Pre- and Post-Workout Supplements to Maximize Exercise Performance

January 17, 2024

Achieving peak performance in your workout regimen requires more than just dedication and sweat. Nutrition is crucial for fueling your body before and after exercise, and that's where pre- and post-workout supplements come into play. These supplements can optimize your workouts, enhance recovery, and support overall fitness goals. Whether you’re a dedicated athlete or just starting your fitness journey, pre- and post-workout supplements can help you maximize your exercise performance.

What are Pre-Workout Supplements?

Pre-workout supplements are nutritional products you take before engaging in physical exercise or strenuous activities. These supplements provide the body with targeted nutrients that enhance performance, energy levels, and focus during workouts. While the exact composition of pre-workout supplement blends can vary, they typically contain a combination of ingredients aimed at promoting increased endurance, improved strength, and heightened mental alertness. Building your own pre-workout stack provides peace of mind, as you know what you’re taking exactly instead of trusting a proprietary blend that may conceal the exact amounts of each ingredient. It also allows you to target specific fitness goals, such as:

Increased Energy Levels:
- Common ingredients:
  1. Caffeine: A stimulant that helps increase alertness and energy levels. Caffeine can enhance physical performance by reducing perceived effort and fatigue. [1 - 8]
  2. Beta-alanine: An amino acid that delays the onset of fatigue by increasing carnosine concentrations in muscle tissue. Carnosine acts as a pH buffer, helping to neutralize the acidity produced during exercise. By counteracting the acidosis that occurs during intense exercise, beta-alanine helps delay the onset of muscle fatigue. [9 - 12]
  3. Creatine monohydrate: A compound that aids in producing ATP (adenosine triphosphate), the body's primary energy source for muscle contractions. Creatine supplementation may contribute to increased strength and power. [13 - 17]
- Function: Boosting energy levels, enhancing focus, and delaying fatigue during exercise.
Improved Endurance:
- Common ingredients:
  1. Branched-Chain Amino Acids (BCAAs). Leucine, isoleucine, and valine are the three amino acids collectively known as the BCAAs. These are crucial for protein synthesis. The body can also use them as a rapid energy source to sustain energy during endurance workouts. [18 - 25]
  2. Beta-alanine. In addition to improving energy levels, beta-alanine can enhance endurance by buffering the acidic environment created during high-intensity exercise. [9 - 12]
- Function: BCAAs help preserve muscle glycogen, while beta-alanine buffers acidic buildup, delaying muscle fatigue for better endurance.
Enhanced Blood Flow:
- Common ingredients:
  1. Nitric oxide boosters like arginine or citrulline. L-arginine is an amino acid and precursor to nitric oxide. L-citrulline is another amino acid that is a crucial player in the nitric oxide pathway. Unlike L-arginine, L-citrulline converts to L-arginine in the kidneys, leading to a more sustained increase in arginine levels. Sustained arginine elevation may result in prolonged nitric oxide production and improved exercise performance. [26 - 30]
- Function: Increased blood flow to muscles, delivering more oxygen and nutrients for improved performance.
Mind-Muscle Connection:
- Common ingredients:
  1. Nootropics like tyrosine or acetyl-L-carnitine (ALCAR). Tyrosine helps synthesize dopamine neurotransmitters that influence focus and mental alertness. It may also delay the onset of mental fatigue during prolonged or demanding exercise by supporting neurotransmitter balance. ALCAR can cross the blood-brain barrier, where it acts as a precursor to acetylcholine, a critical neurotransmitter for cognitive function. Some studies suggest that ALCAR may have cognitive-enhancing effects, including improved focus and mental clarity. It also enhances energy metabolism by transporting fatty acids into the mitochondria for energy production. [31 - 37]
- Function: Enhancing cognitive function, promoting focus, and establishing a robust mind-muscle connection.

What are Post-Workout Supplements?

Post-workout supplements are the counterparts of pre-workout supplements. They support exercise recovery and help repair and replenish the body after exercise. These supplements provide specific nutrients that can help optimize recovery, reduce muscle soreness, and support muscle protein synthesis. The primary goals of post-workout supplementation are to replenish essential amino acids, reduce muscle protein breakdown, and promote muscle repair and growth.

Muscle Recovery:
- Common ingredients:
  1. Protein (whey, casein). Protein is a crucial component of post-workout supplementation because it provides the essential amino acids needed for muscle repair and growth. Whey protein is fast-acting and works best when taken shortly after finishing a workout. Casein digests more slowly. It forms a gel-like substance in the stomach, resulting in a gradual amino acid release into the bloodstream over time. Most people take it before bedtime to provide a slow and steady release of amino acids during the night, supporting muscle recovery during sleep. PureBulk also carries rice protein and pea protein for individuals following a plant-based diet or those with lactose intolerance. [38 - 42]
  2. BCAAs. You can take BCAAs before, during, and after a workout, as these incredibly versatile amino acids perform numerous functions to support exercise performance and recovery. They help reduce muscle soreness and promote muscle recovery by stimulating muscle protein synthesis. They can also help reduce muscle protein breakdown during and after exercise. Although scientists don’t fully understand the mechanism, research shows that BCAAs help reduce delayed onset muscle soreness (DOMS). [18 - 25]
  3. Glutamine. Glutamine is a precursor to amino acids that synthesize collagen, a structural protein that participates in muscle repair. It can also convert to glucose and replenish glycogen stores during exercise recovery. Like BCAAs, glutamine has unknown mechanisms that decrease DOMS. Researchers believe this may be due to its anti-inflammatory properties. [43 - 50]
- Function: Aiding muscle repair, reducing muscle soreness, and replenishing amino acid stores.
Reduced Inflammation:
- Common ingredients:
  1. Omega-3 fatty acids. Omega-3s like eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have powerful anti-inflammatory properties. They reduce pro-inflammatory markers associated with intense exercise. They also produce specialized pro-resolving lipid mediators (SPMs), which help clear inflammatory cells and shorten the inflammatory response duration. Additionally, omega-3s support cartilage health and reduce joint pain and stiffness. Fish oil capsules are a rich source of omega-3 fatty acids. [51 - 59]
  2. Curcumin. Curcumin is the active ingredient in turmeric with antioxidant and anti-inflammatory properties. It inhibits pro-inflammatory pathways that would otherwise trigger inflammatory cytokines. Curcumin supplementation can also decrease circulating pro-inflammatory cytokines. Curcumin possesses strong antioxidant properties, helping neutralize free radicals generated during exercise. Intense physical activity can lead to oxidative stress, and curcumin's antioxidant activity may contribute to reducing exercise-induced inflammation. [60 - 67]
- Function: Combating post-exercise inflammation and supporting joint health.
Rehydration:
- Common ingredients:
  1. Electrolytes. Electrolytes help regulate the fluid balance within and outside cells. Sodium, potassium, and chloride are critical electrolytes for osmotic balance. They ensure the appropriate water distribution between cells and the extracellular space. [68 - 69]
- • Function: Replenishing electrolytes lost through sweat, maintaining proper fluid balance.

What to Consider When Choosing Pre- and Post-Workout Supplements

Personal Goals and Tolerance:
- Tailor your supplement intake based on individual fitness goals, tolerance to specific ingredients, and overall health.
Timing Matters:
- Consume pre-workout supplements 30-60 minutes before exercise.
- Post-workout supplements are most effective when taken within 30 minutes after exercising, except for casein protein, which works best when taken before bed or ahead of fasting periods.
Hydration is Key:
- Adequate water intake is crucial for pre- and post-workout supplements’ effectiveness.

Pre- and post-workout supplements can significantly enhance your exercise routine, helping you achieve your fitness goals faster. However, it's essential to understand your body's needs, choose the right supplements, and integrate them into a well-balanced diet and exercise plan. Always consult with a healthcare professional or a nutritionist before introducing new supplements to your routine to ensure they align with your unique health profile and fitness objectives.
