Is your head spinning? Do you wake up in the morning with a head full of thoughts and can't turn it off in the evening? Tryptophan is an essential amino acid that the body cannot produce on its own. So we have to get it from food, which is not always easy. And what's so interesting about tryptophan? It is a natural part of the serotonin/melatonin metabolic pathways. Purity and strength in one capsule!

L-Tryptophan doesn't work magic - it works!
In BrainMax L-Tryptophan we used an amino acid that was produced by fermentation . Each capsule contains 430 mg of the active ingredient in a vegetable capsule - without fillers, binders and other ballast substances (E-cells) . Transparency and quality are the absolute standard at BrainMarket , not the exception. We recommend taking it in the evening.
What do we know about this amino acid?
- Did you know that the normal daily intake of tryptophan from the diet ranges between 250 and 425 mg? We managed to squeeze a little more into a single capsule - 430 mg of pure active ingredient!
- Where is it naturally found? It's found in eggs, dairy products, tofu, fish, nuts, and seeds. But let's be honest: getting the right amount through food alone is a real challenge. Tryptophan really does hide well!
- Sleep? No hit parade without tryptophan! Melatonin, the main sleep hormone, is produced by the conversion of serotonin , and serotonin is produced from tryptophan. A simple chain – but one weak link is enough.
- A final tip or the “turkey myth” . You may have heard that after Thanksgiving in America everyone falls asleep because of the tryptophan in turkey. But the truth is a little different: tryptophan is in turkey, but in similar amounts to other types of meat. Fatigue after a big dinner is more likely related to the combination of carbohydrates and overall overeating.

Who is the product intended for?
- Are you working your ass off or studying? We know the tough times very well and we know what's best for our customers.
- Are you looking for a pure dietary supplement without additives? Each capsule contains only this pure amino acid without unnecessary additives.
- Don't want to feel like April Fool's Day weather during the day? Tryptophan plays a crucial role in serotonin production.
- Do you want to finally fall under the covers in the evening and just switch off? Tryptophan is not science fiction or a fairy tale, but a fact that saves you from having to count sheep for a long time.
- Are you a parent who goes 120%? If you're juggling kids, work, and home, you'll appreciate any help that gets you back in the game.
What other products to use with
It's not just about supplying the body with tryptophan – it's also about creating the right conditions for its utilization. In order for tryptophan to be properly converted into serotonin and melatonin, it needs collaborators:
- Better utilization and conversion. At BrainMarket, we firmly believe that high-quality magnesium belongs in every household! In addition, magnesium is a cofactor of enzymes that are involved in the conversion of tryptophan to serotonin.
- Can't get a bit of space for yourself? Relaxing days without feeling pressured? The combination of Ashwagandha and tryptophan won't make unicorns and rainbows appear, but it won't be far off!
- Smooth conversion of serotonin. Vitamin B6 is an important cofactor in the conversion of tryptophan into serotonin. We definitely won't let vitamin B6 go to waste! Choose from a wide range of vitamins in the best form!
