Cissus Quadrangularis Extract
Also known as: Cissus Extract, Vitis quadrangularis, Veldt Grape, Adamant Creeper
Cissus quadrangularis is a traditional plant extract standardized to ketosterones, primarily studied for bone health and joint support in both animal and limited human research. Evidence remains preliminary, with most human studies showing modest effects on bone metabolism and fracture healing.
Primary uses
- Bone health support
- Joint and connective tissue support
- Fracture recovery
- Bone density maintenance
How it works
- Ketosterone compounds may modulate bone-specific alkaline phosphatase and osteogenic pathways
- Potential anti-inflammatory effects on joint tissue
- May support collagen synthesis in connective tissue
Dosage
- Typical range
- 1,000-3,500 mg daily (of extract)
- Timing
- Divided doses with meals
- With food
- Recommended with food for better absorption
- Duration
- Studies typically evaluated 4-12 weeks; long-term safety beyond 12 weeks not well established
- Special populations
- Insufficient safety data in pregnancy/lactation; avoid if hypercalcemic or have kidney disease
Forms
- Standardized extract (40% ketosterones)· 70/100
- Powder· 70/100
- Capsule· 70/100
Safety
Common side effects
- Generally well tolerated
- Mild gastrointestinal upset reported in some studies
- Headache (rare)
Contraindications
- Hypercalcemia or parathyroid disorders
- Severe kidney disease
- Pregnancy and lactation (insufficient safety data)
- History of kidney stones (theoretical risk)
Evidence notes
Limited human clinical trial data; most evidence comes from animal studies and a small number of human studies with modest sample sizes. Some positive findings for bone metabolism markers and fracture healing, but larger, well-controlled RCTs are needed. Standardization to ketosterones is appropriate but research is not extensive.
Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
