Appetite & Craving Control Protocol.
A supportive stack that targets post-meal blood sugar stability, satiety signaling, and stress-driven cravings to make appetite easier to manage. It is adjunctive to balanced nutrition and physical activity, not a treatment or cure for any metabolic or eating-related condition.
The appetite & craving control protocol in brief.
A quick summary. The full stack, with dose and timing for each supplement, is below.
The Appetite & Craving Control Protocol is a beginner stack of 7 supplements aimed at weight management: Chromium, Berberine, L-Glutamine, Inositol, Green Tea Extract, Ashwagandha, and 5-HTP. 3 are core and the rest are optional add-ons, at roughly $35-55/mo. Each supplement below lists its dose, timing, role, and the evidence behind it.
What is in the appetite & craving control 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 |
|---|---|---|---|---|
| Chromium | 200-400 mcg (as chromium picolinate) | With breakfast or your largest carbohydrate meal | Core | Moderate |
| Berberine | 500 mg, two to three times daily (1000-1500 mg total) | With meals, divided across the day | Core | Moderate |
| L-Glutamine | 2-5 g | Between meals or when a craving hits | Optional | Emerging |
| Inositol | 2-4 g (myo-inositol) | Once or twice daily with food | Optional | Emerging |
| Green Tea Extract | 300-500 mg standardized to EGCG (count any caffeine toward your daily limit) | With a morning or midday meal, avoid late in the day if caffeine-sensitive | Core | Moderate |
| Ashwagandha | 300-600 mg standardized root extract | Evening, or split between morning and evening with food | Optional | Moderate |
| 5-HTP | 50-100 mg | Late afternoon or 30 to 60 minutes before the evening meal, start at the low end | Optional | Emerging |
Chromium is a trace mineral that may play a supporting role in insulin signaling and post-meal glucose handling, which some studies tentatively link to reduced carbohydrate cravings. Trial results on appetite and weight are mixed and effect sizes are small, so any benefit should be viewed as modest and supportive.
Berberine activates AMP-activated protein kinase (AMPK) and in trials has improved insulin sensitivity and post-meal glucose handling, which may indirectly help steady appetite. It is supportive only and can inhibit liver and gut drug-metabolizing enzymes (such as CYP3A4) and the P-glycoprotein transporter, so anyone on prescription medication should seek clinician guidance.
L-Glutamine is an amino acid that can serve as a substrate for glucose production, and some practitioners use it to try to take the edge off acute sugar or carbohydrate cravings. Direct human evidence for craving control is very limited and largely anecdotal, so it is positioned as an optional, experimental support tool.
Inositol contributes to second messenger pathways involved in insulin signaling and may support insulin sensitivity, with the clearest data in women who have insulin resistance patterns such as PCOS. Any effect on appetite is indirect and the supporting evidence is still developing, so it is included as supportive rather than essential.
Green Tea Extract supplies catechins (notably EGCG) that may modestly support thermogenesis and fat oxidation, complementing appetite-focused efforts. Effects on body weight are small and inconsistent, and high-dose concentrated extracts should be taken with food because of a rare risk of liver injury.
Ashwagandha is an adaptogen that, in small trials, has been associated with lower perceived stress and cortisol, which may in turn reduce stress-driven or emotional eating in some people. It supports the behavioral side of appetite and is not a metabolic treatment.
5-HTP is a serotonin precursor, and serotonin contributes to satiety signaling, so it may help curb appetite in some individuals, though evidence is limited. SAFETY: 5-HTP is serotonergic and must not be combined with SSRIs, SNRIs, MAOIs, or other serotonergic agents without clinician oversight because of serotonin syndrome risk.
How the pieces combine.
The mechanistic rationale for stacking these together rather than taking them in isolation.
- Chromium and Berberine both target post-meal glucose stability through complementary pathways, so taking each with meals gives the steadiest daily appetite support.
- Ashwagandha addresses the stress and cortisol side of cravings while the glucose-focused supplements address the metabolic side, so pairing them covers both behavioral and physiological triggers.
- Take 5-HTP separately from high-protein meals (large amounts of competing amino acids can blunt its uptake), and keep it away from morning stimulants like Green Tea Extract by using it later in the day.
- SAFETY FIRST: 5-HTP is serotonergic. Do NOT combine it with SSRIs, SNRIs, MAOIs, or other serotonergic agents (including tryptophan and St. Johns Wort) without clinician oversight, because of serotonin syndrome risk. This safety separation takes priority over any synergy.
- If you take Berberine alongside glucose-lowering medication, monitor closely with your clinician since additive blood sugar effects are possible, and space Berberine a couple of hours from other oral medications to limit absorption interference.
