Nutritional Breakdown: What's Inside Silk Almond Milk?

Silk almond milk is a processed plant-based beverage with varied nutritional content depending on the flavor and fortification. Unlike whole almonds, which are nutrient-dense, the milk is largely filtered water with a small percentage of almonds, so it relies on fortification to be a robust milk alternative.

Unsweetened Silk Almond Milk

The unsweetened variety is often considered the healthiest choice. It is naturally low in calories and carbohydrates, containing no added sugar. Silk fortifies this milk to boost its nutritional value, making it a viable option for those looking to manage weight or blood sugar levels.

Calories: Approximately 30 calories per cup.
Sugar: 0g of sugar per serving.
Protein: Low in protein, typically around 1g per cup.
Fortification: Often enriched with vitamins A, E, D, and B12, along with calcium.

Original and Flavored Silk Almond Milk

Calories: Can contain 60+ calories per cup, depending on the flavor.
Added Sugar: Varies by product, but can be substantial in sweetened versions.
Protein: Remains low, similar to the unsweetened option.
