Taurine

Taurine – Cardiovascular, Neurological & Cellular Hydration Support

An amino acid derivative, taurine contributes to heart and brain health, neurotransmitter balance, and intracellular hydration. Learn how taurine functions in the body and its evidence-based applications in IV therapy.

What the ingredient is

Taurine is a sulfur-containing amino acid derivative found abundantly in heart, brain, retina, and muscle tissues. While the body can synthesise taurine, supplementation may be beneficial under stress, illness, or ageing. It plays critical roles in cellular hydration, cardiovascular function, and neurological regulation.

Mechanism of action

Taurine works by:

  • Modulating ion channels and maintaining electrolyte balance

  • Supporting cell volume and hydration

  • Regulating calcium signalling in muscle and nerve cells

  • Acting as a neuroprotective and cardioprotective agent

  • Participating in antioxidant defence indirectly through mitochondrial support

IV taurine bypasses digestive limitations, delivering rapid systemic availability for acute or therapeutic needs.

Physiological roles

Vitamin B12 is required for:

  • Supports cardiovascular function and healthy heart rhythm
  • Maintains nervous system signalling and neurotransmitter balance
  • Promotes cellular hydration and osmoregulation
  • Protects cells against oxidative stress
  • Contributes to muscle function and recovery
  • Supports metabolic efficiency in energy-demanding tissues

Evidence summary

Studies indicate taurine supports cardiovascular and neurological health, helps maintain electrolyte balance, and contributes to exercise performance and recovery. Clinical and experimental research supports its role in heart rhythm regulation, neuroprotection, and cell hydration.

Potential benefits

Enhances heart and vascular health

Supports brain and nervous system function

Helps maintain cellular hydration and volume

May assist in exercise performance and muscle recovery

Contributes to antioxidant support and metabolic efficiency

Safety profile

  • Taurine is generally well-tolerated, even at high IV doses in clinical studies
  • Possible mild effects: headache, dizziness, or temporary flushing
  • Rare adverse effects; usually safe under medical supervision
  • Caution in patients with renal impairment

Interactions

Taurine may interact with diuretics and electrolyte-altering medications

Synergistic with magnesium, potassium, and B-vitamins for cardiovascular and nerve support

High caffeine or alcohol intake may reduce taurine effectiveness

Evidence rating

Moderate – solid mechanistic and experimental evidence; human clinical trials support cardiovascular and neurological effects, less for long-term anti-ageing claims.
