The Science & Evidence Behind Every Gummy

Vitamin C enhances immune cell function, supports the production and activity of white blood cells, and acts as a powerful antioxidant protecting cells from oxidative damage. It is essential for children because they cannot synthesise it — it must come from diet or supplementation. Research shows that while vitamin C may not prevent colds, it significantly reduces their duration in children, with particular benefit in children under 6.

Zinc is essential for the development and function of immune cells, including neutrophils and natural killer cells. It plays a critical role in cell division and growth — particularly important for rapidly growing children. Zinc deficiency is common in Australian children and impairs immune response, wound healing, and growth. We use zinc citrate rather than zinc oxide because citrate is significantly better absorbed.

Elderberry has been used for centuries in traditional Western herbal medicine to relieve symptoms of the common cold. Modern research supports this traditional use, with studies showing elderberry extract can reduce both the duration and severity of cold and flu symptoms. The anthocyanins in elderberry have demonstrated antiviral and anti-inflammatory properties. We source ours from Australian-grown elderberry farms.

Vitamin D3 is critical for immune regulation, activating both innate and adaptive immune responses. Despite Australia's sunshine, studies consistently show that a significant proportion of Australian children have insufficient vitamin D levels — particularly during winter and in southern states. D3 is the body's preferred form, and ours is vegan, derived from lichen rather than the conventional lanolin (sheep's wool) source.

Iron deficiency is one of the most common nutritional deficiencies in childhood worldwide, and is directly linked to impaired cognitive development, reduced attention span, behavioural changes, and compromised immune function. These effects can persist even after iron levels are corrected. Most kids' gummy vitamins contain zero iron because it's difficult to formulate — it tastes metallic and can stain teeth. We use ferrous bisglycinate chelate (Ferrochel®), which in clinical trials demonstrated 90.9% bioavailability versus just 26.7% for standard ferrous sulfate. It doesn't cause the constipation, metallic taste, or tooth staining associated with conventional iron supplements.

Calcium is the primary structural mineral in bones and teeth. Children build ~40% of their total bone mass during childhood and adolescence, making adequate calcium intake during these years critical for lifelong bone health. We use Aquamin®, a plant-based calcium derived from mineralised red algae harvested sustainably off the coast of Iceland. Unlike limestone-derived calcium carbonate, Aquamin® contains calcium plus magnesium and 72 trace minerals that work synergistically to support bone mineralisation.

Most kids' vitamins use vitamin K1 (phylloquinone). We use K2 as MK-7 because it has a significantly longer half-life in the body (72 hours vs 1–2 hours for K1) and, critically, it activates osteocalcin — the protein that directs calcium into bone matrix rather than into soft tissues and arteries. This is why K2 is the superior form for bone health: it doesn't just help with blood clotting (which K1 does), it actively builds stronger bones.

DHA makes up ~40% of the polyunsaturated fatty acids in the brain and ~60% in the retina. It is essential for brain development, cognitive function, and visual acuity in children. Because the body cannot efficiently synthesise DHA from plant-based ALA (conversion rate is only 1–5%), direct supplementation is important — especially for children on plant-based or limited-fish diets. We use algal oil because it's the original source of DHA (fish get their DHA from eating algae), with zero mercury risk and no environmental concerns from ocean harvesting.

We use the active, methylated forms of folate and B12 rather than the cheaper synthetic versions (folic acid and cyanocobalamin). This matters because approximately 10–15% of the population carries the MTHFR gene polymorphism, which impairs the conversion of synthetic folic acid to its active form. Methylfolate (5-MTHF) bypasses this entirely, ensuring every child gets usable folate for DNA synthesis, red blood cell formation, and neurodevelopment. Similarly, methylcobalamin is the biologically active form of B12, directly usable by the nervous system.

L-Theanine is an amino acid naturally found in green tea that promotes calm focus without sedation. It works by increasing alpha brain wave activity — the brain state associated with relaxation and attention. Research in children has shown that L-Theanine supplementation improves sleep quality, reduces restlessness, and supports calm behaviour. We use Suntheanine®, the gold standard produced via enzymatic fermentation (not extraction), ensuring pure L-isomer only.

Magnesium glycinate is the most calming form of magnesium — it supports muscle relaxation, nervous system calm, and healthy sleep onset without the GI upset associated with magnesium oxide or citrate. We combine it with chamomile (standardised to apigenin) and passionflower (standardised to vitexin), both TGA-recognised botanicals traditionally used in Western herbal medicine to reduce restless sleep and promote calm. Together, they support the body's natural wind-down process without using melatonin directly.

Most probiotic gummies on the market contain dead bacteria. Standard Lactobacillus strains cannot survive the heat of gummy manufacturing (~70°C) or the acidity of stomach acid. Bacillus coagulans is fundamentally different — it forms protective spores that survive manufacturing, shelf storage, and stomach transit, then activate in the intestine where they're needed. Clinical research in children shows benefits for digestive comfort, immune support, and healthy stool patterns.

Prebiotics feed the beneficial bacteria already living in your child's gut. Inulin (fructo-oligosaccharides from chicory root) is the most well-studied prebiotic fibre, shown to selectively promote the growth of Bifidobacteria in the colon. We pair it with ginger root extract — a TGA-recognised botanical traditionally used in Western herbal medicine to relieve digestive discomfort, nausea, and bloating. Our ginger is Australian-grown from Buderim, Queensland.
