Smoking Cessation Support Protocol.
Adjunctive support for adults actively quitting tobacco, aimed at glutamate balance, cravings, and replenishing antioxidant status. It should sit alongside evidence-based cessation counseling and clinician care and is not a replacement for approved cessation treatment.
The smoking cessation support protocol in brief.
A quick summary. The full stack, with dose and timing for each supplement, is below.
The Smoking Cessation Support Protocol is an intermediate stack of 3 supplements aimed at respiratory health: NAC, Fish Oil, and Vitamin C. 2 are core and the rest are optional add-ons, at roughly $20-40/mo. Each supplement below lists its dose, timing, role, and the evidence behind it.
What is in the smoking cessation support protocol.
Dose, timing, role, and evidence tier for each supplement. Core items carry the protocol; optional ones are situational. Open any name for the full profile.
| Supplement | Dose | Timing | Role | Evidence |
|---|---|---|---|---|
| NAC | 600 mg twice daily | With meals | Core | Emerging |
| Fish Oil | 1-2 g combined EPA and DHA | With a meal | Optional | Emerging |
| Vitamin C | 250-500 mg | With food | Core | Moderate |
NAC has been studied as an adjunct for smoking cessation through glutamate and oxidative stress pathways, with mixed but plausible early evidence. It is supportive and should not replace a structured quit plan.
Omega-3 intake has pilot evidence for reducing tobacco craving and may support inflammation balance during quitting. It is an adjunctive craving-support tool, not a cessation medication.
Smoking depletes ascorbate, and moderate supplementation can help restore vitamin C status in smokers. This supports antioxidant repletion but does not directly cause cessation.
How the pieces combine.
The mechanistic rationale for stacking these together rather than taking them in isolation.
- NAC and Fish Oil may help the craving and irritability side of quitting, while Vitamin C addresses a common nutrient depletion pattern in smokers.
- Set a quit date and use counseling or clinician-supported cessation care as the main intervention; supplements are only support.
- Track cravings, sleep, and relapse triggers weekly so the stack is judged against behavior, not just how it feels.
