Male adults over 40 might have noticed a decline in their energy levels, difficulty in maintaining lean muscle mass, and an expanding waistline despite regular exercise and a controlled diet. Additionally, lower libido and erectile dysfunction could also be evident. This change can be attributed to the declining testosterone levels that come with age. The hormonal imbalance due to this phenomenon affects men’s mood, energy, and libido, and is called “andropause.”
The Role of Carnitine
Carnitine is derived from an amino acid and is present in the body’s cells. Its decline contributes to the aging process. Found mainly in the mitochondria, carnitine helps deliver fatty acids, boosting energy and muscle strength while increasing certain enzymes needed for breaking down carbohydrates.
Supplementing with carnitine can help boost energy and strength, combat fatigue, depression, and erectile dysfunction, and promote sexual health, all without the side effects of testosterone therapy.
Carnitine Studies
Many studies have been conducted on carnitine, proving its effectiveness in dealing with age-related issues. Some noteworthy studies include:
- A study with 130 men between the ages of 60 and 74 saw researchers comparing carnitine with testosterone therapy. After six months, while both improved sexual performance, carnitine proved more effective and did not increase prostate volume like testosterone did. Additionally, both testosterone and carnitine successfully addressed fatigue and depression.
-
Supplementing aging rats with carnitine and an antioxidant called alpha-lipoic acid reduced mitochondrial decay. The animals exhibited improved memory and increased activity. This indicates that using acetyl-L-carnitine (a form of carnitine) may enhance mental function and slow down deterioration in those experiencing mild cognitive impairment and Alzheimer’s disease.
-
A study on cancer patients revealed that carnitine supplements could alleviate fatigue while improving sleep and depression.
How to Take Carnitine
Carnitine supplements include L-carnitine, acetyl-L-carnitine, and propionyl-L-carnitine. These are available alone or combined with other ingredients in men’s health formulas. A popular ingredient in male health formulations, acetyl-L-carnitine features in EveryDay Male®, a daily supplement by Prostate Research Labs containing 13 ingredients designed to support aging men’s energy, libido, and strength. However, it is important to consult your doctor before starting any supplement program.
Be aware that high doses of carnitine (over 3 grams per day) may cause side effects such as nausea, diarrhea, cramps, and a fishy body odor.
In conclusion, carnitine can be a safe and effective way to naturally boost testosterone levels without resorting to testosterone therapy. So, for men over 40 experiencing the physical changes brought on by lower testosterone levels, consider adding a carnitine supplement to your daily routine.
