Figure 4. Forearm blood flow responses to acetylcholine (ACh) in the absence (dark grey bars) vs. presence (light grey bars) of the antioxidant, vitamin C, at baseline (base) and following 12 weeks of trehalose and maltose supplementation in the subset of subjects who maintained body mass within 2.3 kg. AUC, area under the dose response curve. Values are mean ± SE; *P<0.05 vs. baseline of same group; ‡P<0.05 vs. forearm blood flow to ACh in the absence of vitamin C at the same time point.
