L-Taurine: Taurine is an amino acid found in many types of foods – including meat and fish. Robert describes taurine as a “mysterious nutrient” that plays an active role in providing glucose homeostasis. In other words, it helps your body manage blood glucose levels. Studies show diabetics tend to have lower levels of taurine than non-diabetics. By taking a taurine supplement, you could promote healthy blood sugar levels. As further proof, Robert cites a study where people took taurine or a placebo for 12 weeks and improved insulin resistance, reduced cholesterol, and promoted healthy blood sugar. Taurine is one of the “big four” nutrients Robert recommends taking each day to balance blood sugar (along with manganese, yarrow, and biotin).
