Heavy Metals In Marine Collagen: Why Sourcing Matters

As conversations around supplement safety continue to grow, more consumers are asking important questions about heavy metals — and rightly so.

At BY BETH, transparency and trust are at the centre of everything we do. That’s why we test our products for heavy metals and are proud to say our products showed no detectable levels within testing standards.

Because when it comes to wellness, safety should never be assumed.

What Are Heavy Metals?

Heavy metals are naturally occurring elements that can sometimes contaminate food, soil, water, and supplements through environmental exposure or manufacturing processes.

Common heavy metals consumers are often concerned about include:

• Lead

• Mercury

• Cadmium

• Arsenic

While trace environmental exposure exists across many industries, the quality of sourcing, farming, manufacturing, and testing standards plays a significant role in product safety.

Why Heavy Metals Have Become A Concern In Supplements

The supplement industry is largely unregulated in many parts of the world, and not all brands conduct rigorous testing on raw ingredients or finished products.

Some products on the market may contain contaminants due to:

• Poor sourcing practices

• Contaminated soil or water

• Low-quality manufacturing

• Inadequate testing protocols

Unfortunately, consumers are rarely given full visibility into these processes.

That’s why independent testing and transparency matter.

Why Source Matters — Especially With Marine Collagen

Not all collagen is created equally, and one of the biggest differences comes down to sourcing.

Many marine collagen products on the market are sourced from large-scale overseas fish farming operations, particularly across parts of Asia where farming and manufacturing regulations can vary significantly between suppliers.

Because fish can absorb contaminants from their surrounding environment, marine collagen may carry a higher risk of contamination if sourcing and testing standards are not carefully controlled.

This is one reason heavy metals have become an increasing concern within parts of the collagen industry.

At BY BETH, we take a different approach.

We prioritise high-quality sourcing, strict manufacturing standards, and product testing because consumers deserve confidence in what they’re putting into their bodies daily.

Rather than relying on low-cost mass sourcing, we focus on transparency, safety, and quality control at every stage of production.

Our Commitment To Testing

At BY BETH, we take ingredient safety seriously.

Our products undergo testing to ensure they meet strict quality and safety standards, including screening for heavy metals.

Our testing showed no detectable heavy metals within standard testing parameters.

This is an important part of our commitment to creating products women can feel confident using daily.

Why We Prioritise Australian Sourcing

One of the biggest factors influencing supplement purity is ingredient sourcing.

That’s why we prioritise Australian suppliers and high-quality farming practices wherever possible.

Clean sourcing, responsible manufacturing, and rigorous quality control all contribute to safer, cleaner products.

This is also why we avoid cutting corners with cheap bulk ingredients sourced purely for lower costs.

Transparency Over Fear Marketing

Heavy metals have become a major talking point online, and while awareness is important, we also believe consumers deserve balanced, factual information rather than fear-based marketing.

Our goal is not to create panic.

Our goal is to create trust through transparency.

We believe wellness brands should openly discuss:

• Testing standards

• Ingredient sourcing

• Manufacturing quality

• Product integrity

Because consumers deserve clarity around what they’re putting into their bodies.

Clean Wellness Starts With Trust

At BY BETH, clean wellness goes beyond what’s included in a formula.

It’s about the standards behind every decision:

• Thoughtful sourcing

• Rigorous testing

• Transparent communication

• Honest education

We created BY BETH to simplify wellness and help women make more informed, confident choices about their health.

And that starts with products you can trust.
