Peri-workout supplements use timing to boost athletic performance and maximize results.

Taken in conjunction with an exercise program, sport nutrients can enhance performance, muscle growth, recovery and more.

Peri-workout refers to sport nutrients taken in proximity to exercise. The right timing can help the best sport nutrients to work even better.

Strategic timing delivers nutrition to boost strength and endurance, optimize muscle recovery, and establish the consistent daily supplementation that yields the greatest athletic gains.

Today's top intra, pre and post workout supplements are:

  • Protein – Muscle building blocks taken before, during or after workouts, with post-exercise as the most anabolic time
  • Carbohydrate – Fuels muscle before exercise for peak intensity; refuels muscle afterwards for recovery 
  • Creatine - Loads muscles with ATP energy for explosive power and strength; take daily and consistently
  • Beta Alanine - Boosts carnosine to buffer muscles and fight fatigue, take daily and consistently
  • BCAA - Versatile athletic performance-enhancing benefits, plus muscle development and soreness reduction
  • L-Citrulline + L-Glutathione - Setria® Performance Blend; 2X nitric oxide stack for muscle-pumping circulation
  • Maritime Pine Bark - Super-antioxidant complex and nitric oxide booster for muscle pumps and protection
  • Caffeine - Performance-enhancer taken pre-workout for energy, alertness and intensity
  • L-Glutamine – Protects and restores muscle post-workout; fortifies immune system function
  • Pomegranate – Fruit antioxidant complex soothes muscle post-workout and promotes muscle recovery
  • Water + Salt + Electrolytes – Restores lost nutrients, maintains fluid balance and post-workout hydration
  • Iron - Key for athletes; the harder you train, the more you need

This guide discusses how each of these sport nutrients can be timed for maximum effect. We also reveal the products that best deliver each one's performance-enhancing benefits.


Consuming protein in proximity to workouts boosts muscle protein synthesis and enhances adaptive responses to training.1

In other words, taking protein powder not only promotes muscle growth, strength, repair and recovery, but it can be timed to zero in on the exact fitness benefits you seek.

Protein powder is a must-have for bodybuilding, endurance exercise and everything in between.

Pre-Workout Protein

Consuming protein before exercise is suggested to increase hypertrophy and accelerate recovery time. It may also have a carryover effect that continues feeding muscle after you finish your training session.

Intra-Workout Protein

Taking protein during your workout session provides muscles with an energy source for performance.

In addition, intra-workout protein has been linked to increased whole body and muscle protein synthesis as well as improved nitrogen balance.

Post-Workout Protein

Anabolic potential peaks immediately after exercise, and then declines over a course of 24 hours. During this time, muscle protein synthesis (MPS) is more sensitive to protein.2 

Taking protein after intense training stimulates MPS for up to three hours, while the anabolic window is still wide open. This protein strategy has greatest capacity to:3,4

  • Accelerate muscle recovery;
  • Reduce muscle soreness;
  • Enhance performance in your next exercise session;
  • Maximize muscle gains over time

But failing to consume protein after training (as a supplement or meal) slows down MPS and makes it harder to gain muscle.

MPS remains stimulated for up to 24 hours after exercise. Be sure to also get enough protein on rest day to maximize muscle repair and growth. 

Tip: Take protein before sleep for muscle growth. Consuming 40 g of protein at bedtime after a training day is shown to stimulate muscle protein synthesis and enhance muscle growth while you sleep.5


Athletes consume carbs as a readily available fuel source for muscle energy (in the form of blood glucose), as well as to load the liver and muscles with stored energy (in the form of glycogen).

Carbohydrate timing can produce different ergogenic benefits, all of which are related to fueling-up muscle energy.6

Pre-Workout Carbohydrate

Pre-Workout carbohydrate provides muscle fuel that can last up to 1 hour with typical sources, and up to 2 hours with the special type of carb called Karbolyn®.

Carbohydrate supplementation before exercise:

  • Gets glucose in the bloodstream for fast energy to start your session;
  • Stores glycogen in muscle to help you finish up strong;
  • Helps to ward off distracting feelings of hunger during the session 

Intra-Workout Carbohydrate

Fast-acting carbohydrates can be consumed intra-workout to maintain steady muscle energy and delay fatigue.7 

Carbohydrates are also beneficial when consumed over the course of intermittent sports events, like a tennis match, and events with several exercise bouts over a day, like a martial arts tournament.

Post-Workout Carbohydrate

Taking carbohydrate immediately after exercise, especially long-duration exertion to exhaustion, helps restore depleted glycogen levels to muscles and liver quickly and efficiently.8

Maxing out glycogen is key for powering performance in long-duration training and endurance events. 

Tip: Take carbohydrate + protein together after exercise. They work in synergy to boost MPS for enhanced muscle growth and recovery 


Creatine maximizes energy reserves for high-intensity exercise including strength training and sprinting is widely researched.

In literally hundreds of clinical trials, creatine has been shown to significantly increase strength, endurance and muscle mass.9

Pre, Post and Rest Day Creatine

Creatine works most effectively when muscles are saturated with it. This takes time and supplementation. 

Researchers have shown a 20% increase in muscle creatine can be achieved with two different creatine loading protocols:

  • 20 g creatine daily for 6 days
  • 3 g creatine daily for 28 days

After muscles are saturated, optimal levels can be maintained by taking 3 - 5 g creatine per day.

Tip: Taking protein + carbohydrate + creatine both pre- and post-workout has been shown in research to boost muscle creatine loading, glycogen recharging, strength and growth.10

Creatine must be taken in split doses, every day, including rest day.

For this reason, many incorporate creatine into their pre and post sport nutrition stack, and on rest days.

This pre-post-rest creatine strategy also works well with out next nutrient, which also works most effectively when loaded into muscles consistently over time.

Beta Alanine

Beta alanine boosts carnosine levels in muscle. Carnosine has a muscle-buffering effect that has been shown to:

  • Delay the onset of exhaustion in exercise11
  • Improve muscle power output in sprinting12
  • Unlock greater resistance training volume13
  • Improve muscular endurance capacity14
  • Boost high-intensity exercise performance15
Like Creatine, Beta Alanine delivers the greatest benefits when taken consistently, in split doses, every day, including rest day.

Taking Creatine + Beta Alanine together pre-workout, post-workout and on rest day enables the steady daily loading required for peak athletic performance and muscle development. 


BCAA (branched-chain amino acids) stimulates MPS, protects muscle, and enhances anaerobic and endurance exercise performance.

BCAA can function as a full-spectrum nutrient complex for peak training performance and muscle recovery. 

Pre-Workout BCAA

Research shows taking BCAA before exercise has a greater benefit for soreness than taking BCAA intra- or post.16

In endurance exercise, supplementing with BCAA before training may also block the fatigue-inducing brain chemical tryptophan, thereby extending time of exertion until exhaustion.17

Intra-Workout BCAA

Research has shown that taking BCAA during cycling exercise improves athletic performance.18

Taking BCAA during exercise has been shown to slow the rate of protein degradation and delay the depletion of muscle glycogen during endurance exercise.19, 20

Intra-exercise BCAA has been shown to enhance physical and mental performance in extended endurance exercise.21

Post-Workout BCAA

BCAA (specifically Leucine) taken before resistance training along with protein and carbohydrate has been shown to promote greater muscle protein synthesis when compared to just protein and carb.22

Tip: The International Society of Sports Nutrition suggests athletes take BCAAs (with carbohydrates) before, during and after exercise to maximize benefits that delay fatigue, sharpen focus, stimulate muscle protein synthesis and accelerate muscle glycogen restoration.23

L-Citrulline + Glutathione

Setria® Performance Blend is patented L-Citrulline + Glutathione. When taken together taken before exercise, it produces a powerful and sustained muscle-pumping nitric oxide boost.

Setria® Performance Blend raises and sustains nitric oxide in the bloodstream for twice as long as L-Arginine or plain citrulline.

Because it boosts muscle circulation fast and extends the boost until after exercise, Setria® Performance Blend can maximize athletic performance and muscle recovery. 

Setria® Performance Blend is a top sport nutrient shown in research to: 

  • Increase muscle mass and sustain gains24
  • Improve muscle performance, growth and recovery25
*Setria® Performance Blend is best taken before exercise.

Maritime Pine Bark Extract

Maritime Pine Bark Extract is another good nitric oxide booster. Within the bark are proanthocyanins, which are potent antioxidants that help athletes by:26

  • Stimulating and protecting nitric oxide to help boost and sustain blood flow to muscles;
  • Fighting cell-damaging free radicals generated during exercise;
  • Helping to soothe achy joints and sore muscles after exertion
*Maritime pine bark extract is best taken before exercise.


Caffeine will always be among the most popular supplements for both pre- and intra-training use. 

Athletes most often take caffeine for its energizing, focus-sharpening benefits, which help boost exercise intensity throughout a session.

  • Research shows caffeine enhances athletic metabolism, training performance and exercise enjoyment.27,28

The problem with caffeine in proximity to exercise: Side effects.

If you train in the morning, you may get jitters and crashes that make it difficult to perform optimally for the rest of the day. If you train in the evening, caffeine can interfere with the restful sleep you need to recover.

Tip: The top-rated caffeine pill uses a good strategy that combines low-dose caffeine, calming L-Theanine, and B-vitamins. As a result, it delivers better performance-enhancing benefits without side effects. 


Concentrated in muscle, L-Glutamine promotes transport of nitrogen, which is crucial for muscle energy, growth and recovery.

  • Exercising with intensity depletes glutamine.29
  • Low glutamine is linked to muscle wasting and soreness.30

As a sport nutrient, it helps to not only reverse exercise-induced depletions, but also kick-starts the muscle recovery process and optimizes immune function.

*L-Glutamine is a leading sport nutrient for after exercise.


Pomegranate fruit polyphenol antioxidants can help athletes by:

  • Boosting blood antioxidant levels, which protects nitric oxide and sustains its muscle-pumping activity31
  • Promoting muscle comfort after resistance exercise32
  • Speeding up muscle recovery after training33

For these reasons, as well as its ability to fight cell-damaging free radicals generated during exercise, pomegranate extract is a top sport nutrient to look for in 2020. 

*Pomegranate extract is most effective when taken after exercise. 


Water + Salt + Electrolytes

Training hard can make you lose salt, electrolytes and fluids, which exacerbates muscle catabolism, diminishes circulation, worsens performance and creates cramps, dizziness and side effects.34,35

Taking water, salt (especially Himalayan Pink Salt) and electrolytes (especially Potassium) before and after training maintains homeostasis during exercise and restores fluids and nutrients after.36

This pre, intra and post exercise hydration + supplementation strategy positions athletes for peak performance and optimal recovery. 


Iron enables the blood to transport and store oxygen, as well as assisting with cell energy production.37

Iron's various bioactivities are essential for strong performance during exercise and robust muscle growth afterwards. 

Athletes require more iron than non-trained individuals.

Intense exercise depletes iron. When levels get too low, the shortfall can create immune system challenges and reduce athletic performance.38

Iron may be taken before exercise, during exercise and on rest day to optimize performance and recovery.
