Safety starts with the label
The Flexigenics label advises adults to take one capsule daily with 6–8 oz of water and says not to exceed the recommended dose. It also advises pregnant or nursing individuals, children under 18 and people with a known medical condition to consult a physician before use.
Vitamin K2 and anticoagulants
Vitamin K plays an important role in blood clotting. People taking warfarin or similar vitamin-K-sensitive anticoagulant therapy should not make major changes to vitamin K intake without medical guidance.
Green tea extract
Concentrated green tea extracts are different from drinking ordinary green tea. Extracts have been associated with gastrointestinal effects and, rarely, liver injury. Anyone with liver disease or taking medications should discuss concentrated botanical extracts with a professional.
Pregnancy, nursing and minors
The product label specifically recommends physician consultation for pregnant or nursing individuals and says the product is not for children under 18.
