## Description

Acetyl-L-Carnitine (ALC) is a nutrient that occurs naturally in the body and is fundamentally important for energy generation by the mitochondria energy factories in our cells. The acetyl part of the molecule can be used to make acetylcholine, a key chemical messenger in the brain and all the other organs. ALC also is involved in regulating gene activity (epigenetics) and is a versatile protective nutrient for the nervous system.

## Questions & Answers

**Q: What is the difference between this supp and  doctor's best best l-carnitine fumarate featuring sigma tau carnitine (855 mg) vegetable capsules  ????**
A: According to the research I read, Acetyl L-Carnitine is a form that passes through the blood-brain barrier providing the neurological health effects whereas L-Carnitine Fumarate or Tartrate do not. People take Acetyle form for neurological benefits and the other forms for fat metabolization, increased energy, and other whole body effects. Fumarate and Tartrate forms do not cross the blood-brain barrier.

**Q: Expiration date if I purchase now?**
A: Mine is May 2018

**Q: Made in china or italy? reviewer states china, doctor's best  web site states "contains biosint acetyl-l-carnitine, which is manufactured in italy"**
A: Rome Italy. Manufactured for Doctor's Best.

**Q: Magnesium silicate is talc!!!?**
A: You would have to contact the company. I no longer use this product. It is not enteric coated capsule, and causes severe indigestion. I actually make my own from bulk supply. I get it through Bulk Supplements, and make my own capsules. Once I made the plunge and have learned how to do it, it is quite easy. I make them 100 at a time and it takes about 1/2 hour from time I set it up to done. And all for about 35 cents for a hundred. And NO added fillers, including talc! All the best and to your health. Oh, yeah? I take It help with polyneuropathy.

### ⭐⭐⭐⭐ Has been helping my fibromyalgia-related issues...
*by I***L on November 5, 2017*

I have fibromyalgia and am always looking for things that will provide any help at all - for pain, for muscle issues, or for mental acuity to combat "fibrofog." I know that sometimes meds / supplements that help one person with fibromyalgia may not be effective for others, but this has been working for me. I am in my fourth week of taking this and I have already seen a difference (I generally do 6-week trials). My pain levels have been a little lower (every little bit matters!) and my tolerance of activity has improved (which I guess for normal people might translate into "more energy"). I have felt a little sharper mentally as well. Have not noticed any side effects. Recommended dose is two pills with a meal (or up to four with two meals). The capsules are not tiny - 7/8" long and a uniform 1/4" in diameter, which is why I've docked it a star - but they're not the biggest pills I've ever seen (or even currently take), either. I've been taking one with breakfast and two with dinner. Came back to re-order!
