Each vegetarian capsule gives you 500 mg of vitamin C from calcium poly ascorbate (which also supplies 57 mg of calcium), plus 100 mg of citrus bioflavonoid complex, 50 mg of hesperidin and 50 mg of rutin. There are 60 capsules per bottle.

In Good C, the vitamin C comes as calcium poly ascorbate, a buffered form in which vitamin C is bound to calcium as a mineral salt (a calcium ascorbate) instead of being a free acid. That's why the bottle says acid free, and it's where the 57 mg of calcium on the panel comes from. That calcium is a small extra (4% of the Daily Value), not a calcium supplement.\u003c\/p\u003e\n\u003cp\u003eDoes the form change anything inside your body? Early evidence says possibly, a little. \u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/39408325\/\"\u003eA 2024 preliminary study comparing calcium ascorbate with ascorbic acid\u003c\/a\u003e ran two small crossover trials in 93 healthy adults, one at 250 mg and one at 500 mg, giving each person a single dose of both forms. At 250 mg there were no differences. At 500 mg, compared with ascorbic acid, calcium ascorbate raised blood levels of dehydroascorbic acid (an oxidized form of vitamin C), increased neutrophil activity over the first 8 hours, and was linked to more natural killer cells.† It tested single doses of calcium ascorbate in general, not this exact ingredient, so read it as an early signal rather than proof.\u003c\/p\u003e\n\u003ch3\u003eHow much your body actually absorbs\u003c\/h3\u003e\n\u003cp\u003eYour gut absorbs vitamin C well in moderate amounts and less efficiently in big single doses. In \u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/8623000\/\"\u003ean NIH study of vitamin C absorption in healthy volunteers\u003c\/a\u003e, 7 people lived in the hospital for 4 to 6 months on a diet with less than 5 mg of vitamin C a day while researchers tested seven daily doses from 30 to 2,500 mg. A single 200 mg dose was completely absorbed. At single doses of 500 mg and higher, the share absorbed dropped and the extra was passed in urine. White blood cells were saturated at 100 mg a day. At 500 mg, each Good C capsule is in the range where absorption starts to taper, so if you take more than one, spread them across the day. More isn't automatically better.\u003c\/p\u003e\n\u003ch3\u003eCitrus bioflavonoids, hesperidin and rutin\u003c\/h3\u003e\n\u003cp\u003eBioflavonoids are plant compounds that come packaged with vitamin C in citrus fruit. Good C includes 100 mg of a citrus bioflavonoid complex plus 50 mg each of two specific flavonoids: hesperidin, the major flavonoid in oranges, and rutin, which shows up in foods like buckwheat and citrus.\u003c\/p\u003e\n\u003cp\u003eHere's what the research does and doesn't show. \u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/24169506\/\"\u003eA review of synthetic versus food-derived vitamin C\u003c\/a\u003e, which also looked at vitamin C taken with isolated bioflavonoids, found no differences in steady blood levels in human studies, and only small, brief differences in some short-term ones. So don't count on the flavonoids in Good C to boost absorption. We also haven't found good human trials of hesperidin or rutin taken at 50 mg a day, so we don't claim a specific benefit for either one at that amount.\u003c\/p\u003e\n\u003ch2\u003eHow to take Good C\u003c\/h2\u003e\n\u003cp\u003eDirections from the label: \"One or more capsules daily, as a dietary supplement.\"\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTake it with a meal, ideally one with plant foods, since vitamin C helps your body absorb their iron.†\u003c\/li\u003e\n\u003cli\u003eIf you take more than one capsule, split them between meals.\u003c\/li\u003e\n\u003cli\u003eCount all your sources.
