However, she notes that if you are already supplementing with fish oil, you will still get the phospholipid form of DHA. Buying expensive caviar is not necessary, as there are other options available in grocery stores. The discussion also includes plant-based compounds, EPA, DHA, and a third category of Omega-3s. The speaker advises against eating fishing bait as a source of Omega-3s.
Vitamin D & Sun Skin Exposure
Vitamin D is a crucial nutrient produced in the skin when exposed to sunlight, but factors like skin color and sunscreen use can affect its efficiency. Supplementation is important for those with darker skin or limited sun exposure. Vitamin D deficiency is prevalent in the US population and is associated with increased mortality. Maintaining vitamin D levels between 40-60 nanograms per milliliter is ideal. Sun exposure can increase hormone levels, as the skin is an endocrine organ.
Role of Vitamin D, Gene Regulation
Vitamin D plays a crucial role in gene regulation, stimulating more than 5% of the protein-encoded human genome. It activates tryptophan hydroxylase-2, influencing serotonin production in the brain. Additionally, it may regulate the gene responsible for producing tryptophan hydroxylase-1 in the gut. Serotonin, regulated by this gene, is important for immune function, blood pressure, water retention, and bone health. With a high percentage of the US population deficient in vitamin D, supplementing with vitamin D3 may be crucial for addressing various health issues.
Tool 6: Vitamin D Testing & Vitamin D3 Supplementation
Vitamin D3 supplementation is important for maintaining optimal levels of vitamin D in the body. The recommended dosage varies for individuals, and it is crucial to get tested to determine the appropriate amount. Vitamin D3 can be obtained from both animal and plant sources, such as fatty fish and fortified foods like milk and plant-based milk alternatives.

Tool 9: Deliberate Cold Exposure Protocol & Mood/Anxiety
Deliberate cold exposure protocol has been shown to have positive effects on the body, even with just 20 seconds of immersion in cold water. The optimal time and temperature for cold exposure is 20 seconds at 49 degrees Fahrenheit. Cold exposure leads to increases in epinephrine, adrenaline, dopamine, and cortisol. It also has lasting mood-enhancing effects and can reduce anxiety. Cold exposure causes vasoconstriction, resulting in a shock to the system. The release of norepinephrine during cold exposure impacts neurotransmitters and mood. There is a correlation between cold exposure and its effect on mood and anxiety.
Tool 10: Cold Exposure, Mitochondria UCP1 & Heat Generation
Cold exposure leads to cold adaptation, increasing the body's heat generation efficiency through the activation of the UCP1 gene and subsequent production of heat by mitochondria. Norepinephrine plays a role in activating UCP1. Shivering is an inefficient method of heat production compared to the more effective activation of UCP1. Mitochondria function like batteries, with a negative charge on the inside and a positive charge on the inner membrane. Uncoupling in mitochondria occurs during cold exposure, where the positive charge leaks out, resulting in heat production instead of ATP. Uncoupling is a more efficient method of heat generation compared to shivering. With repeated cold exposure, individuals can transition from shivering to uncoupling for thermogenesis.
Tool 11: Cold & Fat ‘Browning’, PGC-1alpha, Metabolism
Exposure to cold can lead to the production of more mitochondria in adipose tissue, a process regulated by the protein PGC-1alpha. This increase in mitochondria is known as "browning" of fat, as it makes the fat cells appear darker under a microscope. Browning fat can have thermogenic characteristics, meaning it burns glucose and fatty acids to produce heat. By exposing oneself to cold, it is possible to activate beige fat, which also has thermogenic qualities. Brown fat and beige fat can affect metabolism, and researchers are actively studying ways to harness their effects for potential therapeutic use.
- Cold exposure promotes fat 'browning' and increases mitochondria production in adipose tissue and muscle.
- Browning fat burns glucose and fatty acids to produce heat.
- Cold exposure can activate beige fat, which also has thermogenic qualities.

Sauna use can have positive effects on mood and stress management. The heat stress of the sauna releases endorphins, which improve mood. Sauna use also releases dynorphin, which can cause a dysphoric feeling. Despite this, sauna use has been shown to improve anxiety and stress levels.
- Sauna use releases endorphins, feel-good opioids that improve mood.
- Sauna use also releases dynorphin, an endogenous opioid that can cause a dysphoric feeling.
- Despite the release of dynorphin, sauna use has been shown to improve anxiety and stress levels.
- The speaker hypothesizes that sauna use may have a similar effect to binding dynorphin to the kappa opioid receptor, resulting in a longer-lasting release of endorphins and potentially improving mood.
Tool 14: Mild Stress, Adrenaline & Memory
The relationship between mild stress, adrenaline, and memory is explored in this video. The release of norepinephrine during mild stress, such as being in a sauna or cold exposure, can enhance memory and learning. James McGaw's work shows an inverted U-shaped relationship between adrenaline and memory, with an optimal level of stress improving memory and retention. Mild stress activates the release of adrenaline, which enhances memory consolidation and retrieval. It is important to maintain stress levels within a healthy range for overall well-being.
Sauna, Vasodilation & Alzheimer’s and Dementia Risk
Sauna use has numerous benefits for cognition, cardiovascular health, and reducing the risk of dementia and Alzheimer's disease. Here are the key points:

Tool 17: Exercise & Longevity, Osteocalcin
The relationship between exercise and longevity, specifically focusing on the effects of exercise on the brain, is discussed in the transcript snippets. Both individuals emphasize the importance of exercise for brain health and cognitive function. They highlight how exercise promotes creativity, problem-solving, and mental clarity. Exercise also plays a role in maintaining muscle mass for healthy aging. Load-bearing exercise, like endurance work, releases osteocalcin from the bones, which can travel to the hippocampus and promote the growth of neurons and synapses. This suggests that an active body signals the brain for cognition. In contrast, an inactive body deprives the brain of signals about the body's activities. Sharing exercise protocols is important to improve health and longevity.
Tools 18: Red Light Sauna? Infrared Sauna? Sauna & Sweating of Heavy Metals
The use of red light in saunas, specifically infrared saunas, is the topic of discussion. While there is frustration with red light saunas not getting hot enough, red light and low-level light therapies have shown positive effects on biology. Red light is believed to penetrate deep layers of the skin and potentially affect mitochondria. Infrared saunas, which use red light wavelengths, have been shown to improve cardiovascular health and can help excrete heavy metals through sweating. Regular saunas provide cardiovascular benefits through heat stress, while infrared saunas offer affordability and reduced fire hazards. Hot baths can also be a good alternative for heat stress.
