- Reviewed in Canada on June 6, 2025Verified PurchaseSmells funny compared to Sisu brand, but it's cheaper so I don't care. Gets the job done.
- Reviewed in Canada on March 21, 2025Verified PurchaseI have found Natural Factors NAC (N-Acetyl-L-Cysteine) to be quite beneficial. Despite noticing several colleagues absent from work, I was able to maintain my productivity, thanks in part to this supplement. However, I would like to highlight a potential side effect: it may influence libido. Therefore, I recommend cycling this product on and off, as is advisable with many supplements. Overall, it offers valuable antioxidant support and aids in restoring glutathione levels, but moderation is key for optimal results.
