The worms were in a medium of 100 uM (23 mg/l = 23 ppm) and the agar for the flies were the same. This is equal to the low dose fish group that showed no benefit and 25 times less than what the high-dose fish. Based on dose per calorie consumed (23 ppm) this would be only 23 mg RESV for someone who eats 1 kg per day of food. As shown in previous post this dose/calorie method overestimates what the FDA and EPA consider the human equivalent dose. The worms lived 14% longer and the flies lived 18% longer.
The yeast work showed big benefits at 10 uM (2.3 ppm) and saturation around 100 uM (23 ppm), but I don't think this is in terms of food consumed, so I can't compare.
So it seems the fish study is the only one that can show relevance to humans taking more than 23 mg/day.
