Brain Fog to Improve Focus

In the modern, fast-paced world, brain fog is a prevalent issue affecting many individuals. It can hinder productivity, impair cognitive function, and make it challenging to stay focused. Fortunately, there are effective solutions available in the form of vitamins that can help combat brain fog and enhance mental clarity. Instead of focusing on specific product solutions, in this post, we will explore the 8 best sources for brain fog solutions, backed by scientific research, to improve focus and cognitive performance.

Vitamin B Complex - The Cognitive Energizer

Vitamin B complex comprises a group of essential vitamins, including B1, B2, B3, B5, B6, B9, and B12, all of which play a crucial role in brain function. These vitamins are involved in converting food into energy, which is essential for maintaining brain health. Vitamin B6, for instance, aids in producing neurotransmitters such as serotonin and dopamine, crucial for mood regulation and focus. By replenishing B vitamins through dietary supplements, brain fog can be effectively reduced, leading to improved mental alertness and cognitive performance. Our favorites are:

  • B1 Benfotiamine as BenfoPure®
  • B2 Riboflavin as Riboflavin 5’-phosphate
  • B3 NADH as PANMOL® NADH-high potency Niacin
  • B5 Panthethine as Pantesin® CoEnzyme A
  • B6 Pyridoxine as Pyridoxal 5’-phosphate
  • B9 Folate as Metafolin® as L-5-Methyltetrahydrofolate (5-MTHF)
  • B12 in two versions—methylcobalamin and Adenosylcobalamin.

Vitamin D - The Sunshine Vitamin for Brain Clarity

Vitamin D, often referred to as the sunshine vitamin, is known for its role in maintaining bone health. However, emerging research indicates that vitamin D is also vital for brain function. Deficiency in vitamin D has been linked to cognitive decline and an increased risk of neurodegenerative disorders. Ensuring adequate vitamin D levels through supplements or safe sun exposure can help alleviate brain fog and promote better focus and concentration. Our favorite is:

  • Vitamin D3 as cholecalciferol

Vitamin C - The Antioxidant Shield for the Brain

As a potent antioxidant, vitamin C plays a crucial role in protecting the brain from oxidative stress and inflammation. It aids in neutralizing harmful free radicals that can damage brain cells and impair cognitive function. By incorporating vitamin C-rich foods or supplements into the diet, individuals can enhance their brain's resilience, combat brain fog, and sharpen their focus. We like:

  • Whole vitamin C complex Polyphenol-C®

Vitamin E - Preserving Cognitive Health

Vitamin E is another powerful antioxidant that supports brain health. It protects cell membranes from oxidative damage and helps maintain healthy blood circulation to the brain. Studies suggest that vitamin E supplementation may slow down cognitive decline and improve memory retention. By incorporating vitamin E into their regimen, individuals can combat brain fog and maintain optimal brain function. Our favorite here is:

  • Vitamin E tocotrienols as DeltaGold®

Magnesium - Relaxing the Brain and Body

Magnesium is a mineral that plays a crucial role in various physiological processes, including nerve function and muscle relaxation. A deficiency in magnesium can lead to increased stress and anxiety, contributing to brain fog. Supplementing with magnesium can promote relaxation, reduce stress, and improve focus by calming the nervous system. We like around 500mg of magnesium malate.

Ginseng - Herbal Brain Booster

Ginseng, a popular herbal remedy, has been traditionally used to enhance mental clarity and cognitive function. Research suggests that ginseng may improve memory, concentration, and attention span. By incorporating ginseng supplements or herbal teas into their routine, individuals may experience a reduction in brain fog and an enhancement in their ability to concentrate.

MCTs (Medium Chain Triglycerides)

MCTs are a type of saturated fat that consists of fatty acids with 6-12 carbon atoms. Unlike long chain fatty acids which require digestion in the small intestine and transportation through the bloodstream, MCTs are rapidly absorbed and transported directly to the liver where they are converted into ketones. MCTs provide the brain with a quick and efficient source of energy that can enhance cognitive function. Studies have shown that MCTs can improve memory, focus, and concentration in both healthy adults and those with mild cognitive impairment. MCTs may also help protect the brain from damage by reducing inflammation and oxidative stress—thus supporting brain health and enhancing mental clarity.


If you're looking for a natural and effective way to enhance your brain clarity and energy, then ketones might be the answer you've been searching for. Ketones are molecules produced by the liver when the body runs low on glucose (sugar) as a source of energy. They are generated from stored fats and can be used as an alternative fuel by the brain and other tissues. Ketones come in 3 types: beta-hydroxybutyrate (BHB), acetoacetate (AcAc), and acetone. BHB is the primary ketone in the blood, while AcAc and acetone are mainly byproducts of BHB metabolism. Ketones have been studied for their potential benefits for brain function, metabolic health, and longevity.


Brain fog can significantly impede daily life and hinder optimal cognitive performance. Incorporating the right vitamins and supplements into one's routine can be an effective way to combat brain fog and improve focus. The 8 best sources for brain fog solutions discussed in this post—including Vitamin B Complex, Vitamin D, Vitamin C, Vitamin E and  Magnesium (found in Dr. Tennant's® Restore), MCTs and Ketones (found in Dr. Tennant's® Brain Food), and Ginseng—can provide essential support for maintaining a clear and focused mind. However, it is essential to consult a healthcare professional before starting any new supplement regimen to ensure safety and effectiveness.
