Short answer: Vitamin D3 contributes to overall immune wellness, while Magnesium is involved in numerous biological processes, including normal muscle function — two foundational nutrients rounding out the formula's seven-ingredient list.
Why Vitamin D3 specifically connects to respiratory wellness
Immune wellness is broadly relevant to respiratory health, since immune function plays a role in how the body responds to everyday environmental and seasonal challenges.
Why Magnesium's role is described more generally
Magnesium is involved in numerous biological processes — a deliberately broad, honest description rather than an overstated respiratory-specific claim for this particular ingredient.
Why this rounds out a genuinely multi-system formula
Airway support, circulation, antioxidant defense, and now immune and muscle function — the formula spans several connected wellness systems rather than targeting breathing alone.
