Ingredients explained
Vitamin C (ascorbic acid and zinc ascorbate)
As an antioxidant and cofactor for enzymes, it donates electrons to help neutralise free radicals and supports normal immune cell function and collagen formation.
Caution: High doses may cause digestive discomfort; consider taking with food and divide doses through the day.
Zinc (citrate and ascorbate)
Zinc is a cofactor for numerous enzymes and supports normal development and signalling of immune cells.
Caution: May cause nausea on an empty stomach and can interfere with copper absorption if taken in high amounts for long periods.
Vitamin D3 (cholecalciferol)
Vitamin D3 is converted to its active form, which interacts with vitamin D receptors on immune cells and supports normal immune regulation.
Caution: Avoid combining with high-dose calcium or vitamin D from multiple supplements to prevent excessive intake.
Elderberry fruit extract
Provides anthocyanins that act as antioxidants and may support normal immune defence in the upper respiratory tract.
Caution: May cause digestive upset in some individuals; discontinue if adverse reactions occur.
Echinacea purpurea whole plant extract
Contains phenolic compounds and alkylamides that interact with immune cell receptors and may support normal innate immune activity.
Caution: People with plant allergies in the Asteraceae family may be more sensitive.
How they work together
Vitamin C, zinc and vitamin D3 support core immune functions through antioxidant activity, enzyme cofactor roles and receptor-mediated immune regulation. Elderberry and echinacea add polyphenols and alkylamides that engage innate defences and complement micronutrient support.
Safety and tips
