CitrusBurn targets thermogenesis with 7 botanical ingredients anchored by Seville orange peel extract (p-synephrine). The ingredient profile is backed by peer-reviewed research, and the 180-day money-back guarantee is among the strongest we've seen. If you're over 35 and feel like your metabolism has been working against you, this formula was specifically designed for that problem.
Visit Official CitrusBurn WebsiteCitrusBurn was born out of an unusual discovery. Clinical nutritionist Dr. Michael Reeves was researching the dietary habits of residents in Carmona, a small village in southern Spain where locals reportedly maintain healthy body weight well into their 80s and 90s — despite eating bread, fatty meats, and pastries daily. The common thread? A bitter variety of Seville orange that's central to their diet.
That research led to CitrusBurn: a proprietary blend of 7 botanical ingredients built around p-synephrine, a natural compound found in Seville orange peels. The formula is manufactured in an FDA-registered, GMP-certified facility in the USA and is designed to support the body's natural ability to burn calories efficiently — especially for adults over 35 who feel like their metabolism has stopped cooperating no matter what they try.
The core idea behind CitrusBurn is straightforward: as we age — particularly after 35 — our body becomes less efficient at thermogenesis, the metabolic process that burns calories for heat and energy. Instead of converting food into fuel, our body starts storing more of it as fat. The manufacturer calls this decline "thermogenic resistance." It's their own term, not a formal diagnosis, but the underlying science — that metabolism slows significantly with age — is well-documented.
The star of the formula is p-synephrine, a natural alkaloid found in high concentrations in Seville orange peels. It's structurally similar to ephedrine (the once-popular fat burner that was pulled from the market), but without the dangerous cardiovascular side effects. A comprehensive review in the International Journal of Medical Sciences (Stohs et al., 2012) confirmed that p-synephrine supports metabolic rate and energy expenditure while maintaining a safe cardiovascular profile.
What makes CitrusBurn interesting is that it doesn't rely on a single ingredient. The formula pairs p-synephrine with capsaicin for additional thermogenic activation, green tea catechins to support fat oxidation, ginger to help regulate appetite and cravings, and apple vinegar extract for blood sugar stability. Each ingredient addresses a different piece of the weight management puzzle.
A closer look at each ingredient and what the available research says:
Primary active compound. Multiple peer-reviewed studies support its role in thermogenesis and fat oxidation. Reviewed in Obesity Reviews (Haaz et al., 2006).
Well-ResearchedStudied for satiety and blood sugar effects. A 2009 study in Bioscience, Biotechnology, and Biochemistry linked vinegar intake to reduced body weight.
Well-ResearchedWell-documented thermogenic properties. A 2012 systematic review in Appetite found capsaicinoids support energy expenditure and fat oxidation.
Well-ResearchedResearch in Metabolism (Mansour et al., 2012) showed ginger enhanced the thermic effect of food and promoted satiety in overweight adults.
Well-ResearchedExtensive research backing. A meta-analysis in International Journal of Obesity (Hursel et al., 2009) confirmed positive effects on weight loss and maintenance.
Well-ResearchedBerberine shows metabolic benefits, especially for blood sugar. Korean red ginseng supports energy and hormonal balance. Combined data for weight loss is growing.
Supported — Growing EvidenceWe looked at feedback from verified purchasers. Here's what stood out:
Says she'd tried "every powder and shake on the market" before CitrusBurn with nothing to show for it. Within two weeks, she noticed her jeans fitting looser — something she says almost made her emotional after years of frustration. Reports steady energy throughout the day with no jitters or crashes. Describes feeling like she finally has control over her body again.
Verified PurchaseHis biggest struggle was late-night eating — says it was ruining every diet he'd tried. Reports that the cravings faded noticeably within the first week on CitrusBurn. At his next doctor visit, his physician flagged improved wellness markers and asked what he'd changed. Says the 3 PM afternoon crash he'd lived with for years is completely gone.
Verified PurchaseHonest about her experience: says she didn't notice much in the first three weeks and considered giving up. But around week 4-5, her morning fog lifted and her energy shifted noticeably. Says she now wakes up and actually wants to move instead of dreading the day. Gave 4 stars instead of 5 because she wishes the results had come sooner, but says she's glad she stuck with it.
Verified PurchaseDescribes himself as "the guy who's tried everything and believes nothing." Went straight for the 6-bottle package after researching the ingredients. Over 8 weeks, says his midsection bloating went down significantly and his energy improved enough that his golf buddies started asking questions. Reports that his wife ordered her own supply after seeing his results.
Verified PurchaseBased on the ingredient profile, CitrusBurn appears generally well-tolerated. The stimulant-free formula eliminates common side effects like jitteriness or sleep disruption. Some users may experience mild effects initially:
Overall, CitrusBurn has one of the cleanest safety profiles we've reviewed in the thermogenic supplement category. The absence of stimulants, artificial fillers, and common allergens makes it a comfortable option for most adults.
