Is that a lot?
Every amount on this label with a position sits within the middle 80% of the products that list the same ingredient; 2 ingredients sit inside a blend, so their amounts cannot be compared.
The NIH database records one serving a day from the label's directions; its % Daily Values are for adults and children 4 or more years of age. The directions as printed are further down this page.
The Tolerable Upper Intake Level is the most of a nutrient per day, from food, water and supplements together, that is likely to pose no risk for almost all adults (Institute of Medicine, 2011). It does not apply under medical supervision. This page compares labels; it is not medical advice.

- Directions
- 2. How many should I take? As with all supplements, each person needs to determine what works best for them. The usage on the bottle indicates that 1 capsule should be taken for each 50 – 70 lbs of body weight. Not everyone will need that much, because this is a powerful herbal blend. For some 1 capsule might be enough to get a very good night’s sleep, even though they weigh 165 lbs. For others, even at that same weight, they may need 3 or 4 capsules to nod off easily. It’s best to start at the lower range and work your way up, as needed, to find out what’s best for you.
- 3. How often should I take Serotonin FX? Take as needed. Usually you don’t need it every night. There is a residual effect. Since it actives your circadian rhythm, it won’t make you tired during the day, but will in fact help you sleep at night over a period of days, even with one dose. To start, take for five nights in a row, then see how it affects you taking every other day or even once per week. Experiment. And remember, you can’t overdose on it!
- Now, that said, we do understand that not everyone has an ideal schedule. The important thing here is get a good full night’s sleep when you can (7-8 hrs). When you just cannot, you can also take Serotonin FX to maximize your deep REM sleep during the time you do have. It will increase the quality of your sleep, when you cannot increase the quantity.
