            Additionally, it’s crucial to note that individuals who are pregnant, nursing, or have existing health conditions, such as kidney disease, should consult a healthcare provider before starting any L-Carnitine supplement. Monitoring dosage is also vital, as excessive intake can lead to complications and adverse effects in certain individuals.

            As always, it is recommended to opt for high-quality supplements from reputable brands and to pair supplementation with a balanced diet and regular exercise to optimize health benefits without incurring undesired side effects.
