High-speed shaking blends air into the shake. The foam is just trapped bubbles.

What Causes Froth?

Whey Protein 

Whey isolates and hydrolysates tend to foam more readily due to their faster solubility and smaller particle size, which signifies their purity.

Overshaking or using a blender can trap more air. So mix it gently or stir with a spoon.

Water causes more froth than milk. Opt for almond milk or oat milk for a smoother shake.

Type of Liquid Matters

Room-temperature water or milk is shown to cause less froth. Chill it after preparing it.

Give your shake 1–2 minutes after mixing, and let the froth settle naturally.

Some shaker bottles have anti-froth mesh or compartments, and actually, it is worth the upgrade.

It is not at all harmful, but it can cause bloating or make the drink feel unpleasant. If I share an insight, froth is a sign that your protein is pure and of good quality.
