The Best C I've Tried (And I have tried a lot!!!)
American Health 500 mg with Citrus Bioflavonoids Capsules is the best vitamin C I have used. After dozens of other brands/types, I found one that is gentle on my stomach and does what I need it to do. I cannot provide any official medical evidence that it prevents colds and other illnesses, but for me it works.I take two 500mg Caps at bedtime and an extra one during the day if I feel a sniffle. It does the job. I recommend it.

Great product but cut tablets in half.
After doing a lot of research I decided on purchasing this product because Ester-C has a higher absorbency rate than regular vitamin C, and does not make your stomach as acidic as other products. Also, it has healthy citrus bioflavonoids. According to Livestrong.org,, citrus bioflavonoids help lower cholesterol and triglyceride levels; they make skin more resilient; they have the potential of helping with drug resistant cancer cells making them more sensitive to chemotherapy; they could protect the brain against Alzheimer's disease; and they also might provide protection against heart disease since these type of bioflavonoids work reducing inflammation and improve circulation.The only thing I do not like about this product is the size of the tablets. They are huge and I have to cut them in half to swallow them to avoid choking. But cutting them in half is not a big deal. All in all, I highly recommend this product.Inflammation and Circulation ImprovementPromising research involving patients with metabolic syndrome points to a potential benefit of a citrus bioflavonoid called hesperidin. A study published in "The Journal of Clinical Endocrinology & Metabolism" in May 2011 found that patients given hesperidin had fewer markers of inflammation in their blood and improvements in endothelial function, or the functioning of the lining of their blood cells, and thus in circulation as well. These improvements may also lower heart disease risk.

Gentle on the stomach.
These are a nice way to take a daily Vutamin C. It's Ester c and it won't upset your stomach or give you the runs which sometimes happens with other formulas.

Clear capsule
Powder inside a clear capsule. Cant use chewable and others are too large to swallow. This allows for easy swallowing or open to add to food.

Really has an energizing effect.
I've been using this product for decades. It wonderful and does not upset the stomach in any way. I couldn't take Vitamin C supplement until I noticed these. Very energizing. My only issue is my last order came unsealed. I'm going to go ahead and use them, but wouldn't recommend it for customers.

Helps reduce back and joint pains
I take 1000 mg (1 gram) of this product twice per day. How much you may need may vary according to your weight and other factors. I am a male who weighs 185 pounds. The 500mg capsules are the best value. I do not recommend the caplets/tablets, as I have not had as good of results with them. I began taking Ester-C after reading articles about how it was used to help improve the lives of large breed dogs that had hip dysplasia problems. At the time I was suffering from a lot of lower back pain, and I did not want to take typical OTC pain relievers. I found that it takes 2-3 weeks for this product to begin to alleviate pain. For me, it truly has reduced pain! I have also learned from my experience, that if you discontinue the use of the Ester-C, the pain returns in about 2-3 weeks. So, it apparently has some residual qualities. If you take too much it will cause the runs, so be forewarned! While I primarily take Ester-C for back pain, it does also help with hip and other joint pains. My primary, go to, supplement for arthritic joint pains is Boswellia Extract (I use Nature's Answer brand). Taking the Ester-C and the Boswellia Extact in combination leaves me feeling as nimble as someone much younger than my 55 years old. I am hoping to avoid the pain and mobility issues that are now crippling my aging father. So, I will continue to take and recommend these products. I believe that Ester-C has many other health benefits, but the pain relief is the most noteworthy one IMHO. I have experience zero negatives, other than it can cause the runs (as mentioned previously). I recommended it to my sister, and it has helped reduce her joint pains too.
