Plasma Trimethylamine-N-oxide Following Cessation Of L-carnitine Supplementation In Healthy Aged Women
Notes for this study:
||10⁹·L⁻¹. Mean and SEM. At end of supplementation. Placebo: 1.8 ± 0.2 Carnitine: 2.0 ± 0.2
|Number of Subjects
Eighteen female participants visited the laboratory after 24 weeks of taking 1500 mg of L-carnitine-L-tartrate or isonitrogenous placebo per day. They returned 4 and 12 months after cessation of supplementation for more testing.
The carnitine group saw substantially higher TMAO concentrations by the end of supplementation, which reverted to the placebo levels after 4 months. There weren't statistically significant differences for blood lipids, though. Levels of immune cells weren't statistically significantly different.
