If there is a difference which would you suggest i take in order to help raise intracellular glutathione levels as much as i possibly can

N-acetyl cysteine is an N-acylated derivative of cysteine so, no, they are not the same thing. To answer your 2nd question, N-acetyl cysteine will increase your glutathione levels the most. See below…
Cysteine is a precursor to the liver detoxifying and antioxidant amino acid glutathione. This functionality provides an anti-aging effect on the body—even reducing the accumulation of age spots. Another impressive function is the break down of mucus in the respiratory tract which can help in bronchitis, emphysema, and tuberculosis.
N-acetylcysteine is the best form of cysteine supplementation and has been proven more effective at increasing glutathione levels than supplements of glutathione itself, or supplements of just L-cysteine.
