The Core Base: Ultra-Filtered Milk
At the heart of every fairlife protein shake is their signature ultra-filtered milk. This unique process is what sets fairlife apart from many other ready-to-drink protein supplements, which often rely on protein powders mixed with water. The ultra-filtration technique concentrates the naturally occurring milk proteins—approximately 80% casein and 20% whey—while removing a significant portion of the lactose sugar. The result is a richer, creamier milk with a higher protein and calcium content and less sugar than traditional milk. This provides a clean, dairy-based protein source for muscle recovery and daily nutrition.
Sweeteners, Flavorings, and Additives
To achieve their distinct taste while maintaining a low sugar profile, fairlife shakes use a combination of sweeteners and natural flavorings. For example, the Fairlife Nutrition Plan vanilla flavor includes:
- Natural Flavors
- Lactase Enzyme (to ensure lactose-free status)
- Monk Fruit Juice Concentrate
- Stevia Leaf Extract
- Sucralose
- Acesulfame Potassium
The use of these low-calorie sweeteners allows for a sweet taste without the added sugars found in many other beverages. However, some sources, like the Environmental Working Group (EWG), note that the use of artificial and low-calorie sweeteners is a point of consideration for some consumers.
Stabilizers for a Creamy Texture
To ensure a smooth, consistent texture and prevent separation, fairlife includes several stabilizers and thickeners in its formulas. These ingredients are common in many food products and contribute to the shake's pleasing mouthfeel:
- Cellulose Gel
- Cellulose Gum
- Carrageenan
- Maltodextrin
- Sodium Hexametaphosphate (in some variants)
While functional, the inclusion of ingredients like carrageenan has also been flagged by certain organizations for potential inflammatory effects in some individuals, though it is approved for use by food safety authorities.
Fortification with Essential Vitamins and Minerals
Beyond the core protein and calcium naturally present in the ultra-filtered milk, fairlife shakes are fortified with additional vitamins and minerals to boost their nutritional value. Standard fortification includes:
- Vitamin A Palmitate
- Vitamin D3
Different fairlife product lines may have slightly different nutritional profiles, but these vitamins are standard additions to support overall health and the body's use of calcium.
