L-Carnitine 500 mg, 30 vcaps

Mitochondria, the powerhouses found within human cells, produce the energy that vital tissues need to keep us vibrant, healthy, and young. Normal levels of carnitine support optimum functioning of mitochondria. The problem is that over time, those normal levels of carnitine diminish in all of our tissues, reducing cellular energy production and metabolic activity—a major cause of aging.

Questions and answers:

Asked on: August 28, 2013
Question: Can taking L-Carnitine cause darkend stool?
  • A: We are not aware of L-Carnitine fumarate causing black or dark green stools. Black stools can be caused sometimes by iron supplementation and the foods we eat but only your doctor can provide you the exact reasoning behind that change. Green leafy stools can happen alot when you eat alot of green leafy vegetables but to be sure you may want to talk to your doctor.
