ultra C is the best mix of sources at a really great price. The capsule form ensures quick absorption.

This is a healthy dose and a good sized capsule. A nice alternative to tablets.

Rated 5 out of 5 by thebump1966 Ultra C Formula is the best C
We love that this C is in capsule form. It's much easier to take than compressed tablets and we feel it is more effective because it is more available. Also we find the price better than most retail stores. And because we cannot find the powdered form in capsules available at any local stores, Swanson is our goto provider.

Rated 5 out of 5 by SMGen A basic cannot do-without supplement
This is one of our favorite Swanson supplements. It is in our desired potency, 500 mg. It is combined with ingredients that enhance its availability. Because of its small size, it is easy to swallow. It dissolves quickly and we can take it any tine of the day or night without a problem. It is a great price. My husband and I have used it for quite a few years.,

What I like about Ultra C is that it contains not only Vitamin C, but also several other helpful ingredients so I get just a little more bang for my buck!
These capsules are very easy to open up and the vitamin c can then be added to smoothies.

This is a great Vitamin C product. I like the additional ingredients that work with Vitamin C. The capsules are smaller than Swanson's Supreme C Complex. Great value for a great price!

I bought this because it contains all the bioflavinoids, rutin and hesperin. I know it's the combination of these items that help my immune system stay strong.
