I don't think there is an assigned dose, it's more what works for you. Maybe you should scale back to 50. I take 200 at lunch time and I get a little tired but keep myself moving which has helped. I'm 4'10 and 110 lbs if that helps with dosage.

Its a supplement to "help" with despression, sleep disorders, anxiety, migraines, fibro, etc.

What is 5HTP?

200? Wow. I think i would be on the floor. Lol. I bought a bottle at my local walmart and that was the only "mg" they had. Do u order online? I could probably try Walgreens, maybe? I was taking flexeril that made me feel like crud. I wanted to go w a supplement that wouldnt give me that sluggish feeling. Thank you for the advice.
