Description
In patients with chronic kidney disease, reduced reabsorption of carnitine can affect the availability of carnitine in muscles, leading to skeletal muscle atrophy and decreased exercise endurance [262]

Diagnostic Methods Diagnosis typically involves measuring plasma carnitine levels and identifying mutations in the relevant genes through genetic testing

In Japan, for example, it is 1 in 40,000 births [63], while in China it is as high as 1 in 20,000 births, as a large 2024 meta-analysis involving 10 million newborns demonstrated [66]

One other case study reported similar pain-reducing benefits of D-ribose supplements in a woman with fibromyalgia, but research in this area remains limited ( While some results are positive, the existing research on D-ribose supplements in pain disorders is insufficient to draw any definite conclusions

This occurs because unabsorbed carnitine in the gut can be metabolized by intestinal bacteria into a compound called trimethylamine (TMA), which is then excreted through sweat and breath
