I have a morning shake with a scoop and a half of Optimum Nutrition Protein[1] and 2 tablespoons of Vital Proteins Collagen Peptides[2].
I'm not sure I've noticed any benefits, but like the other commenter mentioned, it keeps me satiated until lunch.
A couple other experiments (among *many):
- Lithium oratate did nothing for me. If anything, it slightly depressed my mood. I don't have depression.
- Supplementing with good quality fish oil and magnesium daily has made pretty noticeable differences.
Currently, this is Sports Research Triple Strength Fish Oil. It has the right mix of whatever oils -- I'd need to go look in my notes to elaborate. Most off the shelf pills (including Kirkland) are inadequate in quality.
For magnesium, I am currently taking Doctor's Best High Absorption Magnesium Glycinate Lysinate.
Advice welcomed from the peanut gallery.
