Supplements

Use modafinil only if it has already been prescribed by a board-certified physician, and pay attention to when you take it relative to studying or other learning. Because its effects last for hours, the timing can change whether it supports focus during the learning session itself or carries over afterward, which affects both performance and sleep.

Maca is typically taken as 2–3 g per day in powder or capsule form, usually earlier in the day because it can feel mildly stimulating and may disrupt sleep if taken late. It’s used mainly to improve libido, with reports of benefit in women, men, and people with SSRI-related sexual side effects, possibly through dopamine and upstream hormone pathways.

A daily collagen powder routine, typically around 15 g per day and sometimes increased toward 25–30 g, taken consistently for at least a couple of weeks. It’s used mainly to support skin elasticity and appearance, with reported benefits for wrinkles, sagging, and overall skin, hair, and nail health.

A chamomile extract supplement used as a bedtime sleep aid. It’s taken to help with falling asleep, staying asleep, and waking up feeling more refreshed, likely by promoting a calmer pre-sleep state.

An amino acid used as a serotonin precursor, sometimes taken in the evening or before a gratitude practice to nudge serotonin upward. The intended effect is to support relaxation or sleep via serotonin/melatonin pathways, though some people report disrupted sleep architecture or a brief sleep followed by waking and poor rest.

Skip THC as a sleep aid, especially at night, because it may help you fall asleep faster but tends to suppress REM sleep and disrupt normal sleep architecture. Regular use can build tolerance, and stopping can trigger REM rebound with vivid dreams plus withdrawal-related insomnia.

A pre-workout citrulline supplement used when you want performance support without caffeine, especially for evening training. It’s taken to raise arginine and nitric oxide, which can improve vasodilation and workout blood flow, with some discussion of possible growth-hormone support via the arginine pathway. Because it can lower blood pressure, it’s best used cautiously by people prone to hypotension.

A magnesium citrate supplement protocol aimed at recovery and tissue remodeling, with one suggested dose around 6 mg per kg of body weight. Citrate was highlighted as the form with the strongest evidence in this context, likely because magnesium supports muscle function, repair processes, and overall recovery after training or stress.

Supplement iron only when labs show deficiency, rather than taking it blindly. The protocol is to check blood levels first and aim for the appropriate range, since too little iron can cause anemia while too much can be toxic. This makes supplementation a targeted fix for low iron status instead of a routine daily add-on.

A sulforaphane supplement used to support phase II liver detoxification. The protocol mentioned was about 50 mg per day, with a caution that commercial products vary widely in potency, so lower-dose formulations may be preferable. The intended benefit is to help the body’s detox pathways work more effectively without overdoing the dose.

A clinical ketamine protocol used alongside psychotherapy to help blunt the emotional charge of traumatic memories, sometimes even very soon after the trauma. The idea is to create enough distance from the experience that it can be processed without the usual intense reactivity, which may make therapy more effective for some people.

A cautious testosterone replacement approach used in women with very low levels, especially when low libido and difficulty building muscle are present. Dosing is kept within the physiologic female range rather than pushed into male-range levels, with some clinicians also using it off-label for hypoactive sexual desire disorder and for bone or muscle support. The goal is to restore symptoms while avoiding supraphysiologic exposure.

Use vitamin B12 supplementation when you’re vegan or vegetarian, since dietary intake is often insufficient. Oral B12 is usually effective, but people with autoimmune pernicious anemia or other absorption/transport problems may need high-dose B12 and sometimes additional B1 support. The goal is to prevent deficiency-related neurologic and blood issues by replacing a nutrient that’s otherwise hard to obtain from plant-based diets.

A standard pharmacologic approach for lowering ApoB and LDL cholesterol when diet alone is not enough. Statins work by inhibiting cholesterol synthesis and upregulating hepatic LDL receptors, which helps clear LDL from the bloodstream. The main benefit is a substantial reduction in cardiovascular risk, including heart attacks and strokes.

Vitamin B6 is used as a prolactin-lowering supplement, often included in testosterone-support stacks. The idea is that reducing prolactin may help shift the dopamine balance upward, which is why it’s sometimes taken for hormonal support or after major stressors/events.

Astaxanthin is a carotenoid supplement commonly discussed alongside lutein and zeaxanthin for eye health. The recurring use case is supporting or maintaining vision, with the appeal being that it appears unlikely to be dangerous based on current evidence, though the evidence base is still limited.

An over-the-counter acetylcholine-boosting compound used to create a short-lived window of enhanced plasticity, often paired with exercise. It works by increasing cholinergic signaling, which can also support downstream dopamine activity in brain regions tied to learning and focus.

A growth-hormone–promoting peptide used in small doses, typically 200–400 micrograms taken before bed. It’s usually cycled 3–5 nights per week rather than used every day to reduce desensitization. The appeal is to support natural nighttime growth-hormone release and recovery while preserving responsiveness over time.

A growth hormone-releasing peptide used at bedtime, typically kept at 100 mcg or less. The protocol is favored for being relatively “clean,” with reports of improved sleep and a subtle leaning-out effect while minimizing side effects at low doses.

Use Ritalin only if it has already been prescribed by a board-certified physician, and pay attention to when you take it relative to studying or learning. The key protocol is to match dosing to the drug’s duration of action and whether you want the effect to support learning before, during, or after the material, so the cognitive boost lines up with the task instead of wearing off at the wrong time.

A boron supplement protocol used to help regulate sex hormone-binding globulin, with the effect described as mostly acute. A common approach is 3 to 6 mg once or twice daily, and some suggest cycling it rather than taking it continuously. The appeal is its potential to shift SHBG and thereby influence free hormone availability.

Estrogen therapy for women in perimenopause or after menopause, typically discussed with a clinician and started early when appropriate. The common protocol emphasis is timing: benefits appear strongest when begun around ages 50–59 or within about 10 years of menopause, and it is often used to relieve hot flashes. It may also help preserve cognition and support skin, with possible cardiovascular benefit when started in that earlier window.

Serotonin-boosting sleep supplements such as tryptophan and 5-HTP are generally approached with caution or avoided, especially when they seem to worsen sleep. The concern is that increasing serotonin can alter normal REM and slow-wave sleep timing, leading to falling asleep deeply at first but waking a few hours later or otherwise having more fragmented sleep.

Human growth hormone is sometimes added experimentally during ovarian stimulation for about two weeks in selected IVF patients. The goal is to improve egg maturity and embryo development, likely by enhancing ovarian response in the right patient.

Supplementing iodine to support thyroid hormone production, especially for some people with hypothyroidism. It can come from kelp, seaweed, or kelp tablets, but the key caution is to avoid excess and talk with a doctor first because too much iodine can be harmful.

Chromium is a trace mineral commonly included in glucose-lowering supplement blends. It’s typically taken as part of a daily supplement routine to support blood sugar control, with a modest effect on glucose metabolism rather than a dramatic standalone impact.

A ginkgo biloba supplement used mainly for tinnitus, with the cited evidence coming from double-blinded studies lasting about 1 to 6 months. The idea is that it may help some age-related tinnitus cases, especially when tinnitus overlaps with cognitive decline, though the overall evidence is limited.

Use a fiber supplement when whole-food intake is falling short, especially if you’re only getting about half of the recommended daily fiber. The idea is to use it as a practical backstop rather than a replacement for fiber-rich foods, helping bring total intake closer to target and support regularity and overall gut health.

A mitochondrial-targeted supplement typically taken daily, often in older adults or people looking to preserve physical function. Randomized controlled trials suggest it can improve muscle endurance, strength, and lean mass over about 8 weeks, likely by supporting mitophagy and healthier cellular energy production.

A prescription wakefulness medication used with physician guidance, especially to choose the best time of day to take it. The practical point is timing: taking it appropriately can support alertness while aligning its stimulant-like effects with the day, since it enhances dopaminergic signaling similarly to other ADHD/wakefulness agents.
