Ranked on dose, testing and labels as well as cost in the best boswellia supplements.
Why the cheapest is not the best buy
Knee trials tested named extracts, 5-LOXIN and AprèsFlex, at 100 mg a day or more (Sengupta 2008; Vishal 2011). The lower-cost products here use other extracts or a blend, so a cheaper serving buys milligrams of a different thing. See what the research found.
Take the label serving. If you take any medicine, or are pregnant or breastfeeding, ask your doctor first.
