The science-backed secret to brain longevity & performance*
improve learning, memory, & cognitive performance*
Think fast: powerhouse neuronutrient Cognizin® citicoline is critical for neurotransmitter production and neuronal health and function at any age. Featured in its full-potency dose, it benefits learning, memory, and cognitive performance. It has also been clinically shown to increase mental ATP energy, brain cell membrane phospholipid formation, mental processing speed, and the ability to tune out distractions.*
support executive function & cognitive flexibility*
Find serenity, now, with the ultimate nootropic botanical. Our Zembrin® kanna (Sceletium tortuosum) extract is sustainably sourced from South Africa. Used for millennia, this indigenous plant helps balance brain waves and key neurotransmitters like serotonin. Zembrin® is also clinically shown to improve executive function and cognitive flexibility. It also enhances mental well-being and mood by strengthening resilience to stressful stimuli. Peace out and find your happy place.*
enhance brain blood flow & mental processing speed*
Here’s to resveratrol, the buzzworthy antioxidant working hard for your brain. A powerful polyphenol, ours is fermentation-derived, producing potent antioxidant actions fighting oxidative stress and fostering cellular resilience, mitochondrial health, and longevity. Its unique nitric oxide-mediated vasoactive properties and cerebrovascular benefits are clinically shown to increase blood flow to the brain and enhance processing speed, verbal memory, and cognitive task performance. For more light bulb moments—and less forgetting to turn the lights off.*

    Is Brain Guard safe to take when pregnant?


    Hi Faith, thank you for taking the time to leave a review! Most mbg supplements+ are safe for pregnant and breastfeeding women (with the exception of metabolism+). With that being said, if you are pregnant or breastfeeding or planning to become pregnant, out of an abundance of caution, we recommend consulting your healthcare practitioner before using any dietary supplement products. All the best. - mindbodygreen
