Sports Nutrition Supplements
Sports nutrition is the most evidence-rich supplement category — and also the most cluttered with junk science marketing. Creatine monohydrate is one of the most studied supplements in history. Whey protein has decades of research. But the shelves are also full of proprietary blends, underdosed pre-workouts, and "anabolic" formulas that don't work. We separate the science from the marketing.
Creatine
Creatine monohydrate is the single most researched and effective sports supplement available. Period. If you lift weights or do high-intensity exercise, this is the one supplement with near-universal support.
- Effective dose: 3-5g/day of creatine monohydrate. Loading phases (20g/day for 5-7 days) work faster but aren't necessary.
- What it does: Increases phosphocreatine stores in muscle, improving ATP regeneration during high-intensity efforts. Proven to increase strength, power output, and lean mass.
- Forms: Creatine monohydrate is the gold standard. Creatine HCl, buffered creatine, and other forms have no proven advantage despite higher prices.
Bottom line: Buy micronized creatine monohydrate in bulk powder. Brand doesn't matter much — it's a commodity ingredient. Don't pay 5x more for "advanced" creatine formulas.
Protein Supplements
Protein powder is a convenience product, not a magic muscle builder. If you hit your daily protein target through food, you don't need it. If you can't, it's an efficient way to close the gap.
- Whey Concentrate: 70-80% protein, retains beneficial peptides, more affordable. Good all-purpose choice.
- Whey Isolate: 90%+ protein, minimal lactose. Worth the premium if you're lactose-sensitive or cutting calories.
- Casein: Slow-digesting. Useful as a pre-bed protein source. Less practical for post-workout.
- Plant-based (pea + rice blend): Complete amino acid profile when combined. Comparable to whey for muscle protein synthesis when dose-matched for leucine (2.5-3g per serving).
Daily target: 1.6-2.2g protein per kg bodyweight for muscle building. More isn't better — the body can only use so much per day.
Pre-Workout & Performance
Pre-workout supplements range from clinically dosed formulas to glorified caffeine pills with pixie-dusted ingredients. Here's what actually has evidence:
- Caffeine (200-400mg): The most reliable performance enhancer. Improves endurance, strength, and focus. Tolerance builds with daily use.
- Beta-Alanine (3.2-6.4g/day): Buffers muscle acidity during high-rep sets. Causes harmless tingling. Needs to be taken daily (not just pre-workout) to saturate muscle carnosine stores.
- Citrulline Malate (6-8g): Improves blood flow and may reduce fatigue. Evidence is moderate but growing. Most products severely underdose this.
- Betaine (2.5g/day): May improve power output. Newer research, smaller effect size than creatine or caffeine.
Red flags: Proprietary blends, "matrix" formulas that hide doses, and any product listing 20+ ingredients — they can't all be at effective doses in one scoop.
HGH Releasers & Amino Acids
Human growth hormone (HGH) releasers use amino acid combinations to stimulate the pituitary gland's natural GH production. They're not synthetic HGH — they work with your body's existing hormonal signaling.
- L-Arginine (5-9g): Precursor to nitric oxide. Some evidence for GH stimulation when taken on an empty stomach before sleep or exercise.
- L-Glutamine (5g): The most abundant amino acid in muscle tissue. May support recovery and immune function during heavy training periods.
- Alpha-GPC (300-600mg): Choline compound with evidence for GH release and cognitive function. One of the better-supported nootropic-performance crossover ingredients.
- GABA (3-5g): May increase GH release when taken before sleep. Evidence is preliminary but interesting.
Realistic expectations: Natural GH releasers can modestly support your body's own hormone production — they won't produce the dramatic results of prescription HGH. They work best as part of a program that includes proper sleep, heavy compound lifting, and caloric sufficiency.

Buying Tips for Sports Supplements
Start with the basics: creatine monohydrate, adequate protein, and caffeine if you train early. These three have more evidence behind them than everything else combined. Only add specialty supplements once the fundamentals are locked in. For pre-workouts, look for full-disclosure labels (no proprietary blends) and check that key ingredients are at clinical doses — not just listed on the label at trace amounts.
Best For: By Training Goal
- Strength and power athletes: Creatine monohydrate (5g/day) is the single highest-impact supplement. Add adequate protein (1.6-2.2g/kg) and caffeine before training. These three cover 90% of what the evidence supports.
- Endurance athletes (runners, cyclists): Caffeine (3-6mg/kg body weight pre-event), beta-alanine for sessions lasting 1-4 minutes at high intensity, and electrolytes during long efforts. Creatine has emerging evidence for endurance recovery as well.
- Recovery-focused: Whey protein post-training, tart cherry extract (anthocyanins) for reducing muscle soreness, and omega-3 for inflammation management. L-glutamine may support immune function during heavy training blocks.
- Body composition (cutting): Protein at the higher end (2.0-2.2g/kg) to preserve muscle during caloric deficit. Caffeine for metabolic support and training performance. Creatine should be maintained even while cutting.
Cons & Considerations
- Creatine causes 2-4 lbs of water weight gain in the first 1-2 weeks. This is intracellular water (a sign it is working), not fat — but it surprises people who are tracking scale weight.
- High-dose caffeine (above 400mg/day) can cause anxiety, insomnia, elevated heart rate, and GI distress. Tolerance develops within 1-2 weeks of daily use, reducing performance benefits.
- Many pre-workout supplements contain undisclosed or banned stimulants. In 2023, the FDA recalled multiple pre-workouts containing DMAA and DMHA — compounds that can cause cardiovascular events. Stick to brands with third-party testing.
- BCAAs (branched-chain amino acids) are largely unnecessary if you consume adequate total protein. They were popular in the 2010s, but the evidence does not support spending extra on BCAAs when whole protein sources are available.
- HGH releasers produce modest natural GH increases — not the dramatic results of pharmaceutical HGH injection. Set realistic expectations about what amino acid-based GH support can accomplish.
How It Works
Fix Your Foundation
No supplement compensates for inadequate sleep, insufficient protein, or poor training programming. Get these right before spending money on supplements.
Start With Creatine
If you do any form of resistance training, 5g/day of creatine monohydrate is the highest-ROI supplement decision you can make. Take it daily, timing doesn't matter.
Audit Your Protein
Track your food for a week. If you're consistently under 1.6g/kg bodyweight, add a protein supplement. If you're hitting target through food, save your money.
Be Skeptical of Stacks
Pre-built "stacks" usually bundle a few good ingredients with a lot of filler. You're better off buying individual ingredients at proven doses than paying for a branded stack.
