is it safe to take, what is the best form and what are the benefits?

At first, each influencer, affiliated physician and neighbourhood ‘that lady’ was spruiking the advantages of this little identified complement. It flew off the cabinets.

Then, slugging a blow to the collagen growth was was Dr Karl, completely debunking the premise of collagen. Unexpectedly it appeared ridiculous we’d been slurping these powders for actually no purpose.

But, the anecdotal proof from family and friends, speaks for itself. If somebody who takes collagen, you will have heard them rave about the advantages. However, then once more, is it simply the placebo impact?

Like what you see? Signal as much as our bodyandsoul.com.au newsletter for extra tales like this.

We determined to take it upon ourselves to resolve what is admittedly occurring on the earth of collagen by speaking to not one, not two, however three pores and skin medical doctors.

What we learnt?

By this stage within the collagen complement evolution you’d assume there could be a wealth of dependable scientific proof, given that everybody appears to be taking it. Sadly, it isn’t as complete as we would like.

1. What’s Collagen? Why is it categorised as a protein, how is it fashioned and why is it vital to our our bodies?

“Collagen is a protein that helps make up the scaffolding and help buildings of many tissues inside our physique together with the pores and skin,” explains Dr Deshan Sebaratnam, dermatologist and Senior Lecturer at UNSW.

He says that some collagens are inflexible and others extra versatile. Pores and skin scientist and founding father of Qr8 and Qr8 MediSkin, Dr Michele Squire, provides that it makes up round 30% of our complete protein mass. It may be discovered within the pores and skin, but additionally bones, ligaments, tendons, cartilage, muscle, blood vessels, inner organs and the cornea.

Now, let’s give attention to its use for the pores and skin.

Collagen sits within the dermis the place, “along with different proteins like elastin and hyaluronic acid, it kinds the extracellular matrix (ECM). This supporting meshwork construction provides pores and skin its power and resilience (and bounce!),” explains Dr Squire. “Collagen is the foremost ECM part, making up round 75% of the pores and skin’s dry weight.”

She provides that as we age, collagen provide isn’t replenished as shortly, and mixed with different elements can result in sagging, much less elastic pores and skin and wrinkles.

“Collagen depletion begins to occur in our 20s, growing to 1% loss annually after 40, with 75% general collagen loss by our 80s. Publicity to the solar’s UV radiation and pollution like cigarette smoke improve enzymes that degrade collagen additional, enhancing these indicators of ageing.”

2. Do collagen dietary supplements for the pores and skin really work?

You would possibly marvel how this powder you eat magically makes its strategy to your pores and skin, bypassing all the opposite collagen places in your physique.

“The analysis on oral collagen dietary supplements continues to be in its infancy. One faculty of thought is that collagen dietary supplements are damaged down within the digestive tract to smaller elements which could then be utilized by fibroblast [cells] to assemble collagen inside the pores and skin,” explains Dr Sebaratnam. “Another theory is that the damaged down collagen would possibly act as a sign to the pores and skin to stimulate synthesis of structural constructing blocks like hyaluronic acid.”

Dr Squire agrees that extra analysis must be accomplished, saying that of the greater than 6,000 research accomplished on the dietary supplements there are simply 19 current high-quality ones performed on 1,125 human topics for the sector of dermatology.

She says these present early proof that collagen can stimulate collagen, elastic and hyaluronic acid manufacturing within the pores and skin – which is understood to assist with wrinkles, hydration and elasticity.

Michelle Wong lately put out a video on this very matter, debunking the anti-collagen science spruiked by Dr Karl.

Dr Karl:

Michelle Wong:

She says that it’s a standard false impression that collagen will work the identical as some other protein.

It is true that the protein breaks down into particular person amino acids within the digestive system and that after this occurs the particular proteins cannot be distinguished (like breaking apart phrases into particular person letters so you may’t inform what it spells anymore).

However…

“Collagen comprises a comparatively distinctive amino acid known as hydroxyproline. So after digestion and absorption, your physique can doubtlessly reply otherwise in comparison with different proteins, and there is proof that very small collagen fragments find yourself in your blood after you’re taking a collagen complement, and may doubtlessly sign to your physique to make extra collagen.”

It is nonetheless early doorways on this analysis although.

“There are some scientific trials with promising outcomes. Nevertheless, the proof for collagen dietary supplements continues to be fairly weak in comparison with tried and examined methods of boosting and preserving your pores and skin’s collagen, equivalent to sporting sunscreen, and utilizing anti-aging skincare elements like tretinoin, retinol and vitamin C,” she continues. “Collagen dietary supplements are additionally tough as a result of there are lots of totally different variations which do not essentially have the identical results in pores and skin, and only a few variations have been examined independently.”

Dr Sebaratnam is cautious of recommending it, regardless of the few promising research, as “there is not any robust proof that one type of collagen supplementation is healthier than others. I would not endorse anybody take it except scientific proof turns into extra conclusive.”

3. Is it protected to take a collagen complement? If that’s the case – who ought to take it, how a lot and what unintended effects ought to they count on?

“A recent meta-analysis combining proof from plenty of small research appears to indicate some weak proof in favour of anti-aging properties of oral collagen dietary supplements. On this paper there have been no opposed results of collagen supplementation recognized…. besides to your purse if in a couple of years we uncover that it is not significantly useful,’ Dr Sebaratnam says.

Dr Squire provides that these with seafood allergic reactions would possibly think about steering away from marine collagen particularly.

For Michelle Wong, because of lack of regulation within the sector “it’s tough to ensure security with dietary supplements.”

What for those who do determine to take collagen?

“There are such a lot of collagen dietary supplements obtainable, and dosage isn’t standardised – you’ll need to learn the dietary info panel on the label to see how a lot collagen your product comprises so as to take an efficient dose,’ says Dr Squire.

“To information your dosing, topics in scientific trials ingested 2.5-10g/day of low molecular-weight collagen peptides for a minimum of 12 weeks earlier than outcomes have been measured. Outcomes needs to be evident by 3 months, though could also be obvious earlier, relying on the dose, high quality of the complement and the pores and skin’s personal collagen necessities.”

She provides that whereas collagen dietary supplements could also be an addition to your skincare routine, they aren’t the ‘silver bullet simply by themselves (don’t purchase into that hype!).’

“Collagen dietary supplements work finest when mixed with nice topical skincare, solar safety, and weight-reduction plan wealthy in amino acids and important co-factors for collagen synthesis equivalent to vitamin C, iron, zinc, and copper (these embrace: lean meat, fish, egg whites, nuts and seeds, fruit (particularly citrus) and leafy inexperienced greens). If in case you have uncared for your pores and skin, or have extreme solar injury, collagen dietary supplements gained’t produce miracles alone.”

4. What’s the finest type of collagen: vegan/marine/bovine. Does it matter the way it’s formulated i.e. tablets, gummies, powder.

All of our specialists consider this query requires much more analysis and regulation within the trade. Nevertheless, Michelle Wong did point out that regardless of the variation it is very important have a look at how they’re hydrolysed.

“Collagen dietary supplements are often hydrolysed, which implies they’re damaged up, and they are often damaged up in some ways,” she says.

Dr Squire additionally touched on the best way it’s damaged down, saying that “totally different processing strategies can lead to very totally different collagen purity, focus, peptide dimension and amino acid composition. Which means that high quality and dose can fluctuate enormously between manufacturers.”

Her suggestions are to search for:

• Extremely purified collagen from a sustainable supply
• A excessive focus product
• Low molecular weight peptides for optimum absorption (between 2-4 Kilodaltons).
• Excessive concentrations of the amino acids proline and hydroxyproline

Lastly…

“‘Vegan’ collagen isn’t really a factor in dietary supplements, so don’t be fooled. Collagen is just an animal by-product. Some other ingredient or set of elements, even when labelled ‘collagen’ or ‘vegan collagen’, isn’t really the identical molecular construction as collagen – particularly if it comes from a plant supply.”

5. How can we get collagen from meals naturally? Are there any practices that may naturally stimulate collagen i.e. dermarolling/gua sha?

Dr Deshan Sebaratnam recommends utilizing a broad spectrum sunscreen as among the best evidence-based practices to assist defend your collagen provide, in addition to not smoking.

“Actives equivalent to vitamin C and niacinamide may also help, as can retinoids which exist on a spectrum of strengths from over-the-counter to prescription solely formulations. Power primarily based procedures equivalent to fractionated radiofrequency, fractionated laser and intense pulsed light can all assist promote collagen manufacturing.

Dr Squire agrees however suggests we don’t depend on at-home variations.

“There are a number {of professional} collagen induction therapies (e.g. some lights and lasers, microneedling) however with at-home derma rollers, microcurrent units, LED lights and different therapeutic massage instruments, there’s no good high quality proof that these stimulate collagen (save your cash on these sorts of instruments!).”

“In the event you’re in search of topical merchandise to extend collagen manufacturing, prescription retinoids are the gold normal.”

However what about in meals?

“Many individuals assume you may get sufficient collagen out of your weight-reduction plan, or by consuming gelatin or bone broth. However the quantity of bioavailable collagen peptides from dietary sources is extremely variable – it is determined by the animal, what physique half it’s from, how a lot you eat, and the way it was cooked,” says Dr Squire.

“Even ready bone broth, thought-about essentially the most superior dietary collagen supply, has a big variation between amino acid content material relying on how it’s ready. And with all the most effective intentions, none of us eat a 100% nutritious diet day by day, and we might not take up all of the vitamins optimally both, particularly as we age. So dietary collagen is an unreliable supply, geared extra in the direction of fundamental dietary adequacy, somewhat than optimum pores and skin well being.”

Michelle Wong agrees, “There’s some very preliminary proof that collagen from meals would not essentially work in addition to hydrolysed collagen from dietary supplements, for the reason that dietary supplements are damaged down extra effectively than in our digestive techniques.”
