    Good but can be better as well!

    Posted by Supplementsdiy on Nov 17, 2013

    Acetyl L-Carnitine is advanced form of L-Carnitine works much better than L-Carnitine. Acetyl L-Carnitine improves the immune system, energy production and weight loss by moving your fats to the mitochondria to product energy, is anti-aging by slowing the natural aging process, boosts the brain function and mental energy through numerous ways and shown to slow/reverse neurodegenerative diseases. It’s a powerful antioxidant that is fat and liquid soluble, meaning that it can easily reach most parts of the body, including crossing the blood brain barrier. Unlike most supplements, Acetyl L-Carntine shows its benefits, like better focus and sharpness almost instantly (usually within 1-2 hours). It’s also a good way to show supplement sceptics that supplement works and are impatient to wait for the long term benefits. The price is the most competitive as well.The caps are made of gelatine (not for vegetarian), normal size and easy to swallow. Personally, I find that I no longer have mental fog and can concentrate for a long time. I also find myself remembering names and things that I am suppose to have forgotten more than 10 years! The suggested dosage is 1-4 capsules. Personally, it’s hard for me to recommend. You probably have to try trial and error. For me, 2 capsules daily are just right. 4 capsules tend to cause overstimulation for me. Taking it too close to sleeping time also makes it difficult to fall asleep. Exercising is a lot easier and my timing for running has definitely improved a lot. Weight maintenance is much easier as you get the energy to go for more workouts. I think the only downside of Acetyl L-Carnitine is that once you get so used to the benefits, you will feel very sluggish and more tired if you stop taking it. However, this is no reason to stop taking! Note that the supplements do contain many flow agents or binders etc. Check out my page for more reviews!

    Gives me energy!

    Posted by 5263355940042198385 on Jul 23, 2013

    I am a 37yo full-time working mom with a 31month toddler. I took this as i was facing an increasing lack of energy that is slowly affecting my daily life. I used to feel refreshed and recharged after a good 6-7hrs sleep, but recent months that just didn't work no matter even if i had a straight 10hrs sleep. i immediately felt completely drained out and ready to hit the bed again after sending my gal to the childcare -- that was like 90mins from i last woke up! After some research i decided to give this a try. I took 2caps of this with 200mg of CoQ10 and Omega3 first thing every morning for a month now, and WOW, this does the trick! i no longer felt drained out and am back to my old self again. I'm so happy and relief this works for me!

    I took this along with D-Ribose and CoQ10 for a period of time to help fight my Chronic Fatigue. I believe that together they have put me on a path to better health.

    One of the products my husband takes for a cardiac condition. He's doing well. Appears to be a good product for the price.

    I have combined L-carnitine with L-arginine and alpha lipoic acid along with creatine supplementation and exercise to try to combat the progress of peripheral neuropathy which has led to leg muscle atrophy.
