Clinical Cognition By Natural Clinician Overview & Drug Interactions

Alpha-GPC (alpha-glycerylphosphorylcholine) is a natural compound found in small amounts in foods such as soy lecithin, and is also available as a dietary supplement. It is a source of choline, a nutrient that is important for brain health and function. Alpha-GPC is particularly known for its potential to improve cognitive function, particularly in the areas of memory and learning. It is also being studied for its potential to improve symptoms of Alzheimer's disease and other forms of dementia. Alpha-GPC is likely better absorbed and utilized in the body than other sources of choline as it is known to cross the blood-brain barrier. The choline provided from Alpha-GPC is also a precursor to acetylcholine, an important neurotransmitter for cognitive functions such as attention, memory, and learning.

Turmeric is a commonly used spice and a member of the ginger family (Zingiberaceae). It is native to India and other parts of South Asia and is known for its bright orange-yellow color and its warm, slightly bitter flavor. In traditional medicine, turmeric is believed to have a number of health benefits due to its high content of antioxidants and other compounds, such as curcumin. It is thought to have anti-inflammatory and antimicrobial properties, and it is often used to treat a variety of conditions, including joint pain, digestive problems, skin disorders, and respiratory infections. Most dietary supplements that utilize turmeric standardize their products based on a specific amount of curcumin (curcuminoids) per dose. Additionally, turmeric supplements are often paired with black pepper extract (piperine) to improve oral absorption.

Green tea is a type of tea that is made from the leaves of the Camellia sinensis plant. It is native to Asia and is widely consumed throughout the world. Green tea has a mild, slightly grassy flavor and is typically lighter in color and less astringent than black tea. Green tea is a rich source of antioxidants, particularly a group of compounds called catechins. These antioxidants are thought to help protect cells from damage caused by free radicals. Green tea is also a good source of other nutrients, including vitamin C and several B vitamins. Green tea is often consumed for a number of purported health benefits including reducing the risk of heart disease, immune-stimulating effects, and weight loss. Oral green tea supplements, containing dried powder, are most often utilized for the caffeine content and used as an appetite suppressant for weight loss.

Ginkgo (Ginkgo biloba) is a tree native to Asia and is known for its distinctive fan-shaped leaves. The extract of the ginkgo leaf is commonly used in traditional medicine and is one of the most popular dietary supplements consumed worldwide. Its most common use is to help improve memory and cognitive function.

Phosphatidylserine is a phospholipid that plays a crucial role in cell structure and function, particularly in the brain. It's a key component of cell membranes, aiding in cell signaling and maintaining cellular integrity. In the context of the brain, phosphatidylserine supports cognitive function, memory, and neurotransmitter regulation. Additionally, it's commonly used as a dietary supplement to potentially enhance cognitive performance and mitigate age-related cognitive decline.

Vinpocetine is a synthetic compound that is derived from the alkaloid vincamine, which is found in the periwinkle plant (Vinca minor). It is used as a dietary supplement and is claimed to have a number of potential health benefits, including improving memory and cognitive function, increasing blood flow to the brain, and reducing inflammation. The Food and Drug Administration (FDA), in 2019, issued a warning that those who are pregnant or who could become pregnant should avoid vinpocetine due to safety concerns.

Vitamin B12, also known as cobalamin, is a water-soluble vitamin crucial for several bodily functions. It plays a pivotal role in the formation of red blood cells, aiding in the prevention of anemia. Vitamin B12 is essential for maintaining a healthy nervous system and proper brain function, as it is involved in the synthesis of myelin, the protective sheath around nerve fibers. This vitamin is primarily found in animal-based foods such as meat, fish, dairy products, and eggs, making it important for vegetarians and vegans to consider supplementation. A deficiency in vitamin B12 can lead to neurological issues, fatigue, and cognitive impairment.
