The most common dosages of taurine are 500–2,000 mg per day. However, the upper limit for toxicity is much higher — even doses above 2,000 mg seem to be well tolerated. Research on the safety of taurine suggests that up to 3,000 mg per day for an entire lifetime is still safe ( 53 ).

In addition, taurine supplementation is beneficial to diabetic complications, including retinopathy, nephropathy, neuropathy, atherosclerosis and cardiomyopathy. These useful effects appear due to the multiple actions of taurine on cellular functions.

Animal studies with taurine supplementation have shown increased insulin secretion and action, suggesting that taurine supplementation may have a potential to prevent T2DM.

Administration of taurine attenuated the rise in creatinine and there was less accumulation of gentamicin [70]. In this model, the content of glutathione peroxidase and superoxide dismutase are similar in kidneys of taurine-treated rats and controls.

Accumulating data demonstrate the effectiveness of taurine supplementation against type 1 diabetes, type 2 diabetes mellitus, and metabolic syndrome. Above all, taurine supplementation reduces diabetic complications, including retinopathy, nephropathy, neuropathy, atherosclerosis, and cardiomyopathy.

Taurine reduced blood glucose levels over 12 weeks, and improved OGTT outcomes at 6 weeks after taurine supplementation, in OLETF rats. Taurine significantly reduced insulin resistance but did not improve β-cell function or islet mass.

Taurine supplementation (2%) via drinking water activates antioxidative defense system to alleviate neuropathy associated with diabetes. Taurine reduces serum MDA concentration, suppresses the NF-κB expression, and enhances the Nrf2, HO-1, GLUT1,3 expressions.

Some animal research suggests that an increased intake of taurine could help prevent type 2 diabetes by reducing blood sugar levels and insulin resistance (22, 23). Interestingly, people with diabetes tend to have lower levels of taurine — another indicator that it may play a role in this disease (24).

Also, Taurine is mostly used at night, that’s when the eyes, that’s when every other cell in the body regenerates itself. And so, we recommend if you can take it later in the day, at bed time maybe. Minerals are taken separately, simply because they tend to react with things and form insoluble complexes.

Taurine may help to lower your cholesterol and reduce inflammation in your body. It appears to have no severe side-effects, but more research is needed on the safety of supplementing with taurine.

As a dietary supplement, taurine may help improve athletic performance, support central nervous system function, manage blood sugar levels and maintain heart health. However, taurine may cause side effects or interact with medications. Always consult a doctor before taking taurine or any other supplement.
