Nutritional deficiencies can prevent children from growing to their optimal height or weight.

"Genetics give you a range of how tall you may be, but nutrition determines where you fall in that range. Ensuring a child is nourished with the proper macro and micronutrients prior to puberty could impact their final adult height."

Nutrition to Help Kids Grow

Developed by Pediatricians, Grow Daily 3+ nutritional shakes help round out a child’s diet with key nutrients—vitamins, minerals, protein, amino acids—needed to maximize height growth.

Collection of Healthy Height products
  • Clinically tested in a randomized, double-blind, placebo-controlled clinical trial
  • 12g Protein Per Serving
  • Only 3 Grams of Added Sugar
  • Only 4 oz per serving
  • Contains 350 mg of arginine per serving; children with stunted growth have low circulating levels or arginine
  • Supplemented with vitamins A, C, D and minerals calcium, iron and zinc — nutrients needed to support growth, but commonly deficient in children’s diets

Grow Daily 3+ Clinical Study

Our research-based shake mix formula includes the right combination of protein, amino acids, vitamins & minerals clinically shown to promote growth. The clinical study was published in the Journal of Pediatrics and showed that children who consumed at least one serving a day grew more than the children receiving the placebo.

Grow Daily Boys 10+ Clinical Study

Our research-based shake mix formula includes the right combination of protein, amino acids, vitamins & minerals clinically shown to promote muscle mass in boys entering their teen years. The clinical study showed that boys who consumed at least one serving a day saw increase in muscle mass more so than the boys receiving the placebo.

Nutrition Clinically Shown to Improve Sleep Patterns

If a child is experiencing trouble sleeping start by looking at the amount of calories he or she is consuming each day. Researchers have found a positive correlation between the amount of time a child slept and his or her caloric and macronutrient intake. More specifically, when researchers were evaluating the results from our clinical study they found participants who were consuming the nutrition in Healthy Height fell asleep faster than those with poor consumption.

This study was a prospective randomized, double-blinded, placebo-controlled study of nutritional supplements in 164 healthy lean, short, prepubertal children with 83 in the supplement group and 81 in the placebo group. From November 2010 to November 2013, we focused on children aged three to nine years referred for specialist growth assessments to the Schneider Children’s Medical Center, Israel. Progress was assessed using anthropometric measurements, sleep questionnaires and three-day food diaries at baseline and after the six-month intervention.

Children in the supplement group who took at least 50% of the recommended dose had shorter sleep latency than those who did not (p=0.046). Children who fell asleep in less than 15 minutes had significantly improved standard deviation scores for weight (0.250.34 versus 0.070.36, p=0.044) and height (0.090.13 versus0.030.13, p=0.057) than those who took longer to fall asleep.

Positive correlations were found between mean sleep duration and caloric and macronutrient intake per kilogram.

The conclusion of this study is that adequate nutritional intake was associated with better sleep patterns and may enhance linear growth*.

**While the relationship of sleep and growth has not yet been proven, good nutrition and sleeping habits are critical during childhood and may improve growth outcomes.

Healthy Heights Can Help Children Experiencing

Short Stature

Short Stature occurs when a child’s height is below the average for his or her age and gender. There are sometimes no apparent cause for this to happen, however, there may be underlying medical conditions related to short stature that will require tests and further investigation by a pediatrician.

Low Appetite

Having little to no appetite is often associated with an acute illness. Continued loss of appetite can be associated with poor weight gain or loss of weight, and may indicate a serious chronic illness.


BMI estimates how much body fat a person has and is based on their height and weight. However, for children, BMI estimates are slightly different compared to adults. A child’s body fat percentage changes at a much different pace as they continue to grow. Children’s BMIs are calculated by percentiles rather than by a standard number. Children with low BMIs are considered to be below the 5th percentile. Consult your pediatrician for more information on how to help them progress into a healthier BMI.


ADHD/ADD is a chronic condition that involves difficulty in maintaining attention, as well as increased hyperactivity and impulsiveness. This condition often begins in childhood and can continue into adulthood and may cause difficulties within school, social, and work environments.

Cystic Fibrosis

Cystic fibrosis is a progressive, genetic disease that causes persistent lung and digestive infections and limits the ability to breathe and eat over time. Symptoms may include difficult coughing due to mucus forming within the lungs, inability to gain weight, and runny, fatty stools.

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a complex developmental condition that involves persistent challenges in social interaction, speech and nonverbal communication, and restricted/repetitive behaviors. The effects of ASD and the severity of symptoms differ from person to person.

Caloric Deficiencies Due to High Activity

Children with high activity levels often expend more calories than children who do not the same level of intense activity. This may cause hyperactive children to burn more calories than they consume, causing them to quickly lose weight at a pace that is not ideal for their development.

Feeding Therapy

Feeding therapy is usually conducted by a trained occupational or speech therapist who can assist in teaching a child how to eat or eat better.

Picky Eating

Picky eating is when a child has difficulty accepting certain foods or prefers to eat the same foods over and over. Picky eating is usually prevalent in toddlers and preschoolers. Picky eating often leads to concerns over whether a child is receiving the proper amount of nutrition.
