Deep dives into supplement research, ingredient analysis, and the science behind what works. Written by the Biorank Research Team.
KSM-66 vs Sensoril, cortisol reduction data, testosterone claims reality-checked, and anxiety evidence. A comprehensive look at what ashwagandha can and cannot do.
Whey vs casein vs plant protein -- the differences are smaller than you think. What actually matters for muscle growth: total daily intake, leucine thresholds, and why timing is overrated.
NSF vs USP vs Informed Sport vs IFOS -- what each certification actually tests. Plus the products that failed testing, heavy metals found in popular brands, and label accuracy scandals.
Blood sugar, cholesterol, gut health, and the metformin comparison. An evidence-based review of berberine's clinical data, realistic expectations, and who might actually benefit.
A head-to-head comparison of NMN and NR -- the two leading NAD+ precursors -- covering bioavailability, human trial data, cost, and the Sinclair controversy.
An honest look at senolytic compounds -- fisetin, quercetin, and dasatinib -- and whether clearing senescent cells is a viable longevity strategy today.
A scientist's breakdown of Bryan Johnson's anti-aging protocol -- what actually works, what's overkill, and how to get 80% of the benefit for $50/month.
The 10 foods most consistently linked to longer, healthier lives -- based on Blue Zone data and molecular biology -- with a practical weekly meal framework.
With 40-50% of the global population deficient, vitamin D is one of the most common nutritional gaps. We cover risk factors, testing, optimal doses, and why most people are taking the wrong amount.
Standard turmeric powder has near-zero bioavailability. We explain the curcumin absorption problem, compare Meriva vs BCM-95 vs piperine, and reveal what the clinical trials actually used.
Timing, interactions, absorption conflicts, and stacking principles. A practical guide to building a supplement stack that actually works -- and avoiding the redundancy trap.
Probiotics, prebiotics, digestive enzymes, L-glutamine, and bone broth -- we separate the evidence-based gut health supplements from the wellness hype.
Iron, folate, calcium, vitamin D -- the real science behind women's nutritional needs, why prenatal beats generic 'women's blends,' and how to stop overpaying for pink packaging.
We break down every AG1 ingredient, compare each dose to clinical evidence thresholds, and determine whether this premium greens powder delivers real value or just great marketing.
Up to 50% of adults are magnesium deficient. We compare glycinate vs citrate vs oxide vs threonate -- each form serves a different purpose. Here is how to choose the right one.
Type I and III collagen, hydrolyzed peptides, skin elasticity vs joint pain -- we break down what the clinical evidence actually supports and where the marketing outpaces the science.
Creatine is not just for men. We examine the evidence for creatine in women -- bone density, cognitive function, muscle maintenance, and why the fear of 'getting bulky' is a myth.
Which pre-workout ingredients actually improve performance? We rank every common ingredient by clinical evidence -- from caffeine and citrulline to the filler compounds padding your formula.
Tongkat ali, fadogia agrestis, turkesterone, ashwagandha -- we rank the most popular natural testosterone boosters by actual clinical evidence. Most disappoint.
Most melatonin products contain 10-30x the optimal dose. We review the MIT research, Zhdanova studies, and explain why 0.5-1mg outperforms the 10mg tablets lining store shelves.
A comprehensive evidence summary of creatine monohydrate covering loading vs maintenance protocols, who benefits most, and the myths that refuse to die.
Magnesium glycinate, melatonin, L-theanine, glycine -- we rank the most popular sleep supplements by clinical evidence strength and explain what actually works vs marketing.
Most multivitamins use cheap, poorly absorbed forms at doses too low to matter. We explain who actually needs one, what to look for, and why the form matters more than the label.
Dose matters, form matters, oxidation matters. We break down the omega-3 evidence -- triglyceride vs ethyl ester, EPA vs DHA ratios, and the rancidity problem nobody talks about.
Biotin deficiency is extremely rare, RCT evidence for hair benefits is nearly nonexistent, and megadoses can interfere with lab tests. Here is what actually works for hair.
Why supplement companies use proprietary blends, what they hide from consumers, the red flags to watch for, and how Biorank handles them in our scoring.
