Vitamin A is a fat-soluble vitamin that aids in healthy vision, a strong immune system, and healthy reproductive system. Vitamin A is often added to breakfast cereals and milk, which aren’t typically consumed on the ketogenic diet.
Good news: there are plenty of healthy ways to make sure you’re getting enough vitamin A – without reaching for the cereal bowl. Try eggs, wild-caught salmon, spinach, and beef liver.
