Immune Support Ingredients

Immune support formulas are most commonly built from vitamin C, vitamin D, zinc, and selenium, supported by probiotics and botanical extracts, and Indock sources every one of these categories as branded or unbranded raw materials with full documentation. These ingredients are commonly used to support normal immune function, and we check EU permitted forms and maximum levels before anything ships.

Ingredient categories used for immune support

• Vitamins: vitamin C and vitamin D are the core immune vitamins, commonly used to support normal immune function
• Minerals: zinc and selenium are the minerals most associated with immune support
• Probiotics: live cultures used to support the gut, where much of the immune system sits
• Botanical extracts: elderberry, echinacea, and similar traditional immune botanicals
• Specialty actives: beta-glucans and other actives where a branded, studied form adds differentiation

Branded or unbranded

Most immune ingredients are bought unbranded on spec and price, since the active is the same regardless of supplier. Where you want a specific researched or trademarked form to support a label claim, we source branded ingredients too.

Documentation and compliance

Immune ingredients ship with a certificate of analysis and specifications (see quality and documentation), and we check permitted forms and maximum levels for the EU (see ingredient compliance). When your formula is set, we can also manufacture the finished supplement.
