“Drinking milk contributes to increased height growth in humans.”

Growth milk used in this study is rich in nutrients required during bone formation, which enhance height gain. This study found that growth milk supplementation resulted in improved growth parameters... difference in height growth between both group was considered minimal based on child growth standard.

For each additional 8 ounces (236 mL) of milk consumed per day throughout childhood and adolescence, height increased, on average, by 0.39 cm (95% CI: 0.18, 0.60 cm; P < 0.001). The associations are consistent with the literature, which reports associations between milk intakes and height in young children.

In this large cohort of girls, 80% of whom were followed at least 6 years, we found that intakes of dairy milk, yogurt, and dairy protein were positively associated with height growth during the following year; baseline intakes of these were also associated with peak height growth velocity. Baseline milk and dairy protein were similarly associated with eventual adult height.

The present systematic review shows that supplementing the usual diet with dairy products significantly increases bone mineral content during childhood. However, the results regarding a possible relation between dairy product consumption and linear growth are inconclusive. There is a physiological basis for the roles of selected nutrients, especially proteins, calcium, and vitamin D, in growth and development, which are at a maximum during the pediatric period. Milk and dairy products are particularly rich in this group of nutrients.

Controlling for age, sex, BMI-z-score and socioeconomic status, each increment of unsweetened dairy intake was associated with on average 0.04 higher HAZ (equivalent to 0.3-0.4 cm, p < 0.05), and with reduced risk for RSS: OR 0.90, 95%CI: 0.84, 0.97, p < 0.01. No such associations were found with sweetened dairy products. Conclusion: Consumption of unsweetened dairy products (3-4 servings/day) appears to contribute to achieving growth potential in adolescents.

Seventeen trials with 2844 children and adolescents were included. Milk and milk-product interventions resulted in a greater increase in body weight (0.48 kg; 95% CI: 0.19, 0.76 kg; P = 0.001), lean mass (0.21 kg; 95% CI: 0.01, 0.41 kg; P = 0.04), and attenuated gain in percentage body fat (-0.27%; 95% CI: -0.45%, -0.09%; P = 0.003) compared with control groups. However, there were no significant changes in fat mass, height, or waist circumference in the intervention groups compared with the control groups (P ≥ 0.05).

In school-age children and adolescents, dairy intake is linked to increased height and lower risks of obesity/overweight. A 2019 meta-analysis of randomized controlled trials published by Kang et al. assessed whether milk and milk-product consumption can affect growth and body composition in children and adolescents. Their analysis included 17 trials (lasting 3 to 24 months) with a total of 2844 participants, 6 to 18 years of age. The authors concluded that children and adolescents who consume milk and milk products are more likely to achieve a lean body.

Numerous investigations have shown that cow’s milk is a rich dietary source of protein and essential amino acids. Milk consumption is also positively associated with human height and it promotes optimal growth and development of children [10,11]. The investigators concluded that for the average child, each cup of noncow’s milk consumed per day was associated with a height decrease of 0.4 cm.

Daily milk intake improves bone health in kids, especially in the forearms, offering a strategic boost to bone development in young children. Milk supplementation also positively affected bone resorption markers and other bone-related indicators like parathyroid hormone (− 12.70%), insulin-like growth factor 1 (6.69%) and the calcium-to-phosphorus ratio (2.22%).

It estimated a 20% increase in weight and height among children who drank milk, compared with those who didn't.

Milk contains 13 essential nutrients, all of which contribute to healthy bodies. And milk is the No. 1 food source of most of these, including calcium and vitamin D, in the diets of children. Calcium, vitamin D, phosphorus, and protein are necessary for growing strong bones and bodies. Protein is a key nutrient for building muscle at any age.

A growing body of research suggests that regularly drinking milk during the growing years (all the way through late teens to early 20s) is associated with greater height in the teen years, while research has linked regularly skipping milk to reduced height and increased fracture rates.

As best as the current science can answer it, no, milk doesn't make you grow taller, simply because, well, nothing can make you grow taller. But milk can be a useful tool to help kids grow to their potential height. Genetics is a big part of it; most of the variation in height is due to whatever genes you inherited.

A study has found that a country's dietary protein index is one of the strongest predictors of human height, showing the importance of diet.

Milk contains calcium, vitamin D, and protein—nutrients essential for bone development and growth. Additionally, milk contains insulin-like growth factor (IGF-1), which stimulates linear growth. However, the effect size is modest; milk consumption explains only a small portion of height variation, with genetics accounting for approximately 80% of height differences.
