Nutricost L-Tryptophan 500Mg, 120 Capsules

Good product with good price

Following the recommended dosage on the container, I have found this product to be helpful in establishing a good sleep. I can tells difference in my sleep between nights I take the supplement versus not taking it. I recommend that one consult their primary physician before starting this product or any supplement.

夕食後のグルタミン、VBで寝つけない事が増えたのでトリプトファンをとっています。 よく眠れます。

Value is good. Easy to swallow. Take 2 per night to boost serotonin levels. This is essential for brain function. Safe for everyone. Low serotonin levels are due to lack of gut flora or friendly bacteria. Boost your probiotics and eat non sugary yoghurt, Greek yoghurt, and probiotic pills to repopulate gut bacteria. You need healthy gut flora so you can digest your food, not get heartburn or yeast overgrowth. Gut bacteria produces 80% of serotonin in your body. When serotonin levels are low, you will crave sugar and starch, which will make you fat and give you high blood sugar levels. This in turn will not only give you a fat belly but metabolic disease which means heart disease, diabetes, cancers, etc. Keep blood sugar levels LOW!!! Your body extracts serotonin from chocolate, sugar, starches, but also protein. Boosting with L-Tryptophan will directly replace the serotonin which you need, and reduce cravings for sugars and starches. Make sure you get enough protein too - from meat, eggs, tofu, and different sources. Do not take 5-HTP! Your body will make that from L-Tryptophan directly. And no, there is not enough L-Tryptophan in turkey or ham or spinach to fill your body's need even if you eat a mountain of those foods. Take the supplements for good brain health! Lack of this can lead to depression and other deficiencies. This is a good and safe product. All those folks who say they get all their nutrition from food don't know what they are talking about - especially doctors who have zero knowledge of nutrition and supplements. I've done a lot of research. This is good stuff. If you are chronically depressed take 2 tablets per dose upto 3 x day. Best at night - just 2 capsules for good restful sleep.

I have a terrible time getting a full night's rest, usually waking up between 4 and 5 hours after going to bed, then relying on getting a late morning nap to get me through the day, which interrupts plans for the day most times. So far I have been impressed with this product to help me get a decent night's sleep. Other types of sleep aids such as melatonin don't work for me and leave me feeling foggy headed after getting up. L Tryptophan doesn't do that. Right now I'm taking one capsule about 1.5 hours before bedtime and my ratio of good night's sleep to bad has improved noticeably. Too early to tell if this is something you develop a tolerance to or not. I hope not because so far it's the most effective OTC product I've used so far.

I decided to try Nutricost L-Tryptophan 500mg capsules as a natural sleep aid and to help improve my mood. After using it for a few weeks, I've noticed some benefits but also a few side effects. Many reviewers found that this L-tryptophan supplement helped them fall asleep faster, sleep more deeply, and wake up feeling more rested. Several people said it worked better for them than prescription sleep medications or melatonin. Quite a few also reported improved mood, reduced anxiety and depression symptoms when taking it regularly. However, the capsules contain black pepper extract (Bioperine), which seems to cause acid reflux, heartburn, and stomach discomfort for a significant number of users. The large capsule size was difficult for some to swallow. A few people had a strong negative reaction with insomnia, disorientation or headaches. And for some, it didn't seem to make any noticeable difference in sleep or mood. In my personal experience, I have found some mild benefits to my sleep and general sense of calm and wellbeing when taking 1-2 capsules in the evening. But I also notice an unpleasant burning sensation in my throat and some digestive discomfort, likely from the black pepper extract. Overall, Nutricost seems to provide a cost-effective L-tryptophan supplement that does work well for some in supporting better sleep and mood. But it won't work for everyone, and the potential side effects from the added Bioperine may not be worth it for those with sensitive digestive systems. I'd recommend starting with a low dose and seeing how your body reacts. Pros: + Helps improve sleep quality for many + Can promote better mood and emotional regulation + Cost-effective compared to some other brands + Vegetarian capsules Cons: - Black pepper extract causes acid reflux and digestive upset for some - Large capsules can be hard to swallow - Doesn't work for everyone - Potential to cause insomnia or headaches in a small number of users
