6 Key Concepts
Foundational Supplements
These are supplements designed to provide an insurance policy against dietary deficiencies, ensuring basic levels of mental and physical health. They often include vitamins, minerals, digestive enzymes, adaptogens, and prebiotics/probiotics.
Adaptogens
A broadly defined category of micronutrients, herbs, or mushrooms thought to improve the body and brain's ability to buffer against various stressors, such as reducing cortisol levels or enhancing cognitive function.
Gut Microbiome
The collection of trillions of microbacteria living in the body, primarily in mucus membrane-lined tissues like the gut. A diverse microbiome is advantageous for immune system function, hormone function, and the gut-brain axis, impacting mood and motivation.
Placebo Effects
Real effects where our belief or expectation about a treatment influences the outcome. These can be very real and can dovetail with discussions about dependency, where an emotional or cognitive association with taking something allows for a desired effect.
Floor and Ceiling Effects
These describe how the efficacy of a supplement can depend on an individual's baseline levels. People starting with very low (floor) levels of a hormone or function may experience dramatic improvements from a supplement, while those already at optimal or high (ceiling) levels may see little to no additional benefit.
Single-Ingredient Formulations
The practice of taking supplements that contain only one active ingredient, rather than multiple. This approach provides greater control to identify minimal effective doses, rule out ineffective or detrimental compounds, and manage costs effectively.
9 Questions Answered
The hierarchy starts with behavioral tools (actions taken or avoided), followed by nutrition, then supplementation, and finally, prescription drugs. Each layer builds upon the previous one, with behaviors forming the bedrock.
A vitamin and mineral supplement makes sense for individuals who are extremely physically and/or mentally active, practice intermittent fasting or caloric restriction, or are unable to regularly ingest enough variety of foods to cover their vitamin and mineral needs from diet alone.
Ingesting four servings a day of low-sugar fermented foods (like sauerkraut, kimchi, Greek yogurt, kombucha, kefir, natto) has been shown to greatly improve gut microbiome function, enhance the immune system, and reduce inflammation.
In most cases, no, there isn't a physical dependence on sleep supplements like magnesium threonate, theanine, or apigenin. People often find they can still sleep fine even after missing a night of supplementation, though the depth and duration of sleep might not be as good.
The best way to augment growth hormone is to get quality deep sleep, especially in the first three to four hours of the night, and to avoid caloric intake in the two hours preceding sleep.
Adequate caloric intake from quality foods, which allows insulin levels to be a bit higher (not excessively), can inhibit sex hormone binding globulin (SHBG). Lower SHBG means more free testosterone, which is the more active form.
The best way is a good night's sleep of sufficient duration, as sleep is crucial for neural connection remodeling and learning consolidation. Additionally, maintaining sufficient nutrition (avoiding extreme hunger or over-satiation) is important.
Yes, ingesting one to three grams of EPA (eicosapentaenoic acid) per day, often from fish oil, can be beneficial for cognitive ability, focus, metabolic function, cardiovascular function, and can help offset depression and improve mood.
While some evidence suggests omega-3 fatty acids can be beneficial for developing brains (obtainable from food or supplements), melatonin supplementation in children is generally not recommended due to potential harm and already elevated chronic levels in kids. Hormone-augmenting supplements should be avoided until at least after puberty and likely into the early 20s, unless specifically recommended by a physician.
38 Actionable Insights
1. Consult Physician for Protocols
Always consult a trusted board-certified physician before adding or subtracting any behavioral, nutritional, supplementation, or prescription drug protocols to ensure safety and appropriateness for your individual health.
2. Prioritize Behavioral Tools
Form the foundation of mental health, physical health, and performance by implementing specific actions and avoiding others, such as viewing morning sunlight, exercising, and avoiding late-night bright light.
3. Prioritize Quality Nutrition
Establish nutrition as the second foundational layer, as no amount of supplementation can compensate for poor nutrition long-term. Aim for 75-80% or more of your food intake from non-processed or minimally processed sources.
4. Systematic Supplement Testing
When exploring targeted supplements, test single-ingredient formulations for about a week each, without changing other protocols, to identify minimal effective doses and rule out ineffective or detrimental compounds. This helps isolate variables and understand individual impact.
5. Test Hormonal Supplements with Blood Work
Before and after about four to eight weeks of taking any hormone-modulating supplement, get blood tests to objectively evaluate its effectiveness and ensure it’s not causing unwanted negative effects.
6. Start Supplements at Minimal Dose
Begin any new supplement regimen with the minimal effective dose and gradually build up protocols over time, playing the long game to find what works best for you in both the immediate and long term.
7. Support Gut Microbiome
Ingest four servings a day of low-sugar fermented foods (e.g., refrigerated sauerkraut, kimchi, Greek yogurt, kombucha, kefir, natto, pickles with brine) to greatly improve gut microbiome function, enhance the immune system, and reduce inflammation.
8. Consider Foundational Multi-Supplements
For comprehensive coverage of vitamins, minerals, digestive enzymes, adaptogens, and probiotics/prebiotics, consider a broad-spectrum, multi-ingredient foundational supplement, especially if your budget allows for about $100 or more per month.
9. Prioritize Omega-3s for Budget
If on a limited supplement budget, prioritize a high-quality omega-3 fatty acid fish oil, aiming for 1-3 grams of EPA per day, to support mood, metabolic, cardiovascular, cognitive function, and focus.
10. View Morning Sunlight
View morning sunlight to increase cortisol levels early in the day, which is crucial for focus, alertness, immune function, and ensuring lower cortisol levels at night for optimal growth hormone and testosterone release.
11. Avoid Late-Night Bright Light
Avoid bright light exposure to your eyes between 10 p.m. and 4 a.m. to enhance mental health, physical health, and performance by supporting healthy sleep architecture.
12. Limit Afternoon Caffeine
Limit or eliminate caffeine intake after 2 p.m. (or even noon) to prevent disruption of sleep architecture, which can diminish mental health, physical health, and performance the following day.
13. Avoid Eating Before Bedtime
Avoid food intake within two hours prior to bedtime to facilitate growth hormone release during sleep and improve your ability to fall and stay asleep, but ensure you’re not so hungry that it prevents sleep.
14. Engage in Strenuous Exercise
Incorporate strenuous exercise, including both cardiovascular and relatively short (under an hour) bouts of intense resistance training a few times per week, to dramatically alter and improve hormone profiles.
15. Take Vitamin/Mineral Supplements with Food
Ingest vitamin and mineral supplements with food, ideally early in the day, to prevent stomach upset (especially from B vitamins) and optimize absorption.
16. Avoid Excessive Probiotics/Prebiotics
If taking probiotic/prebiotic supplements, ensure they contain low enough levels to avoid potential issues like brain fog, which can be associated with excessive intake.
17. Use Magnesium for Sleep
Consider magnesium threonate or bisglycinate to shorten the transition time into sleep and deepen sleep, as they readily cross the blood-brain barrier and induce mild drowsiness.
18. Use Apigenin for Sleep
Consider apigenin, a chamomile derivative, to lower anxiety prior to sleep, helping to reduce rumination and facilitate falling asleep.
19. Use Myo-Inositol for Waking
If you wake up in the middle of the night and struggle to fall back asleep, consider taking 900 milligrams of myo-inositol to help shorten the time it takes to return to sleep.
20. Avoid Theanine with Vivid Dreams
If you experience excessively vivid dreams that cause you to wake up jolted or anxious, avoid theanine supplementation (typically 100-400mg) as it can intensify dreams for some individuals.
21. Exercise Caution with Melatonin
Use melatonin only occasionally for specific purposes like jet lag, as it primarily induces sleepiness but doesn’t maintain sleep, can impact other hormone systems, and often has inconsistent dosages in supplements.
22. Cycle Sleep Supplements
Every two weeks or so, or perhaps every month, take one night off completely from all your sleep supplements or leave out one sleep supplement, ideally on a non-critical night, to assess any real or placebo-based dependency.
23. Consider Shilajit for Hormones
Explore shilajit, containing fulvic acid, to augment multiple hormone systems, potentially increasing FSH, testosterone, estrogen, and libido, but cycle its use (e.g., 8 weeks on, 2 weeks off) and adhere to recommended dosages.
24. Consider Ashwagandha for Cortisol
Use ashwagandha to reduce cortisol levels, which can indirectly lead to increased testosterone; however, avoid taking high dosages for more than two weeks at a time.
25. Consider Maca Root for Libido
If experiencing lowered libido, consider maca root, which can increase libido in both men and women, including those on SSRIs, by augmenting dopamine and upstream hormone pathways.
26. Cycle Fadogia Agrestis
If using Fadogia Agrestis (600mg/day) to potentially increase libido, sperm production, testosterone, or estrogen, cycle its use (e.g., 8 weeks on, 2 weeks off or 12 weeks on, 1 month off) and never exceed recommended dosages due to potential toxicity at high levels.
27. Consider Tongkat Ali
Explore Tongkat Ali (200-600mg/day) to potentially increase libido and free testosterone by reducing sex hormone binding globulin; start with a minimum dose, scale by body size, and allow 8-12 weeks for effects to manifest.
28. Consider L-Carnitine for Fertility
For fertility support, consider orally ingested L-Carnitine to improve sperm motility and quality, and egg quality, noting that injectable L-Carnitine requires a prescription.
29. Use Caffeine for Focus
Ingest caffeine (1-3mg/kg body weight, 30 minutes before activity) for enhanced alertness and focus, noting that pill form can be more potent than coffee/tea, but avoid late afternoon intake and exercise caution if prone to anxiety.
30. Avoid Smoked Yerba Mate
If consuming Yerba Mate for caffeine or other purposes, always choose non-smoked varieties, as smoked versions are carcinogenic.
31. Use Alpha GPC for Focus
Take Alpha GPC (300-600mg) to enhance focus by augmenting acetylcholine pathways, providing a non-stimulant increase in cognitive attention lasting 4-6 hours.
32. Use L-Tyrosine for Focus
Consider L-Tyrosine (500-1000mg) as a dopamine precursor to increase focus without the jittery feeling of stimulants, but be aware that some individuals may experience a ‘crash’ afterward.
33. Exercise Caution with Alpha Yohimbine
Be very careful when considering alpha yohimbine (rauwolscine) as a stimulant for alertness and fat loss, as it is potent and can cause significant anxiety in some individuals.
34. Separate Stimulant & Neuromodulator Supplements
When exploring cognitive enhancers, try stimulant-based supplements (e.g., caffeine) and neuromodulator-based supplements (e.g., Alpha GPC, L-Tyrosine) separately before combining them, to understand their distinct effects on alertness versus focus.
35. Avoid Hormonal Supplements in Youth
Strongly avoid hormone augmentation supplements for individuals under 20-22 years old, unless specifically recommended and closely monitored by a board-certified physician, as the body and brain are still developing.
36. Adjust Supplements for Menstrual Cycle
Women should be prepared to adjust dosages or cease certain supplements (e.g., Shilajit, Tongkat Ali, Maca) at different phases of their menstrual cycle, as hormonal shifts can alter their effects and comfort levels.
37. Meet Daily Protein Needs
Aim for approximately one gram of protein per pound of body weight per day, primarily from high-quality sources, to support protein synthesis, recovery from exercise, and muscle building.
38. Get Enough Sleep for Cognition
Prioritize good quality sleep of sufficient duration as the most effective cognitive enhancer, as it is during sleep that neural connections remodel and learning is consolidated.

2 Protocols
Systematic Supplement Testing for Sleep
Andrew Huberman- Identify specific sleep issues (e.g., trouble falling asleep, staying asleep, or feeling alert during the day).
- Address behavioral and nutritional factors first (e.g., avoid caffeine after 2 PM, avoid food 2 hours before bed).
- If issues persist, select a single-ingredient supplement known to address your specific sleep issue (e.g., magnesium threonate for falling asleep).
- Take the chosen supplement for approximately one week, observing its effects on sleep latency and quality, while keeping other variables constant.
- If no negative effects, try a different single-ingredient supplement for another week, or combine the first two if they both showed benefit.
- Evaluate which individual supplements or combinations are most effective for your specific sleep goals.
Fadogia Agrestis Supplementation Protocol
Andrew Huberman- Take Fadogia Agrestis at a dosage of 600 milligrams per day.
- Cycle the supplement: 8 weeks on, followed by 2 weeks off, or 12 weeks on, followed by 1 month off.
- Monitor hormone levels with blood tests before starting and after 4-8 weeks of use to evaluate efficacy and rule out negative effects.
- Do not exceed recommended dosages, as high levels can be toxic to testicular cells.
