FAQs
How is Field Theory different than other nutrition products?
Here are a few of the ways:
• Field Theory is a food, not a supplement
• All nutrients are naturally occurring in our whole food ingredients; we do not use any synthetic (lab-made) or artificial ingredients
• We are crafted to support the biology of aging in midlife adults; we are not an all in one for everybody and everything shake
• We tell you exactly how much of key healthy-aging compounds like polyphenols, carotenoids, and omega-3s are in each serving
Do I need to drink a Field Theory shake every day?
With rare exceptions, consistency is the most effective approach for optimal nutrient absorption and long-term health. With consistent use, many report steadier late-morning energy and fewer cravings. Protein intake to start the day becomes consistent, fiber increases by about one-third, and polyphenol intake reaches levels rarely seen in American diets.
How do subscriptions work?
While you can place a one-time order, most of our members prefer a continuity plan where you save on each bag, receive convenient automatic shipments, and have full control over your delivery frequency.
Here are some of the benefits:
- Save 10% off each bag
- Flexible delivery every 4, 6, or 8 weeks
- Cancel any time
- No hidden fees
- Easily pause, delay, or change order frequency
- No surprises with pre-shipment reminders
What products does it replace?
Field Theory replaces most supplements, lower quality and general purpose protein and nutrition shakes, and overly processed convenience foods.
Did you know? Most nutrition shakes are made from synthetic (lab-made) vitamin premixes and a sweetened protein base. Trace amounts of whole foods may be added to support packaging claims using words like "whole foods, superfoods, greens, omegas, antioxidants..." and so on. Or the very impressive sounding "80+ ingredients" implying that more is better. But in most cases these whole food ingredients are a bit like pixie dust, and in such small amounts, they offer little to no benefit.
How does it taste?
A Field Theory shake is slightly sweet, with hints of vanilla and nut.
Will a shake keep me full?
Yes. The combination of 26g of protein and 11g of fiber in each serving slows digestion and helps you feel full longer.
