Daily Nutrition for Peak Athletic Performance

Intense training pushes your body to its limits — and depletes key nutrients faster than diet alone can replace. Thorne’s Foundational Stack for Athletes is a high-performance trio designed to close those gaps, supporting energy, recovery, and resilience so you can train harder, recover faster, and perform at your best.*

  • Multi-Vitamin Elite (AM/PM): A two-part formula tailored for performance. AM capsules fuel daytime energy and metabolism, while PM capsules support nighttime recovery and rest.*
  • D-5,000: Delivers 5,000 IU of vitamin D3 per capsule to strengthen immune defenses and support muscle, bone, and cardiovascular health.*
  • Super EPA: Premium fish oil providing 425 mg EPA and 270 mg DHA per softgel to promote cardiovascular endurance, joint comfort, cognitive function, and a healthy inflammatory response.*

Together, these NSF Certified for Sport® essentials provide the daily nutritional foundation athletes need to stay strong, resilient, and competition-ready.*

When defenses kick in, they burn through nutrients fast. AI1 keeps your system fully charged.
Strengthen Resilience
Antioxidants like curcumin and pomegranate defend against stress that weakens immunity.
Defend Beyond Immunity
