L-Arginine: A Key Building Block for Growth

L-Arginine is one of the 9 essential amino acids that serve as the building blocks of protein. In children, arginine plays a significant role in growth and development.

L-Arginine and Growth in Children 

Arginine is an amino acid that is important for growth and development in children through its role in promoting the release of growth hormone. Protein can also influence growth less directly, with arginine and leucine influencing calcium absorption and the gut microbiome - which are essential for supporting healthy growth.

In children who are experiencing growth delays, blood levels of arginine are usually found to be very low. However, supplementation of arginine alone does not necessarily address the stunting since an overall balanced and nutrient-rich diet is needed to promote growth.

Why L-Arginine in Grow Daily 3+?

Most of the L-Arginine content in Grow Daily 3+ is actually naturally present in whey protein. However, with their vast research into nutrition and growth, the Healthy Heights medical team identified the need to incorporate the free amino acid form of l-arginine into the formula to make the supplementation more impactful.

This level of supplemental arginine was set based on research and review of clinical data in children - ensuring the 50mg added was appropriate for children ages 3-9. As a result, parents can feel good about offering Grow Daily 3+ to their children knowing the product is designed and researched by doctors.
