Frequently Asked Questions
Product
What is the Field Theory shake?
The Field Theory shake is a nutritionally complete daily meal made entirely from whole foods. To make it simple and convenient to prepare (and eliminate those pesky excuses), we offer it as a ready-to-mix powder. Mix with water, give it a shake, voila.
Why do you formulate only from whole foods?
The health benefits documented in major dietary pattern trials (PREDIMED, DASH, MIND) come from food, not from isolated nutrients. Nutrients in whole foods are embedded in a physical and chemical matrix of fiber, cell walls, and fatty acids that modulates absorption and biological effect. A vitamin in food behaves differently than the same vitamin in a tablet.
Most nutrition shakes start with a synthetic vitamin premix and work backward to meet label targets. Field Theory starts with the dietary patterns that research shows work, selects the whole foods that deliver those nutrients, and verifies every batch. The result is 27 recognizable ingredients. Nothing synthetic or artificial.
What are the benefits of using Field Theory?
A daily Field Theory shake makes it easy to get whole food nutrients like fiber, protein, polyphenols, and omega-3s in amounts that help maintain and build muscle, support metabolic and cardiovascular health, and maintain gut integrity.
What makes Field Theory different from other nutrition products?
Field Theory is real food and a nutritionally complete meal, not a dietary supplement. Key nutrients are in clinically meaningful amounts, not trace amounts. We do not use any synthetic or artificial ingredients, or cheap, off-the-shelf premixes. We are crafted to support the biology of good health. We tell you exactly how much of key compounds like polyphenols, carotenoids, and omega-3s are in each serving.
How does it taste?
A Field Theory shake is subtly sweet, with hints of vanilla and nut. Smooth, not chalky or gritty. The kind of meal you look forward to.
Who's behind Field Theory?
Kevin Appelbaum founded our company with a team of clinicians, food scientists, and product developers who've spent decades focused on improving health through better nutrition.
Fun Fact: Kevin's last company developed new treatments for diet- and age-related diseases using whole food nutrition and technology, and pioneered the first FDA-approved treatment for type 2 diabetes that wasn't a drug. He is now focused on using preventive nutrition to support good health.
Is Field Theory a dietary supplement?
No. While supplements can help address nutrient deficiencies, Field Theory is a nutritionally complete meal designed to prevent deficiencies in the first place.
Usage
How do I make a Field Theory shake?
Easy. As a meal, mix 2 scoops with 12 to 16 oz of cold water, then shake or blend. For a quick and healthy snack, mix one scoop with 8 oz of water.
Do I need to drink Field Theory 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 meaningfully, and polyphenol intake reaches levels rarely seen in American diets.
What does Field Theory replace?
Field Theory replaces most supplements, lower-quality nutrition shakes, and overly processed convenience foods.
Most nutrition shakes are made from synthetic vitamin premixes and a sweetened protein base. Trace amounts of whole foods may be added to support packaging claims using words like "superfoods, greens, omegas, antioxidants" and so on. Or the very impressive sounding "90+ superfoods" implying that more is better. But in most cases, these ingredients are like pixie dust: used in such small amounts, they offer little to no benefit.
Will a Field Theory 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.
Ingredients, Nutrients & Benefits
What ingredients are in a Field Theory shake?
You can find detailed information on our Ingredients page.
Do your shakes contain sugar or other sweeteners?
Field Theory is sweetened with Organic Coconut Palm Sugar and small amounts of Stevia. It also contains Organic Vanilla Bean and Natural Flavors. Total added sugar is 4g per serving.
What ingredients do you avoid using?
We do not use any of the following in our products: soy, dairy, gluten, lab-made synthetic vitamins, artificial colors, flavors, or sweeteners, corn syrup, sugar alcohols like erythritol, carrageenan, genetically modified organisms, psyllium, inulin, or animal products.

Where can I find detailed nutrition information?
You can find the complete Nutrition Facts panel and ingredient list on our Ingredients page. For a deeper look at what each nutrient does and where it comes from, visit our Benefits page.
Are all of the ingredients organic?
Not yet. Currently, 84% of our ingredients are USDA-certified organic (by weight). All of our ingredients are free of genetically modified organisms (non-GMO).
What are polyphenols, and why do they matter?
Polyphenols are a type of phytonutrient naturally occurring in colorful fruits, vegetables, and herbs that help the body manage oxidative stress and inflammation. They play a key role in supporting brain health, circulation, and cellular resilience across multiple systems. Field Theory delivers 1,005mg per serving.
Quick Fact: Most adults consume 50 to 70% less polyphenols than levels associated with reduced risk of cognitive decline, inflammation, and chronic disease.
What are omega-3 fatty acids, and why do they matter?
Omega-3 fatty acids support brain, heart, and joint health. They support cognitive function, help regulate inflammation, and support long-term cardiovascular health. Field Theory delivers 1,650mg of ALA omega-3 from flax and chia seeds.
Quick Fact: More than 90% of U.S. adults fall short on omega-3 intake, despite research linking adequate levels to a 30 to 40% lower risk of cognitive and cardiovascular issues.
Which vitamins and minerals are most important for good health?
Vitamins and minerals like B vitamins, vitamins C, D, E, K, magnesium, iodine, zinc, and selenium power enzyme systems, antioxidant defenses, and structural maintenance. Field Theory provides 25 vitamins and minerals at 20% Daily Value or higher, all from whole food sources.
What does complete protein mean, and why does it matter?
A complete protein contains all nine essential amino acids that the body can't make on its own, making it vital for maintaining muscle, metabolism, and tissue repair. Getting enough high-quality protein is important to help maintain and build muscle, support metabolic health, and maintain physical function. Field Theory provides 26g of complete protein from pea, brown rice, and pumpkin seed.
Quick Tip: After age 40, adults can lose up to 1 to 2% of muscle mass per year, yet nearly half fall short on daily protein needs, and 80% don't get enough resistance exercise to protect strength and function. Protein alone isn't enough. Muscle needs both nutrition and use to stay strong.
Why is fiber important?
Fiber helps maintain healthy blood sugar and cholesterol levels, supports weight management, and nourishes the gut microbiome, which is linked to immune and inflammatory regulation. Field Theory provides 11g from six diverse whole food sources.
Quick Fact: Adults should get 25 to 38 grams of fiber per day, but fewer than 1 in 10 Americans meet that target.

Why is there a Prop 65 sticker on my package?
California's Prop 65 requires a warning label if a product may expose consumers to any of over 900 substances, many of which occur naturally in plant-based ingredients. Every batch of Field Theory is tested to ensure that heavy metals remain well below FDA safety limits.
What testing do you do to ensure safety?
Every ingredient and every final batch is tested for identity, quality, and purity, including microbial contaminants and heavy metals. A third-party lab tests each production batch in accordance with FDA guidelines to verify that the actual nutrient amounts match label claims.
