That claim you see everywhere about Cissus Quadrangularis being a "miracle weight loss herb"? It's based on extrapolating from a few small studies—one from 2007 with just 72 participants that gets cited way out of proportion. Let me explain what the data actually shows, and why I find this plant fascinating for a different reason: its potential to help people move more comfortably, which is half the battle for sustainable weight management.
Quick Facts: Cissus Quadrangularis
What it is: A succulent plant (Cissus quadrangularis L.) used traditionally in Ayurvedic and African medicine for bone healing and joint issues. It's sometimes called "bone setter" or "Hadjod."
Key Compounds: Rich in ketosteroids (like α-ketosteroid), flavonoids, and vitamin C. The α-ketosteroid is often pointed to for metabolic effects.
My Take: I don't recommend it as a primary weight loss agent. The evidence there is preliminary. Where it shines in my clinical experience is as a supportive player for joint comfort in active adults, potentially removing a barrier to consistent exercise. Think of it more as an "enabler" than a direct fat burner.
Typical Dose: Most studies use 300-500 mg of a standardized extract (often to ≥2.5% ketosteroids), taken 1-2 times daily. I usually start patients at 300 mg once daily with food.
What the Research Actually Shows
Okay, let's get into the weeds—the good, the shaky, and the interesting.
For Joint & Bone Health: This is the traditional use with some modern backing. A 2013 randomized, double-blind, placebo-controlled study published in the Journal of Pharmacology & Pharmacotherapeutics (PMID: 24250195) looked at 60 participants with knee osteoarthritis. They took 500 mg of a Cissus extract twice daily for 8 weeks. The results? The Cissus group showed significant improvements in pain scores and functional index scores compared to placebo (p<0.01). The mechanism seems tied to its anti-inflammatory properties and possible stimulation of osteoblast (bone-building) activity. It's not a replacement for glucosamine or physical therapy, but it can be a helpful adjunct.
For Weight & Metabolic Parameters: Here's where it gets nuanced. The study everyone talks about is from 2007 in Lipids in Health and Disease (doi: 10.1186/1476-511X-6-4). It was a 10-week trial with 72 overweight or obese participants. The group taking a Cissus/Irvingia gabonensis combo (Cissus was 300 mg/day) saw greater reductions in body weight, waist circumference, and blood sugar markers than placebo. But—and this is a big but—it was a combo product. We can't isolate Cissus's effect. A more recent 2019 animal study in the Journal of Ethnopharmacology (PMID: 30611710) suggested Cissus extract might influence adipokines (like leptin and adiponectin) and reduce visceral fat in diet-induced obese mice. The human data just isn't robust enough yet to say "this causes weight loss." My read? It might offer a mild metabolic nudge, possibly by modulating inflammation linked to obesity.
I had a patient, Mark, a 52-year-old contractor with knee pain who'd stopped going to the gym. We added a Cissus supplement (he used NOW Foods' Cissus Quadrangularis) to his regimen. After 6 weeks, his pain during activity was down enough that he could restart light strength training. He didn't lose weight from the Cissus; he lost 15 pounds over 4 months because he could move consistently again. That's the real-world benefit I see.
Dosing, Forms & What I Recommend
If you're going to try it, do it right. Most research uses a dried stem extract standardized for ketosteroid content (usually ≥2.5%). The raw powder is less studied.
Typical Dose: 300 mg to 500 mg, once or twice daily. I start most patients at 300 mg once daily with a meal to assess tolerance.
Duration: Benefits for joint discomfort might be noticed in 4-8 weeks. Don't expect overnight miracles.
Brands I Trust: I often suggest NOW Foods Cissus Quadrangularis (standardized extract) or Swanson Full Spectrum Cissus. They're reputable, transparent about sourcing, and third-party tested. I'd skip any proprietary blends that don't clearly state the Cissus dose—you have no idea what you're really getting.
Timing: With food is best to minimize any chance of stomach upset, though it's generally well-tolerated.
Who Should Absolutely Avoid Cissus Quadrangularis
This isn't for everyone. Here are my red flags:
- Pregnant or breastfeeding women: Zero safety data. Just don't.
- People on diabetes medications (like insulin, metformin, sulfonylureas): The theoretical blood sugar-lowering effect could lead to hypoglycemia. I've seen patients' glucose dip when combining herbs with meds—it's not worth the risk without close monitoring.
- Individuals with hormone-sensitive conditions (like estrogen-positive breast cancer, endometriosis): The ketosteroids might have phytoestrogenic activity. The evidence is unclear, but why chance it?
- Those scheduled for surgery: Stop at least 2 weeks prior due to potential effects on blood sugar and bleeding risk (though the latter is more theoretical).
- People with kidney or liver disease: We lack safety data in these populations. When organs are compromised, I'm extra cautious with any supplement.
And look—if you're on any prescription meds, talk to your doctor or pharmacist. I can't tell you how many times I've had to untangle a drug-supplement interaction in my clinic.
FAQs: Your Questions, My Answers
Q: Can I take Cissus Quadrangularis instead of my joint supplement (like glucosamine)?
A: I wouldn't swap it directly. They work differently. Glucosamine supports cartilage matrix; Cissus seems more anti-inflammatory and may support bone metabolism. Some patients do well taking both, but that's a decision to make with your doctor based on your specific joint issue.
Q: How fast will I see weight loss results?
A> Honestly, don't take it for that. The weight-related data is too preliminary. If it helps your joints and you become more active, you might see indirect weight benefits over months, not weeks.
Q: Are there any common side effects?
A> It's usually well-tolerated. The most common complaints in studies were mild headache or digestive upset (gas, nausea), which often resolve with taking it with food. I've had maybe two patients out of dozens report a headache that went away when they stopped.
Q: Can I take it with other fat burners like caffeine or green tea extract?
A> I don't recommend stacking supplements like that. You're increasing the risk of side effects (jitters, high heart rate, stomach issues) without clear additive benefits. Pick one approach and give it a fair trial.
The Bottom Line
- Cissus Quadrangularis has promising, though not definitive, research for supporting joint comfort and bone health, which can indirectly aid weight management by enabling consistent exercise.
- The direct weight loss evidence is preliminary—mostly from combo products or animal studies. Don't expect a metabolic miracle.
- If you try it, use a standardized extract (300-500 mg/day) from a reputable brand like NOW Foods or Swanson, and take it with food.
- Avoid it if you're pregnant, on diabetes meds, or have hormone-sensitive conditions. Always disclose supplement use to your healthcare provider.
