No, unlike other market glutathione products, EDG3 was made to be a precursor – a supplement consisting of nutrients needed by your body to naturally produce the glutathione. Your body utilizes the amino acid as building blocks to generate glutathione the way nature intended. That’s why we can confidently say that it is safe without any side effects. With EDG3, your own body will determine the amount of glutathione to produce, and will not shut down its own synthesis process like the other glutathione products in the market.
