Nutrients Crucial for Fighting Chronic Fatigue and Brain Fog

15. Acetyl-L-Carnitine (ALCAR): Cellular Energy & Cognitive Conductor

Meet Acetyl-L-Carnitine (ALCAR), an acetylated form of the amino acid L-carnitine that acts like an efficient shuttle service within your cells, transporting fatty acids into the mitochondria to be burned for energy. This process is vital not only for physical energy but is especially crucial for your energy-demanding brain. ALCAR is also believed to support the production of acetylcholine, a neurotransmitter fundamental for learning, memory, and attention. By enhancing cellular energy production and bolstering neurotransmitter function, ALCAR can help combat mental weariness, sharpen focus, and promote clear-headedness.

16. Selenium: The Mitochondrial Defender

Selenium may be a trace mineral, but its impact is anything but minor. This antioxidant powerhouse protects your mitochondria—the tiny engines that fuel every cell—from oxidative stress, keeping energy production running smoothly. It also supports healthy thyroid function, which directly influences metabolism and mental clarity. Low selenium levels have been linked to increased fatigue, brain fog, and even low mood. Found in Brazil nuts, tuna, eggs, and sunflower seeds, selenium helps stabilize energy at the cellular level. Just one or two Brazil nuts a day can meet your needs—proof that sometimes, the smallest allies make the biggest difference.
