Why we made it
Everyone plans for a long life. Almost no one plans for a strong one.
We have all watched it happen to someone. A life that got smaller a little at a time, and nobody could say exactly when it started.
That is not the argument for eating well. The argument is still being on the trail at seventy. Still lifting the grandchild. Still the one who books the trip, and still sharp enough to be difficult about the itinerary.
It has a name. Healthspan is the years lived in good health, free from chronic disease, pain, and disability. Lifestyle determines far more of it than genetics, and three behaviors carry most of the weight: how we eat, how we move, how we sleep.
Moving and sleeping ask for time. Eating asks for attention, all day, every day. One meal a day gets it, planned and prepared and usually worth it. The rest get whatever is left.
Field Theory is one complete meal a day, made from the whole foods with the strongest evidence behind them for healthspan.
Healthspan is built, not inherited.
Nutrition feeding the biology of healthspan
Six systems. One daily meal.
Muscular & Metabolic
26g complete protein from yellow pea, brown rice, and pumpkin seed supports muscle maintenance. B vitamins and chromium (105% DV) support energy metabolism.
Brain & Cognitive
1,005mg polyphenols from matcha, wild blueberries, aronia berries, and turmeric help protect brain cells from oxidative stress. 147mcg carotenoids and iron (45% DV) support cognitive health.
Cardiovascular & Circulatory
1,650mg omega-3s from flax and chia support heart health. Plant sterols support healthy cholesterol balance, and 11g fiber supports cardiovascular health as part of a diet low in saturated fat and cholesterol.
Digestive & Microbiome
11g fiber from flax, chia, acacia, guar, pumpkin, and leafy greens feeds beneficial gut bacteria and promotes regularity. Six diverse whole food sources, not isolated psyllium or inulin.
Immune & Cellular Defense
Zinc (100% DV) from seeds and selenium (90% DV) support normal immune cell activity. Vitamins C and E, plus beta-glucans from whole maitake and shiitake mushrooms, help protect cells from oxidative damage.
Skeletal & Structural
The four bone nutrients that depend on each other, in one meal: calcium (25% DV) from leafy greens, vitamin D (65% DV) from UV-exposed mushrooms, vitamin K (150% DV) from kale and spinach, magnesium (45% DV) from pumpkin seeds.
How We Built It
We started from the science. Not from a trend.
Field Theory is what happens when someone does the work of figuring out which foods, in which amounts, actually deliver.

How Field Theory compares.
For Ka'Chava Chocolate, and AG1 Next Gen. August 2026.
Tastes like food. Because it is.
Subtly sweet with hints of vanilla and nut. Smooth, not chalky or gritty. The kind of meal you look forward to.
Mix 2 scoops with 12-16 oz cold water. Ready in 60 seconds.
One Decision. Done.
One meal. Real food. Every day.
Common questions.
What does Field Theory replace?
The rushed meal. A protein bar, a handful of something between meetings, or nothing at all. Field Theory turns one of those into a complete whole food meal in 60 seconds.
Each serving delivers 26g protein, 11g fiber, 25 vitamins and minerals from food, plus polyphenols (antioxidants) and omega-3s (healthy fats) that most meals lack. You may not need those protein powders, fiber and greens supplements, and multivitamins anymore. Your cabinets will thank you.
And it does all this for $4.00 per meal, less than half the cost of the groceries needed for similar nutrition.
Is Field Theory a meal or a supplement?
A meal. Field Theory is a conventional food made from 27 whole food ingredients. Our label has a Nutrition Facts panel, not a Supplement Facts panel. Every vitamin and mineral comes from the food itself, not from a synthetic premix. That distinction matters: supplements fill nutrient gaps, while Field Theory prevents those gaps in the first place.
