10g alanyl-glutamine dipeptides to crush recovery and stay hydrated
Metabolic Nutrition TAG is a no-frills recovery powder that nails one thing: getting glutamine into your system in a smarter, more stable way than plain old free-form stuff. It skips the kitchen-sink approach and puts the full 10g serving into T.A.G. Trans Alanyl Glutamine dipeptides. That's key because alanyl-glutamine isn't just glutamine with a fancy label—it's a dipeptide built for better stability in drinks and easier gut absorption, which is huge for athletes pushing high volume and needing solid recovery and hydration.
The star here is T.A.G. at 10g, a dipeptide mix with trans-alanyl-glutamine and L-alanyl-L-glutamine, like the popular Sustamine® form. It works by using peptide transporters in your gut, like PepT1, to get absorbed fast and then break down into alanine and glutamine. That gives you double benefits. Glutamine helps with nitrogen shuttling, fueling gut cells, supporting immune function, and bouncing back from tough workouts. Alanine aids amino acid metabolism and keeps energy going during long or repeated efforts. In real life, it means less of that wiped-out feeling after sessions, better hydration hold, and more consistent training weeks.
The dose is legit. 10g per serving is at the high end for glutamine recovery in sports supps, matching what's used in studies on exercise recovery and hydration with alanyl-glutamine. This isn't some weak 2-3g add-on for show—it's the real deal.
Key Highlights
- 10,000mg T.A.G. per scoop—this is a full-on recovery hit, not just a dash of glutamine in a mix. The whole serving is alanyl-glutamine dipeptides, so it has real punch for your training.
- Smarter glutamine delivery—TAG goes with alanyl-glutamine over basic free-form. It's more stable in your drink and uses gut peptide transporters for better uptake.
- Solid dose for real results—10g is right up there with what athletes use when they want glutamine to actually help. Way better than those tiny doses just for the label.
- Hydration boost beyond regular aminos—alanyl-glutamine helps with fluid and electrolyte uptake, especially in sweaty or hot workouts. Great if dehydration hits your performance as hard as muscle fatigue.
- Perfect for back-to-back training—lifters, fighters, and conditioning fans don't always need more buzz; they need faster recovery. TAG supports that so you can keep hitting sessions hard.
- No stims at all—no caffeine or energy kicks to deal with. Easy to mix in pre, intra, post, on off days, or evenings without messing up your sleep.
- Keep-it-simple approach—one clear ingredient, one job. In a world of bloated amino blends with weak extras, TAG shines by going all-in on a hefty dose of this recovery dipeptide.
- Straight-up dosing—no prop blends hiding stuff. You see the 10g serving, know what's in it, and can compare it to research without guessing.
Who Is This For?
- Bodybuilders in big volume phases with lots of eccentric work and back-to-back days. 10g alanyl-glutamine dipeptides give targeted recovery and hydration without stims, perfect for evening sessions or off days.
- CrossFit and functional athletes blending lifts, intervals, and sweaty conditioning weekly. TAG works because alanyl-glutamine helps recovery and hydration, key when fatigue builds from volume, not motivation.
- Fighters mixing skills, sparring, running, and strength. They need recovery without sleep or heart rate issues, and this stim-free dipeptide fits weight cuts too.
- Endurance folks in heat or repeated long hauls where hydration equals calories. Alanyl-glutamine smartly supports fluid uptake and keeps you going when sweat amps fatigue.
- Powerlifters in frequent training who want training quality, not hype. TAG focuses on handling heavy work's recovery load across the week.
- Dieting lifters seeing recovery, fullness, and consistency drop with calories. This glutamine dipeptide helps without filler junk.
How to Use
Mix 1 scoop— that's 10g of T.A.G. Trans Alanyl Glutamine—in 12-20 oz of water for a lighter or stronger mix. For hydration, take 15-30 min pre or sip during if it's long, hot, or intense. For recovery, hit it right after or between meals on training days. Stim-free means no tolerance worries—smaller folks can start half-scoop for gut check if new to aminos. Fine with or without food, but lighter feel away from big meals. Stack with creatine monohydrate, electrolytes, carb powders, or protein for strength, hydration, glycogen, or repair focus. No need to cycle; daily use fits ongoing recovery needs. Keep it sealed cool and dry for best mix.
What to Expect
Minutes 0-10: Mix and sip like any amino—no energy rush or wild taste. Minutes 10-40: No caffeine kick; it's about in-session support, especially with water during tough, sweaty workouts. Minutes 40-90: Here's the win—sessions feel less draining, and recovery post-workout is smoother, not a total drop. Days 1-7: Notice less beat-up vibes after multiple sessions, especially in heat or high volume. Weeks 2-4: The real gain is consistency—better flow between trainings, less fatigue buildup, and reliable readiness all week.

Frequently Asked Questions
What is Metabolic Nutrition TAG actually made of?
TAG is built around a 10g serving of trans alanyl glutamine / alanyl-glutamine dipeptides. Available formula verification points to a TAG Dipeptide Matrix containing trans-alanyl-glutamine and L-alanyl-L-glutamine, including the alanyl-glutamine form commonly associated with Sustamine®.
Why use alanyl-glutamine instead of regular L-glutamine?
Alanyl-glutamine is a dipeptide form designed for improved stability and efficient uptake through peptide transport pathways in the gut. In practical terms, it is a more advanced delivery format for athletes who want glutamine support tied to hydration and recovery rather than just a generic glutamine powder.
Is 10g of TAG a serious dose?
Yes. A full 10g serving is a substantial stand-alone dose for a glutamine-related recovery product and clearly above the token amounts often used in mixed amino formulas. This is one of the strongest reasons the formula has real credibility.
When should I take TAG for best results?
Use it pre- or intra-workout if your priority is hydration support during long, hard, or sweat-heavy training. Use it post-workout if your main goal is improving recovery turnover after lifting or conditioning.
Will I feel TAG right away like a pre-workout?
No. TAG is not a stimulant product and does not produce a caffeine-style rush, tingles, or immediate mood change. The payoff is subtler: better hydration support around training and better recovery quality across repeated sessions.
Can I stack TAG with creatine and protein?
Absolutely. TAG stacks very well with creatine monohydrate for strength and power support, and with whey isolate or a whole-food protein source for post-workout muscle repair. The formula is narrow enough that it complements, rather than duplicates, those products.
Is this product better for intra-workout or post-workout use?
Both are valid, but the best choice depends on your bottleneck. If you train long, sweat hard, or perform in heat, intra-workout use is especially logical because alanyl-glutamine supports fluid handling; if your main issue is soreness and recovery between sessions, post-workout use is a strong fit.
Does TAG need to be cycled?
No. There are no stimulants here and no tolerance-driven reason to cycle it. Consistent daily use generally makes more sense if your recovery demand is ongoing.
Is TAG only for bodybuilders?
No. Bodybuilders benefit from the recovery support, but endurance athletes, CrossFit athletes, fighters, and anyone training in hot or high-output conditions can also benefit because alanyl-glutamine supports hydration and recovery together.
Does TAG contain caffeine or stimulants?
No. TAG is a stim-free recovery powder. That makes it suitable for evening use, rest days, and for athletes who already get enough stimulation from coffee or pre-workouts.
