For optimal health, your body needs vitamin C every day, not just when you feel a cold coming on. Stay healthy year-round with Vitamin C with Flavonoids by Thorne Research.

Vitamin C with Flavonoids is a 100 percent pure vitamin C supplement with ascorbic acid and a mixture of naturally occurring citrus flavonoids. Widely known as a key antioxidant, vitamin C plays a variety of important roles in our bodies. Not only does it help protect cells from free radical damage, but it may also support collagen stabilization. Without enough vitamin C, there could be poor collagen cross-linkage and weak connective tissue. Its role in collagen and tissue synthesis also makes it important for recovering from wounds.

Vitamin C is also important for the brain, serving as a cofactor for the synthesis of neurotransmitters such as dopamine and norepinephrine. It also influences metabolism, helping to break down carbohydrates, synthesize fats and proteins, and produce cellular energy. And of course, it may help support a healthy immune system, which is why this vitamin has become so famous during cold and flu season.

The inclusion of flavonoids mimics the nutrition of natural citrus fruits, which contain vitamin C and flavonoids. Flavonoids like rutin, hesperidin, and quercetin may offer additional antioxidant support and work synergistically with ascorbic acid to make it more effective.

Taking a cue from the purity of nature, Vitamin C with Flavonoids is free of extra fillers and preservatives like corn starch, magnesium stearate, lubricants, diluents, and bioavailability-inhibiting flowing agents. So all you get is pure, crystalline vitamin C, natural flavonoids, and optimal health support. Think beyond colds and orange juice. Support overall health with high-potency, pure Vitamin C with Flavonoids.

Quality Vitamin C

by AAA

After a different brand changed its formulation, I decided to try Thorne Vitamin C and was generally impressed with the quality of this product. When I’m not feeling my best, I take a capsule of this brand with a glass of orange juice and I feel better quickly. Definitely Recommended.

Great for immune therapy and doesn’t have a nasty aftertaste

by LindaLBKA

I like the fact that these digest easily, and do not have any aftertaste that I have experience with other vitamin products. I would order these again also, there’s no filler, it’s pharmaceutical grade, and digest easily without causing any other issues. Since vitamin C is water soluble, it is excreted in her urine. That’s why you want to make sure you’re getting enough vitamin C and have it taken with iron so you’re getting the most out of it. It competes with junk food with sugars for absorption. I’m very happy with this blend as it allows me to get the most vitamin C compared to other vitamins

Seems Decent

by Antony Steele

Since I do not have Scurvy, or specific blood work, it is hard to tell how effective a given supplement is working. I know that my daily diet does not include enough vitamin C, so I hope this is helping my overall nutrition and dietary health. I think this may be one of many nutritional supplements that has kept me in good overall health for a few years now. I am keeping my fingers crossed.

Good quality


This company is more of a pharmaceutical grade. You can be assured you're getting a good quality vitamin C I have study different companies.
