Product details

Doctor's Best L-Tryptophan provides high-quality nutritional support for individuals seeking to maintain a positive mood and restful sleep cycles. This dietary supplement features TryptoPure, a highly purified, pharmaceutical-grade L-Tryptophan, which serves as an essential amino acid. Because the body cannot synthesize this amino acid naturally, it must be obtained through dietary sources to facilitate the production of serotonin and melatonin.

By supporting these vital neurotransmitters, this formula helps promote a natural sense of calm and relaxation throughout the day and night. Designed to meet strict dietary preferences, these capsules are 100% non-GMO, vegan, gluten-free, and soy-free. This product is an excellent choice for those looking for a clean, science-based approach to wellness.

    Superb for Depression, Excellent for Sleep

    I switched over from the Now Tryptophan powder because it tasted so .... distasteful. This is pharmaceutical grade and is "Tryptopure" and made from entirely plant-based sources. I have double depression and MTHFR, which interferes with the conversion of trytophan into serotonin, so I take a lot of this to get enough serotonin into my system. But it is a life saver. I like it much better than 5-HTP, which does not seem to have much of an effect for me.If I take a lot, it is a great sleep aid (along with Gaba). For this I usually take 4 capsules / 2 grams or 6 capsules/ 3 grams. I wake up feeling refreshed instead of hung over like I would if I took Ambien. At the beginning of the day, I take about 1 gm (2 capsules) to help me feel happy.Make sure to take it on an empty stomach and away from other amino acids like tyrosine. Gaba is a different kind of amino acid, so I take them together. But the trytophan is a relatively weak amino acid and has to compete against other amino acids to get through the blood brain barrier. Sometimes the other amino acids get through the blood brain barrier and this gets swiped away and brought down to the cell walls to be turned into muscle instead of going into the brain to convert into serotonin/melatonin for good mood and good sleep.I also make sure to take it with other vitamins and minerals that help it convert from trytophan into serotonin, like B complex, Vitamin C and magnesium.

    Genuinely helps me sleep

    Menopause has really made it hard to sleep the past few years. The L-tryptophan supplement has greatly improved my quality of sleep. I rarely wake up during the night anymore.

    Magnificent item. No complaints.

    Good product. L-Tryptophan can have different effects on different individuals. This is a good product. It's always a good idea to consult with a competent medical provider when taking new supplements.
