The Dosage of Pre-Workout Supplements

Manufacturers use different formulations and doses of ingredients for pre-workout supplements, so it’s best to follow the dosage recommendations on the product label.

A study was conducted in 2019 to look for a common ingredient profile among pre-workout supplements to compare their dosages and establish its effectiveness.(1) It was found that beta-alanine and citrulline were the most common compounds found in multi-ingredients pre-workout supplements. 

Since some companies use proprietary blends, the researchers recommended that consumers choose products where all the ingredients are listed. You should make sure to check if certain ingredients are under-dosed, such as beta-alanine (2) and creatine (3). 

They further advised lowering the consumption of ingredients like caffeine or niacin to prevent any adverse effects of excess ingestion of these compounds. So cut down your coffee intake and other multivitamins or B-complex capsules, if any. The guidance of a health professional will be helpful in determining the right dosage in conjunction with the product label that gives clear instructions for use.

As nutrient requirements vary between individuals, the dosage of a pre-workout supplement depends upon the body type, its nutrient requirement and the health goal of the person. 

Possible Side Effects of PreWorkout Supplements

Pre-workout supplements contain multiple ingredients. Their manufacturing processes usually ensure only the best and pure ingredients are used in the formulations of these products. Yet, an ingredient or it’s quantity present in these dietary foods can trigger undesirable effects. Here are some of the common side-effects and ways to avoid them. 

Caffeine: Caffeine is one of the chief components in pre-workout supplements. (4) While it enhances strength and performance there is a downside to its high consumption. Too much caffeine can lead to headaches, jitteriness, drowsiness, and anxiety. One cup of coffee delivers only 95 mg of caffeine. Some supplements deliver more than 450mg of caffeine in every serving. 

Studies suggest that 400mg of caffeine per day (6) which is equivalent to 6mg per kg (for a 65 kg person) of body weight for an adult will not result in serious side effects of toxicity, changes in behavior, cardiovascular effects, and male fertility effects. 

Women at their reproductive age should moderate their caffeine intake to less than or equal to 300mg per day and children should consume less than or equal to 2.5 mg per kg body weight.

Creatine: Creatine is a well-known ingredient in supplements that decreases acidity in muscles while exercising. (7). 

It has a loading phase of 20 grams a day for 3 days and then 3 to 5 grams per day. This method can cause digestive problems like bloating. If you can wait up to 3 to 4 weeks to notice results then a single daily dose of 3 to 6 grams will be without side effects. 

Beta-alanine: Beta-alanine in doses of 4 to 6 grams increases performance in high-intensity exercises that lasts between 1 to 4 minutes. (8

It reduces fatigue. However, there is a mild side effect of a tingling sensation to the hands and feet. The best way to avoid this sensation is to further divide the 4 to 6 grams dose to separate two doses of 2-3 grams each. 

Niacin: Niacin in pre-workout supplements can cause skin-flushing that results in red patches, especially when doses of this ingredient are 500mg or more. 

A review published in 2010 advises a slow increase of niacin dosage from 0.5 to 1.0 grams a day during the first 8 weeks and then from 1.0 to 2.0 through a single titration method (9). 

The Final Note

Pre-workout supplements may support you in achieving your health goals. Checking the list of ingredients and assessing your tolerance level to the dosage will help in gaining the health benefits of these dietary foods. 

Ensure you are free from any underlying medical condition and you are not pregnant or nursing if you plan to use these supplements. They are meant as an addition to a healthy diet with natural sources of food and not as a substitute. 

It’s best to take pre-workout supplements about half an hour before your workout rather than right before you start exercising or during your workout. Most of these supplements come in the form of a powder that can be mixed into shakes, making it easy to transport and use when needed. 

Depending on our fitness goals, choose a suitable pre-workout supplement from our top 10 and get to the next level of your fitness journey.
