Product Information

Carnitine and its derivatives exist in a carnitine “pool” in the body. Cellular enzymes and transporters rapidly convert the carnitine to the required form and transport it to the tissues. Carnitine and its derivatives play a key role in fat, carbohydrate, and protein metabolism and energy production and are critical components for mitochondrial metabolism. Acetyl-L-carnitine (ALC) is the most important derivative of carnitine and occurs naturally in the body. Because ALC is considered to have greater bioavailability and is therefore more able to cross neurological membranes, it is the preferred form to take for promoting neurological health. 

The levels of carnitine and its derivatives are critical to normal biological functioning. Carnitine is present in the diet in red meats and dairy products, and humans can make carnitine from the amino acids lysine and methionine. However, carnitine deficiency can occur with metabolic disorders, and in conditions such as diabetic neuropathy (nerve pain) and other complications of diabetes. 

ALC has been studied in various conditions including neurological and cognitive disorders such as Alzheimer’s, dementia, depression, neuropathies, and cardiovascular disease, as well as with respect to the fatigue and pain associated with conditions such as chronic fatigue syndrome and sciatica.

Main selling features

  • The most important derivative of carnitine, and the preferred form to take, as it is the most bioavailable
  • Able to cross the blood-brain barrier
  • Has many neurological benefits, including cognitive ability, memory, and mood
  • Naturally occurring nutrient, free from toxic effects

How it works

Acetyl-L-carnitine is the most abundant naturally occurring derivative of carnitine. ALC helps the body produce energy at the cellular level; regulates carbohydrate, lipid and protein metabolism; facilitates fatty acid entry into the mitochondria; and maintains the homeostasis of coenzyme A. ALC also displays potent antioxidant effects and supports repair mechanisms. ALC has been shown to support heart and brain function, muscle movement, and numerous other body processes. 

ALC protects and enhances the activity of neurons and transmitters in the mitochondria and reduces oxidative stress. By improving cellular function and effi ciency in the mitochondria, ALC stabilizes the fl uidity and function of cell membranes, and improves energy production. ALC is involved in peripheral nerve regeneration and has shown promise in improving neuropathy. Because ALC is able to cross the blood-brain barrier it is able to exert its neuroprotective effects in the brain. Studies have shown ALC can improve cognitive performance and mood by protecting against oxidative stress and reducing or blocking the neuronal death that occurs with dementia and other neurodegenerative conditions. 

Supplementation with ALC may be useful in a broad range of conditions, including Alzheimer’s, dementia, age-related memory loss and depression, fatigue, diabetic neuropathy, and cardiovascular disease.

An Excellent Resource for Understanding Gifted Creative Rebels
Format: Kindle
This book is a gem, filled with affirmations for the fresh genius that an Otrovert naturally brings into the world. The book validates all the ways I have come to understand my own worth in the world, and potential for using my insights to help others in the future. If every person learned to strengthen the muscles of inner awareness, Otroverts would naturally emerge as natural leaders and mentors for a kinder future. I have been a mentor for adults for 40 years and will add this to my toolbox, as an Otrovert myself. Please read this book.

There All Along
Format: Kindle
It all came about on a recent trip to Mexico after my wife of ten years forwarded an article about Dr Kaminski’s discovery of a new personality type. Interested, I dove in to find everything that I read resonated deeply. I looked up the book and bought the Kindle version and it’s been un-put-down able since. My life hasn’t been without a struggle here and there. The short version is that I put myself through Boise State in their accounting program, did well, and then graduated in ‘89. Don’t laugh, my parents thought it would be good if there was an accountant out there with “personality.” It was a bad idea but I didn’t want to do something beneath me like paint houses or be a mechanic. So I gave in. There was an immediate price to pay. My long time girlfriend broke up with me because she wanted us to be more and I felt I had to focus on school and work. I had decent grades despite my shattered heart and my professors were fairly supportive of me. I received an attractive offer to work in a regional firm but it turned out I not only didn’t like the work but even worse, I couldn’t do it. In practice nothing made sense. Balance sheets wouldn’t balance. Income statements wouldn’t reconcile with sales and closing the books was hell. It all seemed so unlike the problems in my textbooks. So I continued working in the grocery store for a few more years. Then in 1992, I met a girl, you know “the one.” Because she was pretty and actually returned my call, I had to have her like she was a possession. So we dated and got married and I sat for and passed the CPA exam and went on to work as an auditor for the State of Idaho which is a lot of fact checking and report writing. In true fashion I tired of the politics and mostly just having a boss. Time marched on. We had kids. She knew she’d found her sucker. I quit my job, opened a private practice specializing in bookkeeping and taxes, neither of which I was very good at. I was good at trying to keep my infinitely narcissistic wife happy keeping up with the Joneses and all the appearances. Through utterly pathetically and foolish means. I got in over my head and embezzled from a client which was discovered although I was never prosecuted, which I correctly predicted. So it’s complicated and I always wondered why I would do such a thing. The answer is elusive, and obviously it was an unbelievably stupid thing to do but I feel I did it either as a cry for help or because I thought my ex wife was worth doing something so wrong. I think I wanted to get caught so I could get my life right at some point. I’ve gone with the cry for help answer because no one is worth stealing for. After $75,000 in child support (which was artificially high due basically to what amounted to extortion from my lovely ex wife - she found out I embezzled to hang on to her then weaponized it against me) and repaying the client I stole from, I started working as a solo painting contractor and never looked back. Life got good for me after I straightened out and became who I am. My second wife believed in me and supported me unconditionally. We’re retired now and are moving to Mexico this summer. 2026 I’m now 61, took the test, my score 227/280. Undeniably an Otrovert.

Life changing and immensely comforting
Format: Kindle
A well written and descriptive book on a topic that I had never seen before but described me to a T. This book lead to great clarity about why I feel the way I do, how to embrace the positives, and best of all, how to navigate a world where I am different from most through peace and empowerment. An excellent read even if these traits don't apply to you, as understanding the inner workings of others and allowing each to be his/her own person is where we learn to live in harmony. Excellent book.
