FAQ
FAQ
The Immune Stack is a three-product daily support system built around Klean Probiotic, KLEAN-D™ Vitamin D3, and Klean Zinc. Together, they are designed to support gut health, normal immune function, bone and muscle function, and everyday resilience. It is especially practical for active adults and athletes who want a simple, consistent way to support foundational health during hard training, travel, and busy schedules.
The stack includes Klean Probiotic, KLEAN-D™ Vitamin D3, and Klean Zinc. Klean Probiotic provides 15 billion CFU plus prebiotics to support gut health. KLEAN-D™ provides 5,000 IU of vitamin D3 to support immune, bone, and muscle function. Klean Zinc provides 10 mg of elemental zinc to support normal immune defense and cellular health.
Your digestive system and immune system are closely connected, which is why gut support matters. Klean Probiotic provides 15 billion CFU from multiple probiotic strains along with prebiotics and acid-resistant capsules. The goal is to support a healthy gut environment as part of a broader daily wellness routine—not to treat or prevent illness.
Vitamin D plays an important role in normal immune function, bone health, and muscle function. KLEAN-D™ provides 5,000 IU of vitamin D3 per serving, which may be especially relevant for people who train indoors, get limited sun exposure, or have been advised to pay closer attention to vitamin D intake. Because individual vitamin D needs vary, customers with medical conditions or concerns about vitamin D status should speak with a qualified healthcare professional.
Zinc is an essential mineral involved in normal immune function and cellular health. Klean Zinc provides 10 mg of elemental zinc per serving. The goal is not to take excessive amounts, but to provide a measured daily dose as part of a complete routine. If you already take another multivitamin or zinc-containing supplement, check your total daily intake before stacking products.
No supplement can guarantee that you will not get sick, and the Immune Stack is not intended to diagnose, treat, cure, or prevent disease. Its purpose is to support normal immune function, gut health, and nutrient status so your daily routine has a stronger foundation. Sleep, adequate calories, protein, hydration, stress management, and recovery still matter.
Yes, that is one of the situations where the stack may make sense. Hard training, travel, changing schedules, limited food variety, and inconsistent routines can make it harder to stay on top of basic health habits. The Immune Stack gives athletes a simple way to support gut health, vitamin D intake, and zinc intake while they continue focusing on proper nutrition, hydration, sleep, and recovery.
Yes. The Immune Stack is built around Klean Athlete products that are positioned as NSF Certified for Sport®. This is especially important for competitive and drug-tested athletes because NSF Certified for Sport® testing provides added assurance regarding banned substances and label accuracy. Athletes should still follow the supplement policies of their school, team, league, or governing organization.
Often yes, but review your full supplement routine first. If you already take a multivitamin, vitamin D, zinc, or another probiotic, you may be doubling up on nutrients unnecessarily. More is not automatically better. Follow the label directions and speak with a healthcare professional if you take medications, have a medical condition, or are unsure whether the stack fits with your current supplement plan.
