Most people who want to maximize their height focus on calcium and vitamin D.

While both are important, there are several lesser-known supplements that may influence other factors related to growth: IGF-1 signaling, sleep quality, recovery, bone health, and nutrient absorption.

A quick disclaimer: if your growth plates have already closed, no supplement will magically make you 10 cm taller. However, some supplements may help support the biological processes involved in growth and help younger individuals maximize their genetic potential.

In this issue, we'll break down 6 supplements that rarely get discussed compared to calcium or vitamin D:

  • Lactoferrin

  • Astragalus Root Extract

  • Royal Jelly

  • Colostrum

  • Arginine

  • Glycine

For each supplement we'll cover:

  • How it works

  • What the science says

  • How to take it

  • How much it costs

  • Whether it's actually worth buying

1. Lactoferrin

What is it?

Lactoferrin is a protein naturally found in milk, especially in colostrum.

Over the last few years, researchers have become increasingly interested in lactoferrin because of its potential role in bone development and growth-related signaling pathways.

Why might it help?

  • Supports bone health

  • Improves iron absorption

  • May influence growth-related factors such as IGF-1

  • Supports immune function

Because of these mechanisms, some researchers consider it one of the most underrated nutrients for growing adolescents.

Who is it for?

Potentially most useful for:

  • Ages 10–18

May also be beneficial for:

  • Ages 18–25 for general bone health

Less likely to influence height:

  • After growth plates have closed

How to take it

Typical dosage:

  • 200–500 mg daily

Usually taken:

  • On an empty stomach or between meals

Is it worth buying?

If your goal is to support healthy development during adolescence, lactoferrin is one of the most interesting supplements on this list.

Rating: 9/10

2. Colostrum

What is it?

Colostrum is the first form of milk produced after birth.

It contains:

  • Immune factors

  • Proteins

  • Growth factors

  • Small amounts of IGF-1

Why might it help?

  • Supports recovery

  • Improves gut health

  • May enhance nutrient absorption

  • Supports overall development

Who is it for?

Most useful for:

  • Ages 10–20

Also beneficial for:

  • Athletes of any age

How to take it

  • 5–20 g daily

  • Morning or between meals

Is it worth buying?

One of the more interesting supplements for supporting overall development and recovery.

Rating: 8.5/10

3. Glycine

What is it?

Glycine is an amino acid that most people completely overlook.

In reality, it plays an important role in:

  • Collagen production

  • Recovery

  • Nervous system function

  • Sleep quality

Why might it help?

Most growth-related processes occur during sleep.

Anything that improves deep sleep may help the body better utilize its natural growth hormone production.

Who is it for?

Almost everyone.

Especially:

  • Teenagers

  • Poor sleepers

  • Athletes

How to take it

  • 3–5 g

  • 30–60 minutes before bed

Is it worth buying?

Considering how inexpensive it is, glycine may be one of the highest-value supplements on this list.

Rating: 8/10

4. Arginine

What is it?

Arginine is an amino acid often mentioned in discussions about growth hormone.

Why might it help?

Some studies suggest that high doses of arginine can temporarily increase growth hormone secretion.

However, the real-world effects are often much smaller than people expect.

Who is it for?

  • Teenagers

  • Athletes

  • Individuals with low protein intake

How to take it

  • 3–6 g

  • On an empty stomach or before bed

Is it worth buying?

Potentially useful, but not a top priority.

Rating: 6.5/10

5. Royal Jelly

What is it?

Royal Jelly is the nutrient-rich substance worker bees feed to future queen bees.

Because of its unique role in nature, it has attracted attention as a possible growth-supporting supplement.

Why might it help?

  • Contains bioactive compounds

  • May support appetite and overall well-being

  • Shows some promising findings in animal research

The downside

Human evidence is extremely limited.

Most claims regarding height growth remain highly speculative.

How to take it

Depending on the product:

  • 500–3000 mg daily

Is it worth buying?

Interesting, but the evidence is still weak.

Rating: 5/10

6. Astragalus Root Extract

What is it?

Astragalus is a popular herb used in traditional Chinese medicine.

It's most commonly used for:

  • Immune support

  • Stress resilience

  • General wellness

Why might it help?

To be honest, the evidence connecting astragalus to height growth is very limited.

In theory, it may support recovery and overall health, but direct evidence for increasing height is lacking.

How to take it

  • 500–1500 mg daily

  • With meals

Is it worth buying?

I wouldn't purchase it specifically for height.

Rating: 3/10

Final Ranking

πŸ₯‡ Lactoferrin

The most interesting supplement on this list. It has a logical mechanism and promising research related to bone health and development.

πŸ₯ˆ Colostrum

A strong option for teenagers and athletes, particularly for recovery and overall development.

πŸ₯‰ Glycine

The cheapest and possibly the best value supplement here. Better sleep means better conditions for recovery and growth.

4️⃣ Arginine

Potentially useful, but often overhyped.

5️⃣ Royal Jelly

Interesting theory, weak evidence.

6️⃣ Astragalus

Not something I'd buy specifically for height.

If I Had a Limited Budget

My priorities would be:

  1. Glycine

  2. Lactoferrin

  3. Colostrum

Only after those would I consider the othersAnd remember: no supplement can replace adequate sleep, sufficient protein intake, regular physical activity, and proper nutrition.

Those remain the biggest factors in helping your body reach its growth potential.
