Supplement: L-arginine

Benefits of L-arginine

  • can boost your oxygen intake and reduce “brain fog,” according to the scientists
  • contributes to lowering your blood pressure and widening your blood vessels, research says
  • may protect your brain from oxidative damage and improve your memory, study claims
  • can be effective for increasing slow-wave sleep and reducing wakefulness, according to the survey
  • might help support your immunity by participating in the formation of white blood cells, according to a study.

L-arginine can boost your oxygen intake and reduce “brain fog”

Constant tiredness and sleepiness may occur if you have poor blood circulation. In that case, your limbs and brain don’t get enough oxygen to perform at their best. Though, you might be able to boost your oxygen intake and make yourself more energized by taking L-arginine supplements. Scientists claim that this amino acid may improve your blood flow by widening your vessels. They, in turn, can transport more oxygen and nutrient-rich blood to your cells, making you vigorous and reducing “brain fog.”

L-arginine may protect your brain from oxidative damage and improve your memory

If your ultimate goal in taking supplements is to boost your brain performance, then L-arginine can be helpful to you. Recent studies have shown that taking it can significantly improve your spatial working memory and learning skills. Due to its antioxidant properties, this amino acid protects your brain cells from toxins and free radicals (atoms that damage your cells). Thus, it helps maintain solid connections between them. It means that by taking L-arginine, you may lower your chances of getting cognitive-related diseases.

L-arginine can be effective for increasing slow-wave sleep and reducing wakefulness

Does wakefulness stand on your way to deep restorative sleep? In that case, L-arginine supplements may be beneficial for you! Research shows that additional L-arginine intake may increase your slow-wave sleep duration. So this amino acid could be effective as a supplement if you’re struggling with sleep disorders.

What is L-arginine?

L-arginine is a semi-essential amino acid, which means that your body can lack it under certain circumstances like severe infection or trauma. L-arginine helps produce nitric acid, responsible for body processes like improving blood flow, supplying your brain with additional oxygen, and activating immunity cells. At the same time, it acts as a nitric oxide precursor, relaxing blood vessels and widening them.
