  • Diagram of molecular structure of Docosahexaenoic acid (DHA)
    Essential Fatty Acids | Fatty Acids & Lipids

    Docosahexaenoic acid – DHA

    DHA, or docosahexaenoic acid, is a type of omega-3 fatty acid, which are fats that are important for our health. DHA is vital for brain health and function, as well as eye health. Our bodies can’t produce enough DHA on their own, so it’s essential to get it through our diet or supplements. Foods rich in DHA include fish like salmon and tuna, and some types of algae.

    Ginkgo Biloba

    Ginkgo Biloba is a type of tree. It has been growing on earth for hundreds of millions of years. It’s a living fossil. Its leaves are used to make an extract that people consume to improve functional brain performance.

    Lucid Thinking

    In the simplest of terms, ‘lucid’ can be defined as clarity in thought and communication. It refers to the ability to express ideas in a clear, unambiguous manner, or to understand concepts or situations with ease. It often describes a state of mental transparency or coherence, where thoughts are easy to understand and articulate.

  • Human memory - diagram of working memory by functional brain region.
    Cognitive Outcomes | Nootropics & Cognitive Enhancers

    Memory

    Memory is how your brain stors information for recall, later. It’s your own special filing system where it keeps information you’ve learned and experiences you’ve had. Sometimes you can recall this information easily, and sometimes you might find it hard to remember.

  • Molecular Structure of Creatine (neutral)
    Cellular Energy Metabolism | Energy Systems

    Creatine

    Creatine is a type of substance our bodies naturally produce, and we use it to give our muscles energy when we exercise or do hard things. It’s also found in foods like meat and fish, and many people take it as a supplement to work out harder and build muscles easier. It’s a powerful compound.

    Blood-Brain Barrier

    The blood-brain barrier is like a security guard for your brain. It’s a special wall made up of cells that protects your brain from harmful things in your blood, like germs or poisons. But it also lets good things, like oxygen and nutrients, get through to keep your brain healthy.

  • Brain Derived-Neurotrophic Factor (BDNF) Production Mechanism
    Brain Function Neurochemistry | Neurotransmitters & Neurochemistry

    BDNF

    BDNF stands for Brain-Derived Neurotrophic Factor. In simpler terms, it’s a protein that functions a lot like fertilizer for our brain. Just like how fertilizer helps plants grow stronger, BDNF helps our brain cells grow, connect and stay healthy. When our brain has more of this special protein, learning, memory, and thinking all get a boost.

  • Percent of US population reporting "brain fog" 2019-2024
    Cognitive Outcomes | Nootropics & Cognitive Enhancers

    Brain Fog

    Brain Fog is a term used when you’re feeling like you can’t think clearly or focus. You might feel confused or just “Out of it”.
    In reality, fog (low, dense water vapor) obscures vision. Brain “fog” is a metaphor for lack of cognitive clarify or when you find it difficult to concentrate or remember information that you previously knew, and had less trouble recalling. You might forget things easily, struggle to make decisions, or have trouble finding the right words to say.
