Evidence First: How to Judge a Supplement

Look for randomized trials, meta-analyses, and mechanisms that make sense. Creatine monohydrate, caffeine, beta-alanine, and dietary nitrates consistently show benefits. If research is thin, inconsistent, or industry-funded without replication, be skeptical. Evidence should guide your cart and your cup.

Evidence First: How to Judge a Supplement

Shiny graphics and dramatic claims can tilt expectations, boosting placebo effects or fueling nocebo worries. BCAA powders seem exciting, yet add little if daily protein is already sufficient. Beware proprietary blends that hide underdosed ingredients behind fancy names and secret ratios.

Performance Boosters That Actually Work

Creatine monohydrate supports strength, power, and high-intensity capacity. A daily 3–5 grams works; loading is optional for faster saturation. Water weight increases are normal intracellular hydration, not fat. Healthy people tolerate it well, but consult your clinician if you have kidney issues or concerns.

Performance Boosters That Actually Work

Caffeine reliably improves endurance, power, and focus at roughly 3–6 mg per kilogram, taken 30–60 minutes pre-session. Individual sensitivity varies widely, and late doses can wreck sleep. Test smaller amounts first, track your response, and cycle if tolerance dulls the effect.

Dietary nitrates from beetroot juice, spinach, or arugula can raise nitric oxide, improving blood flow and economy. Benefits are modest but real for some endurance efforts. Avoid antibacterial mouthwashes near dosing, which may blunt conversion. Start small before key races to dial in stomach tolerance.

Recovery and Muscle: What Helps, What Doesn’t

Aim for 1.6–2.2 grams of protein per kilogram daily, mostly from foods. Whey is convenient, fast-digesting, and rich in leucine to trigger synthesis. Hitting a leucine threshold—roughly 2–3 grams per meal—matters. Choose what helps you consistently meet targets, not what screams loudest.

Overhyped or Ineffective for Most Athletes

BCAAs alone seldom boost muscle growth when total protein is already adequate. If you cannot eat, essential amino acids or whey provide a more complete signal. Most lifters will get better results from simply meeting daily protein targets across well-distributed meals.

Overhyped or Ineffective for Most Athletes

Herbal ‘test boosters’ like tribulus or D-aspartic acid routinely disappoint in rigorous trials. Hormones respond more to sleep, calories, training load, and overall health. If numbers seem off, talk to a professional instead of chasing expensive capsules with dramatic but unsupported promises.

Safety, Dosing, and Stacking Without Guesswork

Check ingredient amounts, serving sizes, and forms—creatine monohydrate over trendy esters, standardized extracts over vague herbs. Watch for allergens, sugar alcohols, and excessive stimulants. If you see proprietary blends, ask why dosing is hidden. Good products have nothing to hide on the label.

Safety, Dosing, and Stacking Without Guesswork

Build around proven basics, then add carefully. Track one change for two to four weeks before layering another. Beta-alanine needs sustained intake for carnosine loading; tingles are harmless but real. Consistency beats novelty, and your logbook beats influencer excitement every single training block.

A runner’s beetroot experiment

Before a 10K, Maya trialed beet juice during easy runs to check her stomach. On race week she timed doses earlier, skipped mouthwash, and felt smoother at tempo pace. The clock didn’t lie—small gain, real confidence. Test protocols early and personalize them patiently.

A lifter’s second try at creatine

Jordan quit creatine once, blaming ‘bloat.’ Later he tried a steady 3 grams daily with more water and realistic expectations. Strength climbed, sets felt sturdier, and bodyweight stabilized after a brief uptick. Sometimes the supplement works; sometimes the plan—and the patience—make it work.

The late-night pre-workout mistake

Sam loved the focus from a strong pre-workout but trained at 8 p.m. Sleep cratered, recovery lagged, and progress stalled. Switching to afternoon sessions—and a smaller caffeine dose—restored deep sleep and performance. The best supplement schedule respects your circadian rhythm as much as your ego.

Build a minimalist, effective stack

Start with training, protein targets, and sleep. If appropriate, add creatine, caffeine, and maybe nitrates for endurance blocks. Put each on trial with clear goals and timelines. Simplicity reduces cost, confusion, and side effects—while amplifying the signal that actually moves your performance forward.

Track outcomes, not vibes

Keep a log of lifts, splits, RPE, sleep, mood, and any side effects. Compare weeks, not workouts. If a supplement does not move objective markers after a fair trial, retire it. Data-driven decisions turn curiosity into progress, not clutter into kitchen-counter chaos.
