Before this question can be answered, you have to evaluate the label on the products and check how many carbohydrates are in each serving. Protein and glutamine will not raise your blood sugar and may be OK to be taken before or after exercise, but other additives in the products may increase blood sugar. You should consult with your provider on the best supplements for you based on your total health. It is recommended to do fingersticks (blood glucose readings) before and after exercise, especially if you plan to do resistant training for over 30 minutes. If after exercise your fingersticks are not high (as determined by your provider) and you exercised for 30 minutes or more, you may be able to consume about 15-30g carbohydrates.
