Supplements aren't necessary for everybody. However, many people derive tremendous benefit from them. They can be used for enhancing sleep and the depth of sleep, enhancing focus and cognitive ability, enhancing energy, adjusting hormone levels to optimal range, and even for gut microbiome support. It's important to note that if you're going to take supplements, you want to know what's working for you and what isn't. Therefore, single ingredient formulations can be very useful. They allow you to figure out which supplement ingredients are most essential and only use those. But remember, not all supplement companies independently test their products, so it's crucial to choose ones that ensure the quality and accuracy of their ingredients.
