People on HN crack me up. We're smart enough to know that supplements can be beneficial, and how, but not so smart we don't need a nanny to tell us to be careful?
Less anecdotally, regulatory agencies around the world have repeatedly lowered what they consider safe amounts of B6.
B6 is particularly an issue because there seems to be a general assumption that b vitamins are safe, and that water-soluble vitamins cannot be harmful. Couple that with the tendency of multivitamins and energy drinks to add b-vitamins, and it's very easy to end up overdosing on B6, which it turns out can be harmful despite being a water-soluble b-vitamin.
Thanks for the heads' up, this is completely different than the 250mg mentioned elsewhere (iirc) - i'll let people know.
aside: L-theanine made me jittery, boy. Not a fan.
For me: I need 0.3 mg melatonin almost every day to control my sleep and do a bunch of other things. The onset is between 1 to 3 hours. In practice it means I need to be okay with an early wake-up if it kicks in within 1 hour.
When I feel jittery/trembly I need magnesium as my jitters stop when I take it.
Curious about this! Currently trying to figure out a good 0.3mg melatonin dosing regimine for myself.
