I do not have the packaging of the Kruidvat sport multi at hand, but if its composition is somewhat comparable to the other Kruidvat multi's, I wouldn't expect much from it. The same applies to virtually all other store-brand multivitamins, as well as well-known brands like Davitamon and Supradyn. These types of products really contain a minimal amount of the vitamins you need, and the minerals are generally poorly absorbed. Absolutely not comparable to most multivitamins on our site.

Just as insufficient sleep can lead to fatigue, too much sleep can also give a tired feeling. If you are between 25 and 35 years old, then 8 hours per night is more than sufficient. If you are older, you may only need 6 or 7 hours, and sleeping longer may only make you feel groggy. The most refreshing way to start the day is with a fruit breakfast. A "hearty breakfast" can actually be groggy-inducing, especially if it contains difficult-to-digest combinations like cheese and such. Try starting the day with a light, hydrating meal (various types of fruit, possibly supplemented with cucumber, avocado, and tomato) and have your first substantial meal (grains, dairy products) only a few hours after getting up.

Once your Sport Vitamins are finished, it would be better to switch to an orthomolecularly formulated supplement, such as the Multi Vitamins Pro. Or if you are looking for a multi with an extra high dosage of B vitamins (energy!), the Mega-One™ Multiple from Source Naturals.

An herb that radically increases both physical and mental energy levels is Rhodiola, which you can use alongside your daily multivitamin.
