I don't know if it will help you but here 's some info:
What does it do?
Taurine is an amino acid (protein building block), as well as a component of bile acids, which are used to help absorb fats and fat-soluble vitamins.
Taurine also regulates heart beat, maintains cell membrane stability, and helps prevent brain cell overactivity.
Where is it found?
Taurine is found mostly in meat and fish. Except for infants, the human body is able to make taurine from methionine—another amino acid.

I don't think they will work too well.
For you to make melanin (lit. tanning pigment), you need the enzyme tyrosinase and the non-essential amino acid tyrosine. Along with many other enzymes and elements.
Basically ...
As with most metabolic pathways, the first compound in a pathway is converted to the next compound by the action of an enzyme.
For example, in the simple pathway A-->B-->C, the conversion of compound A to B occurs because of the action of Enzyme 1, and the conversion of B to C occurs because of the action of Enzyme 2.
The formation of melanin pigment follows a pathway like this, but the pathway is more complex and not all of the steps are known.

The tyrosinase gene makes the tyrosinase. And tyrosine is already abundant if you have a moderate protein diet, and that protein is converted into tyrosine.
That's why tyrosine is a non-essential amino acid: the body makes it, so it doesn't have to be included in the diet.
Tyrosinase (one of the enzymes) converts the tyrosine to DOPA, then to Dopaquinone. The Dopaquinone then forms black-brown eumelanin or red-yellow pheomelanin, because not all types of melanin are the same.

PANTS said:
Because upon initial inspection the idea has merit - supplementing with pre-cursor AA has in the past been shown to sometimes increase target activity.
But its not that easy.
As mentioned in my last post, in simplest form;
A-->B-->C
Having more A doesn't = more activity. There are many other stages, compounds and enzymes that can limit the goal reaction - which in this case is melanogenesis (melanin creation/synthesis).
+ it is a NON - essential AA, and any bodybuilder with a half respectable diet will get there daily amount.
Not everything included in commercial products have a scientific purpose - all they need is a cheap ingredient that has a minor stake in the actual process that is true enough to let them make claims but not deliver results.
