Product overview                                       

In this product review we are going to be looking at L-Carnitine which is a naturally occurring amino acid derivative that’s often taken as a weight loss supplement. L-Carnitine has been around for a long time, that’s involved with energy metabolism in the body and therefore, many people hypothesis that it can aid in fat loss. RSP Nutrition’s L-Carnitine comes with 120 servings per bottle with one serving being one capsule (i.e. 120 servings per container).

Pros and Cons

RSP Nutrition’s product is entirely stimulant free. This means that whilst other products might contain caffeine, this product doesn’t and therefore, you can take it at any time of the day. The last thing that you want is for your supplementation and diet to affect your sleep as in turn, that can affect your performance and success with your goals.

The downside to this product is that l-carnitine hasn’t been proven to actually aid in the success of weight loss goals unless the individual is already deficient in their natural l-carnitine levels.

Product Description & Benefits

L-Carnitine and Acetyl L-Carnitine (ALCAR) can help to alleviate the effects of aging and disease upon mitochondria as well as increase the ability of these mitochondria to burn fat. The theory itself is good, but the tests specifically on using L-Carnitine for fat loss do not support this claim. However, as it can help to improve your energy levels, it can help to indirectly burn fat as you’ll be burning more calories each day.

L-Carnitine can also help to improve your cognition as some people report feeling more alert. This is most likely due to the additional mitochondrial capacity and support for the neurons within your brain. For this reason, it can also help to reduce the mental decline associated with aging as well as improving the sensitivity of your insulin and the health of your blood vessels.

RSP Nutrition state that their L-Carnitine supplement can “convert fat into re-usable energy” and “increase workout performance” to help you get the results you want. Though, most of the evidence supports its use for health benefits opposed to performance.

Product Specifications

Overall Rank & Review

As a supplement, due to the unproven effectiveness of l-carnitine, this product ranks low in terms of importance. Other supplements will be much more effective and worth your money, such as protein powder, creatine, caffeine, and beta alanine. Using this supplement can be effective in reducing the effects of fatigue and mental performance.
