The Polyphenol Gap
Research suggests 1,000-1,500mg per day of polyphenols is associated with benefits for cardiovascular health, cognitive function, and healthy aging. But most adults consume 50-70% less.
Premium supplements can deliver isolated polyphenols such as quercetin, resveratrol, or curcumin. But they don't deliver broad-spectrum, quantified polyphenols from multiple whole food sources at therapeutic levels.
Field Theory does. 1,005mg per serving from wild blueberries, aronia berries, matcha, leafy greens, and turmeric.
One shake. Complete nutrition. $99/month.

What People Are Saying
"As a physician, I appreciate Field Theory’s whole-food, phytochemical-rich ingredients. The texture is rich with a surprisingly mild, enjoyable taste. While stevia isn’t my favorite, blending it with raw cocoa and ice makes a perfect mid-afternoon lift."
"Finally. A shake without tons of weirdo ingredients. I don't need a multivitamin. I need food. Field Theory gets it right."
"I’ve tried a lot of meal replacements and protein powders, and this one stands out. It’s smooth, satisfying, and actually leaves me feeling full, not reaching for a snack an hour later. It tastes good, the ingredients are clean, and it does what a meal replacement should do."
"Nice flavor, not too sweet, and blends well. I usually feel pretty hungry soon after drinking a smoothie/protein shake, but this is fiber-filled and sticks with me longer. I've been using as a post-work meal and after a long run or hard workout to help with my recovery."
"At 63, I'm still surfing, doing jujitsu, skiing, and lifting. The same activities I've loved since rowing in college. Field Theory's science-based formula provides the nutrition I need to maintain my lifestyle without a cabinet full of supplements or the mental load of tracking everything."
"This is my in-between meetings, packed work day life-saver! I put cold water in my travel mug, give it a good shake, and that’s it. Doesn’t clump, doesn’t need anything else, easy to sip and go."
"Work keeps me always on the go. My nutritionist recommendeded Field Theory, and it has become my go-to breakfast every other day, and whenever I’m traveling."
"I love knowing that Field Theory gives me everything my body needs in one simple shake. Blended with chopped ice, it tastes incredible and keeps me fueled through long days building my business."
