How to increase height after 18?

Gaining height beyond the turbulent years of adolescence has always been a pursuit that captivates the imagination. It’s a time when most of us bid farewell to our vertical ambitions, accepting our stature as a final decree of nature. Yet, hidden in the shadows, there exists a group of individuals who refuse to let age define the limits of their growth. Beyond the age of 18, they cling to the dream of adding precious inches to their frame. While the scientific community may not offer an abundance of data to support these aspirations, there are whispers, stories passed down through generations, of those who claim to have defied the odds. These tales, while anecdotal and not fortified by rigorous statistics, flicker like a distant star in the night sky, offering a glimmer of hope to those who refuse to bow to the status quo. In this exploration, we embark on a journey into the fascinating realm of late-blooming height aspirations, where we will uncover both the possibilities and challenges that accompany this unique pursuit

What are the key determinants of your growth in height?

The process of achieving one’s maximum height is a complex journey influenced by various factors, with the pituitary gland playing a pivotal role in this remarkable odyssey. This tiny yet powerful gland serves as the conductor of a grand symphony of growth hormones, orchestrating the crescendo that determines your ultimate height. This performance typically begins during the transformative years of puberty, generally initiating around the ages of 12 to 13. The crescendo unfolds over approximately six years, though some exceptional individuals may continue to experience additional growth even beyond this allotted period, earning them the distinction of being outliers.

At the core of this height-enhancing spectacle are the growth plates, also referred to as epiphyseal plates, strategically positioned near the ends of our long bones. These plates function as the primary architects of our vertical aspirations as long as they remain active and open. Their ingenious craftsmanship lies in the gradual elongation of these skeletal structures, one inch at a time. However, the final act in this dramatic performance is governed by hormonal shifts that make their debut as puberty draws to a close. These hormonal maestros gradually render the growth plates inflexible and closed, signaling the end of bone lengthening. For girls, this grand finale typically occurs around the age of 16, while boys experience their final bow between the ages of 14 and 19. Thus, the magnificent crescendo of height growth concludes, leaving an enduring mark on our physical stature and the narrative of our lives.


Is it possible for individuals to continue growing in height after reaching the age of 18?

The prevailing wisdom suggests that, for the majority of teenagers, the epiphyseal plates, often referred to as growth plates, typically cease their growth around the age of 18. This widely accepted notion has led many to conclude that our bodies essentially put a halt to the growth process at this stage of life. However, there are situations where growth plates may persist in their activity for further development even after surpassing the age of 18. In such cases, it is highly advisable to seek professional guidance from a medical expert who can assess the status of one’s growth plates.

While it’s true that most adults do not experience significant elongation of their long bones beyond this point, it’s worth noting that daily fluctuations in height are entirely normal. These variations are primarily attributed to the subtle compression of spinal discs. The activities undertaken throughout the day exert an influence on the cartilage and fluid within the spine, leading to minor reductions in height as the day progresses. This temporary reduction in height during daytime activities can add up to as much as half an inch (1.5 cm).

In conclusion, the potential for continued height growth after the age of 18 exists in some cases, albeit rarely. Monitoring and assessment by a medical professional is recommended for those interested in exploring this possibility. Furthermore, it’s important to understand that daily height fluctuations are a natural occurrence in adults due to spinal compression, which can vary throughout the day.

What is the average height at the age of 18?

According to the CDC, the average height at the age of 18 for boys is 6’2” (189.46 cm) and for girls is 5’7” (175.29 cm) (1).

How to make the most out of your limited growth period?

While it may be difficult to make significant changes to your height as an adult, there are measures you can take during your teenage years to maximize your height potential.

Have a fresh and nutritious diet


It is crucial to ensure that you are receiving adequate nutrients and avoiding any deficiencies in vitamins or minerals, especially during your teenage years. While many individuals consume enough food, the quality of their diet often falls short, potentially leading to a lack of essential nutrients necessary for bone health and overall well-being, such as vitamin D and calcium. Calcium plays a role in hormone production that benefits bone health, and vitamin D supports bone health as well.

Increasing your intake of fruits and vegetables can help address malnutrition and promote optimal bone growth. Additionally, consuming an adequate amount of protein is essential for both bone health and muscle recovery. Good sources of protein include eggs, milk, soybeans, and other legumes.

Limit Consumption of Sugary Foods

Consuming sugary foods, especially during adolescence, can lead to obesity and type 2 diabetes, which can cause irregular glucose spikes and disrupt insulin rhythms. Obesity puts additional strain on the joints due to increased pressure from the body. The closure of growth plates also limits the potential for height increase after the age of 18.

Limit Consumption of High-Sodium Snacks

Consuming foods high in sodium can contribute to a nutritional imbalance and increase the risk of serious illnesses, including high blood pressure, heart conditions, and goiter. Excessive salt intake can also lead to the depletion of calcium from the body, negatively impacting both dental health and bone strength.

Stay Hydrated with Water and Consume Milk

Water and milk, in addition to the nutrients obtained from food, play vital roles in promoting height growth. Staying hydrated with water and consuming milk, which is a good source of calcium and other essential nutrients, can support overall bone health and contribute to optimal growth.


Water is a fundamental component of life, aiding in hydration and the transportation of nutrients and oxygen in the body. The recommended daily water intake varies depending on factors such as gender, health, body weight, and height. However, as a general guideline, an average person should aim to consume around 64 ounces of water per day, which is approximately 2 liters, to maintain proper hydration.


Milk plays a crucial role in supporting bone and muscle growth due to its content of calcium, phosphorus, vitamin B12, vitamin D, and protein. Calcium and phosphorus are essential for strong bones, while vitamin B12 and protein support muscle growth and recovery. Consuming milk after a workout can be beneficial for muscle recovery. However, it is recommended to consume no more than 16 ounces (500 ml) of milk per day to maintain a balanced diet.

Getting adequate vitamin D


Dietary changes and lifestyle adjustments alone may not significantly impact height until the body receives adequate amounts of vitamin D. This essential vitamin plays a crucial role in calcium absorption, which in turn supports bone and muscle growth. Insufficient levels of vitamin D have been linked to conditions like obesity and can even contribute to stunted growth in children.

The most direct way to acquire vitamin D is through exposure to sunlight, particularly in the morning. Engaging in 30 minutes of outdoor activity during this time can help children develop stronger and taller bodies. Additionally, vitamin D can be obtained from foods such as dairy products, mushrooms, egg yolks, organ meats, and fortified cereals.


During adolescence, the growth plates in cartilage are more vulnerable and susceptible to damage compared to fully formed bones. Therefore, it is crucial to engage in exercises under adult supervision and with proper techniques. Exercises help strengthen muscles and bones by creating micro-tears that stimulate repair and enhance endurance.

Regular workouts also offer additional benefits, such as improving overall health and reducing the risk of osteoporosis. Osteoporosis is a condition characterized by weakened and fragile bones, which can lead to a loss of bone density and, consequently, a decrease in height over time


Corrected Posture

Maintaining good posture can contribute to an improved appearance of height. By distributing your weight evenly throughout your body, you can help prevent bone and spinal issues. Correcting a hunched posture can visibly impact your height, making you appear taller.


Consistently getting less sleep than the recommended amount during adolescence can have significant consequences. Sleep plays a crucial role because it’s during this time that the body produces growth hormones. Insufficient sleep can lead to decreased production of these hormones and other negative effects. Conversely, getting adequate sleep can enhance growth hormone production. Therefore, it is important for 18-year-olds to prioritize getting 7-9 hours of sleep every night to promote optimal mental and physical well-being.

Maximizing Height with Fish Oil and Height Support Supplements

Ensuring your body receives all the vital nutrients and minerals it needs for optimal growth can be a persistent challenge when relying solely on your daily meals. Fortunately, dietary supplements come to the rescue, specifically tailored to support height enhancement. These supplements not only provide your body with the essential elements required for growth but also contribute to overall well-being, facilitating restful nights of sleep. Height support supplements are available in various convenient forms, ranging from capsules and traditional pills to chewable tablets.

Another valuable avenue to explore is the incorporation of fish oil supplements into your routine. Bursting with protein and crucial fatty acids, fish oil supplements are a natural treasure trove for fostering robust bone growth.

Steer Clear of Detrimental Addictions

The pursuit of height augmentation can be severely hampered by the pernicious influence of addictive substances.

Caffeine: Acknowledge that adequate sleep is a cornerstone of physical growth. Permitting caffeine to disrupt your nightly slumber can lead to a sluggish growth rate.

Nicotine: Beware of the insidious impact of nicotine, which adversely affects both your physical and mental development.

Steroids: While steroids are renowned for promoting muscle growth, their downside lies in inhibiting bone formation. Consequently, individuals who resort to steroids may acquire a bulky appearance but possess a frail skeletal framework, rendering them more susceptible to exercise-related injuries.

In Conclusion

In exceptional instances where growth plates retain their activity, the possibility of continuing to grow taller after the age of 18 exists. However, considering the limited timeframe available for physical development during late adolescence, it becomes imperative to uphold a nourishing diet, engage in regular exercise, and prioritize the attainment of quality sleep. Comparing your current stature to the national average can serve as a valuable benchmark, helping you assess your position and determine whether additional efforts are warranted to achieve a greater height
