Only protein (when deficient) and creatine show consistent muscle growth benefits; most other supplements lack meaningful evidence.
Original: These are the top muscle growth supplements [46 studies reviewed]
TL;DR
Protein and creatine are the only supplements with strong evidence for muscle growth; others show minimal or no direct benefit.
Quick Answer
The video concludes that no supplement is a magic solution for muscle growth. The only scientifically supported foundation is protein supplementation, but only if dietary intake is below 1.6–2.0 g/kg of body weight. Creatine monohydrate is the most effective standalone supplement, providing modest gains in fat-free mass (1–2 kg) and improved work capacity. All other supplements—collagen, HMB, omega-3s, and citrulline—are either ineffective for hypertrophy when protein intake is adequate or offer only minor indirect benefits. Caffeine has no proven effect on long-term muscle growth.
Claims (10)
1. Taking creatine supplements may enhance thinking and memory in older people or those who are sleep-deprived or have cognitive difficulties, but it does not noticeably change thinking skills in healthy young adults.
2. Taking citrulline supplements may help improve blood flow and allow more repetitions during high-repetition, short-rest workouts, but it does not cause measurable increases in muscle size over time.
3. Taking HMB supplements does not significantly increase muscle growth in people who already eat enough protein, but might slightly affect muscle growth when calorie intake is very low or training intensity is extremely high.
4. Taking caffeine before exercise may make the experience more enjoyable, but it does not cause muscles to grow larger or stronger over time.
5. Taking fish oil supplements containing EPA and DHA may lead to very small or negligible gains in muscle size and strength for most people, and these changes are not large enough to be meaningful in a clinical or practical sense.
6. Taking collagen supplements does not help muscles grow larger if you are already consuming enough total protein and vitamin C, because collagen does not contain the right amino acids or biological mechanism to directly stimulate muscle growth.
7. Taking creatine supplements leads to higher levels of creatine in muscles, improves the ability to regenerate energy during intense workouts, and over 8 to 12 weeks, allows for more total training and measurable muscle growth.
8. Many fish oil supplements sold commercially do not contain the amount of EPA and DHA claimed on their labels, show signs of degraded fats beyond safe limits, and may contain harmful contaminants like heavy metals.
9. Taking extra protein supplements can lead to greater muscle growth only if your total daily protein intake is less than 1.6 grams per kilogram of body weight. If you already consume more than this amount, additional protein supplements do not result in further muscle growth.
10. Using drugs to block myostatin can reduce the amount of muscle lost when a person is consuming fewer calories, by about half compared to not using such drugs.
Key Takeaways
- •Problem: People think taking many supplements will make them grow muscle faster, but most don't actually help.
- •Core methods: Protein supplementation, creatine monohydrate, collagen with vitamin C, HMB, omega-3 fatty acids, citrulline.
- •How methods work: Protein fixes muscle if you don't eat enough; creatine helps you lift more by giving muscles quick energy; collagen supports tendons but doesn't build muscle; HMB might help only if you're starving or overtraining; omega-3s reduce swelling and help joints; citrulline makes blood flow better during workouts but doesn't make muscles bigger.
- •Expected outcomes: You gain 1–2 kg of muscle-like mass with creatine if you're not getting enough protein, and protein helps if you're deficient. Everything else gives tiny or no muscle growth.
- •Implementation timeframe: Creatine and protein show results in weeks to months; other supplements may take months to show minor recovery benefits, but no significant muscle growth.
Overview
The problem of identifying effective muscle growth supplements is complicated by widespread misinformation and marketing claims. This video addresses it by analyzing 46 long-term hypertrophy studies to determine which supplements have robust scientific backing. The solution preview identifies protein (as a dietary foundation) and creatine (as the primary adjunct) as the only consistently effective agents, with other supplements offering conditional, indirect, or negligible benefits.
Key Terms
How to Apply
- 1.Calculate your daily protein intake: aim for at least 1.6 g per kg of body weight (e.g., 70 kg person = 112 g/day); if you fall short, use whey or casein protein powder to meet the target.
- 2.Take 3–5 grams of creatine monohydrate daily, regardless of body weight; women can use 3 g, men can use 5 g.
- 3.If you don't eat fatty fish twice a week, supplement with 1–2 grams of EPA+DHA daily from a verified brand (e.g., Labdoor-certified) to support recovery and joint health.
- 4.Take 6–8 grams of citrulline malate 60 minutes before workouts if you perform high-repetition sets (15+ reps) with short rest periods (under 90 seconds).
- 5.Avoid collagen, HMB, and high-dose creatine (above 5 g/day) unless you have specific medical or recovery needs, as they offer no proven muscle growth benefit.
- 6.Do not rely on caffeine for muscle growth; use it only if it improves workout enjoyment, but do not expect it to increase strength or size.
You will experience modest muscle growth (1–2 kg fat-free mass) primarily from creatine and adequate protein intake. Other supplements may improve recovery and joint comfort but will not significantly increase muscle size. You will avoid wasting money on ineffective products like HMB, excessive collagen, or mislabeled fish oil.
