摘要：Serine, a non-essential amino acid, has attracted clinical attention because of potential benefit in certain metabolic and neurological disorders. Despite the therapeutic potential, little is known about the pharmacokinetics of l -serine metabolism in humans. Here we present pharmacokinetic data at the time of treatment initiation as well as plasma serine levels during dose escalation from a single individual taking oral l -serine as part of a treatment regimen. Our results show that plasma serine levels rise and fall rapidly after oral l -serine intake, suggesting that the optimal dosing for oral l -serine supplementation is at least three times per day.
