Vitamin C is arguably the most important single vitamin for children. It is essential for immune system function — stimulating the production of white blood cells and protecting them from oxidative stress during active infection. It is also an indispensable co-factor in collagen synthesis, which underpins the healthy development of skin, cartilage, bone, and blood vessels. Additionally, Vitamin C significantly enhances the absorption of non-haem iron from plant-based foods — critical for children who eat little or no meat. As a water-soluble vitamin, the body cannot store Vitamin C, making daily replenishment through diet or supplementation essential.

Niacin is central to energy metabolism — the process by which the body converts the food your child eats into usable cellular energy. It also supports the health of the nervous system and plays an important role in DNA repair and skin barrier integrity. For active, growing children who are constantly on the move, Niacin helps ensure their energy systems are running optimally.

Vitamin B6 is involved in over 100 enzymatic reactions in the body, many of which relate to protein metabolism, neurotransmitter synthesis, and immune function. For children, adequate B6 is particularly important for healthy brain development and for the production of serotonin and dopamine — neurotransmitters that directly influence mood, sleep quality, and cognitive function. It also supports the body's ability to produce haem

Folate (the natural form of folic acid) is essential for DNA synthesis and cell division — processes that occur at an extraordinary rate in growing children. It supports the production of new red blood cells, contributes to proper brain and nervous system development, and plays a critical role in tissue repair and growth. Folate deficiency in children is associated with anaemia, poor growth, and neurological complications.

Vitamin B12 is essential for the formation of red blood cells, the health of the nervous system, and the synthesis of DNA. In children, it is particularly critical for healthy brain development and neurological function. B12 deficiency — increasingly common in children with limited animal product intake — can manifest as fatigue, poor concentration, developmental delays, and mood disturbances. Regular supplementation ensures consistent levels regardless of dietary variation.

Biotin is a key player in the metabolism of carbohydrates, fats, and proteins — the three macronutrients that fuel a child's daily activities and growth. It also contributes to the health of the skin and hair, and plays a role in gene regulation. Because biotin is water-soluble and not stored in the body in significant amounts, daily intake is important.

Pantothenic Acid is essential for the synthesis of coenzyme A — a molecule involved in energy production, fatty acid synthesis, and the metabolism of many important biological compounds including hormones and neurotransmitters. It also supports adrenal function and wound healing. For children, adequate Pantothenic Acid helps maintain steady energy levels and supports the body's response to physical and emotional stress.

Zinc is one of the most important minerals for childhood health and is involved in hundreds of enzymatic processes throughout the body. Its roles include supporting immune cell development and function, facilitating wound healing and tissue repair, contributing to normal growth and sexual development, and maintaining the senses of taste and smell — which are directly linked to children's appetite and willingness to eat a varied diet. Zinc deficiency is among the most common micronutrient deficiencies in children globally and is associated with stunted growth, increased susceptibility to infection, and poor appetite.
