Immune health – Quercetin is a flavonoid found in plants like apples. It promotes a healthy immune response in the face of seasonal immune challenges, which makes it the perfect addition to your stay-healthy regimen. Quercetin also helps inhibit oxidative stress.
Cardiovascular health – This ability to inhibit oxidative stress (as well as promote a healthy inflammatory response) makes quercetin good for your cardiovascular system. It encourages endothelial health and with it, helps maintain healthy blood pressure already in normal range.
Superior absorption – So why is it that quercetin isn’t more popular. It’s because this nutrient is difficult for your body to absorb. Our Bio-Quercetin formula integrates quercetin into a phytosome—a tiny sphere made out of plant-based lipids (think sunflower seed oil). This makes our quercetin up to 50 times more bioavailable than standard quercetin.

Youthful energy levels – It's a fact: as we age, our cellular energy levels decline—mainly because our mitochondria, the powerhouse of our cells, aren't functioning the way they did when we were younger. L-Carnitine is an amino acid produced in your body that plays an important role in supporting the optimal functioning of your mitochondria—so you can reclaim that youthful energy.
Keep that metabolism going – As we age, levels of carnitine decline in all of our tissues, which affects metabolic activity in addition to our cellular energy. Boosting carnitine levels with L-Carnitine can help you maintain youthful metabolic activity.
Anti-aging must-have – In addition to supporting cellular energy and metabolic activity, L-Carnitine also helps you support already-healthy blood pressure, maintain a healthy body fat composition and promote your brain cell defenses against age-related memory and cognitive decline. It’s the perfect way to show that age really is just a number!
Why our lipoic acid is “super” - Most supplements use a 50/50 ratio of the active “R” form of lipoic acid, which means it’s challenging for your body to absorb it fully. But based on numerous studies, we’ve developed Super R-Lipoic Acid which includes a highly bioavailable form of lipoic acid. The biologically active “R” form of lipoic acid reaches higher blood concentration sooner than standard R-lipoic acid. This gives your body more of this nutrient to use, and more time to use it so that you
Keep the energy flowing - The highly bioavailable “R” form of lipoic acid in Super R-Lipoic Acid has remarkable antioxidant properties. It helps protect your mitochondria from oxidative stress caused by free radicals, promoting healthy mitochondrial function and encouraging youthful cellular energy.
High bioavailability, rapid intake - Bioavailability is the time it takes for an ingested supplement to reach the bloodstream—as well as how much of it gets absorbed. The more bioavailable a supplement is, the more beneficial it is. Our innovative Super R-Lipoic Acid formula has up to 30 times the bioavailable levels of standard R-lipoic formulas. It’s designed to ensure rapid uptake from the plasma into the tissues—all in an easy-to-swallow capsule.

YOUTHFUL MEMORY & COGNITION AT ANY AGE - Maintaining optimal brain health is key to promoting cognitive performance, especially as we age. We combined ashwagandha, pregnenolone, phosphatidylserine, vinpocetine, sage and wildcrafted whole blueberry fruit extract to lay the ground work for healthy brain cells and overall cognitive function.
Product Note: Exposure to heat or sunlight may lead to melting/damage of product. Hence customers are expected to be available during the product delivery
MENTAL FOCUS AND AN UPBEAT MOOD - We added the neurohormone pregnenolone to help maintain healthy, youthful cognitive function—this includes attention and memory performance. In fact, pregnenolone has even been thought of as a neurotransmitter (brain chemical messenger), and it’s been shown to support a positive mood. One way pregnenolone may be able to accomplish all this is by encouraging synaptic plasticity, which is a key characteristic of youthful brain function.
BLUEBERRIES TO ENHANCE COGNITIVE FUNCTION - Our formula features high-quality blueberries that are high in antioxidants. These phytonutrients (the compounds found in blueberries) can help inhibit age-related decline in cognitive and motor function. Moreover, wild blueberry extracts have been shown to encourage a healthy inflammatory response and to have powerful antioxidant properties, protecting brain cells from oxidative stress.
