CitruSlim® - Appetite Suppressant

What's actually in it

CitruSlim® leans on two ingredients that aren't just label dressing. Bergamonte — the branded full-spectrum extract from Italian bergamot citrus — has a legitimate research footprint around metabolic markers, particularly cholesterol and blood glucose regulation. It's the same fruit behind Earl Grey's distinctive flavor, and the polyphenols that give it that profile also appear to influence lipid metabolism in ways that generic citrus extracts don't replicate. The second ingredient, Tongkat Ali (sold here under NHR Science's "Adapticort" branding), is a Malaysian rainforest root with a long history as an adaptogen and a growing body of evidence around cortisol modulation and hormonal balance.

That combination — a metabolic-support citrus extract plus an adaptogen that blunts the cortisol spike — is a coherent theory. Chronic stress raises cortisol, which increases appetite and promotes fat storage, especially around the midsection. If you're someone who eats differently under stress than you do on a calm weekend, this formulation is addressing something real.

What it won't do

We want to be straight with you: the FDA has not evaluated these claims, and the word "suppressant" in the product name is doing a lot of heavy lifting. Neither Bergamonte nor Tongkat Ali is a stimulant-based appetite suppressant in the way that, say, prescription phentermine is. What the research does support is more indirect — better metabolic signaling, lower baseline cortisol, and potentially improved insulin sensitivity, which together can reduce cravings, especially the kind that spike in the afternoon. But if you're hoping to simply stop feeling hungry, this isn't that product.

We also don't have access to NHR Science's specific dosages for either ingredient, which matters. Bergamonte studies typically use 500–1000mg; Tongkat Ali research tends to cluster around 200–400mg. Without knowing what's in each capsule, we can't tell you whether you're getting a therapeutic dose or a token amount.

The case for it

What we like about this formulation is the focus. A lot of supplements in this space are proprietary blends of six or eight ingredients, most of them present in amounts too small to do anything. CitruSlim® appears to commit to two ingredients with actual mechanisms rather than spreading itself thin across a kitchen-sink formula. The sourcing specificity — Italian bergamot, wild-harvested Malaysian Tongkat Ali — suggests NHR Science cares about raw material quality, which in the supplement world is genuinely half the battle.

At $49.95, it's priced like a focused, quality-forward supplement rather than a bargain bin stimulant. That's appropriate given the ingredient sourcing, though it also means you're committing real money on the strength of a theory.

The honest bottom line

This is a supplement for people who already eat reasonably well, exercise, and are still fighting stress-driven appetite and a metabolism that doesn't respond the way it used to. It's not a shortcut. The ingredients have a plausible mechanism, the sourcing is credible, and the formulation is more coherent than most. That's genuinely more than we can say for the category average.
