I've been looking at a product called 'moon brew' they listed this supplement for one to stop you mind from racing at night. Dosage says 1. I found that the first few weeks of taking this vitamin, that it did slow my racing thoughts and I've been able to get back to sleep. But, I feel I have hit a plateau and have increased the dose to 2 and it has silenced my mind! With said increase, I'm sleeping better and I've also noticed a case of vertigo. This could be hormonal based but the correlation between the time I increased it and the dizziness, I can't help but feel this vitamin is causing it. Something to pay attention to.

Great for mood enhancement. Better than coffee to help me start the day on the right foot.

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.
