Why Go Plant-Based? The Rise of Non-Dairy Supplements

The Shift in Fitness Nutrition

More athletes and gym-goers are turning to non-dairy supplements to support ethical, environmental, and health goals. But aside from lifestyle alignment, plant proteins also bring genuine functional benefits.

Top reasons for going plant-based:

• Lactose intolerance or dairy sensitivity
• Ethical or environmental concerns
• Desire for clean, hypoallergenic ingredients

Common Concerns

• Are plant proteins complete?
• Will I still gain muscle?
• Do they taste good?

Spoiler alert: With the right strategy, plant-based protein powders tick all the boxes.

Understanding Plant-Based Protein Sources

The Major Players

Let’s break down the top sources you’ll find in your favourite vegan protein tubs:

1. Pea Protein

Source: Yellow split peas
Profile: High in BCAAs, especially lysine and arginine
Texture: Creamy, mixes well

2. Brown Rice Protein

Source: Brown rice grains
Profile: Rich in methionine, low in lysine (best in blends)
Texture: Slightly gritty

3. Hemp Protein

Source: Ground hemp seeds
Profile: Complete protein, contains omega-3 fatty acids
Texture: Coarse, earthy flavour

4. Soy Protein

Source: Soybeans
Profile: Complete protein with high digestibility
Note: Avoid if allergic or sensitive to soy

5. Pumpkin Seed, Chia, and Sunflower Proteins

Great in blends for micronutrient boosts
Add texture and natural fats

Are Plant Proteins Complete?

Not always. Some, like soy and hemp, are complete proteins. Others (like rice or peas) lack one or two essential amino acids. That’s why blending proteins is key for muscle support.

How Plant Protein Fuels Muscle Growth

The Science of Muscle Building

Muscle protein synthesis (MPS) relies on amino acids, especially leucine. Whey protein contains high leucine levels, but well-formulated vegan blends can match this.

What You Need to Build Muscle:

• Adequate protein intake (~1.6–2.2g per kg of body weight daily)
• Full amino acid profile
• Strategic timing (post-workout, morning, bedtime)

Look for blends with at least 2.5g of leucine per serving. This is the optimal dose to trigger MPS.

Wrong. With the right amount and quality, vegan protein supports hypertrophy just fine.

Old news. Today’s products offer rich, satisfying flavours.

Myth 3: “You need dairy to grow muscle.”

Nope. Research shows equivalent gains with well-planned vegan diets.
