Protein & Performance
Third-party-tested protein powders, creatine, and electrolyte formulas for athletes and active adults — scored on the same rubric as the rest of our reviews.
Best Protein Powders, Scored on a Public Rubric
We scored six top Amazon protein powders (whey, casein, plant) on our 6-metric rubric: third-party testing, amino profile, value, and transparency.
Best Creatine Supplements, Scored on a Public Rubric
Creatine monohydrate is one of the most-studied supplements in sports science. We scored five widely-available Amazon picks on our 6-metric rubric.
Best Electrolyte Powders, Scored on a Public Rubric
Side-by-side scoring of six widely-available electrolyte powders on our 6-metric rubric — sodium-to-potassium ratio, sugar content, third-party testing, and value.
Best Creatine for Women, Scored on a Public Rubric
Creatine monohydrate is the same molecule for everyone — no 'women's blend' needed. We scored five third-party-tested picks on dose, form, and price per 5g.
Best Electrolytes for Keto, Scored Sodium-First
Keto depletes sodium fast. We scored five zero-sugar electrolyte mixes on sodium dose, potassium, magnesium, and clean label — so 'keto flu' doesn't sideline your training.
Best Salt Supplements, Ranked by Sodium Dose
If you train hard, eat low-carb, or sweat heavily, plain water isn't enough — you need salt. We scored six salt-forward electrolyte supplements on sodium dose, clean label, and value, led by LMNT.
Best Protein Powder for Weight Loss — High Protein, Low Sugar
The best protein powders for weight loss prioritize grams of protein per calorie, low sugar, and a clean label. We scored five high-protein, low-carb isolates and a plant pick.
Best BCAA & Amino Acid Supplements, Scored on a Public Rubric
BCAAs are only 3 of the 9 essential amino acids — a complete EAA blend or whole protein does more. We scored six widely-available amino formulas on our 6-metric rubric, powders and tablets.
Best Pre-Workout Supplements, Scored on a Public Rubric
Most of what a pre-workout does, caffeine does. We scored seven widely-available formulas on our 6-metric rubric, weighted hard toward disclosed doses and no proprietary blends.
The Best Shaker Bottles for Protein, Pre-Workout, and Electrolytes
We ranked shaker bottles on the only things that matter — how well they mix, how leak-proof the lid is, odor resistance, and durability. BlenderBottle, PROMiXX, YETI Yonder, Ice Shaker and more, with an honest take on the insulated premium.
The Best Plant-Based Protein Powders for Vegans and the Dairy-Free
Plant protein is a real, complete option when you buy it right — a pea/rice blend or pea isolate, clean label, third-party tested. We rank the best, and say plainly where whey still wins on price and leucine.
The Best Electrolyte Tablets and Capsules for Real Hydration
Sodium is the electrolyte that actually matters, and tablets let you dose it precisely without the sugar. We rank effervescent tabs, chews, and salt capsules for training, heat, and keto — with honest cons on each.
The Best Beta-Alanine Supplements for High-Intensity Training
Beta-alanine is one of the better-evidenced ergogenics — for the right kind of effort. We rank pure powders and tested options, explain the tingles, and give the dose that actually works (3.2-6.4 g/day).
The Best Supplements for Muscle Growth, Ranked on Hypertrophy Evidence
Creatine monohydrate and enough protein do the work. We rank six picks for muscle growth on the actual hypertrophy evidence, dose, and label honesty — and name the categories that do nothing.
The Best Supplements for CrossFit, Ranked for Repeatable High-Intensity Work
CrossFit asks for repeatable high-intensity work, not one max effort. We rank six supplements on that specific demand — creatine, electrolytes, beta-alanine, protein, magnesium, omega-3 — with live prices.
The Best Supplements for Runners, Ranked by What Actually Changes a Run
A carb-and-sodium drink mix is the best supplement for most runners — our pick is Skratch Labs Sport Hydration. Six picks ranked on evidence, dose, label honesty and live price, with iron tested first.
The Best Pea Protein Powders, Ranked by Dose and Label Honesty
Naked Pea is the best pea protein powder for most people — one ingredient, ~27 g per scoop, published heavy-metal testing. Six picks ranked on protein per scoop, label length, contaminant testing and live price.
