From the Guidelines

Taurine is unlikely to cause palpitations in most individuals, and its potential benefits, particularly in pediatric parenteral nutrition, outweigh the risks of this side effect. The current evidence, including the 2018 guidelines on pediatric parenteral nutrition 1, does not suggest a significant link between taurine supplementation and palpitations. Taurine is an amino acid that plays a crucial role in various bodily functions, including heart health, and its deficiency may lead to more severe health issues, such as cholestasis and retina dysfunction.

Some key points to consider:

  • Taurine supplementation has been shown to maintain plasma taurine concentrations within the reference range in term infants and offer some degree of protection against certain liver diseases in neonatal patients 1.
  • The potential risks associated with taurine supplementation, such as excess intakes, can be mitigated by following recommended guidelines and consulting with a healthcare provider.
  • While taurine may be combined with other ingredients, such as caffeine, in energy drinks and supplements, which can increase the risk of palpitations, taurine itself is not typically associated with this side effect.
  • Lifestyle modifications, such as improved sleep, balanced nutrition, and moderate exercise, can provide energy support without the risk of palpitations associated with certain supplements.

In clinical practice, the benefits of taurine supplementation, particularly in pediatric patients, should be weighed against the potential risks, and patients should be monitored for any adverse effects. However, based on the current evidence, taurine is not likely to cause palpitations in most individuals, and its use can be recommended in certain clinical contexts, such as pediatric parenteral nutrition, under the guidance of a healthcare provider 1.

From the Research

Taurine and Palpitations

  • There is no direct evidence to suggest that taurine causes palpitations. In fact, studies have shown that taurine may have anti-arrhythmic properties and can help regulate cardiac rhythm 2, 3.
  • Taurine has been found to regulate potassium, calcium, and sodium levels in the blood and tissues, which can help prevent arrhythmias and palpitations 2.
  • The study by 2 found that taurine supplementation reduced premature atrial contractions (PACs) by 50% and prevented all premature ventricular contractions (PVCs) in patients with frequent arrhythmias.
  • Another study by 3 found that taurine exhibited diverse biological actions, including protection against ischemia-reperfusion injury, modulation of intracellular calcium concentration, and antioxidant, antiatherogenic, and blood pressure-lowering effects.
  • However, it is essential to note that palpitations can be caused by various factors, and a detailed history, physical examination, and electrocardiogram (ECG) are necessary to diagnose the underlying cause 4.
  • There is no evidence to suggest that taurine supplementation can cause palpitations, but it is crucial to consult with a healthcare professional before taking any supplements, especially if you have a pre-existing medical condition or are taking medications 5, 6.
