Michael Greger: Podcast: What’s Taurine and Why Do We Care? (Part 2)

Key Takeaways

• Consider taurine supplementation (1-3g/day) for modest blood pressure, triglyceride, and blood sugar benefits, especially if prehypertensive or diabetic.
• Monitor for side effects (nausea, dizziness, headaches) if taking >3g/day – stay below this upper safety limit.
• Avoid taurine if you have kidney failure, bleeding disorders, psoriasis, lung cancer, or are pregnant/lactating.
• Vegans/vegetarians may have 15-20% lower taurine levels but deficiency hasn’t been observed – supplementation optional.

Supplements & Protocols Mentioned

• Taurine: 0.5-6g/day (optimal 1-3g/day), taken for 2 weeks to 6 months in studies
• Type 1 diabetes protocol: 500mg taurine 3x/day (1.5g total) for 2 weeks improved artery function
• Prehypertension protocol: 1.6g taurine/day for 12 weeks improved blood pressure and artery function

Notable Quotes

“Taurine has been envisioned as a longevity vitamin…even though we make it, we may also need to get some in our diet to optimize metabolism.”

Bottom Line

Consider trying 1-3g of taurine daily for cardiovascular/metabolic benefits if you don’t have contraindications, but monitor for side effects and stay below 3g/day.
