If you’ve ever woken up after a night out with a pounding head, nausea, or fatigue, you’re not alone. These common hangover symptoms are largely caused by acetaldehyde, a toxic byproduct of alcohol metabolism.
That’s why we included L-cysteine in Morning Revival. Because it works with your body’s natural detox systems to fight back against the real root of hangovers.
What Is L-Cysteine?
L-cysteine is a naturally occurring amino acid found in high-protein foods like chicken, eggs, and legumes. It plays a vital role in producing glutathione, your liver’s most powerful antioxidant.
Glutathione helps neutralize acetaldehyde and reduce oxidative stress—two major drivers of hangover symptoms (Wu, 2021).
Backed by Science
A 2020 double-blind, placebo-controlled study published in Alcohol and Alcoholism tested L-cysteine on social drinkers. The group taking 1200 mg of L-cysteine experienced significantly fewer hangover symptoms—notably less nausea, headache, anxiety, and stress—compared to the placebo group (Kaunisto et al., 2020).
This is why our product includes an optimal dose of L-cysteine, designed to support faster recovery and help you feel like yourself again—so you can get back to what matters most.
While no supplement can completely cancel out the effects of excess alcohol, L-cysteine offers a clinically supported way to make your recovery faster and smoother. When combined with the other powerful ingredients in our blend, along with proper hydration and rest, it’s the ultimate choice for a smoother morning-after.
