Put lemon juice, almond milk, collagen, stevia, salt, and vanilla in blender. Turn on low for just a few seconds to mix. While blender is on low, slowly add in glucomannan. Blend on low for 30 seconds and turn off. Add in strawberries and ice cubes, blend on high until completely blended.
If you split this drink with a loved one you can add an additional tablespoon of collagen so that you are both getting a good serving of protein.
