Fluor in toothpaste

Fluoride in toothpaste has been a topic of debate due to its benefits and potential risks. Andrew Huberman explains that fluoride creates "supra-physiologically strong" bonds within teeth, making them more resistant to cavities and acid damage. This is why fluoride is commonly added to both toothpaste and drinking water 1 2.

However, concerns about fluoride's impact on brain health, thyroid function, and the oral microbiome have led some individuals to avoid it. In response, non-fluoride toothpaste options often contain hydroxyapatite, which naturally strengthens teeth through remineralization 1 3.

For those worried about fluoride exposure from tap water, using filtration systems can mitigate these concerns 4. Andrew Huberman himself opts for fluoride-free toothpaste and filters his drinking water to avoid potential risks 5.

The health risks of fluoride often center around its potential impact on thyroid and neurological health, particularly at high concentrations or with excessive exposure. Andrew Huberman highlights several key concerns related to fluoride:

1. Thyroid Function: High fluoride levels may disrupt thyroid hormone output and metabolism. Lower levels in drinking water are generally considered safe, but individual exposure can vary based on the amount of fluoride consumed through water and other sources 1.

2. Neurotoxicity: Fluoride's potential neurotoxic effects are debated. Some evidence, particularly from in vitro studies, suggests that high fluoride levels can be toxic to neurons. However, the impact at common exposure levels is less clear 2.

3. Oral Microbiome: There is some data suggesting fluoride might negatively impact the oral microbiome, although this area needs more research 3.

4. High Dose Toxicity: At very high concentrations, fluoride is a poison. Andrew Huberman shares a personal anecdote about swallowing fluoride during a dental visit as a child, resulting in acute toxicity and vomiting 4.

Overall, while fluoride is effective at preventing tooth decay by strengthening enamel, its potential risks underscore the importance of monitoring overall fluoride intake and considering individual circumstances when deciding on its use in toothpaste and drinking water 5 6.

Andrew Huberman does not consistently use fluoride toothpaste. He shared that he sometimes avoids fluoride toothpaste and instead uses brands featuring hydroxyapatite and xylitol, especially due to personal concerns about fluoride's potential health impacts. As part of his oral hygiene routine, he sometimes opts for non-fluoride toothpaste options, including toothpaste tablets 1 2 3.

Andrew Huberman has shared several insights on ashwagandha, highlighting its benefits and usage considerations:

1. Stress and Anxiety Reduction: Ashwagandha has a powerful anti-anxiety effect and is known to significantly reduce cortisol levels, offering relief to those experiencing chronic stress. In some studies, reductions in cortisol ranged from 14.5% to 27.9% 1.

2. Health Benefits: Lower cortisol levels achieved through ashwagandha can lead to numerous downstream health benefits such as improved cardiovascular health, reduced heart palpitations, increased thyroid hormones, and decreased symptoms of anxiety and compulsive behaviors 2.

3. Hormonal Effects: Ashwagandha may also boost testosterone levels indirectly by reducing cortisol, which generally allows testosterone levels to rise. This herb can support various hormone systems, enhancing fertility and libido 3.

4. Dosage and Timing: It's common for Andrew Huberman to take ashwagandha in the evening to help with sleep and reduce chronic stress. He recommends checking reputable sources like examine.com for dosage guidelines and suggests a cautious approach to supplementation, typically advising against chronic use without breaks 2 4.

5. Caution Against Chronic Use: Andrew Huberman advises not to use ashwagandha continuously for more than two weeks at a time due to potential disruptions in other hormone and neurotransmitter pathways. Strategic and temporary use is recommended for optimal benefits and to avoid adverse effects 5 4.

Ashwagandha can be a potent tool for managing stress and supporting hormonal health, but it should be used thoughtfully and under appropriate guidance.

Ashwagandha offers several benefits, driven largely by its ability to reduce cortisol levels and its adaptogenic properties:

1. Stress and Anxiety Reduction:

   • Ashwagandha has a significant anti-anxiety effect, reducing cortisol levels by 14.5% to 27.9% in stressed individuals 1.
   • It also helps decrease symptoms associated with psychological stress, such as fatigue and cognitive impairment 2.

2. Improved Cardiovascular Health:

   • Lowered cortisol can lead to better cardiovascular health, reducing markers like C-reactive protein, which is linked to negative health effects 3.

3. Hormonal Balance:

   • Ashwagandha can increase testosterone levels, likely through the reduction of cortisol, thus supporting fertility and libido 4.
   • It also positively impacts thyroid hormones (T3 and T4) 3.

4. Enhanced Memory and Cognitive Function:

   • By improving sleep, which is often disturbed by high cortisol, ashwagandha can lead to better memory and reaction times 3.

5. Physical Health and Performance:

   • This adaptogen has been shown to enhance power output in athletes and modestly adjust cholesterol levels 1.

6. Adaptogenic Effects:

   • Adaptogens like ashwagandha blunt cortisol levels, aiding in relaxation and better sleep quality when taken at the right times during the day 5.

Dr. Huberman suggests taking ashwagandha in the evening to avoid interference with the natural cortisol spike needed in the morning for energy. He advises against chronic, long-term use without breaks due to potential negative impacts on other systems, such as liver and thyroid function 6 3.

These benefits make ashwagandha a valuable tool for managing stress, improving overall health, and supporting hormonal balance when used appropriately.

Creatine has been discussed extensively on the Huberman Lab, covering its benefits, effects, and various uses. Here are some key insights:

• Cognitive and Brain Functions: Andrew Huberman highlights creatine's role in brain function, particularly its ability to serve as a fuel source in the brain. Creatine supplementation can enhance brain function, especially in people who do not consume meat or other dietary sources rich in creatine. It may also impact mood regulation and motivation by enhancing certain frontal cortical circuits. This is particularly beneficial in contexts like depression 1 2.

• Traumatic Brain Injury (TBI): In a pilot study, creatine supplementation showed significant benefits in reducing the frequency of headaches, dizziness, and fatigue in individuals with traumatic brain injury. The study used higher doses than those typically used for muscle performance, demonstrating a remarkable decrease in headache frequency from 90% to about 10-12% in those taking creatine 3 4.

  Creatine for Brain Function

  Andrew Huberman

  Andrew discusses how creatine, a compound found in meat sources and supplements, can improve brain function and enhance certain frontal cortical circuits that connect to areas of the brain involved in mood regulation and motivation. He also mentions that creatine supplementation can be especially useful for people who do not consume meat or other sources of foods that are rich in creatine.
