Melatonin is a hormone that is naturally produced by the body's pineal gland and is involved in regulating sleep-wake cycles. It is also available as an over-the-counter supplement and is commonly used to promote sleep.
However, there has been some concern that the use of melatonin supplements in children and adolescents may interfere with growth and development. In this article, we will explore the evidence for and against the claim that melatonin stunts growth.
The Claim:
The claim that melatonin can stunt growth is based on the fact that melatonin plays a role in regulating the production of growth hormone, which is essential for bone and muscle growth. In animal studies, high doses of melatonin have been shown to reduce growth hormone levels and inhibit bone growth.
Additionally, some studies have suggested that children and adolescents who take melatonin supplements may have lower levels of insulin-like growth factor 1 (IGF-1), which is a key factor in the body's growth and development.
Based on these findings, some have suggested that the use of melatonin supplements in children and adolescents may interfere with growth and development and should be avoided.
The Evidence:
While some studies have suggested that melatonin may have a negative impact on growth and development, the evidence is not conclusive.
One study published in the Journal of Clinical Endocrinology and Metabolism found that children who took melatonin supplements for up to 5 years did not experience any negative effects on growth. Another study published in the Journal of Pediatrics found that children who took melatonin supplements for up to 3 years did not experience any negative effects on height, weight, or BMI.
Additionally, a review of the available research published in the journal Sleep Medicine Reviews concluded that there is no evidence to support the claim that melatonin stunts growth in children and adolescents.
However, it is important to note that the long-term effects of melatonin use in children and adolescents are not well understood, and more research is needed to fully evaluate the safety and efficacy of melatonin supplements in this population.
It is also important to consider the potential risks and side effects of melatonin supplements, which can include dizziness, headaches, nausea, and daytime drowsiness. Additionally, melatonin can interact with certain medications, including blood thinners and immunosuppressants, so it is important to speak with a healthcare provider before taking melatonin supplements.
Conclusion:
While there has been some concern that the use of melatonin supplements in children and adolescents may interfere with growth and development, the evidence is not conclusive. Some studies have suggested that melatonin may have a negative impact on growth hormone levels and bone growth, but other studies have found no such effects.
It is important to consider the potential risks and side effects of melatonin supplements and to speak with a healthcare provider before taking these supplements, especially in children and adolescents. While the available evidence does not support the claim that melatonin stunts growth, more research is needed to fully evaluate the safety and efficacy of melatonin supplements in this population.
