The Truth About Proprietary Blends

If you’ve ever flipped a supplement bottle around and stared at the label, you may have noticed something suspicious a section called “proprietary blend.” It sounds science-y, maybe even powerful. But what does it actually mean?

Here’s the uncomfortable truth proprietary blends often hide the exact dosages of ingredients, leaving you in the dark about what you’re really consuming. In a multi-billion-pound industry where marketing often trumps transparency, it’s essential to know what you’re paying for—and putting in your body.

In this blog post, we’ll explore what proprietary blends are, why they matter, and how to choose supplements you can trust. Whether you’re a seasoned lifter or just starting your fitness journey, this guide empowers you with the facts behind the formulas.

What Is a Proprietary Blend?

A Glossy Label with Hidden Details

A proprietary blend is a group of ingredients listed under a single combined weight without disclosing the amount of each component.

Proprietary Performance Blend: 3,000mg

• L-Arginine
• Beta-Alanine
• Creatine Monohydrate.

This means the entire blend weighs 3,000mg, but the label doesn’t specify how much of each ingredient is in there.

Why Companies Use Them

• “Trade secret” protection: To guard their unique formulas
• Marketing illusion: To include trendy ingredients without effective doses
• Cost-cutting: Cheaper filler ingredients can bulk up the blend

Why It Matters for You

Without knowing the actual dosages, you can’t:

• Assess effectiveness
• Compare products accurately
• Avoid potential overdoses or underdosing

Bottom Line: You wouldn’t buy a car without knowing what’s under the hood. Don’t do the same with your supplements.

Common Pitfalls of Proprietary Blends

1. Underdosed Actives

Many supplements include scientifically supported ingredients, but in amounts far too low to be effective.

• Creatine Monohydrate is effective at 3–5g per day. But in a proprietary blend? You might get just 500mg.
• Beta-Alanine needs at least 3.2g/day for performance. You might get half that, or less.

2. Filler Ingredients

Cheaper ingredients like maltodextrin, taurine, or glycine often bulk up blends.

• Adds little to no value
• Inflates the total weight deceptively

3. All Show, No Substance

Some blends list a dozen trendy ingredients to appear “advanced.”

• Sounds impressive,e but lacks clinical relevance
• Quantity trumps quality on paper

Consumer Insight: Transparency is power. If you can’t verify the dose, you can’t trust the product.

How to Decode Labels

Transparent vs. Proprietary

Look for supplements that list individual ingredient amounts clearly:

• Beta-Alanine – 3,200mg
• L-Citrulline Malate 2:1 – 6,000mg

Compare that to:Performance Matrix- 8,000mg
— L-Citrulline, Beta-Alanine, L-Tyrosine

You get more control and confidence with the former.

Clinical Dosage Benchmarks

Familiarise yourself with evidence-based dosages for common ingredients:

• Examine.com
• PubMed
• Labdoor

Knowing what to look for helps you:

• Spot underdosed products
• Avoid unnecessary add-ons

Red Flags to Avoid

• Vague names like “pump matrix” or “strength complex”
• Too many ingredients (more than 10 is often excessive)
• No third-party testing or quality assurance

Tip: When in doubt, Google the blend name + “clinical dose.”

Case Study: Pre-Workout Showdown

Brand A: Proprietary Blend Pre-Workout

• Total blend: 5,000mg
• Ingredients: L-Citrulline, Beta-Alanine, Caffeine, Taurine, Arginine Alpha-Ketoglutarate

• L-Citrulline Malate: 6,000mg
• Beta-Alanine: 3,200mg
• Caffeine: 200mg
