>Vitamin D3

Irrelevant amounts come from diet, adequate amounts come from sun exposure. Everyone should be supplementing this.

>Taurine, creatine, Carnosine

Irrelevant, synthesized by the human body.

>Retinol

Best consumed from carrots, sweet potatoes, etc. Only relevant animal source is organ meat (liver), which most people aren't consuming.

>B12

Even meat lovers get deficient on this, dietary intakes are usually inadequate. My mother and sister are rabid meat eaters and supplement it, everyone who has the means to should.
