Perfect product
Javier 21/02/2024
This supplement is one of the best to help our body to fight every day. It gives a highly recommended boost when the body is going through a period of flu or increased physical activity. With a good combination of supplements with the Nac, I avoid taking the typical Paracetamol in several cases, such as cold, flu, etc.

Very suitable
Andres 06/07/2023
It works very well for me, it is a very interesting product. The only thing I would change or improve would be the dosage. It would be much more convenient if it were 600mg

A must-have for the whole year
Anonimus 20/11/2025
One of the best products that exist, the only downside is that it needs to increase the mg doses to 600 mg, since the ones it has right now are very low.

At least positive for me.
Mariano 21/10/2025
It supposedly helps increase glutathione, detoxify the liver, and protect lungs and immune system, at least positive for me personally.
