Alpha GPC + Uridine: Can This Duo Build Better Synapses?
Alpha GPC + Uridine Monophosphate
Support cholinergic signaling and phospholipid/synapse building to aid memory, focus, and cognitive resilience.
- •The duo is a plausible dual-pathway stack (choline + uridine) with animal and mechanistic support
- •Direct Alpha GPC + UMP human data are lacking, so synergy is theoretical, not proven.

Ashwagandha + Rhodiola: Calm Energy or Just Hype?
Ashwagandha + Rhodiola
Stress resilience with steady daytime energy and calmer sleep
Dual-core, theoretical synergy: good rationale, solid solo data, but no head-to-head Ashwagandha+Rhodiola trials yet.

Brain Fuel That Slows Cognitive Decline
Vitamin B Complex + Omega-3
Support brain aging and cognitive function by lowering homocysteine (via B vitamins) and enriching/repairing brain cell membranes and calming inflammation (via omega-3), with suggestive human data that the two work better when both statuses are adequate.
- •Promising but unproven synergy for brain aging
- •No proven synergy for heart events. Best results appear when BOTH omega-3 and B-vitamin status are good. [1][2][3]

Memory Stack With Real Clinical Data
Bacopa Monnieri + Citicoline
Sharper memory encoding plus steadier attention/mental clarity by boosting acetylcholine from two angles and supporting neuron membranes while dialing down stress reactivity.
- •Dual-core, theoretical synergy: both work on their own
- •Together looks additive with plausible complementarity, but no direct human A+B head-to-head proof yet.

Heart Energy Amplified: Cellular Power Duo
CoQ10 + Fish Oil
- •Heart and vascular support by pairing mitochondrial energy/antioxidant support (CoQ10) with lipid/inflammation support (EPA/DHA from fish oil)
- •Possible absorption help for CoQ10 when taken with fats.
- •Evidence suggests mostly additive benefits
- •True synergy is unproven, with a plausible absorption assist from taking CoQ10 alongside fats like fish oil. [1][2][3]

Power + Endurance: The Proven Combo
Creatine + Beta-Alanine
Improve high-intensity exercise performance (repeated sprints, intervals lasting ~30 s to 4 min), training volume, and possibly body composition when combined with structured training. [1][2][3]
- •Additive dual-pathway benefits for intense, repeated efforts
- •No proven absorption synergy or extra boost for 1-rep max. [1][2]

2000% Absorption Boost: The Bioavailability Hack
Curcumin + Piperine
Boost curcumin's absorption and staying power in the body so its anti-inflammatory actions translate into real-world benefits (e.g., joint comfort, metabolic and liver markers). [1][2][9]
Proven absorption synergy (big) + plausible anti-inflammatory teamwork (early), but head-to-head clinical superiority over curcumin alone is not yet proven. [1][2][3][4][9][10][11]

Calm Focus Unlocked: Kill The Jitters
L-Theanine + Caffeine
Calm, focused alertness for short-term cognitive tasks while reducing caffeine's jitters and blood-pressure reactivity.
- •Real but modest, short-term benefits with a "gas pedal + steering" effect
- •Best for focused tasks, not all-day stimulation.

Lion’s Mane + Bacopa: Smart Memory Duo or Just Hype?
Lion's Mane + Bacopa
Support memory, learning, and long-term brain plasticity (neurogenesis/BDNF) while easing stress-related interference with recall.
The combo is a theoretical dual-pathway stack (neurotrophic + cholinergic), but there are no direct head-to-head studies proving synergy.

The Activation Key: Why D3 Fails Alone
Magnesium + D3
Optimize vitamin D activation/status and calcium balance to support bone strength and overall metabolic health (while avoiding vitamin D "not working" because of low magnesium). [1][3][7]
- •Cofactor-enabled synergy: magnesium flips vitamin D's "on" switch, and RCTs show Mag+D raises 25(OH)D more than vitamin D alone
- •Clinical outcomes beyond vitamin D status are mixed. [1][3]

Sleep & Recovery: The Athletic Triangle
Magnesium + Zinc + Vitamin B6
Night-time recovery and sleep support in active people, with possible benefits for stress/PMS when magnesium is paired with vitamin B6.
- •Magnesium + B6 shows small, condition-specific synergy
- •Adding zinc hasn't proven extra benefits and can compete with magnesium at high doses.

NAC + Glycine (GlyNAC): Rebuilding Glutathione Together
NAC + Glycine
Restore the body's glutathione system to lower oxidative stress and improve mitochondrial function (with spillover benefits to metabolic, vascular, strength and cognition markers in older or stressed adults). [1][2][3][4][5]
Promising dual-precursor combo that raises/normalizes glutathione and improves multiple markers in certain human trials—but true synergy (A+B vs A or B) isn't yet proven. [1][2]

Protected Brain Fuel: Prevent The Damage
Omega-3 + Vitamin E
Reduce inflammation and oxidative stress while protecting fragile omega-3 fats from oxidation to support vascular and metabolic health.
- •Protective + dual-pathway combo with promising but not definitive synergy
- •Best for lowering inflammation/oxidative stress markers, not proven to outperform omega-3 alone on hard outcomes.

Quercetin + Bromelain + C: Allergy & Airways Combo?
Quercetin + Bromelain + Vitamin C
Reduce upper-airway allergy symptoms and swelling (sneezing, runny nose, sinus pressure) and provide adjunct immune support during respiratory infections.
- •Theory-supported, partially studied combo
- •Helpful for some, but true "A+B>C than A or B alone" synergy is unproven.

Triple Absorption Power: Fix Deficiency Faster
Vitamin C + Iron
Improve non-heme iron absorption from meals and oral supplements to correct iron deficiency and anemia faster and with fewer obstacles.
Proven absorption synergy for non-heme iron, but no added clinical benefit over iron alone in modern RCTs—use vitamin C when meals or inhibitors are an issue, not as a mandatory add-on. [1][6][7]

Strong Bones, Safe Arteries: The Traffic Cop
Vitamin D + Calcium + Vitamin K2
Build and maintain strong bones while keeping calcium out of arteries (bone-first, artery-safe calcium handling).
- •Some orchestrated logic, mixed evidence: D+Calcium helps modestly
- •Adding K2 improves calcium "traffic control," but human bone benefits beyond D+Calcium are small or site-limited so far. [1][2][3]

The Immune Vision Duo: Unlock What's Stuck
Zinc + Vitamin A
Help vitamin A do its jobs (vision, skin and mucous barrier, and immune signaling) by making sure the body can move, convert, and use vitamin A properly—especially when zinc is low. In deficient settings, the duo has reduced persistent diarrhea and improved night vision more than either alone.
Context-dependent synergy: proven in deficiency settings (especially for persistent diarrhea and pregnancy night blindness), but additive or null elsewhere.

Tocotrienols
"The stealthier cousins of vitamin E—built with springy tails that move differently in cell membranes and behave differently in your body."
If tocopherol is a sturdy hiking boot, tocotrienol is a flexible running shoe—the same mission (protect the trail) but built to move differently through the terrain.

Zinc
Zinc: The Metal That Had to Become Vapor—and Then Became Medicine

Alpha‑GPC (choline alphoscerate)
vsCDP‑Choline (Citicoline)
For daily focus and memory, pick Citicoline (250–500 mg/day). For a one-off workout power boost, Alpha-GPC (≈600 mg pre-session) has limited acute data—but weigh a cohort signal of higher long-term stroke risk if used chronically, especially in older adults.

Apigenin (isolated flavone)
vsGerman Chamomile Extract (Matricaria recutita)

Astaxanthin
vsLutein (with zeaxanthin)
For AMD risk/progression, choose lutein with zeaxanthin (AREDS2-level dosing). For screen-related eye strain without AMD, astaxanthin may help symptoms short term; it's not a substitute for AREDS2 [2,8,14–16,18].

Berberine (dietary supplement)
vsMetformin (prescription biguanide)
For most people needing reliable glucose lowering and long-term outcome data, choose metformin. Consider berberine if you can't take metformin and want a modest, supplement-based metabolic aid from a vetted brand, with attention to interactions and pregnancy avoidance. [1][3][8]

Ceylon cinnamon (Cinnamomum verum)
vsCassia cinnamon (C. cassia, C. burmannii, C. loureiroi)

Collagen Peptides (Hydrolyzed)
vsBone Broth (Traditional/Commercial)

Current (Actual) Body Weight method
vsGoal/Ideal/Adjusted Body Weight method

Creatine Monohydrate (CM)
vsCreatine Hydrochloride (Cr-HCl)

L‑Theanine
vsGABA (gamma‑aminobutyric acid)

KSM-66 Ashwagandha (Ixoreal)
vsSensoril Ashwagandha (Natreon)

Liposomal Vitamin C (liposome-encapsulated ascorbic acid)
vsStandard Vitamin C (ascorbic acid; tablets/capsules)

Magnesium glycinate (magnesium bisglycinate)
vsMagnesium citrate

Magnesium L‑Threonate (Magtein)
vsMagnesium Glycinate (bisglycinate/diglycinate)

Marine collagen peptides (fish‑derived)
vsBovine collagen peptides (hide‑derived)

L‑methylfolate (5‑MTHF)
vsFolic acid

NAD+ (direct NAD+ therapy)
vsNMN (nicotinamide mononucleotide)

β‑Nicotinamide Mononucleotide (NMN)
vsNicotinamide Riboside (NR, as NR chloride)
If you want the most standardized, widely available NAD+ booster with strong human data on NAD+ raising and safety, choose NR. If you're working with a clinician or enrolling in NMN trials, pharmaceutical-grade NMN can also raise NAD+, but retail NMN faces regulatory and quality issues. [1][2][5][8][11][13][14][16]

Fish Oil (EPA+DHA from fish oil)
vsKrill Oil (Antarctic krill oil)
For most people seeking proven heart benefits or triglyceride lowering, choose fish oil (or prescription EPA) because outcomes data are strongest. Pick krill oil if you prefer smaller caps and potentially gentler GI feel, knowing EPA+DHA per capsule is usually lower. [4][6][1]

Probiotics (live microbes)
vsPrebiotics (selective substrates)

Seed Oils (canola, soybean, sunflower; high‑oleic variants)
vsAnimal Fats (ghee/clarified butter, beef tallow)
For overall health, pick seed oils—prefer high-oleic (or olive/avocado)—for most day-to-day cooking; they support better cardiometabolic risk profiles. Use ghee or tallow mainly for flavor or occasional very-high-heat tasks, and keep portions modest to limit saturated fat. [1][2][3][12][19]

Theobromine
vsTeaCrine (theacrine)
For smooth, long-lasting, low-stimulation energy, choose TeaCrine 100–200 mg in the morning; it shows sustained subjective energy without HR/BP spikes. Pick theobromine only if you want the mildest CNS effect and lowest "buzz," but expect little measurable energizing benefit. [1][2][7]

Tirzepatide (Zepbound/Mounjaro)
vsSemaglutide (Wegovy/Ozempic/Rybelsus)

TMG (betaine anhydrous; trimethylglycine)
vsBetaine HCl (betaine hydrochloride)

Tongkat Ali (Eurycoma longifolia)
vsFadogia agrestis

Trans‑Resveratrol
vsPterostilbene
For longevity-focused use, pick trans-resveratrol if you want the better-studied option with modest, low-certainty benefits on human risk markers; choose pterostilbene only if you prioritize dosing convenience and can monitor LDL cholesterol. Neither has proven human lifespan extension. [8][4].

Turmeric (whole root/powder, full‑spectrum)
vsCurcumin (standardized curcuminoids)

Uridine 5'-Monophosphate (UMP)
vsTriacetyluridine (Uridine Triacetate, TAU)

Vitamin D3 (cholecalciferol)
vsVitamin D2 (ergocalciferol)

Whey protein (concentrate/isolate/hydrolysate)
vsPlant protein (pea/soy/rice blends)
Pick whey if you want the most leucine and lean-mass support per scoop and you tolerate dairy; pick plant protein if you're vegan/dairy-sensitive—just use a blend or slightly larger dose to match leucine.

Curcumin (bioavailable): 500–1,000 mg/day + piperine; 2–4 wks. [1] [4]

Best for liver health
Silybin phytosome (milk thistle) 160–240 mg, 2×/day. [2][4]

Best for mood (mild depression or anxiety)
Silexan (oral lavender) 80–160 mg/day – best for anxiety-driven low mood [1][2]

Best for post-workout recovery

Best for Skin health (clear, hydrated, youthful-looking skin)
Lactoferrin 200–300 mg/day – fast acne/sebum control [1][2]

Best for brain fog
L-theanine 100–200 mg + caffeine 50–160 mg (fast focus) [1][2]

Best for energy
Caffeine 50–200 mg + L-theanine 100–200 mg 30–60 min pre-task [5][6]

Best for Fatty Liver (NAFLD/MASLD and NASH)
Omega-3s (EPA/DHA)

Best for focus
L-theanine (100–200 mg) + caffeine (40–160 mg)

Best for GLP-1 support
Whey protein shot 15–30 g before meals [1][2]

Best for gut health

Best for longevity
Selenium 200 mcg + CoQ10 200 mg daily (4 yrs) — mortality signal [2]

Best for menopause
ERr 731 (4 mg/day) — best nonhormonal VMS relief in RCTs. [2][5]

Best for muscle growth
Creatine monohydrate: 3–5 g daily

Best for neuropathy
Alpha-lipoic acid 600 mg/day (fastest for DPN symptoms) [2][4]

Best for PCOS
Inositol 40:1 (2 g MI + 50 mg DCI, twice daily) — best for cycles/ovulation [1][2]

Best for sleep
Saffron extract: 20–30 mg nightly (2–4 weeks). [14][16]

Best for stress relief
Silexan lavender oil: 80–160 mg daily. Strongest overall RCT support. [1][5]

Best for testosterone
Tongkat ali: 200–400 mg/day; best evidence for total T, 2–8 weeks. [1] [5]
