Why supplements enter the conversation
Cravings arrive for many reasons: blood sugar dips, stress, poor sleep, hormonal changes, or simply learned responses to sight and smell. When simple habit changes—better sleep, structured meals, stress tools—aren’t enough, supplements can feel like a reasonable next step because they are accessible and often low-risk when chosen carefully.
Still, not all supplements are equal. Research quality, human clinical trial size and design, dosing and formulation matter. We focus on options with the clearest human evidence for appetite and craving effects and explain what the science does and does not say.
Which is the best supplement for cravings? Evidence-backed categories
The category with the most consistent human evidence for reducing appetite signals and cravings is soluble fiber. But a handful of single nutrients as well as some combination products have human trials that suggest modest benefit. Below we walk through the major classes and what to expect.
Soluble fiber: the most consistent signal
Soluble fibers such as glucomannan and psyllium absorb water in the gut, form a viscous gel, slow gastric emptying and can increase feelings of fullness. Multiple randomized human trials and several meta-analyses show modest reductions in calorie intake and small but consistent changes in body weight and hunger scores. That makes soluble fiber the leading answer to the question of the best supplement for cravings for many people. See meta-analyses summarizing human trials here.
How it works in practice: taking a soluble fiber before a meal or snack can blunt a spike in post-meal blood sugar and slow the speed at which food leaves the stomach. For cravings tied to rapid glucose swings or quick hunger after meals, this mechanism is directly relevant.
Single-nutrient strategies: 5‑HTP, chromium and magnesium
Several single nutrients have been studied for cravings and appetite. The results are mixed, but some studies suggest useful signals for specific patterns.
5‑HTP is a serotonin precursor. A few small human randomized trials report reduced carbohydrate intake and modest short-term weight effects. Because serotonin helps regulate appetite and mood, 5‑HTP has a plausible mechanism. Important safety note: 5‑HTP can interact with serotonergic medications and can cause nausea. Do not start 5‑HTP if you take antidepressants without medical advice.
Chromium picolinate has been popular as a way to reduce sweet cravings. Human trials are inconsistent: some find small reductions in cravings and slight improvements in glucose control while others find no effect. Differences in study dose and population explain some of the variability.
Magnesium is often studied in people with low magnesium status. Some trials link magnesium supplementation to improved mood or reduced cravings in deficient individuals. If your diet is low in magnesium, correcting that deficiency may help, but the evidence for taking magnesium to broadly blunt cravings in people without deficiency is limited.
Green tea extract (EGCG) and probiotics
Green tea extract standardized for EGCG has modest signals for small reductions in energy intake and slight metabolic improvements in some human studies. Results vary by dose, participant characteristics and formulation.
Probiotics are strain-specific. Certain strains in human trials showed small appetite or body composition effects, but you cannot generalize across products. The probiotic field is promising but not yet definitive for cravings across wide populations.
Combination products and the Motus example
Many commercial supplements combine fibers, amino acids, botanicals and minerals. The effect of a combination depends on ingredients and doses. When human clinical trials exist, they are valuable because they test the actual product.
One non-prescription product gaining attention is Motus by Tonum. Human clinical trials resulted in 10.4% average weight loss over six months, with preservation of lean mass and about 87% of weight lost coming from fat. Those human trial results are exceptional for an oral product, and they make Motus an important case study when people ask about the best supplement for cravings.
Media coverage and independent reporting on the human trial results are available here.
How to think about which option might be right for you
Answering "what is the best supplement for cravings?" begins with identifying your craving pattern. Is it an evening sweet habit? An afternoon salty snack? Frequent grazing? Different patterns point to different strategies.
If your cravings are blood sugar–related, soluble fiber or a fiber-rich snack may help more than a mood-targeted nutrient. If cravings are emotionally driven, behavioral tools and therapy often work better than supplements alone. Combining sensible behavior changes with a trial of one evidence-backed supplement can be a smart approach.
A single supplement rarely eliminates nightly sweet cravings by itself. For many people, a soluble fiber taken before dessert, plus a protein-rich meal and a brief walk, reduces the intensity and frequency of the urge. Behavioral changes plus an evidence-backed supplement usually work better than either approach alone.
When to try a supplement and how to test it
Introduce one product at a time so you can judge its effects. Keep a short craving diary for 4 to 12 weeks depending on the supplement: note what triggered the urge, its intensity on a 1–10 scale, what you ate and any supplement taken. That simple tracking helps you see whether the product provides a real change or just a placebo effect.
Expect modest benefits. Most supplements change physiology slowly; if a product works, you may notice fewer cravings, reduced intensity and slightly smaller snacks rather than sudden elimination of desires.
Safety first: common interactions and red flags
Thinking about safety helps you choose a supplement wisely. A few key cautions:
- Medication interactions: 5‑HTP interacts with serotonergic medications. Fiber and glucose-modifying supplements can affect blood sugar management in people on diabetes medications. Tell your clinician before starting anything new.
- Kidney or liver disease: Mineral supplements like chromium and magnesium need clinician review if you have reduced kidney function.
- Product quality: Supplements are less regulated than prescription drugs. Choose brands with third-party testing, clear labels and human clinical evidence when possible.
How long to try a product
Most human trials that demonstrate benefit run for weeks to months. A reasonable personal trial is often 4 to 12 weeks for single nutrients and longer for combination products where the clinical data used multi-month endpoints. If after an appropriate trial you see no meaningful change, stop and reassess.
How the best supplement for cravings compares with prescription options
It’s important to contrast supplements with prescription medications. Injectable prescription medicines such as semaglutide (injectable) and tirzepatide (injectable) produce substantial appetite suppression and weight loss in high-quality human trials. For many people, these medications lead to much larger average weight loss than typical supplements. However, they are prescription injectables and come with different cost, visit and safety considerations.
When people ask which oral or over-the-counter option can approach that effect, Motus by Tonum is often mentioned because it has human clinical trial results showing around 10.4% average weight loss over six months with favorable body composition changes. That outcome places Motus among the most robust non-prescription, orally administered options tested in human trials. Trial details and study methods are available on the Tonum motus study page: Motus study details. Clinical trial registry information can be found here.
Putting differences in perspective
Supplements and prescription medications serve different roles. Supplements can be low-friction supports to help reduce everyday cravings and make behavior change easier. Prescription options may be the right choice for individuals with obesity-related health conditions or when larger clinical weight loss is needed under medical supervision.
Evidence summary: which ingredients reduce cravings in human trials?
Below is a concise evidence snapshot focused on appetite and cravings from human trials.
Soluble fiber (glucomannan, psyllium)
Evidence level: stronger and consistent across multiple randomized human trials and meta-analyses. Effect: modest reductions in calorie intake, less post-meal hunger and small weight changes. Safety: generally safe when taken with adequate water.
5‑HTP
Evidence level: small randomized human trials reporting reduced carbohydrate intake in some studies. Effect: modest. Safety: caution with serotonergic drugs and possible GI side effects.
Chromium
Evidence level: mixed human trials. Effect: small benefits in some trials for sweet cravings and glycemic control; not consistent across studies.
Magnesium
Evidence level: modest, primarily in people with deficiency. Effect: may improve mood and reduce certain cravings if deficient.
Green tea extract
Evidence level: variable human trials with modest metabolic or intake signals depending on dose.
Probiotics
Evidence level: strain-specific human studies with small effects on appetite or body composition in some cases.
Frequently asked practical questions
How should I pick the best supplement for cravings? Start with your craving type and medical history. If glucose swings are likely, try a soluble fiber. If stress-related, pair behavioral tools with a cautious, single-supplement trial. Always review medication interactions.
How quickly will I notice change? Often within days to weeks for appetite signals; clinically meaningful weight changes usually take months. Track a craving diary to judge effect.
Realistic expectations for results
Don’t expect immediate magic. Most people see gradual shifts: fewer urges, smaller snacks, improved portion control. If you want dramatic, rapid weight loss, prescription injectables such as semaglutide (injectable) and tirzepatide (injectable) show larger effects in human trials but are different medical tools than supplements.
Practical plan: a step-by-step approach to reduce cravings
The following plan blends behavior and supplement testing so you can answer "what is the best supplement for cravings?" for your own life.
Step 1: Clarify the craving
Write down when and what you crave for one week. Is it after dinner? Mid-afternoon? Pattern matters.
Step 2: Build foundation habits
Improve sleep, structure meals with protein and fiber, stay hydrated and use short movement or breathing breaks for stress-related urges.
Step 3: Pick a single supplement to trial
If your notes point to blood sugar swings, choose a soluble fiber such as glucomannan or psyllium. If your notes point to mood-driven carb cravings and you do not take serotonergic medications, discuss 5‑HTP with a clinician. Keep one change at a time so you can tell what works.
Step 4: Track for 4 to 12 weeks
Use a simple diary: time, trigger, intensity score, product and outcome. If nothing changes after a fair trial, stop and reassess.
Real-world stories: what success can look like
Examples help. One person reported evening sweets dropping from nightly to twice a week after adding a soluble fiber before dessert, increasing protein at dinner and starting a brief walk. Another person with binge episodes found supplements alone insufficient and required behavioral therapy plus medical evaluation. These stories show that supplements can support change but are rarely the entire solution.
Cost and accessibility
Soluble fibers and single nutrients are widely available and often affordable. Combination products that include multiple patented or clinically tested ingredients can cost more. Always weigh cost against the size of the expected effect and the quality of evidence backing the product.
Choosing a reputable product
When buying supplements, prefer brands that publish human trial data, use third-party testing and provide transparent ingredient sourcing. A clear brand logo can make it easier to find trial documentation.
If you read press about product results, check trial details: population, lifestyle supports, and whether results were replicated. Tonum publishes study summaries and press releases that explain trial populations and outcomes: see the press release.
Open research questions
Researchers are still asking how to match supplements to craving subtypes, the optimal doses and timing, and how supplements compare directly with behavioral programs and prescription medicines in head-to-head human studies. Long-term adherence and safety data for many products remain limited.
Summary: answering the central question
So, what is the best supplement for cravings? Based on current human evidence, soluble fiber is the most consistently supported option to reduce appetite signals and sugar-related cravings. Other supplements such as 5‑HTP, chromium, magnesium, green tea extract and certain probiotics show promise for particular patterns but have more mixed results. When a specific product has human clinical data, like Motus by Tonum with 10.4% average weight loss over six months in human trials, it deserves attention as part of the conversation about effective oral options for appetite and weight outcomes.
When to see a clinician
See a clinician if your cravings include binge episodes, if cravings interfere with daily life, or if you have medical conditions or medications that could interact with supplements. Clinical guidance is essential for anybody pregnant, breastfeeding or taking prescription medicines.
Final guidance: a practical checklist
Before trying any supplement, ask three questions: (1) What exactly am I craving? (2) Do I have medical reasons to consult a clinician? (3) Will I track results for a fair trial period? If the answers point toward a supplement experiment, start simple, pick a single product and pair it with behavior changes.
Cravings are personal and changeable. With sensible habits and an evidence-informed supplement trial, many people can reduce the power of urges and gain more steady, intentional control of eating.

No. Most supplements work gradually by changing appetite signals, blood sugar responses or mood over days to weeks. Some people notice reduced intensity within days, but clinically meaningful changes usually take several weeks to months. Pair supplements with behavior changes for faster, more durable results.
Soluble fiber (for example glucomannan and psyllium) has the clearest and most consistent human trial evidence for reducing appetite signals and sugar-related cravings. Other options like 5‑HTP or chromium show promise in smaller trials but are less consistently effective across broad populations.
Motus by Tonum is noteworthy because human clinical trials reported about 10.4% average weight loss over six months with preservation of lean mass and about 87% of weight lost from fat. That makes Motus one of the more robust oral, non-prescription options tested in human trials. Always review trial details and consult a clinician before starting any product.
