Collection: Immune Defense

From guessing to knowing. This collection brings together bundles designed to support your everyday immune routine—especially during seasonal shifts, travel, or demanding weeks.

What you’ll find (depending on the bundle): vitamin C, vitamin D, zinc, and sometimes selenium or lactoferrin.

What research suggests, in plain language:

• Vitamin C: widely studied in the common cold; overall evidence is more consistent for supporting severity and/or duration than for “stopping you getting sick,” and outcomes depend on context.
• Zinc: results in cold studies appear strongly influenced by form, dose, and timing of use.
• Vitamin D: benefits tend to be more noticeable when baseline status is low—making it a smart long-term foundation.

How to use it: pick a bundle that fits your routine and stay consistent. The most reliable approach is simple: habits + daily nutrition, done well.

Important notes: always follow label directions and do not exceed the recommended daily dose. If you take medication or have a medical condition, seek advice before starting.

Recommended tests that fit this goal:

• Vitamin D (self-test or pharmacy test): a simple way to move from guessing to knowing your status.
• CRP (self-test or pharmacy test): a marker often used as an objective check-in around acute inflammation—useful at specific moments.
