SIGNS YOUR CHILD MIGHT NEED
extra
Support

Always Inured or Has Broken Bones

Higher lysine, Calcium, D3, and K2 work together to strengthen bones, support collagen formation, and help reduce the risk of little breaks — perfect for active kids hitting growth spurts.

Struggles to Build Muscle

Lysine plays a key role in muscle protein synthesis, while Magnesium and Taurine help muscles recover and perform at their best during sport or physical activity.

Stagnant Growth

If their height or strength is lagging, they could be missing key nutrients. Our higher lysine dose, plus Calcium, Vitamin D3, and Collagen, helps them catch up with confidence.

Always Tired

B Vitamins, Magnesium, and Taurine help turn food into lasting energy, so they can keep up during school, training, and weekend activities.

Weak Immune System

Lactoferrin and Zinc help support healthy immune defences, so they spend more time on the field and less time on the sidelines.

Essentialism

Zero Noise

Zero Compromise

3rd Gen Formula
EZZ L-lysine Growth Capsule
Growth gaps don’t happen in a day, and neither does catching up. When your child’s ready for their next big leap, the right nutrition can help them grow stronger, taller, and healthier with confidence.
01
Building Strong Foundations
Ingredients: Lysine, Calcium, Vitamin D3, and Vitamin K2
Strong bones and healthy growth start with the right building blocks. Lysine helps the body produce collagen, essential for bones, cartilage, and connective tissues. It also plays a key role in muscle protein synthesis, helping the body build and repair muscle tissue. Calcium, Vitamin D3 & K2 work together to lock in bone density and strength.
02
Powering Muscle Synthesis
Ingredients: Magnesium, Taurine, Glutamine, and Glycine
Growth isn’t just about getting taller, it’s about building strength. Magnesium supports muscle function, while Taurine, Glutamine, and Glycine help muscles recover, repair, and perform at their best, especially during sport or active play.
03
Supporting Healthy Growth, Every Day
Ingredients: Lactoferrin, Zinc, and Hydrolysed collagen
Growing bodies need strong defences and a well functioning gut. Lactoferrin and Zinc help maintain healthy immune function and beneficial gut microbiome, while Hydrolysed Collagen supports tissue repair. A healthy gut environment also helps the body absorb and use nutrients more effectively, so nothing slows their progress.
