Vegan Protein for Bodybuilding – Why it Makes Sense for building muscle

Why Many are turning to non-dairy options like Vegan Protein for Bodybuilding

Protein intake continues to change as gut health starts to take priority. Gut health has become a priority for athletes and bodybuilding diets. Most of us imagine a series of meat focused meals, such as steak for breakfast, bowls of chicken and rice throughout the day, and huge whey protein tubs filling up the pantry. Despite what many experts now believe a strictly meat based protein diet can achieve, a vegan protein diet is a legitimate way to build quality muscle mass while balancing your gut health. That is why today we see many strength athletes and bodybuilders switching to a cleaner way of eating, enabling them to perform their best with natural and non-dairy based protein powders.

Are Vegan Proteins Effective?

The proof is in the tub; it is absolutely possible to build muscle on a vegan diet, and vegan bodybuilding is becoming increasingly popular. The principles are the same; you need to eat the right amount of calories with the right macronutrient balances. If you do that with a plant-based diet, you may find that you have more energy, you recover quicker, and you are ready to tackle new challenges.

All that being said, if you are a vegan bodybuilder, then it becomes even more important to supplement with a vegan protein, as vegan foods do not always have enough protein in them. An extra protein boost that your body can easily absorb could be essential to your vegan diet, especially after working out. What are you waiting for? Ditch out the whey for pea and rice protein. If you are looking for a quality, all-natural product, we recommend Nutricost Pea Protein.

Benefits of Vegan Bodybuilding

There are increasing health concerns about dairy consumption, including its implications on heart health, digestive health, and even the likelihood that someone develops cancer. There also has been some evidence-based research has also shown that contrary to what the dairy industry has been telling us, it has little to no effect on bone health.

Reduction of Digestive Stress

Dairy is a source of digestive stress for many people, for the simple reason that we are not made to consume it. Milk can be pumped full of growth hormones and fat, meant for a baby calf, and most humans would fair better if they cut it out of their diet.

Many whey and casein protein powders result in unexpected side effects such as feeling bloated, gassy, and low on energy. If you are bulking up, then you need a protein supplement to reach your peak performance. However, it is important to have one that is easy to digest and allergen-free.

Diet Diversity

Getting proteins from a vegan diet means a wide variety of nutrition. Vegan protein contains beneficial vitamins and minerals, fiber, fatty acids, and a range of probiotics. Most high-quality vegan powders are also organic, non-GMO, soy-free, and gluten-free.

On the other hand, meat and dairy can contain harmful chemicals and antibiotics unless you can commit to a strict grass-fed meat diet, which is very expensive!

Health Benefits

So long as you reach your macros and consume a healthy vegan diet with sufficient protein, you should notice more energy, less inflammation and pain, and quicker recovery. One study comparing vegan and omnivore gut-microbiota showed that vegans had fewer pathobionts and a greater abundance of protective species as well as reduced levels of inflammation. (1)

Environmentally-Friendly

Vegan bodybuilding is also more sustainable and ethical. Production of vegan protein uses less water, fuel, and land than animal protein. (2)

Whey Protein Vs. Vegan Protein

Whey protein is an animal protein derived from milk, it is widely accessible, and you can find plenty of cheap products in a wide range of flavors. Whey contains branched-chain amino acids (BCAAs) such as isoleucine, leucine, and valine, building blocks of muscle. The bioavailability of these amino acids is optimum for protein synthesis and enables faster muscle building, leading to muscle mass gain.

This is great if you don’t suffer any of the nasty side effects of whey, such as gas, diarrhea, and bloating. And while there are many great flavors available, this is usually because of artificial sweeteners that are often harmful. They are usually heavily processed, which depletes the nutritional quality, especially in cheaper products. This, paired with the dairy industry’s devastating effects, has left many people looking for alternatives.

Plant-based protein such as pea, hemp, soy, and brown rice are great alternatives. A clinical study in 2013 showed that brown rice protein was equal to whey when measuring strength gain, and recovery. (3) They are much less likely to cause negative side effects and are often created with more natural ingredients.

Whey has a complete profile of amino acids, whereas plant-based proteins can be lacking. No one plant can give the same nutrition as meat. As such, the variety is required. However, protein powders containing both pea and brown rice proteins will provide you will all of the amino acids found in whey, which makes vegan bodybuilding possible.

How to Make Sure You Get Enough Protein Being Vegan

Whether you are eating meat or not, your protein intake should be the same if you want to bulk up and put some quality size on. Although the amount of protein you need depends on how active you are, your individual muscle mass and body weight, and your health and fitness goals. On average, you need around 0.8 grams of protein per pound of lean body mass. (4). If you really want to see gains, it is a good idea to create a meal plan to ensure that you are getting enough protein throughout the day.

It is difficult to succeed at weight loss and, at the same time, gain muscle. Most bodybuilders will first gain weight and then cut down while easing enough protein to retain muscle. If you are trying to gain bodyweight without animal-based products, you will need to eat a lot to get enough calories. It is also a good idea to take a vitamin B12 supplement, as vegans are often deficient and it has many benefits.

On average, you could be aiming for around 25 grams of protein per meal, and your macronutrient percentages should include around 25-30% calories from protein. This is easily accomplished with animal products, but for vegan bodybuilders, this can pose problems. Although there are plenty of protein sources in vegan foods (oats, lentils, beans), they tend to be carb-heavy. This means it is difficult to get the macros optimal for vegan bodybuilding.

There is also debate on the bioavailability of vegan protein (how well your body absorbs it compared to meat protein.) Including plenty of fruits and vegetables into your diet can help your body to absorb protein. Green foods like broccoli and spinach are particularly effective. To be a high protein vegan, it is a good idea to supplement your meal plan with a plant-based protein source to maximize muscle. This helps you avoid the carb-heavy downsides of other vegan protein supplements while still maximizing your muscle without eating meat.

We wouldn’t talk about vegan protein without recommending a good vegan protein powder to help your gains. That being said, Transparent Labs Organic Vegan is our favorite option when it comes to this, check out why.
