What Customers Are Saying
"Finally. A shake without tons of weirdo ingredients. I don't need a multivitamin. I need food. Field Theory gets it right."
"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."

FAQs
How is Field Theory different than other nutrition products?
Most nutrition shakes start with protein isolates, add synthetic vitamins to hit label numbers, then list dozens of extracts for marketing appeal. Field Theory is 27 whole food ingredients. Every vitamin and mineral comes from food, not a premix. Every nutrient amount is verified by third-party testing. It is a complete meal, not a supplement.
Do I need to drink a Field Theory shake every day?
You don't have to, but consistency is where the benefit builds. Most people use it as a reliable daily meal, typically breakfast or lunch. Two scoops, cold water, 60 seconds. The goal is to make good nutrition automatic so you don't have to think about it.
How do subscriptions work?
Subscribe and save $10 per pouch ($79.99 instead of $89.99) with free shipping on every order. You choose your delivery frequency. You can pause, skip, or cancel anytime from your account. You'll get a reminder before each shipment so there are no surprises.
What products does it replace?
One Field Theory shake replaces a meal, a multivitamin, a fiber supplement, and a greens powder. That is typically $150 or more per month in separate products. Field Theory delivers all of it from whole food sources in one serving for $5.33 per meal.
How does it taste?
Subtly sweet and light with hints of vanilla and nut. It is not thick, chalky, or artificially flavored. Mix two scoops with cold water in a shaker bottle. Add ice after mixing for the best texture. Most people are surprised by how easy it is to drink every day.
Will a shake keep me full?
Yes. Each serving has 26g of protein, 11g of fiber, and 9g of healthy fats. That combination keeps you full for 3 to 4 hours. It is a 290-calorie meal, not a snack or a supplement.
