Cysteine is an amino acid that is considered to be semi-essential. NAC (N-Acetylcysteine) is cysteine’s supplement form.
The reason why it is considered semi-essential is that it can be produced by the body using other amino acids called serine and methionine. The only time it becomes essential is when the dietary intake of serine and methionine is low.
Many high-protein foods contain NAC, such as eggs, chicken, cheese, yogurt, turkey, legumes, and sunflower seeds. .
One needs to take adequate amounts of NAC because it replenishes glutathione, the most powerful antioxidant present in your body. It also helps with fertility, brain health, and chronic respiratory conditions.

NAC comes as tiny crystals so capsule form is best when taking it (why I switched to Eternum for my NAC).

Was a little confused by the smell of the supplement (it doesn’t smell great) but after checking online this is normal. Have been taking it for a month and have noticed an improvement in my energy and breathing – am getting better sleep too.
