Well, liver is a top source for folate, and folate is pivotal for a bunch of other processes including totally natural anti-depressant help (as well as cancer prevention and optimal fertility) - and organ meats are a concentrated source of CoQ10, which is a critical factor for cellular health.
One can purchase expensive supplements or one can master the secret techniques of cooking exquisite organ meats - we fortunately have those options. I like the patheanthropological argument that collagen/bone broth plus organ meats are both part of biodynamic dietary support. For organ meats, capsules are a wonderful help for those of us who’d prefer to avoid having to learn the gourmet tricks of cooking it so its tastes great…
I already use collagen peptides added to undenatured whey in my smoothies at least once a week, and just started taking grassfed, humanely raised liver capsules (2 a day, when I have a smoothie) and noticed distinct energy, like some others have reported.
My next plan is to experiment with cooking grassed/organic liver in the French way that makes it not taste like liver! Apparently marinating it the night before in either red wine vinegar, plain red wine, or milk (not both, just one or the other) does wonders and makes it a delicacy. Not sure how much of the milk carbs would be absorbed by the liver, and red wine or red wine vinegar is prob the lowest carb option. As liver is a major filter of the mammal, I think it’s critical to avoid the industrial factory farm/feedlot beef & chicken liver, as one serving of it may contain many toxins including adrenaline due to inhumane slaughtering practices, which is not helpful for one’s cortisol levels.
Because I have a negative taste memory of liver due to badly cooked liver in childhood, I have postponed eating liver a long time - but when done right, with some butter sauteed slivered onions and garlic, it has been a much loved dish in French cuisine. I imagine with research one can find all sorts of handy liver recipes… I’m just not quite there yet
