Daily Value (Dr. William Wallace)

White matter, composed largely of myelinated nerve fibers, facilitates communication between different brain regions. Damage to white matter, observed (i.e., lesions) via MRI, is associated with cognitive decline and increased dementia risk. Plasma concentrations of omega-3 fatty acids in epidemiological research is associated with a reduced burden of white matter lesions (WML)

An RCT published in Neurology (PMID: 39088212) this August looked at the effects of omega-3 supplementation on white matter lesions (size of which can be indicative of neurodegenerative diseases like Alzheimer’s) in adults aged 75 and over.

This study examined whether supplementing with omega-3 fatty acids daily (from 2014-2019) could slow the progression of WML in older adults with low baseline omega-3 levels.

Findings:

• Fish Oil Benefits: reduction in WML progression not statistically significant across the entire cohort. However, participants with the APOE ε4 allele (genetic marker linked to a higher risk of Alzheimer’s) experienced a significant decrease in neuronal integrity breakdown when supplemented with omega-3s.
• EPA for the win? - Plasma levels of the omega 3 fatty acid EPA in this case and past research had the largest association with less white matter lesions (EPA is more abundant in microglia vs. DHA)
• Fish Oil Dosage: The study used 1.65 grams of omega-3 per day, containing 975 mg of EPA and 675 mg of DHA (EPA dominant).
• Fish Oil Side Effects: supplementation at this dosage was well-tolerated, with no significant difference in adverse events between the omega-3 and placebo groups, making it a viable option for long-term use in older adults.

For those concerned about cognitive health, especially if there’s a genetic predisposition to Alzheimer’s, maintaining an adequate intake of omega-3s through diet or supplementation is generally recommended. The fish oil benefits for men and women likely extend beyond cardiovascular health, offering potential protection against the neurodegenerative changes associated with aging especially those at high risk for something like Alzheimer’s disease.

Iron may play a critical role in athletic performance

Iron is a key component of hemoglobin and myoglobin, proteins responsible for oxygen transport and storage in muscles, essential during aerobic exercise. When you’re exercising, especially in endurance sports, your muscles need a constant supply of oxygen to produce the energy they need to keep going. This process, known as aerobic respiration, is heavily dependent on iron (iron is what bind oxygen for transport in the body).

current recommendations for iron intake in men and premenopausal women do not take into account higher demands that attributable to exercise or sport.

There is past research that suggests athletes, specifically endurance athletes, may have iron needs that exceed the recommended intake by up to 70% (PMID: 38068803). However, other research shows that iron supplementation does not affect endurance performance if an iron deficiency is not present.

A recent study published in Nutrition (PMID: 39002373) highlights that iron deficiency is surprisingly common among athletes, particularly in female athletes, with nearly 20% affected (35% of total athletes including males). This deficiency can lead to reduced VO2 max, a key indicator of endurance (aerobic) performance.

The study looked at over 1100 athletes and showed that those with iron deficiency had significantly lower VO2 peak values, impacting their endurance capacity. Interestingly, the most iron-deficient athletes were females <19 years old.

findings:

• Iron deficiency without anemia still contributes to diminished athletic performance, especially in endurance sports.
• Nearly 35% of athletes, with higher rates in female athletes, suffer from iron deficiency, which was linked to lower VO2 peak levels.

Recommendations: Regular screening of iron levels, particularly in high-risk groups like female athletes, and ensuring adequate iron intake through diet or supplementation (under medical supervision, in this case) can help prevent performance declines.

For athletes (especially young ones), maintaining optimal iron levels is not just about avoiding anemia, it's also about maximizing your performance potential.

 Unlocking Better Sleep: The Tryptophan Amino Acid Connection

Tryptophan, an essential amino acid, is necessary in the synthesis of serotonin and melatonin, key regulators of sleep and circadian rhythms. A recent study published in Nutrients looked at the impact of dietary tryptophan intake on sleep quality among over 11,000 university students, a group notorious for erratic sleep patterns.

The study revealed that students consuming the highest amounts of tryptophan (over 800 mgs/day) experienced longer sleep and higher-quality sleep. Interestingly, even students who met the recommended daily intake of tryptophan (4-5 mg per kilogram of body weight) but were in the lowest quartile for intake, reported poorer sleep outcomes compared to their peers with higher intake levels.

Findings:

• tryptophan amino acid intake: Students in the highest quartile (over 804 mg/day) reported the best sleep outcomes.
• tryptophan as a sleep aid: Higher tryptophan intake was associated with reduced sleep onset latency and improved overall sleep quality, particularly in females.
• Dietary considerations: incorporating more tryptophan-rich foods may be a simple, yet effective strategy to enhance sleep quality.

This connection between tryptophan and sleep is not new but often overlooked. While many seek out flashier sleep aids, adjusting your diet to include more tryptophan might be a natural and effective solution. For those looking to improve their sleep, its important to remember diet is a key factor in sleep theory—what you eat can significantly impact how well you rest.

In this episode of Daily Value I cover recent research suggesting specific probiotic species may enhance the bioavailability of essential B-vitamins, offering insights into a [potentially] synergistic approach for optimizing metabolic and gut health.

Covered in the episode
- How some Lactobacillus species were shown to significantly increase the absorption of vitamins B1, B3, B5, and B12 in rodent models, despite these strains not being direct producers of B-vitamins.
- Proposed mechanisms, including alterations in gut pH and microbial cross-feeding dynamics, that facilitate enhanced vitamin uptake and influence overall nutrient absorption pathways.
- Contrary to the common belief that higher bacterial diversity is always favorable, the episode discusses how a targeted decrease in diversity may yield positive outcomes in terms of mucosal integrity and anti-inflammatory effects.

The findings discussed in this episode suggest potential therapeutic strategies for individuals with compromised gastrointestinal function or B-vitamin deficiencies. By combining high-quality B-vitamin supplementation with specific probiotic strains, there may be a pathway to more personalized and effective interventions. However, it’s crucial to consider individual variability, including baseline microbiota composition and genetic factors, when translating these findings to human populations.

Does magnesium supplementation reduce muscle soreness across various physical activities?

a review paper published in the Journal of Translational Medicine explored the effects of magnesium supplementation on muscle soreness across different physical activities.

Findings:
*Reduction in muscle soreness: magnesium significantly reduced muscle soreness and improves feelings of recovery in subjects.
*Performance enhancement: positive effects on performance metrics, including improved blood glucose levels and reduced muscle damage markers.
*Protective effects: regular magnesium intake showed a protective effect on muscle integrity during intense physical activities, such as professional cycling and team sports.

Dosage and timing: The review suggests that individuals engaged in intense physical activities should consider a magnesium dosage 10-20% higher than the Recommended Dietary Allowance (RDA), ideally taken in capsule form 2 hours before training.  Of note, information regarding the effectiveness of this specific dose and time is very scarce. It was also advised to maintain magnesium levels within the recommended range during the off-season.

Why magnesium is important for recovery: magnesium, an essential intracellular cation, is crucial for numerous biochemical reactions, including energy production, neuronal activity, cardiac function, and muscle contraction. Magnesium deficiency can impair physical performance and exacerbate muscle soreness post-exercise.

What magnesium is best for muscle recovery: tissue distribution data would suggest magnesium citrate is best for muscle recovery. However, long-term magnesium intake far outweighs acute tissue distribution after a single dose of magnesium.

What are magnesium-rich foods: 

Nuts and Seeds:
Almonds: 80 mg per ounce
Cashews: 74 mg per ounce
Pumpkin Seeds: 150 mg per ounce
Chia Seeds: 95 mg per ounce
Flaxseeds: 40 mg per tablespoon

Leafy Greens:
Spinach: 157 mg per cooked cup
Swiss Chard: 150 mg per cooked cup
Kale: 30 mg per cooked cup

 Zinc and the Common Cold: What You Need to Know

What does zinc do for the body? Zinc is an essential trace element vital for immune function, wound healing, and DNA synthesis. It supports over 300 enzymes and the proper function of immune cells like T-cells and macrophages. Zinc also aids in the production of antibodies that fight infections.

A recent review in the Cochrane Database of Systematic Reviews found that zinc supplements might not prevent colds, but taking zinc at the onset of symptoms can reduce the duration by about two days. This represents a 10-20% decrease in illness length, which is clinically significant.

Takeaways:
1. Zinc element in immunity: vital for immune cell function and enzyme activity, making it crucial in fighting infections.
2. Supplementation: Zinc gluconate and zinc acetate lozenges may effectively reduce cold duration if taken within 24 hours of cold symptoms.
3. Zinc supplementation reduces sick days of the common cold, but does not affect the odds of catching a cold or symptom severity.
4. Zinc deficiency: Can lead to significant health issues, emphasizing the need for adequate intake.

Safety note: Zinc supplements are generally well-tolerated, but high doses can cause nausea and gastrointestinal distress. Do not exceed the Tolerable Upper Intake Level of 40 mg/day regularly for adults without medical supervision.

What zinc should I take? Zinc gluconate and zinc acetate lozenges can be effective for boosting the immune system during colds. They can reduce the duration of symptoms if taken at the onset of illness. Consult your healthcare provider before starting any supplement regimen.

Zinc deficiency symptoms:
Weakened immune response
Hair loss
Diarrhea
Delayed wound healing
Loss of appetite
Impaired growth and development in children

Benefits of zinc:
Zinc Benefits For Men: Supports testosterone production, muscle growth, and overall immunity.

Zinc Benefits for Women: Crucial for reproductive health, skin health, and immune function.

Zinc-rich foods:
Red meat
Seafood (especially oysters)
Poultry
Beans
Nuts
Whole grains
Dairy products

 N-acetyl cysteine (NAC) shows promise for heart attack prevention

Heart attacks and strokes are a leading cause of death in developed countries - accounting for ~20% of all deaths in the U.S. Frequently, heart attacks and strokes are caused by blood clots (blood platelets that form when they are not needed, causing a narrowing/blockage of blood vessels) formed through arterial thrombosis. Current antiplatelet agents (e.g., aspirin) are effective but can increase major bleeding risk. As such, there is a growing need to prevent arterial thrombosis different from antiplatelet agents.

A recent study published in Arteriosclerosis, Thrombosis, and Vascular Biology investigated the potential of NAC as an agent to prevent arterial thrombosis. Utilizing both [cell-based] human blood models and mouse (in vitro) models, the research demonstrated that NAC significantly delayed and even prevented thrombus formation dose-dependently without increasing bleeding risks.

Findings:
*NAC treatment extended clot formation times by up to 3.7 times compared to controls in the human blood [cell] model.
*NAC entirely inhibited platelet aggregation and occlusive clot formation at higher doses than the above point in the cell model.
*A 400 mg/kg (via injection in rodents) dose of NAC in mice effectively prevented arterial occlusion post-injury.
*Lower doses (200 mg/kg - via injection in rodents) of NAC reduced clot stability, suggesting working as both an acute and preventative clotting therapy.

The study showed that NAC interferes with von Willebrand factor (a large protein crucial for blood clotting) activity. NAC acts against VWF rather than platelets to prevent clot formation. Thus, providing a safer alternative to traditional antiplatelet drugs that carry higher bleeding risks.

 Does green tea protect the aging brain better than coffee? In this episode of Daily Value, we look at the evidence behind green tea's impact on brain aging, focusing on cerebral white matter lesions, Alzheimer’s risk, and brain atrophy. Drawing on studies like Shibata et al.'s recent publication in Science of Food (PMID: 39774601), we discuss how a certain threshold of green tea, but not coffee is associated with less white matter lesions in aged individuals.

Discussion Points:

• MRI findings on green tea’s association with reduced white matter lesion progression in older adults consuming a specific amount of cups daily.
• Past research observing a 5% reduction in hippocampal atrophy rate in green tea consumers (amounts discussed in episode).
• Brewing techniques and supplement tips to optimize EGCG content and/or minimize caffeine content of tea.

In this episode of Daily Value, we look at the relationship between genetics, habitual caffeine intake, and cognitive performance, using insights from a recent study (PMID: 39648354) in the Journal of Psychopharmacology. Whether you’re a "fast" or "slow" caffeine metabolizer could significantly influence how caffeine impacts your brain.

Discussion Points:

• Gene-Caffeine Interactions: how variants in CYP1A2 and ADORA2A genes modulate caffeine metabolism and sensitivity, leading to differential effects on executive function and social cognition.
• Cognitive Domains: Why slow metabolizers consuming high caffeine outperform fast metabolizers in emotion recognition tasks, and why moderate caffeine enhances executive function in fast metabolizers.
• Practical Applications: Tailoring caffeine intake based on genetic predisposition to optimize focus, decision-making, and cognitive flexibility.

In this episode of Daily Value, we explore the recent findings on the role of B-group vitamins as potential prebiotic candidates and their effects on the human gut microbiome. The discussion is centered around some of the latest research, which highlights how these essential vitamins, traditionally known for their metabolic roles, are now being recognized for their ability to modulate the gut microbiome and how different bacterial species may also play key roles as B-vitamin Producers.

Discussion Points:
- The potential of B-group vitamins, such as riboflavin and niacin, to reach the colon and influence the diversity and functionality of the gut microbiome, particularly in enhancing the growth of beneficial bacteria like Faecalibacterium prausnitzii.

- The mechanisms by which B-group vitamins may exert prebiotic effects, including their impact on microbial cross-feeding and the production of short-chain fatty acids, crucial for maintaining gut health.

- The emerging evidence supporting the use of high-dose and colon-targeted formulations of B-group vitamins to optimize their prebiotic potential.

- This episode provides an overview of the current state of research on B-group vitamins and their implications for gut health.

In this episode of Daily Value, we look at how the roasting style of coffee—light versus regular—might influence body composition. Examining evidence from a recent randomized controlled trial published in Nutrients (PMID: 39275165). Could your choice of coffee enhance fat loss and muscle mass?

Discussion Points:

• Roasting and Polyphenols: How lightly roasted coffee, with higher chlorogenic acid content, outperformed regular roasts in reducing body fat (-1.4% vs. -1.0%) and increasing muscle mass (+0.8%).
• Mechanisms at Play: The role of chlorogenic acids and caffeine in body composition augmentation as outlined in mechanistic research.
• Practical Takeaways: Why choosing lightly roasted coffee and consuming it regularly may provide metabolic benefits over time (especially in sedentary/overweight populations).

In this episode of Daily Value, we look at how extra virgin olive oil and its polyphenols—including hydroxytyrosol—could impact your health and longevity. Referencing evidence from the Moli-Sani Study and other meta-analyses (PMID: 38704428), we uncover how these bioactives are suggested to reduce risks for cancer, cardiovascular disease, and all-cause mortality.

Discussion Points:

• Bioactive Compounds: How hydroxytyrosol prevents LDL oxidation and reduces inflammation, key mechanisms for cardiovascular protection.
• Landmark Studies: The Moli-Sani cohort found a 28% reduction in cancer deaths with a certain threshold of olive oil, while meta-analyses confirm a 16% lower cardiovascular risk with similar amounts of olive oil.
• Practical Takeaways: Why cold-pressed extra virgin olive oil is essential for these benefits and how just 3 tablespoons daily could support health outcomes.

In this episode of Daily Value, we explore the potential of omega-3 fatty acids, particularly EPA and DHA, as an adjunctive therapy for reducing anxiety symptoms. A recent meta-analysis (PMID: 38890670) reviewed 23 randomized controlled trials involving over 2,100 participants, revealing that a certain amount of omega-3s per day can significantly reduce anxiety symptoms, especially when combined with traditional treatments like antidepressants.

Talking points:

• Anxiety disorders: what are they and how many people have them?
• Fish oil benefits for anxiety disorders
• Effective dosage of omega-3 fatty acids for reducing anxiety symptoms.
• Mechanisms of action: Omega-3s may reduce anxiety through 4 proposed mechanisms.

In this episode of Daily Value, we look at how paternal alcohol consumption before conception could influence offspring health, longevity, and even accelerate aging. Referencing studies from Andrology (PMID: 38044754) and Aging and Disease (PMID: 39122451), we examine how sperm RNA modifications and mitochondrial dysfunction may persist long after alcohol cessation—potentially programming offspring for metabolic disorders, reduced NAD+ levels, and faster cellular aging.

Discussion Points:

• Sperm Epigenetics: what rodent data tells us baout alcohol exposure altering small RNAs in sperm, disrupting gene regulation in the developing embryo.
• Mitochondrial Dysfunction: newer rodent data showing lower SIRT1/SIRT3 levels, and lower NAD+ in offspring whose parents were exposed to alcohol.
• Practical Takeaways: How long should alcohol cessation be before conception could help restore sperm quality and reduce the risk of accelerated aging in children for people who drink regularly.
