Micronutrients & recovery

Kefir consumption improves lactose digestion and reduces flatulence severity in individuals with lactose malabsorption, performing similarly to plain yogurt.

If you get bloated or gassy from milk, try kefir. It contains natural enzymes that break down the lactose, so you get the nutrients without the stomach upset. One study showed it caused less gas than milk and was just as easy to handle as yogurt.
