I have been using the "American Health Super Acerola Plus 500 Gram Vitamin C Chewable wafers" for over 40 years off and on when I can find them at a reasonable cost. I discovered back in the 70s upon taking 2 grams daily that I got an extra energy boost from them. I forgot to take them one day and ran out of gas about 10am just working in my yard doing ongoing pick and shovel landscaping projects. Working 8 plus hours a day doing hard physical labor was routine for me and being gassed out by 10am had never happened before. When I figured out the only thing different that day was my missing Vitamin C dose and not believing that would be the difference, a half hour after taking the dose I was back to my full energy self and finished out the day! Don't ask me to explain that! Another discovered miracle health benefit was instant salvation from a Sore throat. For over 3 months I had a very severe ongoing Sore throat that just would not go away. Several "Urgent-Care" trips to Kaiser resulted in their insistence it was a virus, there was nothing they could do, and it would eventually go away on its own! After 3 months I had become desperate. I remembered Vitamin C back then as being touted to relieve a lot of health issues, among them Colds and sore throats. I filled a sandwich bag with dozens of the chewables, and all day long while at work I popped a few of them into my mouth every few minutes like candy. BY THE END OF THE FIRST DAY MY Sore throat WAS GONE AND WITHOUT A TRACE!! I continued that routine over the next week and stopped. My Sore throat never came back, and I have never had anything like that happen again. The only Con is the very high cost through Amazon at 15.5 cents a tablet which is way over twice the 6.3 cents each I have long been paying my normal supplier. Since Covid happened, my regular supplier is always "out-of-stock" with no due date available, but Amazon appears to have no problem keeping them in stock
