L-carnitine has a defined transport role: it physically shuttles long-chain fatty acids across the mitochondrial membrane, where they're actually burned for energy.
L-tyrosine is a different kind of ingredient entirely — it's a precursor to dopamine and noradrenaline, included for mental focus during a calorie deficit rather than for fat loss itself.
Pairing a physical transport molecule with a cognitive-support amino acid is an unusual choice in this category, and it's the last of the six named ingredients in the formula.
Where it sits in the formula: one of six named ingredients on the LipoPeak label, alongside Green Tea Leaf Extract, Cayenne Pepper Fruit Extract, Gymnema Sylvestre.
