Taurinë

Taurine is a unique amino acid (technically an amino-sulfonic acid) naturally found in:

• meat,

• fish,

• seafood,

• milk.

Unlike most amino acids, taurine is not used for protein synthesis, but it plays an important role in the function of the heart, muscles, brain, eyes, and nervous system.

---

4. May help control blood sugar ⭐⭐⭐☆☆

There is some evidence that it can:

5. Supports brain function ⭐⭐⭐⭐☆

Taurine helps:

• nervous system function,

• neurotransmitter balance,

• protect neurons from oxidative stress.

There is also scientific interest in its role in brain aging, but more human studies are needed.

6. Eye health ⭐⭐⭐⭐☆

Taurine is highly concentrated in the retina and is important for:

• normal retinal function,

• protecting eye cells.

---

7. May support healthy aging ⭐⭐⭐⭐☆

Recent studies have suggested that taurine levels decrease with age and that supplementation may positively affect some markers of aging in animal models. In humans, the results are still developing, and there is not enough evidence to consider it an "anti-aging" supplement.
