Vitamins are substances that our bodies need to develop and function normally. When considering vitamins, we tend to think of the usual suspects – A, C, D, E, and K, plus the eight B vitamins. However, the body produces many molecules that fit the description of a vitamin, driving physiological processes from infancy through later life. Some of these molecules might even be considered longevity "vitamins" – substances that extend healthspan and promote a longer life. In this Aliquot, I talk about three substances that may act as longevity vitamins – taurine, ergothioneine, and PQQ. This episode includes several key discussion points:

(03:09) Is taurine the key to Okinawan's long lifespans?
(04:49) How taurine promotes mitochondrial health
(06:05) How taurine deficiency impacts muscle mass
(06:41) Does supplementing the age-related decline boost longevity?
(08:58) Okinawa's High Intake vs. Japanese in Brazil
(10:01) Blood pressure, blood lipids, and glucose levels
(13:07) The role of ergothioneine in shielding membranes from oxidative damage
(15:14) How ergothioneine's unique lipophilic properties protect mitochondria
(19:18) Why some people transport ergothioneine better than others
(20:17) Whether to get ergothioneine from foods or supplements
(24:18) Is ergothioneine destroyed by cooking?
(25:02) The unusual antioxidant power of PQQ
(26:21) The role of PQQ in the brain
(29:12) PQQ's impact on NAD and sirtuin levels?
(30:37) Does PQQ blunt the positive effects of exercise?

For a deeper foray into this special topic, I highly recommend reading Dr. Bruce Ames' seminal paper, Prolonging healthy aging: longevity vitamins and proteins, published in the Proceedings of the National Academy of Sciences. This open-access article explores a range of compounds, including taurine, PQQ, and ergothioneine, which Dr. Ames identifies as potential longevity vitamins. The study provides valuable insights into how these vitamins and proteins could contribute to extending healthy lifespan. This episode features segments taken from several Q&As with Dr. Rhonda Patrick. You may view these episodes and their show notes here:

PREVIEW Aliquot #92: The Underestimated Role of Resistance in Body Recomposition Aug 11, 2023

Having a healthy body composition, with plenty of lean mass – in the form of muscle and bones – is essential for health throughout the lifespan. Achieving a healthy body composition requires a balanced approach that emphasizes resistance training – and calorie reduction where appropriate. In this Aliquot, Dr. Brad Schoenfeld describes a balanced approach to maximizing muscle growth and strength and dispels early myths about possible blunting effects of aerobic training, the need to train to failure, and the "go heavy or go home" philosophy. Here's what you'll find in this episode...

(00:00) Can resistance training amplify fat loss?
(03:33) Why weight loss burns muscle — and how to prevent it
(06:25) The role of protein in muscle preservation
(08:21) Does aerobic exercise blunt gains?
(16:07) The role of failure in resistance training
(18:29) Reps-in-reserve vs. training to failure
(24:37) Lighter loads and higher volume — an effective route to hypertrophy

PREVIEW Aliquot #65: Concerns with chronic NSAID use Aug 31, 2022

Non-steroidal anti-inflammatory drugs, or NSAIDs, are among the most widely used drugs worldwide, available in both prescription and over-the-counter forms, such as aspirin, ibuprofen, naproxen, and others. Most NSAIDs, with the exception of aspirin, work by inhibiting the activity of a family of enzymes called cyclooxygenases, which drive inflammatory processes. But because these inflammatory processes can be beneficial in some contexts and because the drugs often elicit off-target effects, there are some concerns about their use. In this Aliquot, I describe current recommendations and concerns surrounding NSAID use.

(00:00) Introduction
(02:58) Daily aspirin use and cardiovascular disease risk (clip from Q&A #9)
(07:02) The pros and cons of low-dose aspirin (clip from Q&A #30)

PREVIEW Aliquot #61: How dietary fiber influences metabolic health Jul 19, 2022

Dietary fiber is a broad term that refers to the non-digestible components of fruits and vegetables. Gut microbes break down certain types of fiber, releasing micronutrients trapped in the fiber matrix and producing beneficial metabolic byproducts, such as short-chain fatty acids. Fiber exerts a wide array of beneficial health effects, influencing metabolic health, and may be an important, if overlooked, component of ketogenic diets. In this Aliquot, Dr. Michael Snyder, Dr. Dominic D'Agostino, and Dr. Rhonda Patrick discuss the benefits of dietary fiber.

(00:00) Introduction
(00:44) The gut microbiome influences glucose and cholesterol regulation
(07:25) Benefits of including a variety of fibers on a ketogenic diet

PREVIEW Aliquot #59: How alcohol affects sleep, behavior, and cancer risk Jun 20, 2022

Alcohol, one of the most used drugs worldwide, is a controversial subject. Whereas some research suggests drinking alcohol improves health, an abundance of evidence indicates that drinking alcohol also harms health. Particularly, higher alcohol intake is associated with an increased risk of many cancers. Some of the deleterious effects of drinking may be due to alcohol's effects on sleep. Although alcohol may help us feel calm and ready to sleep, it has surprising effects on REM sleep and maybe our waking behaviors too. In this Aliquot, we discuss some of the risks and surprising effects of alcohol on human health and behavior.

(00:00) Introduction
(00:57) Multiple drinks per day increases the risk of many cancers (Member Q&A segments)
(07:16) Moderate alcohol consumption reduces cognitive impairment risk, heavy drinking increases it
(08:58) Mild alcohol intake increases the likelihood of living to 90 and improves insulin sensitivity
(11:30) Alcohol dampens autoimmunity, but increases infection risk
(12:07) Take-home messages about breast cancer

PREVIEW Aliquot #54: Dietary and environmental factors that may impact autoimmune diseases Apr 04, 2022

Autoimmune diseases such as type 1 diabetes, rheumatoid arthritis, and multiple sclerosis occur when the immune system mistakes the body's own proteins for those released by invading pathogens. The immune system has strategies for filtering these autoimmune cells out of circulation; however, this filter can malfunction due to age, genetic predisposition, disruption of the gut barrier and gut microbiota, or other environmental exposures. In this episode of the Aliquot podcast, we'll discuss autoimmunity and how childhood exposure to germs, dietary fiber intake, and fasting can build a healthy and balanced immune system.

(00:00) Introduction
(02:06) Childhood exposure to germs educates the immune system (Eran Elinav segment)
(08:51) Environment has more influence over the microbiome than genes
(12:42) The conversation between gut bacteria and the immune system (Sonnenberg segment)
(15:51) Fiber feeds friendly bacteria and attenuates immune overactivity
(19:15) Prolonged fasting resets autoimmunity (Valter Longo segment)

PREVIEW Aliquot #51: What's the best omega-3 dosage for maximum benefit? Feb 16, 2022

Early studies of omega-3 fatty acid intake demonstrated dramatic biological effects. Since then, the body of research enumerating the profound anti-inflammatory and multi-system, generalized health-promoting qualities of omega-3s continues to grow; however, some studies fail to show any effects from omega-3 supplementation. This source of consternation may, by and large, boil down to low doses, raising the question: what is the right dose of omega-3 to use? In this Aliquot, Dr. Bill Harris shares his experience administering some of the largest omega-3 doses ever used in human trials and gives his recommendations about optimal dosage taking genes and diet into account.

(00:00) Intro
(01:51) Tolerability of very high doses (25 grams or more)
(14:35) Why dose titration based on the RBC test is better than ball-parking
(15:58) The right dose for 95% of typical Westerner
(16:30) Why 4 grams might be better than 2 grams for some people

PREVIEW Aliquot #34: How fasting influences immune function Jul 01, 2021

This month’s Aliquot Preview episode features Dr. Rhonda Patrick and Dr. Valter Longo describe the roles that diet and fasting play in maintaining or restoring proper immune function.

Diet plays essential roles in immune function. Consequently, deficiencies or insufficiencies in vitamins or minerals can impair immune function. The gut microbiota also modulates immune function, so maintaining a healthy gut is crucial. However, when the immune system becomes overactive, autoimmune disorders can arise. A growing body of evidence indicates that the fasting-mimicking diet may be beneficial in treating autoimmune disorders.

PREVIEW Aliquot #25: Coffee, caffeine, and sleep Apr 01, 2021

Coffee consumption is associated with protection from several chronic diseases, including cancer, cardiovascular disease, and neurodegenerative disease. Whereas some of the beneficial effects of coffee may stem from its ability to induce autophagy, other evidence points to the benefits of caffeine, which, when consumed early in the morning – resets the body's internal clocks and provides a mental boost that helps us start the day and may even protect telomeres. But the long half-life of caffeine can reduce sleep quality, fueling a vicious cycle of poor sleep, daytime grogginess, and increased caffeine consumption. This Aliquot segment features Dr. Guido Kroemer, an expert in immunology, cancer biology, aging, and autophagy; Dr. Satchin Panda, an expert in circadian rhythm research; Dr. Matthew Walker, a professor of neuroscience and psychology; Dr. Elissa Epel, an expert in telomere biology; and Dr. Rhonda Patrick (in an interview with Mike Maser).

PREVIEW Aliquot #18: The dual nature of IGF-1: Striking a balance for optimal health Feb 25, 2021

Insulin-like growth factor-1, or IGF-1 for short, is a protein that plays critical roles in major growth pathways in the human body. It influences nearly every tissue in the body, especially developmental growth, skeletal muscle and neurons. Emerging evidence suggests that IGF-1 also regulates the aging process. Overactivity of IGF-1 has been implicated in aging and age-related diseases, such as cancer. Balancing the beneficial and (sometimes) harmful effects of IGF-1 via exercise and fasting is critical to maintaining health. In this episode, we discuss:

(00:00) Introduction
(03:23) The role of both mTOR and the IGF-1 pathway in cellular growth and their regulation by amino acids (Peter Attia discussion)
(11:50) Living longer as a function of preventing insidious damage to our cells and tissues

PREVIEW Aliquot #16: Time-restricted eating for better metabolic health - Part 1 Feb 25, 2021

Time-restricted eating, which involves taking in food within a small window of time during the day and fasting for the remainder, can improve certain biomarkers of health – even without weight loss – to improve overall health. In Part I of this two-part segment, Drs. Satchin Panda and Ruth Patterson describe how eating following the body's circadian clock – eating during the day and fasting at night – enables the body to focus on repair rather than on the digestion of food. In this episode, we discuss:

(00:00) Introduction
(01:05) Time-restricting eating reduces fat mass, increases lean muscle mass, reduces inflammation, and much more (Satchin Panda discussion)
(08:16) Maintaining a 9-12 hour eating window improves metabolism, increases muscle mass, and alters gene expression
(12:38) The benefits of intermittent fasting are independent of weight loss (Ruth Patterson discussion)

PREVIEW Aliquot #8: Lifestyle interventions for depression and anxiety Feb 25, 2021

This month’s Aliquot Preview episode features Dr. Charles Raison, a professor of psychiatry.

Various ancient practices, including meditation, hot yoga, and sauna, may aid in the treatment of depression. Whether the medical community will embrace these lifestyle interventions remains to be seen. In the meantime, most people with clinical depression are treated with antidepressants. These drugs have their advantages and disadvantages, and while they are helpful for a subset of depressed people, a quarter of patients taking the drugs may get worse.

In this clip, Dr. Charles Raison discusses his belief that ancient practices are more likely than modern pharmacology to encourage resilience and stave off depression and describes how antidepressants have their place in treating depression, but they should be used with caution due to some of their inherent side effects.

(00:00) Introduction
(02:01) Why some people respond to antidepressants while others don't
(09:48) Ancient wisdoms and traditions offer value in treating depression

PREVIEW Aliquot #6: Genetic and lifestyle risk factors for Alzheimer's disease Feb 25, 2021

The single most important genetic risk factor for Alzheimer's disease is a variant of apolipoprotein E, or APOE for short, a lipoprotein produced in the liver and brain. Roughly a quarter of all people living in the US – about 75 million people – carry a genetic variant of APOE called APOE4. Having APOE4 is associated with higher circulating levels of LDL cholesterol and an increased risk for Alzheimer's disease. But having APOE4 doesn't mean that Alzheimer's disease is inevitable. In fact, lifestyle behaviors can modulate risk for the disease, too, especially sleep, which provides an opportunity to rid the brain of toxic metabolic byproducts that can contribute to Alzheimer's disease risk. Understanding our genetic risks and addressing lifestyle behaviors – especially our sleep patterns – can influence whether a person eventually develops Alzheimer's disease. These Aliquot segments feature Dr. Dale Bredesen, a professor of neurology, and Dr. Matthew Walker, a professor of neuroscience and psychology.

(00:00) Introduction
(02:37) ApoE4 increases Alzheimer’s disease risk, but healthy habits can reduce risk (Dale Bredesen discussion)
(05:20) People who are ApoE4+ have 2x the risk of having sleep apnea (Matthew Walker segments)
(12:03) Glial cells are the sewage system for the brain
