How to increase protein intake as a vegan

Veganism is soaring in popularity. Celebrities, the media, and documentaries are all talking about it; it's been impossible for us to ignore! And despite many of the benefits of veganism, one of the challenges for vegans has been consuming an adequate amount of protein in line with scientific recommendations. This article will detail why vegans can struggle to consume enough protein and provide a practical approach with specific foods and supplements to ensure protein requirements can be met.

Why Vegans battle to get enough protein

Vegan or omnivore, you'll need 1.7 grams - 2.6 grams of protein per kilogram of body weight per day for optimal muscle growth.

Vegans tend to struggle to consume enough protein because plant-based foods are simply lower in protein when compared to an omnivorous diet. Making it even harder is the fact that vegans consume less energy than their omnivore friends, so the chances of getting more protein obviously decreases.

Vegans mustn't focus just on the amount of protein they get, but the quality of it to recover and grow from resistance training and exercise. Moreover, with protein being important for satiety and thus fat loss, it's critical to have a solid plan in place.

Another hurdle for vegans to overcome is that plant-based protein sources are often incomplete; an incomplete source of protein does not contain all essential amino acids. A complete protein source (found significantly more in an omnivorous diet) contains all nine essential amino acids in the right proportion to build protein in the body. We're talking about foods like beef, chicken and fish, for example.

And the key point is this: one of the vital amino acids that vegans can miss out on is leucine, one of three branched-chain amino acids (BCAAs).

Vegans can struggle to get enough protein and leucine.

Getting enough leucine in your diet: How to grow muscle as a vegan

You might have heard people claiming that's it's harder to build muscle as a vegan. Whilst this is a challenge because of leucine, it can be overcome. Leucine is so important because it's what triggers muscle growth and helps us recover and adapt from exercise. Think of it as one of the critical keys that unlock the muscle growth door when you've finished training!

Omnivores have the luxury of simply eating their required protein numbers and thus getting enough leucine as a result. But for vegans, it's much harder than that, and they tend to be advised to eat even more protein than is recommended to ensure they get enough leucine.

So how much leucine do vegans need? Well, for anyone that doesn't exercise, the daily dosage of leucine is about 40-45 mg per kilogram of body weight per day, which works out to be about 3.6 grams of leucine daily for someone who weighs 80 kilograms. And for those of us who exercise, precise dosages are yet to be declared, so we'll stick to the higher end to be safe.

Foods high in protein and leucine: Growing muscle on a vegan diet

The first strategy for vegans to ensure they eat enough protein and thus leucine is by eating foods high in both. Here are some examples below:

FoodProtein per 100g
Pumpkin seeds (dried, uncooked)30.2
Lentils (red, split, uncooked)24.6
Black beans (uncooked)21.6
Almonds (raw)21.2
Tofu (calcium set)17.3
Oats (rolled)16.9
Quinoa (uncooked)14.1

Moreover, other foods like peas, potatoes, peanuts, walnuts and pistachios will really help vegans reach adequate protein levels.

Vegan supplements: BCAAs for muscle growth

With our Bulk Nutrients BCAA Recovery obviously containing leucine, and a generous 5 grams a serve, it makes BCAAs a great supplement for vegan gym-goers. Moreover, a serving of our BCAAs contains 11 grams of protein.

BCAAs can be taken anywhere and at any time too, which makes them very convenient when we're on the go.

Our BCAA Recovery contains 11 grams of protein and 5 grams of leucine per serve.

Vegan supplements: Bulk Nutrients Future Whey for muscle growth

The third option for getting enough protein and leucine is by consuming our Future Whey protein powder. Future whey comes in great flavours like berry, cola, and lemonade, and contains 3.4 grams of leucine, including all essential amino acids -- and 22 grams of protein!

So now you know the foods and two critical supplements that can help vegans get enough protein and leucine, but how can we go about putting all that together?

Our Future Whey contains 3.4 grams of leucine and 22 grams of protein in a single serve.

Muscle building diet plan for Vegan fitness fanatics and bodybuilders

Here is a sample day of how vegans can get adequate levels of protein and leucine, using the hypothetical example of Bulk Nutrients customer "Christina" who weighs 65 kilograms and is looking to gain muscle mass.

Christina burns 1800 calories a day and therefore needs to eat in a 20% calorie surplus for muscle growth: 2160 calories. Broken down into macronutrients, Christina would need to eat the following:

Protein: 167 grams (668 calories).

Fat: 50 grams (450 calories)

Carbohydrates: 260 grams (1040 calories)

Leucine requirements = not declared by science for those looking to gain muscle at this stage, but let's aim for 7 grams to be safe!

Total: 2158 calories.


1 serving of Bulk Nutrients Future Whey

3 slices of bread (white or brown) with a 40 g serving of strawberry jam

Protein = 28 grams, Fat = 8 grams, carbohydrates = 80 grams (Leucine: 3.4 grams)


200 grams of tempeh

100 grams of cooked lentils

2 cups of spinach

Protein = 49 grams, Fat = 10 grams, carbohydrates = 42 grams (Leucine: 2.1 grams)

Tempeh and tofu: great protein sources for vegans that are also high in leucine.

200 grams of Tofu (calcium set)

2 cups of quinoa (cooked)

1 cup of broccoli

Protein = 50 grams, Fat = 17 grams, carbohydrates = 89 grams (Leucine: 3.1 grams)

Before bed snack:

5 pikelets

22 grams of peanut butter

1 and a half servings of Bulk Nutrients Future Whey

Protein = 35 grams, Fat = 15 grams, carbohydrates = 50 grams (Leucine: 5 grams)

GRAND TOTAL: Protein = 162 grams, Fat = 50 grams, carbohydrates = 261 grams (Leucine: 13.6 grams)

You can see how Christina has been able to get adequate protein, and leucine, utilising Bulk Nutrients supplements and good quality foods.

But of course, this is the perfect scenario where Christina has had time to prepare and plan foods. But when this isn't the case, Christina can rely more on her BCAAs and Future Whey to reach adequate leucine and protein numbers. The reality is that a BCAA and protein supplement can generally guarantee with ease that vegans will achieve adequate levels of protein and leucine when life gets busy.

The bottom line is that with enough planning and supplements, vegans can still reach sufficient nutritional requirements to grow muscle at the same rate as their omnivore friends!
