Proprietary Blends: What Supplement Companies Don’t Want You to Know

If you've ever flipped over a supplement bottle, you've probably seen something like this on the label:

Proprietary Blend – 1,000 mg Ingredient A, Ingredient B, Ingredient C

At first glance, it might seem like you’re getting a powerful mix of multiple beneficial ingredients. But here’s the truth: proprietary blends can be one of the most misleading practices in the supplement industry.

Let’s break down why.

⚠️ What Is a Proprietary Blend?

A proprietary blend is a group of ingredients listed under a single combined dose, without disclosing how much of each ingredient is actually included. Supplement manufacturers use it to protect their "secret formulas"—but it often ends up protecting profit margins more than consumers.

😬 Why It Can Be Misleading

Imagine a blend that lists three ingredients:

• Caffeine

• Green tea extract

• Rhodiola rosea

You assume you’re getting a balanced mix. But under FDA regulations, companies only need to list ingredients in order of predominance—not in specific amounts. So this blend could easily be:

• 990 mg caffeine

• 5 mg green tea extract

• 5 mg rhodiola

That’s 99% caffeine—far from the “synergistic herbal energy blend” you thought you were getting.

🧪 Why Doses Matter

Knowing what is in your supplement is only half the story. Knowing how much is essential.

• Clinical effectiveness: Many ingredients only work at specific doses. For example, studies show Rhodiola rosea needs at least 200–400 mg to have noticeable effects on stress or fatigue. If you’re getting 5 mg, it’s doing virtually nothing.

• Safety: Some ingredients can be harmful at high doses—especially stimulants. If you don’t know the exact dose, you can’t judge if it’s safe to combine with other supplements or medications.

• Interactions: Without knowing exact amounts, it’s hard to evaluate potential side effects or how one supplement might interact with another.

💸 The Real Reason for Proprietary Blends

In many cases, proprietary blends are used to:

• Hide cheap formulations

• Underdose expensive ingredients

• Rely on one high-impact ingredient (like caffeine) while making it look like a diverse formula

• Avoid scrutiny from consumers who know what proper dosing looks like

This can lead to products that are:

• Ineffective

• Overpriced

• Unsafe (especially if you stack products with overlapping blends)

✅ What to Look For Instead

To make smarter supplement choices, look for products that:

• List every ingredient with its exact dose

• Reference clinical research or provide transparency around formulation

• Avoid “proprietary blends” altogether

• Are third-party tested for purity and potency

Final Thoughts

Proprietary blends might sound high-tech or exclusive, but they often keep you in the dark. If a company doesn’t tell you how much of each ingredient you’re getting, ask yourself: what are they hiding?

Transparency isn’t just about trust—it’s about your health. Whether you’re an athlete, a student, or just trying to feel better day-to-day, knowing what you're putting in your body—and how much—should never be optional.

Pro tip: When in doubt, skip the blend and go for single-ingredient supplements where dosing is clear. Better results, fewer surprises.
