In what quantity? How much citric acid would you have to take to get 100 mg of Oxaloacetate? Plus, all supplements sold without a prescription in the U.S. have to naturally exist within the body or be in “normal” foods. If resveratrol had proved to have anti-aging properties buying it wouldn’t be a ripoff even though resveratrol is in red wine.
47 grams per liter of lemon/lime juice. That converts to ~25 g oxaloacetate per liter. Oranges apparently have less citric acid, to the tune of perhaps 500mg oxaloacetate equivalent per liter of juice.
Food-grade citric acid (also sold under the name “sour salt”, usually shelved with spices) is FDA-classified as GRAS. Looking at Amazon, the Spicy World Citric Acid in the 5-pound bag is $19.23 (free shipping for me, since I have Amazon Prime).
At the ~2g of citric acid metabolizing into ~1g of oxaloacetate you suggest, that translates to a price of $0.05 per three grams of oxaloacetate, or three orders of magnitude cheaper than buying a bottle of 30 100-mg capsules for $49.
