**Performance‑Enhancing Supplements – What They Are, How They Work, and Why Their Use Can Be Risky**

| Category | Typical Examples | Mechanism of Action (simplified) | Evidence for Effectiveness | Common Health Risks / Concerns |
|----------|------------------|---------------------------------|----------------------------|--------------------------------|
| **Nutrient‑based** | Creatine monohydrate, beta‑alanine, branched‑chain amino acids (BCAAs), citrulline malate, sodium bicarbonate | Increase muscle energy stores, buffer lactic acid, improve blood flow or nitrogen balance | • Creatine: 5–15 % ↑ in strength & power
• Beta‑alanine: ↑ muscular carnosine → improved high‑intensity work
• BCAAs: limited evidence; may spare glycogen but not clearly superior to protein | Generally safe; creatine can cause mild GI upset, water retention; sodium bicarbonate may cause nausea or diarrhea |
| **Nutrient Timing** (carbs/protein immediately post‑exercise) | ↑ muscle glycogen resynthesis & protein synthesis | Small benefit (~5–10 % faster glycogen restoration); may aid recovery but not essential for strength | None significant |
| **Sleep / Recovery** | 7–9 h/night → hormonal balance, protein synthesis | Chronic sleep deprivation reduces IGF‑1 and increases cortisol; can impair performance by ~3–5 % | Not a supplement per se |

### 2. Supplements That *Might* Enhance Strength (Evidence ≤ 4 yrs)

| Supplement | Key Evidence (Human RCTs) | Typical Dose | Practical Considerations |
|------------|---------------------------|--------------|--------------------------|
| **Creatine Monohydrate** | Meta‑analysis 2020: ~0.9 % ↑ 1RM; benefits in older adults and untrained males; works in all populations with loading or maintenance. | Loading: 20 g/day (5 × 4 g) for 5–7 days, then 3–5 g/d. Maintenance: 3–5 g/d. | Cheap, well‑studied; minor GI upset possible; monitor water intake. |
| **Beta‑Alanine** | 2018 meta‑analysis: improves muscular endurance; no direct strength gains but allows higher training volume → indirect strength benefit. | 4–6 g/d split dosing (2 × 2 g). | Tingling (paresthesia) at high doses; can be mitigated with smaller doses or Caps. |
| **Creatine Monohydrate** (already included, but confirm dosage) | 3–5 g/d; loading phase optional. | Same as creatine above. |
| **HMB (β‑Hydroxy‑β‑Methylbutyrate)** | 1.5 g/d divided into 3 doses. | Some studies show slight strength increase, especially in novices or after detraining. |
| **Omega‑3 Fatty Acids** (EPA/DHA) | 2–4 g/day of combined EPA+DHA. | May reduce muscle soreness and inflammation; potential for improved recovery. |

### Recommended Supplemental Regimen

| Supplement | Dose & Timing | Rationale |
|------------|---------------|-----------|
| **Creatine monohydrate** | 5 g once daily (preferably post‑workout or with a carbohydrate source) | Maximizes intramuscular stores; enhances phosphocreatine resynthesis for high‑intensity work. |
| **Protein shake (whey)** | 20–30 g immediately after workout | Provides essential amino acids for muscle protein synthesis, particularly leucine (~2.5–3 g). |
| **Omega‑3 fatty acids** | 1–2 g EPA/DHA daily | Anti‑inflammatory; supports recovery and may improve insulin sensitivity. |
| **Multivitamin/mineral** | As directed | Addresses micronutrient needs for energy metabolism, antioxidant defense, and muscle function. |

> **Note:** The effectiveness of these supplements depends on proper dosing, timing, and adherence to overall diet and training. Excessive supplementation can lead to adverse effects or nutrient imbalances.

### 3. How Does the Body Use Dietary Energy? (4–6 % of the Day)

| **Stage** | **Key Processes & Energy Cost** |
|-----------|---------------------------------|
| **Ingestion & Digestion** | Mechanical & enzymatic breakdown; ~5 % of basal metabolic rate (BMR) to transport nutrients. |
| **Absorption & Transport** | Carriers move glucose, fatty acids, amino acids across enterocytes and into circulation (~2 % of BMR). |
| **Metabolism (Oxidation)** | Substrates undergo glycolysis → TCA cycle → oxidative phosphorylation; ATP yield ~30–32 mol per mol glucose. |
| **Storage** | Excess glucose → glycogen in liver/skeletal muscle (~3 % of BMR); fatty acids → triglycerides in adipose tissue (~4 % of BMR). |
| **Protein Turnover** | Synthesis & degradation cycles consume ~10–15 % of resting energy expenditure. |

### 2. Muscle Metabolism During Resistance Training

- **Energy Demand:**
- A single set (10–12 reps) can consume ~25–30 kJ (~6–7 kcal) per muscle group.
- Total session (~4–5 sets per exercise) leads to >200 kJ (~48 kcal) expenditure in working muscles.

- **Metabolic Pathways:**
- **Phosphagen System (ATP‑PCr):** Provides ~30 s of high‐power output. Rapidly depleted PCr; replenished over 10–15 min.
- **Anaerobic Glycolysis:** Generates lactate and H⁺, contributing to muscle fatigue but also providing a stimulus for hypertrophy via metabolic stress.
- **Oxidative Metabolism:** During rest periods (especially in circuit training), muscles rely on oxidative phosphorylation to recover PCr and clear metabolites.

- **Recovery Dynamics:**
- Post‑exercise lactate clearance follows first‐order kinetics with a half‐life of ~5–10 min, influenced by muscle perfusion and substrate availability.
- Rest intervals >90 s allow >70 % PCr resynthesis; shorter intervals (
