NutraBio – First Response

Hero-Grade Daily Immune Support for Real-World Protection

First Response was originally formulated to help protect frontline professionals—and now it’s available for anyone who wants powerful, everyday immune support. Each scoop delivers clinical-strength doses of Vitamin C, Vitamin D3, Zinc (TRAACS®), Selenium, Copper, and NAC to reinforce your body’s first line of defense against daily stressors and environmental threats.


Key Benefits

  • Comprehensive immune reinforcement* with high-potency vitamins, chelated minerals, and NAC.
  • Antioxidant defense* to neutralize free radicals and support healthy immune function.
  • Respiratory & cellular support* from NAC, a precursor to glutathione.
  • Bioavailable minerals (Albion™/TRAACS® chelates) for superior absorption and gentler digestion.
  • Built for the front lines—now optimized for daily wellness, travel, busy seasons, and high-exposure environments.

Ingredient Breakdown & Purpose

  • Vitamin C – 3,000 mg (as ascorbic acid): Foundational antioxidant that supports innate and adaptive immunity, collagen formation, and normal inflammatory response.*
  • Vitamin D3 – 50 mcg (2,000 IU): Helps regulate immune cell activity and supports balanced immune signaling—especially useful when sun exposure is limited.*
  • Zinc – 30 mg (as Albion™ zinc bisglycinate chelate TRAACS®): Critical for immune cell development and function; chelated for high bioavailability and reduced GI upset.*
  • Selenium – 200 mcg (as Albion™ selenium glycinate): Essential for antioxidant enzymes (e.g., glutathione peroxidases) that protect cells during immune challenges.*
  • Copper – 3 mg (as Albion™ copper bisglycinate TRAACS®): Complements zinc to maintain mineral balance and supports immune and antioxidant enzyme systems.*
  • N-Acetyl Cysteine (NAC) – 600 mg: A precursor to glutathione, the body’s master antioxidant; supports respiratory health, detox pathways, and cellular resilience.*

Formula Synergy

The high-dose Vitamin C + NAC pairing elevates intracellular glutathione, reinforcing antioxidant capacity during immune stress. Vitamin D3 helps regulate immune signaling, while zinc + selenium + copper (all chelated for absorption) supply critical cofactors for immune and antioxidant enzymes. Together, these actives create a robust, multi-pathway defense system you can rely on daily.

FAQs

When should I take First Response?
Daily, ideally with food. Increase diligence around travel, seasonal shifts, or high-stress periods.

Can I stack it with a multivitamin or zinc?
Yes, but check existing zinc/selenium amounts to avoid unnecessary overlap. When in doubt, ask your healthcare provider.

Is NAC stimulant-free?
Yes. NAC is non-stimulating and supports antioxidant and respiratory health.
