Q: What's the difference between nac-acetyl cysteine and l-cysteine?

N-acetyl-l-cysteine (NAC or NALC) and L-cysteine are two forms of the amino acid cysteine. While they share some similarities, they also have some notable differences. NAC is a modified form of cysteine with an acetyl group attached to it, making it more stable and better absorbed by the body. It is often used as a dietary supplement and has been shown to have antioxidant properties and support liver function, among other potential health benefits. On the other hand, L-cysteine is the unmodified form of cysteine and is a non-essential amino acid, meaning the body can produce it on its own. It is found in many foods, including poultry, eggs, dairy, and whole grains. L-cysteine is also commonly used as a food additive and is often used as a dough conditioner in baked goods. While both NAC and L-cysteine can provide the body with cysteine, NAC is considered a more stable and bioavailable form of the amino acid. Therefore, it's always best to consult a healthcare professional before taking dietary supplements, including NAC or L-cysteine.

Has b12

Supplement is OK but contains vitamin B 12 at 1000 times the required limit, which probably makes it too much considering other vitamins also contain it as well so I will not be purchasing again.
