Flax Milk & Hydration
Flax milk is a lightweight, omega-3 rich plant milk. Here is how this seed-based beverage supports your hydration.
Flax milk is a plant-based milk made from cold-pressed flaxseed oil or ground flaxseeds blended with water. It is one of the lowest-calorie plant milks available, with unsweetened versions containing only 25-50 calories per 8 oz. The milk is approximately 91-94% water, making it exceptionally efficient for hydration. Flaxseeds are the richest plant source of alpha-linolenic acid (ALA), an omega-3 fatty acid, and the milk retains meaningful amounts. The flavor is very mild and neutral, making flax milk versatile in cooking, baking, and beverages. Most commercial versions are fortified with calcium, vitamin D, vitamin A, and vitamin B12.
