Acetyl-L-Carnitine (ALCAR) is a modified form of the amino acid L-carnitine, with an added acetyl group that enhances its ability to cross the blood-brain barrier. This makes it particularly effective for supporting brain function, energy metabolism, and nerve health. Unlike regular L-carnitine, ALCAR is more bioavailable to the brain, making it a popular supplement for cognitive and neurological support.

Gelda may benefit individuals seeking mental sharpness, students, older adults concerned about cognitive decline, and those with nerve-related discomfort. Athletes may also use it for enhanced recovery, and some research explores its role in mood support for certain populations.

For mental focus, take it in the morning or before mentally demanding tasks. If using for energy, splitting the dose (morning and early afternoon) may help sustain benefits without affecting sleep.

Gelda is generally well-tolerated, but high doses may cause mild digestive upset, restlessness, or a "fishy" body odor in some individuals. Starting with a lower dose helps assess tolerance.
