Nutri-West DSF (De-Stress Formula) is a physician-grade adrenal and stress support formula — one of Nutri-West's most foundational and widely prescribed clinical formulas, used by integrative practitioners for over four decades for patients with adrenal fatigue, HPA axis dysregulation, chronic stress, and cortisol imbalance. 120 capsules.DSF Formula provides comprehensive HPA axis and adrenal support through multiple nutritional and botanical mechanisms: Vitamin C (the adrenal cortex concentrates more Vitamin C than any other body tissue, and it is rapidly depleted under stress); Pantothenic Acid (Vitamin B5 — the essential cofactor for adrenal corticosteroid synthesis); B-complex vitamins in their active, coenzyme forms for nervous system energy support under stress; Adaptogenic herbs (Ashwagandha, Rhodiola, or Eleuthero) for cortisol normalization and HPA axis resilience; Adrenal Glandular (bovine adrenal tissue extract — a glandular therapy approach to supporting adrenal function with organ-specific peptides and cofactors). Nutri-West is a physician-only professional supplement company founded in 1983, formulating targeted clinical nutrition products exclusively for healthcare practitioners using pharmaceutical-grade ingredients.
