Ginger Root Extract
Also known as: Zingiber officinale, ginger extract 5% gingerols, ginger rhizome extract, gingerols
A concentrated extract of ginger rhizome standardized to gingerols, the pungent compounds responsible for most of its studied effects. Meta-analyses of randomized trials support its use for nausea, including pregnancy-related nausea at doses below 1,500 mg per day, and for joint comfort in osteoarthritis. It is a versatile ingredient that appears in digestive, joint, and motion-comfort products, and its warming flavor is easy to build around in powders and gummies.
Research summary
Gingerols and shogaols act on serotonin 5-HT3 receptors in the gut and modulate prostaglandin and leukotriene synthesis, which is associated with reduced nausea and inflammatory signaling.
