Acetyl-L-carnitine's mixed effectiveness
We examined how acetyl-L-carnitine affects stress responses in rats exposed to cold swimming. Over ten days, we compared the effects of two stress types and found that cold-swimming significantly increased beta-endorphin levels in both the pituitary and plasma. Notably, acetyl-L-carnitine treatment appeared to offset these changes induced by cold stress. However, it’s essential to highlight that while there were improvements observed with acetyl-L-carnitine, the overall effectiveness for treating cold-related symptoms remains uncertain based on these findings.

ALC maintains testosterone under stress
This study explored the impact of stress and acetyl-l-carnitine (ALC) on hormone levels in male rats. We found that chronic swimming stress decreased reproductive hormones and testosterone levels.

However, ALC treatment appeared to counteract this decline, helping maintain testosterone during stress. This suggests ALC may play a protective role against stress-induced hormonal disruptions.

In contrast, ether stress did not show the same effects on testosterone, highlighting the unique responses to different stressors.

Prevents illness
This medication should be taken at the first sign of a cold or after contact with a sick person. It helps prevent illness, and I would prefer to take it regularly, but it’s rather costly.

Enhanced recovery post-cold
Carnitine is essential not only for sports but also during recovery after a cold. I began taking carnitine after suffering from a coronavirus infection when I felt weak. After 1.5 months of 500 units daily, I regained my previous energy and felt revitalised!

Effective for weight loss

Stay warm in winter and lose weight by sweating in summer! When I took acetyl carnitine in winter, I didn't feel cold at night. In summer, I noticed a significant increase in sweating. It seems effective for weight loss. I no longer feel drowsy upon waking; I feel truly alert.

Improved cold tolerance
5 people found this helpful
I believe there is an effect! I started taking it and found it easier to sweat. Last year, at my workplace in cold weather, I felt chilly even in midsummer. This year, however, it feels just right. I've even asked my colleagues, "Have you been feeling cold recently?" I plan to continue since my body feels slightly tighter.

Better muscle performance
4 people found this helpful
For my diet, I've been drinking it before exercising. I notice a fat-burning effect with carnitine, likely because of my muscle increase. My sensitivity to cold has also improved, and its high concentration seems beneficial for mitochondria, which might mean it works well in multiple areas.
