Supplements For CrossFit Athletes

By Xwerks Nutrition

What Supplement Stack Should You Take For CrossFit?

The Essentials

The Basics Vitamin D+K - Studies show over 40% of adults (80% of African Americans) are deficient in Vitamin D. Supplementing with Vitamin D has multiple benefits such as; increased mental function, bone health, immune health and well-being. It can also reduce the risks of cancer, heart disease, multiple sclerosis and diabetes. People deficient in Vitamin D can also experience increased Testosterone levels by supplementation. Take at least 2,000 IU a day along with 500mcg of Vitamin K, to increase effectiveness. Must be taken with fat for proper absorption.

ZMA - 35-45% of adults do not get proper Zinc intake and over 70%, according to the World Health Organization, do not ingest enough Magnesium. Zinc is an antioxidant and immune-boosting supplement. Zinc is most commonly supplemented to reduce the frequency of illness and to support optimal levels of testosterone. Zinc is lost through sweat, so you can imagine it is very important for a CrossFitter to take it. Magnesium is an essential dietary mineral, and the second most prevalent electrolyte in the human body. Magnesium deficiencies are actually very common in developed countries due to the high amount of grains consumed and lack of nut and vegetable intake. Deficiency can cause high blood pressure and reduced glucose tolerance. The easiest way to supplement Zinc and Magnesium is by taking ZMA before bed which also acts as a sedative, giving you a deeper sleep.

Probiotic - Taking a probiotic is a great way to introduce good bacteria into your digestive system and improve gut health. The benefits to a probiotic are seemingly endless, but to summarize:

Probiotics can typically be taken anytime of the day, depending on the product.

Fish Oil - Fish oil is a great health promoting supplement that is rich in omega-3 fats, EPA and DHA. Omega-3's are essential for a healthy heart, they reduce bad cholesterol (LDL) increase good cholesterol (HDL) and prevent the formation of triglycerides. Another great benefit is reduced inflammation, people with gastrointestinal issues have shown improvements after supplementing with fish oil. A decrease in joint pain and arthritis is also a common positive side effect of fish oil supplementation.


For Performance

Creatine - Creatine Monohydrate is possibly the most studied sports supplement on the planet, over 700 studies, it is incredibly safe and is hugely beneficial. Creatine is a molecule that can rapidly produce energy (ATP), supplementing with it increases power output, work capacity and muscle growth. It has other great benefits as well, such as increasing brain function, bone density and liver health. Creatine can be taken at anytime of the day, it is often found in pre-workouts but creatine has not been shown to have an instant effect. Creatine Monohydrate is the best form of creatine to take, 2-5g a day is suitable for most people depending on bodyweight.

Whey Protein - This is a no brainer, anyone doing any sort of exercise can benefit from supplementing with protein. Whey helps to build muscle, recover from workouts and meet daily protein goals. It is naturally loaded with BCAA's and has many other benefits as well, such as - increase immune function and decrease blood pressure and cholesterol.

Beta-Alanine - Has been shown to enhance muscular endurance, many studies show a multiple rep increase over baseline in the range of 8-15 repetitions. It also increases high intensity cardio performance, such as rowing or sprinting when supplemented.

Caffeine - We all know what Caffeine is, a stimulant that makes us more awake and alert. But did you know it can increase anaerobic endurance and power output?

Lactate (Lactic Acid) -During strenuous exercise, your muscles require more oxygen. When these oxygen requirements can not be met your body reverts to lactic acid (lactate) for energy. Supplementing with lactate means you already have lactate in your blood, your muscles already have the fuel they need.

The burning sensation is greatly reduced, even eliminated, by significantly balancing pH as this study shows. Work capacity increases through the roof, for example, this study showed a 17% increase in time to exhaustion when supplementing with lactate. Read more about lactate in our blog post here.
