Supplements: Cost Per Serving Comparison — Budget vs Mid vs Premium
Creatine monohydrate costs $0.03–0.05/serving (5g) in bulk. A commercial pre-workout providing equivalent actives (creatine 3g, caffeine 200mg, citrulline 6g, beta-alanine 3.2g) costs $1.50–3.00/serving — 10–15× the DIY equivalent of $0.25–0.35/serving from raw ingredients.
| Measure | Value | Unit | Notes |
|---|---|---|---|
| Evidence Tier | Reference | cost card | Price ranges based on bulk retail and online supplement marketplaces; updated 2026-Q1 |
| Cheapest Tier 1 Supplement | $0.03–0.05 | per serving (5g creatine) | Creatine monohydrate in bulk is the lowest cost-per-evidence supplement available |
| Commercial Pre-workout Cost | $1.50–3.00 | per serving | Typical branded pre-workout; actives often underdosed vs clinical doses |
| DIY Pre-workout Stack Cost | $0.25–0.40 | per serving (full clinical doses) | Creatine + caffeine tabs + citrulline + beta-alanine purchased separately in bulk |
| Protein Cost Benchmark | $0.50–1.50 | per 30g protein | Whey concentrate (budget) to whey isolate (premium); plant-based similar range |
| Annual Savings — DIY vs Commercial Pre-workout | $400–700 | USD/year (5× weekly use) | At 5 workouts/week: DIY saves $1.10–2.60/session vs commercial pre-workout |
Price benchmarks for every major supplement by tier. Cost-per-serving is calculated at the effective clinical dose, not per-gram. Budget = functional quality, no frills. Mid-range = common retail brands, often flavored. Premium = third-party tested, proprietary extracts.
Cost Per Effective Serving — Main Reference Table
| Supplement | Effective Dose | Budget ($/serving) | Mid-range ($/serving) | Premium ($/serving) | Best Value Source | Notes |
|---|---|---|---|---|---|---|
| Creatine Monohydrate | 5g | $0.03–0.05 | $0.07–0.12 | $0.12–0.20 | Bulk online (Bulk Supplements, NOW) | Commodity; Creapure certified = same molecule, higher QC |
| Whey Protein (per 30g protein) | 30g protein | $0.50–0.75 | $0.90–1.20 | $1.30–1.80 | Warehouse club (Costco) or bulk online | Concentrate = cheaper; isolate = less lactose; same muscle outcome |
| Caffeine | 200mg | $0.03–0.05 | $0.10–0.20 | $0.20–0.35 | Caffeine tablets, bulk online | Tablets preferred over powder (precise dosing) |
| Citrulline Malate | 6g | $0.20–0.35 | $0.45–0.70 | $0.80–1.20 | Bulk powder online | Pure citrulline is same efficacy; malate is the common form |
| Beta-Alanine | 3.2g | $0.08–0.15 | $0.20–0.35 | $0.40–0.60 | Bulk powder online | Split doses (≤1.6g) to minimize paresthesia |
| Omega-3 (per 1g EPA+DHA) | 1–3g EPA+DHA | $0.08–0.15 | $0.20–0.35 | $0.40–0.70 | Costco fish oil or bulk online | Check EPA+DHA concentration on label — not total fish oil mg |
| Magnesium Glycinate | 200mg elemental Mg | $0.10–0.18 | $0.25–0.40 | $0.50–0.80 | Online supplement retailers | Glycinate = highest absorption; oxide is cheapest but poorest absorbed |
| Vitamin D3 | 2000 IU | $0.02–0.04 | $0.05–0.10 | $0.12–0.20 | Any retailer in bulk softgels | D3 > D2 for raising serum 25(OH)D; 5000 IU = $0.04–0.08 at bulk pricing |
| Sodium Bicarbonate | 0.25g/kg (e.g. 18g for 70kg) | $0.01–0.03 | $0.10–0.20 | $0.20–0.40 | Food-grade baking soda (Arm & Hammer) | Pharmaceutical grade = identical molecule; food grade is fine |
| Dietary Nitrates (beetroot) | ~400mg nitrate | $0.30–0.50 | $0.70–1.20 | $1.50–2.50 | Concentrated beetroot shots | Whole food (beetroot juice, ~500ml) = $0.80–1.50; shots more convenient |
| Melatonin | 1mg | $0.02–0.04 | $0.05–0.10 | $0.10–0.20 | Generic pharmacy brand | No quality advantage at premium; 0.5mg as effective as 5mg for onset |
| Tart Cherry | 480ml juice equiv. | $0.40–0.70 | $0.80–1.20 | $1.50–2.50 | Concentrate (30ml per dose) | Freeze-dried capsules = consistent; juice = cheapest per dose if buying bulk |

| HMB (free acid) | 3g | $0.80–1.20 | $1.50–2.20 | $2.50–4.00 | Online supplement retailers | Expensive per serving; cost-justified only during cuts or detraining |
| Zinc (as zinc picolinate) | 25mg | $0.05–0.10 | $0.12–0.20 | $0.25–0.40 | Generic pharmacy or online | Picolinate > oxide for absorption; check label form |
| Collagen Peptides | 10g with Vitamin C | $0.30–0.50 | $0.60–0.90 | $1.00–1.80 | Bulk powder online | Vitamin C must be co-consumed; food source (orange juice) fine |
DIY Pre-workout vs Commercial Pre-workout
| Component | Clinical Dose | DIY Cost | What Pre-workout Provides | Pre-workout Cost |
|---|---|---|---|---|
| Creatine Monohydrate | 3–5g | $0.04 | 2–3g (often underdosed) | — |
| Caffeine | 200mg | $0.04 | 150–300mg | — |
| Citrulline Malate | 6g | $0.30 | 4–6g (varies widely) | — |
| Beta-Alanine | 3.2g | $0.12 | 1–3.2g | — |
| DIY total | Full clinical doses | $0.50–0.55 | — | — |
| Branded pre-workout | Often underdosed | — | Mixed; check label | $1.50–3.00 |
| Annual difference (5×/week) | — | $350–650 savings with DIY | — | — |
Note: Many commercial pre-workouts proprietary-blend their formulas, making individual ingredient doses unverifiable on the label. Efficacy is therefore unverifiable. DIY gives full control over dose and timing.
Where to Buy — Tier by Use Case
| Use Case | Recommended Source | Why |
|---|---|---|
| Bulk raw ingredients (creatine, citrulline, beta-alanine) | Bulk Supplements, Myprotein, NOW Sports | Lowest unit cost; third-party tested at most price points |
| Protein powder | Costco, Myprotein, online bulk | High volume = best value; price/30g protein is the key metric |
| Tested athlete (WADA-sanctioned sport) | NSF Certified for Sport, Informed Sport | Contamination testing; 15–40% premium worth it for competition |
| Pharmacy/grocery convenience | iHerb, Amazon, CVS | Mid-range; convenient for vitamins D, zinc, melatonin |
| Branded extracts (KSM-66, Creapure) | Direct brand or authorized retailers | Specific extract required for RCT replication |
How to use this data: Calculate cost at effective clinical doses, not label serving sizes. Many products list a half-dose as a “serving” — double the cost shown if the label dose is below clinical dose. DIY ingredient stacking is almost always cheaper than commercial formulations at equivalent doses.

Frequently Asked Questions
Does price correlate with quality for supplements?
Not reliably. Price correlates most strongly with marketing spend, brand positioning, and packaging complexity — not with clinical effectiveness. Creatine monohydrate is the most evidence-backed performance supplement in existence and costs $0.03–0.05/serving. Creatine HCl costs $0.30–0.60/serving with no evidence of superior outcomes. The premium tier (Creapure-certified, NSF-certified) does offer verified purity, which matters for competitive athletes — but that is a safety/compliance premium, not an efficacy premium.
Where should I buy supplements for best value?
Bulk powders from dedicated online suppliers (Bulk Supplements, Myprotein, NOW Sports) typically offer the best unit economics. Avoid supplement stores where margin is highest. For third-party tested products, NSF Certified for Sport and Informed Sport certifications add 15–40% to cost but provide contamination protection — worth it for tested athletes. Amazon is mid-range for convenience; Costco/warehouse clubs offer good value for protein and fish oil.
Are unflavored bulk ingredients worth the convenience tradeoff?
Yes for most use cases. Creatine monohydrate, citrulline, and beta-alanine are all relatively tasteless or mildly tart — they dissolve in a shaker with any beverage. Caffeine tablets are simpler than bulk caffeine powder (precise dosing, safer handling). The only ingredient where flavored products add meaningful experience is protein powder — unflavored whey is palatable but not enjoyable; the flavored version at 20–30% premium is often worth it for consistency.
How often should I compare prices?
Every 6–12 months, or when a new container is needed. Supplement prices fluctuate with ingredient commodity prices (creatine especially) and manufacturer promotions. Bulk buying (1kg vs 100g) saves 20–40% — worthwhile for daily-use supplements like creatine and protein where shelf life (1–3 years sealed) exceeds your use window.
