Tongkat Ali and Blood Pressure: Is It Safe?
Last updated: 2026-09-24
Quick answer
Human studies at typical doses (200 to 400 mg per day of standardised extract) have not reported meaningful increases in blood pressure. However, people with high blood pressure, heart conditions, or who take regular medication should check with their doctor first.
What the studies report
Clinical trials of standardised water extract generally reported Tongkat Ali as well tolerated over 4 to 12 weeks, with no serious side effects. Recent systematic reviews reached a similar conclusion while noting that long-term studies are limited.
Who should speak to a doctor first
- People with high blood pressure or heart disease
- People taking blood pressure, blood thinner, diabetes or hormone medication
- People with hormone-sensitive conditions, including prostate conditions
- Anyone under 18
The bigger risk: unregistered products
The Malaysian and Singapore health authorities regularly find unregistered 'herbal' products laced with undeclared prescription drugs, which can affect blood pressure and heart health. Always check for a KKM MAL registration number. Nuviton is registered as MAL24066122T.
