Best for

Someone managing stress-related eating or metabolic wellness who wants a stimulant-free supplement with at least some research behind its ingredients, used alongside diet and lifestyle changes.

Skip if

You're looking for a clinically proven weight-loss intervention or a strong appetite suppressant with immediate, noticeable effects — this is a gentle, hormone-adjacent approach, not a dramatic one.

The verdict

CitruSlim stands out from the crowded appetite-suppressant shelf by leaning on two ingredients — Italian bergamot polyphenols and Malaysian Tongkat Ali — that have actual peer-reviewed research behind them, though the evidence for meaningful fat loss specifically is thinner than its cardiovascular and cortisol credentials.

What we love

  • Stimulant-free formula — no caffeine jitters or crash
  • Bergamonte extract is among the more credibly researched citrus polyphenol ingredients
  • Tongkat Ali targets the cortisol-stress-appetite pathway, which many competitors ignore
  • Named active ingredients, not hidden behind a vague proprietary blend label
  • Small, lightweight bottle — easy to travel with

Worth knowing

  • The direct fat-loss evidence is thin — strongest research is on cardiovascular and cortisol markers, not weight specifically
  • No dosage information in the available product details, making it hard to compare against research-backed amounts
  • At $49.95 per bottle, ongoing cost adds up if you're expecting long-term use
  • FDA disclaimer applies — none of the claims have been evaluated as drug efficacy

Our review

What It Actually Is

Let's be honest about the category first: most appetite suppressants are caffeine in an expensive bottle. CitruSlim takes a different angle. It pairs Bergamonte — a full-spectrum polyphenolic extract from Italian bergamot citrus — with Adapticort, NHR Science's branded Tongkat Ali extract wild-harvested from Malaysian rainforest. Neither of these is a stimulant. That's notable.

The Bergamonte Story

Bergamot polyphenols have a more credible research record than most citrus extracts marketed for weight. The Italian bergamot literature is concentrated primarily in cardiovascular health — studies have looked at its effects on LDL, triglycerides, and blood glucose. The connection to weight management is secondary and more speculative: better metabolic markers, fewer energy crashes, a more stable appetite as a downstream effect. NHR Science's claim that it "modulates hunger hormones responsible for satiety" tracks with that general direction, but we'd call it adjacent to the mechanism rather than central to it.

Tongkat Ali and the Cortisol Angle

This is where CitruSlim gets interesting to us. Tongkat Ali (Eurycoma longifolia) has a more robust body of research than its status as a rainforest supplement might suggest — particularly around cortisol modulation and stress-related hormonal dysregulation. For anyone who notices that stress triggers overeating, or who suspects that high cortisol is working against their weight-management goals, addressing that pathway makes more intuitive sense than simply suppressing appetite with stimulants. The "Adapticort" branding signals that NHR Science is emphasizing this cortisol-adaptogenic angle. Wild-harvested sourcing from Malaysia is a quality signal worth noting — the potency of Tongkat Ali varies considerably by source and extraction method.

What It Won't Do

It won't replace a caloric deficit, a sleep habit, or exercise. No supplement does, and we won't pretend otherwise. The FDA disclaimer on the box is the law for all dietary supplements — these claims haven't been evaluated as drug efficacy claims. If you're expecting dramatic, measurable fat loss from a bottle alone, this isn't the product, and honestly, no product is.

The $49.95 Question

For a one-bottle supply, that's mid-tier supplement pricing — more than gas station gummies, less than pharmaceutical-grade single-ingredient compounds. Whether it's worth it depends entirely on what you're actually managing. If you're looking for a stimulant-free approach to stress-eating or trying to support metabolic health alongside other lifestyle work, the ingredient rationale here is more coherent than most. If you just want something to blunt hunger between meals, you may find the effect subtle.

The Bottom Line

We appreciate that NHR Science isn't hiding behind "proprietary blends" with no named actives, and that both headline ingredients have some research pedigree. The honest caveat: the research is more convincing on cardiovascular and cortisol metrics than it is on weight loss. Use it as a support tool, not a solution.

Common questions

1 Bottle CitruSlim® - Appetite Suppressant, answered

Is CitruSlim a stimulant? Does it contain caffeine?

Based on the described formula — bergamot polyphenols and Tongkat Ali — CitruSlim does not appear to contain stimulants or caffeine. It works through hormonal and metabolic pathways rather than stimulant-driven appetite suppression. Always verify the full ingredient label before purchasing if stimulant sensitivity is a concern.

What is Bergamonte extract and does it help with weight loss?

Bergamonte is a full-spectrum polyphenolic extract from Italian bergamot citrus. Its most studied benefits are cardiovascular — supporting healthy lipid profiles and blood glucose. The connection to weight management is real but indirect: better metabolic function and blood sugar stability can reduce appetite and energy crashes. It's not a direct fat-burner.

What does Tongkat Ali (Adapticort) do in this formula?

Tongkat Ali is a Southeast Asian adaptogenic herb studied for its ability to modulate cortisol — the stress hormone that, when chronically elevated, is associated with increased appetite, abdominal fat storage, and metabolic dysfunction. In CitruSlim, it's positioned as the stress-cortisol support component alongside the bergamot.

How long does it take to see results from CitruSlim?

NHR Science doesn't publish a specific timeline, and adaptogenic supplements typically take 4–8 weeks of consistent use before effects are noticeable. Hormonal and metabolic changes are gradual — don't expect week-one dramatic results.

Is CitruSlim safe? Are there known side effects?

Both bergamot extract and Tongkat Ali have established safety profiles in research contexts. That said, this product hasn't been evaluated by the FDA as a drug. As with any supplement, consult your doctor before starting — particularly if you take medications for cholesterol, blood pressure, or hormonal conditions, since bergamot polyphenols may interact.

How does CitruSlim compare to other appetite suppressants?

Most appetite suppressants rely on caffeine or glucomannan fiber. CitruSlim is different: no stimulants, and a focus on hormonal modulation (hunger hormones + cortisol) rather than physical stomach-filling or nervous-system stimulation. That makes it a genuinely different product category — less about blunting immediate hunger, more about addressing the hormonal conditions that drive overeating.
