No hype, no gimmicks — just what the research actually shows about the supplements people ask us about most. Written by the same team you talk to in the store.

Magnesium runs over 300 enzyme reactions in your body — muscle contraction, nerve signaling, blood sugar control, and sleep regulation all depend on it. Most people fall short of it from food alone, which makes this one of the easiest wins on the shelf.

Why it works:

• An estimated 45–50% of Americans don't hit the RDA for magnesium from food — supplementing closes that gap directly.
• Better magnesium status is linked to deeper sleep, fewer muscle cramps, and a steadier stress response.
• The form matters: glycinate absorbs well and is gentle on the stomach, making it the easiest one to stick with daily.

How to take it: 310–420mg/day covers most adults, and glycinate is the form we recommend for daily use — well absorbed, no stomach upset, great for winding down at night.

Grab this:Thorne Magnesium Glycinate — our top pick, third-party tested and highly absorbed. See every form we carry →

Creatine is the most researched supplement in sports nutrition, full stop — and the results back it up: more strength, more power, more lean mass when you train.

Why it works:

• Hundreds of trials over 30+ years consistently show gains in strength, power output, and lean mass with resistance training.
• Newer research also points to real cognitive and recovery benefits.
• It's not a stimulant, doesn't need cycling, and is well tolerated for daily long-term use.

How to take it: 3–5g a day, every day, no loading phase required — just consistency. Take it any time that's easy to remember.

Grab this:Nutrex Creatine Drive — pure monohydrate, the exact form the research is built on. Browse all creatine →

The B vitamins are your body's metabolic engine — they convert food into usable energy, support nerve function, and for a lot of people, fill a real and common gap.

Why it works:

• B12 deficiency is common — especially for anyone over 50, on metformin, or eating little to no animal products — and it's one of the easiest deficiencies to correct.
• Methylated forms (methylcobalamin, methylfolate) are the active forms your body uses directly, making them the more reliable choice.
• Folate status matters for anyone who could become pregnant, well before conception.

How to take it: A daily methylated B12/B6/folate combo is the simplest way to cover the bases, especially if you're vegetarian, vegan, or over 50.

Grab this:Superior Source Methyl B12 + B6 + Folate — active forms, dissolves under the tongue. See all B12 options →

Sea moss has had a huge moment — and underneath the trend is a genuinely mineral-dense whole food: calcium, magnesium, potassium, iron, zinc, iodine, and fiber, all in one plant.

Why it works:

• It's a concentrated source of trace minerals that are easy to run short on, iodine included — important for normal thyroid function.
• Sourcing is what separates a good sea moss product from a mediocre one — species, growing water, and testing all matter.

How to take it: Look for a product that names its seaweed species and gives an actual iodine number on the label — that's the mark of a serious brand, not just a trending one.

Grab this:Wild Craft Irish Moss — sourced and tested, no guesswork. Shop sea moss →

Good to know: On thyroid medication? Mention it at checkout — iodine-rich foods are worth coordinating with your dose.

Shilajit is a mineral-rich resin from the Himalayas that's become a go-to for energy and vitality — and while the research is still building, what's there is promising.

Why it works:

• Rich in fulvic acid and trace minerals, shilajit has early human research behind it for energy and vitality support.
• Purified, standardized extract is what the research is built on — that's the version worth having.

How to take it: Look for a purified, standardized extract with a stated fulvic acid percentage — that's the difference between a quality product and raw, unprocessed resin.

Grab this:Youtheory Shilajit — standardized and easy to take daily. See our shilajit options →

Protein powder is the simplest supplement on the shelf — a fast, convenient way to hit a number that fuels muscle, recovery, and staying full.

Why it works:

• Research supports 0.7–1g of protein per pound of bodyweight for anyone training regularly — noticeably higher than the general RDA.
• Whey digests fast and is ideal post-workout; casein digests slow and works well before bed.
• Plant blends (pea + rice) cover the full amino acid profile a single plant source often misses.

How to take it: A scoop after training, or anytime you're short on your daily total — the easiest habit to build for recovery and muscle.

Grab this:Earth Fed Muscle Whey — grass-fed, clean ingredient list, great flavor. Shop every protein we carry →

Glutamine is the most abundant amino acid in your body — heavily used during hard training and stress, and a smart add for anyone pushing their limits.

Why it works:

• Demand for glutamine rises with intense training, prolonged endurance work, and recovery from illness or surgery — exactly when extra support helps most.
• It plays a role in gut health research that's showing real promise.

How to take it: 5g post-workout or before bed is the standard approach — easy to mix into any shake.

Grab this:NutraBio Glutamine — pure, unflavored, mixes into anything. Browse glutamine →

This is one of the most common questions we get at the counter, and the answer's simple: EAAs are the complete toolkit, BCAAs are 3 of the 9 pieces.

Why it works:

• Muscle protein synthesis needs all 9 essential amino acids on board — EAAs deliver the full set, not just leucine, isoleucine, and valine.
• Research comparing the two head-to-head favors EAAs for actually building and preserving muscle.
• They're especially useful training fasted or in a calorie deficit, keeping aminos available when you need them most.

How to take it: Sip during or around your training session — a great way to stay fueled without added calories.

Grab this:NutraBio Alpha EAA — the complete 9, great flavor, no filler. Shop EAAs →

A well-dosed pre-workout is one of the most noticeable supplements you'll ever take — more energy, more output, better focus, from the first scoop.

Why it works:

• Caffeine reliably boosts power output and focus at the doses used in quality pre-workouts.
• Citrulline malate improves blood flow and reduces fatigue, giving you that pump and extra rep.
• Beta-alanine buffers fatigue in higher-rep work — that's the tingle doing its job.

How to take it: One scoop, 20–30 minutes before training. Start with a half scoop if you're new to caffeine-based formulas.

Grab this:Thorne Pre-Workout Elite — fully dosed, no proprietary blends hiding the numbers. See every pre-workout we stock →

Vitamin D is one of the most common shortfalls out there, and pairing it with K2 is what makes the combo work the way it should.

Why it works:

• Vitamin D helps your body absorb calcium; K2 directs that calcium into bone, where you want it.
• D3 (cholecalciferol) raises blood levels more effectively than D2, and MK-7 is the longer-lasting form of K2.
• Together they cover both sides of the equation — absorption and placement.

How to take it: A daily D3+K2 combo is the simplest way to stay on top of it, especially through the fall and winter months.

Grab this:Thorne Vitamin D/K2 — the exact combo and forms the research points to. Shop D3+K2 →

Electrolytes are having a moment — and for heavy sweat, heat, or long training days, they genuinely earn their spot in your routine.

Why it works:

• Sodium, potassium, and magnesium keep nerve signaling and fluid balance running the way they should during hard efforts.
• Houston heat and humidity mean real sweat loss — replacing it keeps performance and focus from sliding late in a workout.

How to take it: Mix one in with your water on training days, especially anything over 45–60 minutes or in the heat.

Grab this:Liquid I.V. — real sodium content, easy to carry, great in the Houston heat. Shop all electrolytes →

Omega-3s are some of the most consistently backed supplements on the shelf — real cardiovascular support, in a category most people are under-getting.

Why it works:

• EPA and DHA reliably lower triglycerides at the doses used in quality fish oil — one of the most consistent effects in the supplement world.
• Most people eating a typical diet get far more omega-6 than omega-3 — supplementing helps rebalance that ratio.
• Triglyceride-form (rTG) fish oil absorbs better than the cheaper ethyl-ester form.

How to take it: 250–500mg combined EPA+DHA daily covers general support; look for freshness and third-party testing on the label.

Grab this:NutraBio Omega-3 Fish Oil — rTG form, fresh, tested. See our fish oil lineup →

Ashwagandha is one of the best-studied adaptogens out there — real, repeated human trial results for stress, sleep, and recovery.

Why it works:

• Standardized root extract studies show meaningful drops in perceived stress and cortisol, plus better sleep quality.
• Resistance-trained users see real strength and recovery benefits on top of their training.

How to take it: 300–600mg/day of a standardized root extract, taken consistently — give it a few weeks to build.

Grab this:NutraBio Ashwagandha — standardized, KSM-66-grade root extract. Shop ashwagandha →

The right probiotic, matched to the right strain, is one of the most useful things you can add for gut health, digestion, and staying regular.

Why it works:

• Specific, well-studied strains genuinely help with digestive regularity, gut comfort, and supporting your system after a course of antibiotics.
• Multi-strain formulas with a high organism count give your gut the broadest support.

How to take it: Daily, consistently, ideally with food. Buy from somewhere that turns over stock — potency depends on freshness.

NMN is one of the most talked-about ingredients in the longevity space — a direct precursor to NAD+, the molecule your cells run on for energy.

Why it works:

• NAD+ levels decline with age, and raising them is one of the most active areas in longevity research right now.
• Early human studies show promising results for insulin sensitivity and physical performance in older adults.

How to take it: Taken daily, consistently — this is a long-game supplement, not a same-day-effect one.

Grab this:Natural Factors NMN Surge — third-party tested for actual NMN content, which matters a lot in this category. Shop NMN →

CoQ10 powers the energy production happening inside every cell in your body — and it's one of the few supplements with a clear, common reason to need more of it.

Why it works:

• CoQ10 production drops with age and drops sharply on a statin — a well-documented, well-understood mechanism.
• Research backs it as real support for heart health and statin users specifically, plus a role in migraine support.

How to take it: 100–200mg/day is the standard daily range. Ubiquinol absorbs better for older adults; ubiquinone works well for most everyone else.

Grab this:Natural Factors CoQ10 100mg — right in the sweet spot for daily use. Shop CoQ10 →

Good to know: On a statin? Mention it at checkout — CoQ10 is one of the most common pairings we recommend.

Better blood flow means a better pump, better endurance, and better performance — and the right ingredient makes all the difference here.

Why it works:

• L-citrulline raises blood arginine more effectively than arginine itself, with real exercise-performance research behind it.
• Dietary nitrate (beetroot) is a separate, well-evidenced pathway shown to improve exercise economy.

How to take it: 6–8g of citrulline malate about 30–45 minutes before training is the standard, well-researched dose.

Grab this:NutraKey Citrulline Malate — the dosed form the research is built on. Shop pump & nitric oxide →

The right enzyme, matched to the right food, is one of the fastest fixes for bloating and discomfort after eating.

Why it works:

• Lactase supplements are genuinely effective for dairy discomfort — one of the clearest wins in the category.
• A broad-spectrum blend covers carbs, protein, and fat in one go, making meals easier across the board.

How to take it: Take it right before or with the meal that tends to bother you — that's when it does the most work.

Grab this:Enzymedica Digest Gold for everyday meals, or Enzymedica DairyAssist if dairy's the culprit. Shop all enzymes →

Curcumin is one of the most useful anti-inflammatory ingredients around — as long as it's in a form your body can actually absorb.

Why it works:

• Human trials support real relief for joint discomfort, in some studies matching low-dose NSAIDs.
• Bioavailability-enhanced forms — piperine-added or phytosome — dramatically increase how much actually reaches your bloodstream.

How to take it: Daily, with a formula built for absorption — that's the single biggest factor in whether curcumin actually works for you.

Grab this:Gaia Turmeric Supreme — built for absorption, not just turmeric powder in a capsule. Shop turmeric →

Good to know: On a blood thinner or managing gallstones? Mention it at checkout before starting a high-dose extract.

Black seed oil is a real, research-backed ingredient — thymoquinone gives it genuine anti-inflammatory and metabolic support, especially in cold-pressed, quality-tested form.

Why it works:

• Human trials show real improvements in blood sugar markers and cholesterol as part of a broader routine.
• Cold-pressed sourcing is what preserves the thymoquinone content that makes it worth taking.

How to take it: A teaspoon of oil or a couple of capsules daily, ideally with food.

Grab this:Wild Craft Black Seed Oil — cold-pressed, quality-sourced. Shop black seed oil →

HMB helps protect the muscle you've already built — especially valuable for older adults and anyone coming back from a setback.

Why it works:

• Strong, repeated evidence supports HMB for preserving muscle in older adults and anyone in a recovery period — surgery, bed rest, illness.
• It works by directly reducing muscle protein breakdown, complementing whatever protein and training you're already doing.

How to take it: 3g/day, split into a couple of doses, taken consistently for the best results.

Grab this:NutraBio HMB — calcium HMB, the most studied form. Shop HMB →
