There are plenty of studies online re the benefits of taurine supp-lementation, such as found here:-

Do not assume however that they work in all cases. For example, I had numerous nutritional deficiencies pre-rawpalaeo and supplemented heavily but I just p*ssed them out in myt urine and they didn't help me(of course, I had glandular-related issues which might have prevented absorption or some such)
Yes, I don't assume that. The person I'm asking for does get some seizures. Also, the link you provides states:
Taurine is high in eggs, dairy products, meats and fish proteins.
While many other sites state that taurine is low in cow milk:
Taurine, an amino acid derivative found in meat and other animal foods (except for milk and milk products), appears to shield the heart from harm. It's best known for empowering bile acids to clear cholesterol from the body. It may also fight cellular troublemakers that can damage the heart. Studies in animals suggest that taurine lowers blood pressure as well--yet another heart-healthy property. Although research has produced conflicting results, taurine may also benefit vision disorders, epilepsy
"DEFICIENCY SIGNS: Deficiency in Vitamins A, E, and D increases Taurine excretion; epilepsy (low Taurine, high Glycine), 50% of epileptics may void Taurine supplements in their urine; heart disease; slowed growth, biochemical aging process; mother's milk is rich in Taurine, formulas and cows milk are not and may be causing infant abnormalities.
So I'm not so sure about what it reads. Apparently it works better for you in food form, and I'm thinking it likely may be similar for this person. They eat all raw food. I just discussed it with them now, and looks like they may be willing to try goat or sheep milk.
Goat milk contained nearly 3 times higher concentrations of free amino acids than cow milk, and nearly two thirds the level in human milk. Only goat and breast milk contained naturally high levels of taurine.
What are the benefits of goat milk?
Goat milk has natural bioactive factors such as nucleotides, taurine and polyamine which help to build up the immune system.
They do have some supplemental taurine, I think it is by NOW. I'm wondering if it will work as well as food for them, or even if using a synthetic form might put any burden on the body of a sick person? Also, what the source of supplemental taurine is. Can it be fabricated out of nothing in a laboratory? If so, they will be happy with this, especially as raw goat milk may be difficult to come by regularly, for someone not owning nor living near goats, and sick.
