Taurine is known to play a pivotal role in a variety of physiological functions in the body and is believed to have considerable impacts on the cardiovascular system, central nervous system, muscular system and endocrine system in addition to other areas of the body

Physiological functionsCharacteristicsReference No.
Taurine as an antioxidant
  • Neutralizes hypochlorous acid (HOCl)

Baliou et al. (2021), Castelli et al. (2021) 
  • Attenuates endoplasmic reticular (ER) stress

  • Prevents mitochondrial membrane permeability and apoptosis

Taurine in retinal development
  • Exerts neurotrophic effects on the retinal ganglion cells (RGC)

Veeravalli et al. (2020), Chesney et al. (2010) 
  • Enhances chloride influx into postsynaptic neurons

  • Rescue the photoreceptors and ameliorate the visual impairments

Renal actions of taurine
  • Scavenge ROS (reactive oxygen species)

Inam et al. (2018), Han and Chesney (2012), Sun et al. (2016) 
  • Osmoregulatory characteristics have a cytoprotective influence

  • Shows inhibitory effect on the mitogen-activated protein kinase (MAPK) pathways

  • Suppresses the increased in lipid peroxidation and transforming growth factor-β (TGF-β)

Anti-hypertensive action of taurine
  • Sympatholytic action on the central nervous system (CNS)

Han and Chesney (2012), Zhao et al. (2021), Lourenco and Camilo (2002) 
  • Block the activation of the renin-angiotensin-aldosterone system (RAAS)

  • Minimizes the elevation in serum cytokine

  • Reduces oxygen derived free radical generation

Anti-diabetic action of taurine
  • Boosts-up insulin sensitivity and secretion

Han and Chesney (2012), Nakaya et al. (2000) 
  • Reduces mitochondrial calcium overloading

  • Prevents the production of advanced glycation end products (AGEs)

  • Stimulates insulin-independent glucose uptake

Taurine's role in brain development
  • Regulates the hypothalamic-pituitary-adrenal axis

Chung et al. (2012), Ito et al. (2014) 
  • Prevents the impaired calcium handling in sensory neuron

  • Supports the genesis & survival of neurons in the hippocampus

  • Reduces pro-inflammatory cytokines in traumatic brain injury

Cardiovascular actions of taurine
  • Modulates Ca2+ homeostasis

Laidlaw et al. (1990), Zhao et al. (2021), Mousavi et al. (2020) 
  • Reduces the negative effects of norepinephrine

  • Reduces the development of atherosclerotic lesion

  • Prevents oxidant-mediated cardiomyocytes apoptosis

Taurine and aging
  • Maintains the excitation-contraction coupling of muscles

El Idrissi et al. (2013), Yoshimur et al. (2021), Suarez et al. (2016) 
  • Potentiates the rate of sarcoplasmic reticulum (SR) calcium uptake

  • Reduces the age-related reduction in serum insulin-like growth factor-1 (IGF-1), offering beneficial effect as people got older

  • Involves in the inhibition of nuclear factor kappa B (NF-κB)

Taurine and neonatal development
  • Helps infants absorb fat from the gastrointestinal tract

  • Human milk has a better neurodevelopmental outcome

Heird (2004), Chawla (2018) 
Taurine in hair treatment
  • Have a role in the preservation of the human hair bulb

Collin et al. (2006), Kim et al. (2013) 
  • Effective in preventing hair loss caused by stress

Taurine in muscular system
  • Increases skeletal muscle performance

De Luca et al. (2015), Spriet and Whitfield (2015), Kurtz et al. (2021) 
  • Decreases myotonic dystrophy

  • Promotes glucose uptake and lipolysis

  • Reduces mitochondrial apoptosis

  • Decreases age-related sarcopenia
