Lymph Tonic Side Effects & Safety

The formula contains nattokinase, so medication interactions and bleeding risk deserve more than a boilerplate disclaimer.

Can we predict side effects from the label?

Not precisely. Individual doses are not disclosed, and people vary in medication use, allergies and medical history. We therefore avoid promising that the product is “side-effect free.”

Nattokinase and bleeding risk

Memorial Sloan Kettering reports that nattokinase may increase bleeding risk with blood-thinning drugs and lists anticoagulant, antiplatelet and fibrinolytic therapy among important concerns. It also advises caution for people with clotting disorders and a history of deep vein thrombosis.

Before using Lymph Tonic

• Review the complete current label.
• Ask a healthcare professional or pharmacist about medication interactions.
• Do not use a supplement to self-treat unexplained swelling or suspected lymphedema.
• Seek individualized advice if pregnant, nursing, planning surgery or managing a medical condition.
