Smokers require 2–3x more Vitamin C than non-smokers — each cigarette destroys approximately 25mg. When patients quit, the metabolic demand for Vitamin C drops sharply but tissue depletion from years of smoking persists. NRT (nicotine itself) continues to slightly elevate Vitamin C turnover. Restoration of tissue Vitamin C is a months-long process.
Schectman et al. (Am J Clin Nutr, 1989) — smokers have dramatically lower plasma Vitamin C despite adequate dietary intake. Weber et al. — nicotine metabolites are quenched by ascorbic acid, increasing turnover.
Lingering oxidative damage from smoking years, poor wound healing, immune suppression during quit period (which is already an immunological stress)
Vitamin C 1,000–2,000mg daily during and after cessation. Start during NRT phase and continue for 6–12 months. Liposomal form for higher tissue saturation.

Smoking dramatically elevates homocysteine and depletes B6, B12, and folate — the three homocysteine-regulating B vitamins. Bupropion (Zyban) also impairs B6 metabolism via its noradrenergic mechanism. Folate deficiency from smoking-related oxidative stress is associated with lung epithelial damage.
Mansoor et al. (EJCN, 1997) — smokers have significantly elevated homocysteine and reduced B6, B12, folate. Bupropion-induced B6 depletion via noradrenergic mechanism confirmed in antidepressant literature.
Elevated cardiovascular risk (homocysteine), depression during quit attempt, cognitive fog, poor recovery of taste/smell
Methylcobalamin 1,000mcg + P5P 25mg + 5-MTHF 400mcg daily. Full active B-complex formulation preferred.

Cadmium in cigarette smoke competitively inhibits zinc absorption and displaces zinc from metalloenzymes. Zinc deficiency from smoking persists for 6–18 months after cessation as cadmium is cleared from tissues. Taste and smell restoration after quitting is zinc-dependent.
Lyznicki et al. — cadmium in tobacco smoke is a potent zinc antagonist. Zinc restoration is required for taste receptor regeneration. Wound healing deficits in ex-smokers are zinc-responsive.
Delayed taste/smell recovery, impaired wound healing, immune insufficiency, hair thinning
Zinc picolinate 25–30mg daily for 6–12 months post-cessation. Dramatically accelerates taste and smell recovery. Avoid zinc within 2 hours of NRT patches or gum.
