Unlike market glutathione product, EDG3 is a precursor, which is the nutrients needed by your body, to produce the glutathione. Your body utilise the amino acid in EDG3 to produce glutathione naturally. EDG3 provides the necessary building blocks for the body to generate glutathione the exact way nature intended. That’s why it is safe without any side effects. Your body will determine how much glutathione to produce, and it will not shut down its own synthesis process like other market glutathione product.
