I think it does. I've tried other forms/brands and not gotten the same effect as I do from
Solgar 400-mg capsules. If anyone here does decide to go for them, using this link benefits me, because it's through iHerb (full disclosure, lol).
I take one in the AM, one in the PM, but if I feel a crash coming on, I'll take two to stave it off; and if I'm in the middle of a crash, I'll take three or four to pull myself out of it.
At least for me, it works very well. It's expensive -- like, $1 / capsule -- but still. I'm happy it exists at this dose.
