Another good product at excellent price. This was the first ALCAR supplement I bought. - - - - - - - - - - - - It is extremely safe(Carnitine supplementation has an excellent safety record. Doses of 2-6 grams per day over a period of 6 months have been studied with no observed adverse side effects.) and the benefits are numerous - Acetyl-L-carnitine is a precursor of acetylcholine and improves cognitive performance, ameliorates age-related deficits, preserves, at least partially, learning and memory from the natural decay occurring with age, rescues aged neurons by increasing their responsiveness to neuronotrophic factors in the CNS and lot more.... Recommend this product. 5 stars.
I am already taking B12, iodine, and a B-complex for very low energy. Within a few days of adding 1000mg (2 capsules) of this acetyl-l-carnitine in the morning, my energy starting improving. If I also take 500mg in the afternoon, mu fatigue is even less.
Definitely does something

This provides quite a strong mental sharpness and alertness which for me also gave some slight nausea. I also took around noon and found myself greatly alert all day and then couldnt sleep for much of the night. Half a capsule works much better for me. It also makes me feel like I have just been exercising I suppose since it apparently it increases the mitochondria activity in your cells. Doesn't do much for my autistic kid. Slight improvement in anxiety I think. Well at least it definitely does something unlike much of the iherb stuff. I'm not sure if its really that useful for solving any problem other than tiredness.
Seems good for memory

Have been taking this (am 73 years old) for about3 months and it seems to be helpful.
MOOD ENHANCER plus other benefits!

I originally purchased this when our sons doctor suggested it for him. Our seven year old has autism and this has helped his focus and concentration. I started taking it for brain fog, mood swings and low energy. IT WORKS! I've only been taking one capsule per day and I can feel a major difference in my energy level and mind set. Overall, I feel more grounded, focused and less scatter brained. My mood is better, and there's much less yawning mid day for me. My husband started using this for low energy as well. Two capsules or even 3 seem a better fit for him. It took just 2-3 days for me to feel the effects. The only down side is if you forget to take one, or you run out for awhile, you will feel it! Highly recommend!
Maybe I don't need them?

I've notice no difference in me, taking these. I'm trying a different brand/formula next.
