Heart

Cardiac muscle tissue is among the most mitochondria-dense in the body. The heart cannot afford energy debt - it must sustain continuous output from birth to death. This demand has made it an evolutionary depot for compounds that optimise mitochondrial efficiency.

Bovine heart contains 3-4 times more CoQ10 than skeletal muscle. It is also the richest dietary source of L-carnitine and taurine - both critical for fatty acid transport into mitochondria and electrolyte regulation within cardiomyocytes. These concentrations are not coincidental.

Elastin peptides in cardiac tissue represent an emerging research area. As structural proteins responsible for arterial elasticity, their presence in whole organ tissue - rather than hydrolysed extracts - may offer distinct biological context that isolated peptides cannot replicate.
