As we get in to supplementation for training, things can get very specific as we start dialing in to a stimuli-based approach as well as considering individual differences. If you are interested in learning more about the details of each, consider taking the Nutrition & Program Design for Trainability course.
In this article we’ll be focusing on the basics that can apply within the three phases of training or for certain goals. There are several others that can be used conditionally based on the training and goal.
Many of the essentials also play a role in peri-workout nutrition and can be varied based on the type of training. For example, an activated B-complex can be a good option pre-workout to support energy production and mental focus while taurine can be a staple addition post-workout to help with calming the nervous system, facilitating electrolyte balance, and aiding in glucose sensitivity.
Keep in mind that ALL of these have an “it depends” factor that influence if or when you might apply them.
BCAAs can be a useful addition intra-workout to support the liver during metabolically demanding workouts or when glycogen stores might be low. Most often this would be utilized in a hypertrophy or metabolic phase.
Glutamine can play several important roles when utilized around training. If carbohydrates are low, large doses of glutamine can aid in glycogen replenishment in the absence of glucose (1,2).
It also helps the kidneys buffer acid. This can be helpful in phases where there is a lot of lactate or metabolic waste being produced during training. 5-10g intra-workout is usually sufficient for this aspect and it does not detract from the metabolic benefits of lactic acid production during training.
Glycine has a useful function as a growth hormone secretagogue. This means that it supports and enhances the production of GH (3,4). For this use, glycine can be used after a metabolic workout to promote the body’s natural GH production. However, this also should be in an instance with little to no carbs. Otherwise an elevation of insulin can inhibit the production of growth hormone after the session.
Tyrosine can be beneficial pre-workout in all three phases phases to improve focus and neurological drive. It has the benefits of both increasing the neurotransmitter dopamine as well as playing a role in thyroid hormone production , which can be helpful for a fat loss goal. The amount of this amino will depend on the type of training session as some stimuli will be better suited to a lower amount of dopamine than others. In addition, too much dopamine can increase irritability and make it difficult to focus during the session.
Acetyl-L-Carnitine is useful for mental focus and amplifying the effects of nutrients that increase the neurotransmitters dopamine and acetylcholine. This form is primarily used because it more easily crosses the blood-brain barrier. It is not used with the intent of increasing fat burning directly by enhancing transport of fatty acids into the mitochondria like most people associate with carnitine supplementation.

These are just some of the basics training specific possibilities with many more depending on individual needs and goals. The Nutrition & Program Design for Trainability course does in depth on pre, intra, and post-workout nutrition and supplementation for each phase of training if you want to learn more.
