NSI L-Carnitine Fumarate -- 500 mg - 300 Capsules

NSI L-Carnitine Fumarate -- 500 mg - 300 Capsules

Heart and Muscle Health! L-carnitine fumarate helps to facilitate the transport of fatty acids through the inner mitochondrial membrane (so these fatty acids can be oxidized for energy). A major cause of aging is the deterioration of the energy-producing components of the cell, which results in reduced cellular metabolic activity, the accumulation of cellular debris, and eventual death of the cell. Since L-carnitine is a fat metabolizer, it may be useful with weight loss. Did You Know? All NSI supplements are packaged in HDPE (High Density Polyethylene) bottles. These bottles keep moisture vapor out, protecting the freshness and integrity of their contents, and are 400% more effective compared other brands currently using PET (Polyethylene Terephthalate) bottles. HDPE bottles do not break as glass can and are also recyclable so we urge you to please recycle them.

"There were a few broken capsules in the bottle and that has made all the other capsules extremely salty. Also, if I take more than two capsules at a time, my face and ears start to flush - the flushing lasts for a few hours and is a little annoying."

"I have had other brands of L-Carnitine and I really felt the difference of my energy level when I took it for couple of days. My family takes it too and it had the same effect on them also.
The NSl L-Carnitine somehow did not leave the same effect at all on any of us."
