Acetyl L-carnitine (ALCAR) has some scientific evidence supporting its use in eye health, particularly for certain ocular conditions. Several studies have investigated ALCAR as part of combination therapies for age-related macular degeneration (AMD) and other retinal disorders. For example, clinical trials have demonstrated that supplementation with ALCAR, often alongside omega-3 fatty acids and coenzyme Q10, may help stabilize or slow the progression of early-stage AMD by improving mitochondrial function and cellular energy metabolism in retinal cells. Some evidence also suggests that ALCAR can benefit patients with optic neuropathies or glaucoma due to its neuroprotective and antioxidant properties. However, most studies use ALCAR in combination with other nutrients, making it difficult to isolate its effects.

The proposed mechanisms include enhancement of mitochondrial energy production, reduction of oxidative stress, and prevention of apoptosis in retinal ganglion cells. While preliminary results are promising, especially in the context of AMD, the overall quality and quantity of evidence is moderate, and more large-scale, long-term randomized controlled trials are needed to confirm these benefits and clarify optimal dosing. Therefore, while ALCAR is not a standard therapy for ocular diseases, its use for eye health is supported by emerging scientific evidence, rather than by tradition or anecdote.
