The RDA is the wrong reference and it is worth understanding why.

This answered a question I did not know how to ask.

Clinical perspective, offered as context rather than as advice. The useful move here is to separate what is established from what is widely repeated. Those two sets overlap less than the confident tone of most write-ups suggests, and the second set is where nearly all the disagreement on this board comes from.

The mental-health dimension is under-measured in the trial literature and the reports here are consistent enough to take seriously.

I read this differently from paige_pharma, on substance rather than tone. I would be careful about how confidently the flatness reports get attributed. Rapid weight loss, a large deficit and disrupted sleep produce low mood on their own, and separating that from a drug effect is genuinely hard.

Adding the numbers, since they settle part of this. Keep the original post as written when you update it, and add the correction underneath. An edited-away mistake is invisible to the next person who makes it.

Worth separating that from mood and mental health, which this thread keeps folding into the same question. They behave differently and the advice does not transfer.

Moderator note: reminder that nothing in this thread is medical advice, and that clinical claims need a source. Carry on.
