Listen On:
The Truth About Collagen, Supplements & What’s Actually Worth Taking
(And why most products aren’t doing what you think they are)
If you’ve ever stood in the supplement aisle, turned a bottle around, squinted at the label… and still walked away thinking “I have no idea if this is doing anything” this episode is for you.
Because let’s be honest: the supplement industry is loud. Buzzwords everywhere. Big promises. Very little transparency.
In this episode of the podcast, I sit down with Rose Rayner, founder of Calmerceuticals, to pull back the curtain on the ingestible beauty industry and trust me, once you hear this conversation, you’ll never read a supplement label the same way again.
Why Most Supplements Don’t Work
Here’s the uncomfortable truth:
A huge percentage of supermarket and pharmacy supplements are underdosed, poorly absorbed, or packed with fillers that do absolutely nothing for your body (and in some cases, can do more harm than good).
Rose breaks down exactly why:
-
Many products use token doses just so they can list an ingredient on the label
-
Fillers and bulking agents often replace what actually matters
-
“Clinical strength” doesn’t always mean clinically effective
If you’ve been taking supplements consistently with zero results… it’s probably not you. It’s the product.
Collagen: The Dose That Actually Makes a Difference
Collagen is everywhere right now but here’s what most brands won’t tell you:
👉 3g vs 10g of collagen is a HUGE difference.
And yes, it absolutely impacts whether you see changes in:
-
Skin elasticity
-
Fine lines
-
Hair thickness
-
Nail strength
-
Joint health
Rose explains the exact collagen dose needed to stimulate real change in the body — and why most products fall dramatically short.
🧬 What “Bioavailability” Really Means
You’ll hear this word everywhere… but what does it actually mean?
In simple terms:
It doesn’t matter how much of something you take — it matters how much your body can absorb and use.
In this episode, we unpack:
-
Why some forms of vitamins are basically useless
-
How fermentation and prebiotic fibres change absorption
-
Why vitamin C isn’t just an “add-on” — it’s essential
This is the difference between expensive urine and actual results.
🧪 Fillers, Hidden Ingredients & Marketing Tricks
One of the biggest eye-openers?
The fillers and hidden ingredients that sneak into supplements under names you’d never think twice about.
Rose shares:
-
Ingredients you should always avoid
-
How to spot low-quality formulations instantly
-
The red flags that scream “this is just good marketing”
Once you know what to look for, you can’t unsee it.
👩⚕️ Why Women Need to Pay Attention to Testosterone
This might surprise you — but testosterone isn’t just a “male hormone”.
As women age, declining testosterone can impact:
-
Energy
-
Muscle tone
-
Mood
-
Libido
-
Skin quality
We talk honestly about why this matters, why it’s often overlooked, and how supporting your body properly makes a real difference long-term.
⏳ How Long Does Collagen Actually Take to Work?
If you’re expecting overnight miracles… this part is important.
Rose explains:
-
When you can realistically expect to see results
-
Why consistency matters more than trends
-
What changes show up first (and which take longer)
Spoiler: real results take time but when the dose and formulation are right, they do happen.
