Metabolic NutritionTAG, Trans Alanyl Glutamine, 100% L-Glutamine Peptide Powder, Pre Intra Post Workout Supplement, 400 Grams (40 Servings) (Unflavored)

I mix this with protein powder so flavor is not an issue for me. Since taking this product, I have completely put all my digestive issues behind me. I definitely recommend this product. I am a repeat customer and will continue to use this in the future.

I paddle outriggers, both OC1 and OC6. I am usually on the water at least 4 times a week with sessions running from 5 miles to 10 on a regular basis. Most of it is interval training and more intense on the shorter mileage days. Saturdays I may go out 15-20 miles and I need a fast recovery for Sunday's practice especially if practice is going to be a 10 mile run at 70-80%. The faster and more "recovered" I am the more I can apply myself to the next practice and get the most out of it. I have found that once I started taking T.A.G. after a workout I felt less fatigued for the next practice. It is a little on the sweet side so I use 20 oz of water to one scoop verses the 6-10 oz recommended and it works out perfectly for me.If I know I am going to put in some serious mileage I will start my morning off with an egg and half a scoop of T.A.G before hitting the water. Overall I have found myself to recover quicker and better using T.A.G.

This is my 3rd or 4th reorder of this product. It works.

The product is high quality and you will see this from the packaging to the product itself. Not something to be overlooked and missed out on. The company itself is EXTREMELY ethical and backs the quality 100%. Which in this day and age is not always true with supplements.

I found this to be one of the few products that actually does what it says. Not that other products aren’t good, but this one is great. About the sixth day I noticed my recovery after a really taxing work out was much sooner. It’s practically flavorless so I can add it with protein whether it’s a berry flavor or a chocolate or vanilla flavor, it mixes well.

This product used to have a delicious sweet taste, even though it's unflavored. When mixed with water, the taste of the current product is absolutely horrible. One sip was all I could tolerate.I assume I would have to add it to a protein shake with considerable amount of high-carb sweeteners/fruit to make it tolerable, something I would never do for weight-loss reasons. I also doubt that mixing it with artificial sweeteners alone would cover up the revolting taste.Thinking that this had to be a manufacturing fluke, I ordered the same product from another seller, but it was no different.Metabolic Nutrition said the unflavored T.A.G. formula has not changed, just the supplier of the raw ingredients.

I bought this product, but was disappointed that the labeling on amazon does not reflect the actual packaging. After I bought the product I noticed a warning the California's cancer-warning policy...This product contains chemicals known to the state of California to cause cancer/reproductive harm. I don't know what this means for this product, but I am trying you use this product to improve my digestive health, so this labeling is a warning flag for me and I would not have purchased it if I had seen it. I feel especially concerned when a company doesn't show it on their product on amazon and I don't know it until I receive the product in the mail. It feels like there is something to hide. I didn't taste the product, so I gave it a 3 star, since I am not sure how the product is because I returned it.

I am on my second purchase and really love this L-glutamine powder. I use unflavored and add it to my electrolytes - 1 scoop 2x/day. I have maintained muscle mass as I have lost weight and helps me recover nicely from my daily runs & strength training. My only complaint is the packaging is a large container and it is about half full. I am not sure why that is necessary. My hair & skin are also benefited by taking this.
