About This Product
This product, 'L-Glutamine 1000 mg' by NOW Sports, is an amino acid supplement providing L-Glutamine. Each serving delivers 1 gram of L-Glutamine. Research suggests that L-Glutamine is commonly used in doses ranging from 5 to 20 grams per day for certain applications, making the 1-gram dosage in this product underdosed for many common uses. The product has an N+ Score of 29, earning an 'F' grade, indicating a poor overall evaluation primarily due to the underdosed active ingredient. With only one ingredient listed and 100% label transparency, its simplicity is clear, but the low dosage limits its potential efficacy. This supplement may be considered by individuals looking for a very low dose of L-Glutamine or those who plan to significantly increase the serving size.
