The darker your skin, the more likely you are to need vitamin D supplements. While light skinned people only need about 20 minutes of sun per day to get their dose, people with very dark skin may need two hours or more. Consider a supplement to ensure you're getting enough vitamin D.
Consider whether you need to take thiamin, or vitamin B1, when eating healthy. You may be deficient in thiamin if you experience fatigue, weakness, psychosis, or nerve damage. It can be found in asparagus, whole grains, pork, oranges, and spinach. However, since it's water soluble, it may be lost during cooking due to water loss. If that is an issue for you, there are thiamin supplements.
Focus on whole grain cereals for breakfast. Cereal is a great way to start your day and most are full of the vitamins and minerals your body needs. You will not only start your day with a great supply, but also give yourself a great energy boost. Avoid sugary cereals for best effect.
