Optimum NutritionL-Carnitine 500 mg - 60 Tablets

Need to use higher amout of l carnitine for fatloss.

Don't focus in supplements, focus in diet and exercise

I started taking L-Carnitine a few months ago based on reviews and on my success with other ON supplements. Since taking them at the recommended dosage, I have been experiencing severe muscle cramps in my hands daily, and "restless leg syndrome" at night, where my right calve would tingle/tighten. My initial prognoses was that these symptoms were the result of heavy weightlifting and my age. But then I went on a 3 week vacation and opted not to take any of my ON supplements. Within a day or two the cramping and restless leg syndrome stopped and it wasn't until I returned home and started taking my supplements again that these issues returned. So I started researching each of my supplements (BCAA, CLA, Glutamine, and L-Carnitine) and I read that Dr. Oz had retracted his statements on the benefits of L-Carnitine, as there is little to no clinical proof that it helps in weight loss or energy gain, and that continued use of the supplement could lead to health issues. I then stopped taking this supplement immediately. Within a day or two my symptoms were gone.

This finally helped me lose weight after trying everything under the sun {exercise/diet} but couldn't. I was taking 2 tablets twice a day with meals. On days I exercised, I took 4 tablets an hour prior with a meal. It gave me enough energy or endurance for a full hour of exercise, and felt better the rest of the day than if I had not taken it. After only a few months, I was finally able to reach my goal weight.I also took CLA  Olympian Labs CLA -- 3000 mg - 210 Softgels  with food 3 times a day. There are books written by doctors which recommend taking 3-5 grams of L-carnitine an hour before exercise! depending on body weight. L-carnitine is a regular supplement for bodybuilders.Once I reached my goal weight -- overall losing 30 lbs -- I felt that L-carnitine is still worth taking to help MAINTAIN the ideal body weight {only 1 tablet with meals twice a day now}. It's my "secret" to good health. This particular brand is the most potent compared to others -- I've tried most other brands in an effort to "save" money -- so it's a lesson learned, and only buy this Optimum Nutrition brand since.Note that L-Carnitine is different than ALC ~ Acetyl-L-Carnitine which is promoted as having positive effects on memory or the brain. L-Carnitine is a different supplement and works on the mitochondrial cells/body muscles.Update 8/21/2018: These days, I make sure to take L-Carnitine with vitamin C or eat vitamin C-rich foods. Another precaution I found out, it must be taken at least 2 hours away from any thyroid medication, iron, and mineral supplements. L-Carnitine is essential for the liver to work properly [e.g. energy production], and some people could have a deficiency in carnitine.As for the other reviewer stating muscle cramps or RLS, he probably only needed to make sure he's not deficient in essential minerals such as magnesium and potassium. :) Olympian Labs CLA -- 3000 mg - 210 Softgels

It doesn’t work for me. I’ll be back with met-rx, at the last I had got results with met-rx but with this ON l-carnitine I get nothing.
