We need to look after our brain health

Here are some of the ways brain alertness supplements are thought to work:

• Increasing Blood Flow and Oxygenation: Some nootropics, such as Ginkgo biloba, may act as vasodilators, which means they widen blood vessels in the brain. This can increase cerebral blood flow, allowing the brain to receive more oxygen and nutrients, which are essential for energy production and overall brain function.
• Modulating Neurotransmitters: Neurotransmitters are chemical messengers in the brain. Certain supplements may influence their levels or activity.
  • Acetylcholine: This neurotransmitter is crucial for learning and memory. Some supplements, like choline bitartrate and phosphatidylcholine, are precursors to acetylcholine, meaning they provide the raw materials for the brain to produce more of it.
  • Dopamine and Norepinephrine: These neurotransmitters are linked to mood, motivation, and attention. Stimulants like caffeine and some prescription drugs work by increasing the release or inhibiting the breakdown of these chemicals.
  • Glutamate: This is a major excitatory neurotransmitter involved in cognitive processes and synaptic plasticity. Some nootropics may modulate glutamate receptors, which can enhance learning and memory.
• Supporting Brain Energy Metabolism: The brain is a high-energy organ. Some supplements may support the metabolic activity of mitochondria, the “powerhouses” of brain cells. This can help ensure that neurons have the abundant energy they need to function properly.Providing Neuroprotection and Antioxidant Support: The brain is vulnerable to oxidative stress and damage from free radicals. Some nootropics contain antioxidants that may help protect brain cells from this damage and inflammation, which is thought to be a factor in age-related cognitive decline. Examples include curcumin and certain B vitamins.Promoting Neuroplasticity: This refers to the brain’s ability to reorganize itself by forming new neural connections. Some supplements may support this process by providing the building blocks for new neurons and maintaining the flexibility of cell membranes.
