Strength & Immunity - Vitamin D3

GoPrimal VITAMIN D3 – Immune Support, Hormonal Balance, and Energy Boost

Powerful Daily Support for Athletes and Active Lives

GoPrimal Vitamin D3 is a high-potency, clean formula delivering 4,000 IU of cholecalciferol — the most effective form of vitamin D — to support immune strength, hormone production, mood, bone density and muscular performance.

Ideal for athletes, indoor workers, and those with low sun exposure, this D3 supplement is designed to help you feel better, train harder, and recover stronger.

✅ Why GoPrimal D3 Is Better

• 4,000 IU of Cholecalciferol (D3) – Clinical dose to maintain optimal levels
  
  
• No K2 – Perfect for people already getting K2 from diet or separate supplementation
  
  
• Third-Party Tested – Verified for potency, purity, and absence of banned substances
  
  
• Ultra Clean Formula – No fillers, artificial binders, or unnecessary ingredients
  
  
• Sustainable Impact – Every unit supports plastic recovery via our CleanHub partnership
  
  

☀️ 90% of active adults are deficient in vitamin D — and that directly affects recovery, immunity, and strength.

💪 What It Helps You Achieve

• Stronger Immune System – Supports white blood cell function and reduces sick days
  
  
• Better Hormonal Balance – Essential for testosterone, estrogen and thyroid hormone production
  
  
• Enhanced Bone and Muscle Health – Improves calcium absorption and muscle contraction
  
  
• Improved Mood and Energy – Shown to help reduce fatigue and seasonal depression
  
  
• Athletic Performance – D3 deficiency is linked to lower strength and endurance
