Is collagen powder a waste of money?

| NOV 23, 2021

There’s so much misleading information on the web regarding collagen powder, and we know it can make things very confusing. Here we break down some of the biggest myths regarding collagen and what the real benefits are.

Does powdered collagen really do anything?

The anecdotal evidence for taking collagen suggests impressive results for shinier hair, stronger nails, and improved skin elasticity, but what does the latest research tell us?

Although understanding the mechanism of exactly how taking collagen improves hair, skin, and nails is still an emerging field, a rummage through the latest scientific literature reveals some positive findings that back up what we already strongly suspected.

A 2019 review of 19 contemporary studies concluded that taking hydrolysed collagen orally for 90 days improved skin elasticity and hydration and reduced wrinkles, thus improving the signs of ageing.

But how about marine collagen in particular? One study, which specifically used low molecular-weight marine collagen, reported improved skin hydration after six weeks of use and improved wrinkles and elasticity after 12 weeks of use.

Additional studies indicate a benefit for joint pain and osteoarthritis.

Further research is required to evaluate the benefit of taking collagen to improve nail and hair health. Still, the studies mentioned above do indicate that taking collagen has a beneficial effect.

Collagen powder vs pill: is there a difference?

Collagen pills are simply collagen powder in pill form; as long as they are both hydrolysed, the body will break them down in the same way: peptide chains will be absorbed into the bloodstream via the small intestine.

So, in theory, there is no difference in potency, though powdered collagen offers the following benefits:

VERSATILITY: as it is odourless and tasteless, you can add powdered collagen to your coffee, a smoothie, and many other recipes.

FLEXIBILITY: a powder allows you to take exactly the amount you need, as and when you want it: you can add some to your water bottle to sip on through the day.

PURITY: some capsules may contain more fillers and binders than powder to get them into capsule form. Always read the label. 

SIMPLICITY: you may have to take several pills to get the equivalent dose that you would get from one spoonful of powder.

Whether in pill or powder format, not all collagens are of the same quality: Skinful is made from wild, sustainably caught cod skin and is third-party tested for purity.

Collagen Powder Myth Buster

Myth 1: Collagen powder is damaged by heat

Large collagen molecules can be affected by heat but small, hydrolysed peptides (the type you'll find in Skinful ) can withstand heat up to 300°C!  This makes Skinful one of the few protein powders that can be used in hot drinks. 

For those who are interested, here's a cool study to back up this claim.

Myth 2: You need to take 10g of collagen a day

Our manufacturer recommends 5g to 10g a day, and when we first launched Skinful we recommended you take 10g for the first month. After a few months we received lots of feedback from customers and Nutritional Therapists who were seeing the benefits using just 5g. We therefore changed our label and now recommend 5g. 

However, the serving is highly personal depending on health, metabolism, age and many other factors, so it’s best to consult a Nutritional Therapist if you have any specific concerns.


Myth 3: Collagen powder doesn't survive stomach acid

We consulted Nutritional Therapist, Susie Debice BSc Hons, Dip ION, who says:

“When it comes to the bonds between the amino acids in the long peptide chains, most are easily broken by the action of stomach acid. However, one particular amino acid, hydroxyproline, found linked to proline or glycine in a collagen peptide chain, forms incredibly strong bonds that are pretty resistant even to the toughest of proteolytic enzymes. Why is this important? Because the dipeptides and tripeptides containing hydroxyproline get readily absorbed across the small intestine and play a key role in the way your body produces its own collagen."

Skinful is high in these amino acids and we post our full amino acid profile on the Skinful product page.


Based on our own personal experience of taking collagen powder, our product and Trustpilot reviews, and the studies available we think it’s a good investment if you’re in your late twenties or older.  Before then, you probably don’t need it as you have lots of your own collagen.
