GAT Sport L‑Carnitine

What it is:

• GAT offers a supplement labeled “L‑Carnitine” (often “GAT L‑Carnitine”), typically as 60 vegetable capsules. 

• According to some listings, each capsule contains about 500 mg of L‑Carnitine tartrate. 

• The product is marketed as a stimulant‑free fat metabolism / energy‑support supplement, not a stimulant like caffeine. 

What It Claims / Potential Benefits:

Based on what the brand or sellers claim — and what is known about L‑Carnitine:

• Supports fat metabolism / fat‑to‑energy conversion — L‑Carnitine helps transport fatty acids into mitochondria to be used as energy, which might aid fat burning when combined with training / calorie control. 

• Helps with endurance and energy, particularly during aerobic or mixed training — possibly beneficial for cardio or long workouts. 

• May support recovery and reduce fatigue post‑workout, by improving energy utilization and possibly reducing muscle “burn.” 

From broader studies: L‑Carnitine supplementation has been linked in some studies to modest reductions in body weight, fat mass, and BMI when combined with exercise/diet. 

What to Know / Limitations & Precautions:

• Evidence is mixed: while some studies show benefits (on fat mass / weight / energy), others show minimal or no effect; L‑Carnitine isn't a magic fat burner. 

• Possible side effects: at high doses or in sensitive people — stomach upset, fish‑like body/urine odor, digestive issues, or mild discomfort. 

• Weight/fat‑loss effects depend heavily on diet, training, calorie balance — supplement alone typically insufficient.

• If you have kidney issues, thyroid conditions, or are prone to seizures — some caution advised, especially with high doses. 

Typical Use Instructions (per product listing):

• Usually: 1 capsule (500 mg) up to 2 times/day, with or without meals. 

• For better effect: use alongside proper diet and exercise — ideally cardio or fat‑burning workouts if fat loss is the goal.

• Because it's non‑stimulant — can be taken any time of the day (unlike caffeine, which you may want to avoid late).
