A traditional medicinal vine, long used to help mend broken bones, now a low-cost supplement marketed for bone strength, joint comfort, and weight management. The human evidence is real but modest: it may ease fracture- and exercise-related joint pain, with weight and blood-sugar benefits leaning on multi-ingredient products. Short-term safety looks favorable. (Full Review)

Protocol

Standard Dose

500–3,200 mg daily

Standardized stem extract; bone/joint use clusters at 500–1,000 mg, joint-pain pilot used 3,200 mg.

Timing & Splitting

With food, split doses

Taken with food to reduce GI upset; ≥1,600 mg split into two or three administrations.

Start Low & Titrate

Begin ~500 mg daily

Increase gradually toward 1,000–3,200 mg over 1–2 weeks if tolerated.

Time to effect

Joint & Metabolic Goals

~8 weeks

Joint-pain and metabolic studies generally run 8 weeks.

Bone-Focused Use

Up to 24 weeks

Bone trials extend to 24 weeks.

Realistic Trial Period

8–24 weeks

A realistic trial period before judging response.

Benefits

Medium: Fracture-healing and bone-pain support; joint-pain reduction in active adults

Low: Weight and waist-circumference reduction; improved blood lipids and fasting glucose

Speculative: Antioxidant and general anti-inflammatory support; cardiometabolic and vascular protection

Contraindications

Pregnancy and breastfeeding

Transplant recipients and immunosuppressed individuals

Bleeding disorders or scheduled surgery (stop at least 2 weeks before surgery)

Hormone-sensitive conditions

Key Interactions

Antidiabetic drugs (metformin, sulfonylureas such as glipizide, insulin)

Antihypertensive drugs (ACE inhibitors such as lisinopril, ARBs such as losartan, calcium-channel blockers)

Immunosuppressants (tacrolimus, mycophenolate, ciclosporin)

Over-the-counter medications (NSAIDs such as ibuprofen, blood-sugar or weight-loss aids)

Supplement interactions (Irvingia gabonensis, berberine, chromium)

Risk & Side Effects

Low: Gastrointestinal upset; headache and insomnia

Speculative: Thrombocytopenia in immunocompromised use; effects in pregnancy and hormonal sensitivity; blood-sugar and blood-pressure lowering

Monitoring

Marker	Target	Why
Fasting blood glucose	70–85 mg/dL	Detects additive blood-sugar lowering and tracks metabolic benefit
HbA1c	< 5.4%	Confirms sustained glycemic effect over time
Lipid panel (LDL, triglycerides, total/HDL)	LDL < 100 mg/dL; triglycerides < 90 mg/dL	Tracks the lipid improvements seen with combination products
Bone turnover markers (e.g., CTX and P1NP)	Mid-reference for age/sex	Reflects effect on bone remodeling, which trials show before density changes
Serum parathyroid hormone (PTH)	15–45 pg/mL	Meta-analysis shows the plant can raise PTH; useful to watch in bone users
25-hydroxyvitamin D	40–60 ng/mL	Ensures adequate vitamin D to support any bone benefit
Platelet count	150–400 ×10⁹/L	Screens for the rare thrombocytopenia concern, mainly in higher-risk users

Cadence: Baseline check, reassessment at ~8 weeks for joint or metabolic goals and ~3–6 months for bone-focused use, then every 6–12 months if continued.

Qualitative Assessment

Joint pain and stiffness during and after exercise
Recovery time and swelling after training or injury
Energy levels and general well-being
Digestive comfort (to detect early gastrointestinal side effects)
