Which One Ought to You Purchase? – SET FOR SET

Collagen is likely one of the most generally mentioned dietary supplements within the wellness and sweetness industries at present. It exhibits up in powders, capsules, lotions, and even espresso creamers. However as quickly as you begin buying, you will discover two phrases that may be complicated: collagen and collagen peptides. Are they the identical factor? Is one higher than the opposite? Let’s break it down step-by-step in easy language.

What Precisely Is Collagen?

Collagen is probably the most plentiful protein within the human physique. It makes up a couple of third of all protein in your physique and is a key element of; 

• Your pores and skin
• Bones
• Tendons
• Cartilage and connective tissues

It helps to type robust connective tissue, but barely “stretchy”, permitting it to carry buildings collectively whereas permitting some motion. Whereas your physique can naturally produce collagen, manufacturing can decelerate as you age. This drop is why; 

• Wrinkles type
• Pores and skin will get thinner
• Joints might really feel stiffer with time

In consequence, many individuals flip to dietary supplements to extend their collagen consumption.

The Amino Acid Profile Of Collagen

What distinguishes collagen protein from whey protein, soy protein, or collagen protein? This is all associated to the protein’s amino acid composition.

All animal proteins, and several other plant proteins, are wealthy in important amino acids (EAAs), that are primarily liable for muscle development. Collagen differs as a result of it is comparatively low in EAAs, making it a poor alternative for muscle development.

Nevertheless, it stands out resulting from its very excessive focus of glycine, proline, and Hydroxyproline. These three amino acids make up practically half of collagen’s construction and permit it to type its very distinctive form: the triple helix. It additionally boasts excessive concentrations of a number of different vital amino acids.

• Glycine (~33%) – probably the most plentiful amino acid in collagen; important for constructing connective tissue and forming the triple helix construction of collagen.
• Proline & Hydroxyproline (~22%) – present power and stability to collagen fibers. Hydroxyproline is nearly distinctive to collagen, as its existence is far rarer in different compounds. It is used as a organic marker of collagen turnover.
• Alanine – contributes to vitality provide in muscle and helps stabilize protein buildings.
• Arginine & Glutamine – help tissue restore, wound therapeutic, and immune perform.

This is what makes it distinctive on the planet of protein. It isn’t superb for muscle protein synthesis, however it’s claimed to be wonderful for supporting pores and skin, joints, tendons, and connective tissue.

Collagen Protein vs. Collagen Peptides: What Are They?

To grasp the distinction between collagen and collagen peptides, you first must know the way proteins work.

• Protein is a big, complicated molecule made up of chains of amino acids (the constructing blocks of protein). Proteins are like lengthy strings folded into particular shapes.
• Peptides are merely a smaller chain of amino acids. If protein is an extended paragraph, peptides are quick phrases.

If you devour protein, your digestive system naturally breaks it down into smaller peptides and particular person amino acids, permitting your physique to soak up and make the most of them.

Protein → Polypeptide → Peptide → Amino Acid

All of them encompass the identical major compound, amino acids. The one distinction is what number of they’ve.

Collagen vs Collagen Peptides: How Are They Completely different?

Now that we perceive how their buildings have an effect on the terminology, let’s dig somewhat deeper.

• Collagen (typically known as native collagen) is the full, intact protein. It is a really massive and powerful construction. Whereas it gives construction within the physique, it is tougher to interrupt down and take up when eaten in its pure type.
• Collagen peptides (additionally known as hydrolyzed collagen) are collagen proteins which have already been damaged down into smaller items by way of a course of known as hydrolysis. These items are simpler in your physique to digest and take up (Virgilio et al., 2024).

Due to this fact, collagen peptides are merely a “pre-digested” type of collagen, just like whey protein hydrolysate (WPH). WPH is whey protein that has been “pre-digested” and partially damaged down (hydrolyzed) into smaller peptides by way of enzymes.

It is essential to notice that until particularly famous, hydrolyzed collagen peptides encompass the identical amino acids as pure collagen. Nevertheless, some merchandise might enrich their merchandise with the triple helix.

Why Collagen Peptides Are Common

Collagen peptides have develop into the usual type present in most dietary supplements for just a few causes:

1. Higher Absorption. Since peptides are smaller, your digestive system can take up them extra effectively than entire collagen protein. Analysis exhibits that collagen peptides can enter the bloodstream inside hours of consumption (Virgilio et al., 2024).

2. Flexibility in Use. Collagen peptides dissolve simply in each cold and hot liquids, making them handy to combine into espresso, smoothies, or soups with out altering the style or texture. In addition they have benefits for men and ladies.

3. Analysis on Pores and skin Advantages. Some research counsel that collagen peptides might stimulate pores and skin cells (known as fibroblasts) to supply extra collagen and elastin. This may translate into improved pores and skin hydration, elasticity, and diminished wrinkles (Pu et al., 2023; Inamadar & Palit, 2023).

4. Help Past Pores and skin. Collagen peptides may support in joint consolation, bone power, and train restoration, making them interesting not just for magnificence but in addition for total well being (Larder et al., 2023).

Are Collagen Peptides Higher for Pores and skin?

This is the place most individuals are curious. Whereas collagen in its natural state is just too massive for the physique to soak up effectively, collagen peptides are sufficiently small to make it by way of the intestine and flow into within the bloodstream.

Research have discovered that common consumption of collagen peptides (normally 2.5–10 grams per day, some counsel as much as 15g) can:

• Improve pores and skin elasticity for a firmer look.
• Increase pores and skin hydration, lowering dryness.
• Scale back the looks of wrinkles over time (Pu et al., 2023; Reilly et al., 2024; Inamadar & Palit, 2023).

These outcomes aren’t instantaneous, however many trials have proven noticeable enhancements after 8–12 weeks of constant use.

Collagen peptides will not cease getting old altogether, however they seem to help the pores and skin’s pure construction higher than entire collagen dietary supplements.

Can Your Pores and skin Take in Collagen Peptides?

This is a supply of confusion as folks will use collagen in moisturizers. Nevertheless, collagen peptides are too massive and hydrophilic to penetrate the stratum corneum (the pores and skin’s barrier) and attain the deeper layers.

So why use it as pores and skin cream? Moisturizer. Collagen peptide lotions are used topically as a result of they act as; 

• A humectant which helps entice and maintain water.
• Movie-forming agent (creating a skinny layer that reduces transepidermal water loss).

With that mentioned, the proof helps using oral collagen peptides to stimulate collagen manufacturing.  Or you should use sure lively topical substances (like retinoids, vitamin C, or engineered signaling peptides), not plain collagen cream.

Which One Ought to You Purchase?

Here is the easy fact:

• Collagen protein in its pure type is not helpful as a complement as a result of it is tougher to digest and take up.
• Collagen peptides are the extra sensible possibility, as they’re simpler for the physique to make the most of, and most analysis on pores and skin, joints, and total advantages is predicated on peptides (Harvard Well being Publishing, 2023).

With this in thoughts, observe that the phrase “hydrolyzed collagen” is identical factor as “collagen peptides”. When purchasing supplements, many merchandise will use collagen peptides, so if it does not say “peptides”, it can most likely say “hydrolyzed collagen”.

Backside Line

Collagen is the physique’s most essential structural protein, conserving your pores and skin, joints, and bones sturdy. However relating to dietary supplements, the actual distinction lies within the type:

• Collagen (entire protein): massive, troublesome to digest, and fewer efficient when consumed.
• Collagen peptides (hydrolyzed collagen): smaller fragments, simple to soak up, supported by analysis for pores and skin and joint advantages.

For those who’re looking for a collagen complement, collagen peptides are the best way to go. They’re simpler to make use of, higher absorbed, and extra prone to provide the outcomes you are hoping for.

Steadily Requested Questions (FAQ)

1. Are collagen and collagen peptides the identical factor?

Not precisely. Collagen is a full protein, whereas collagen peptides are smaller, broken-down fragments of collagen which can be simpler for the physique to soak up.

2. Do collagen peptides actually work for pores and skin?

Analysis means that collagen peptides can improve pores and skin elasticity and hydration, in addition to scale back wrinkles, when taken persistently for 8–12 weeks (Pu et al., 2023; Reilly et al., 2024).

3. Can I get collagen naturally from meals?

Sure. Meals like bone broth, hen pores and skin, fish pores and skin, and beef comprise collagen. Nevertheless, dietary supplements present a extra concentrated and handy supply.

4. Which is best to purchase: collagen or collagen peptides?

Collagen peptides are the higher alternative. They’re extra bioavailable, simpler to combine into drinks, and supported by research for pores and skin and joint well being (Harvard Well being Publishing, 2023)

5. Ought to I buy collagen peptide powder or tablets?

The principle advantage of tablets is comfort. Nevertheless, it prices extra, it limits the flexibility to dose, you are unable to place it in smoothies, and it is the same collagen found in powder. Due to this fact, until you have a necessity for the comfort, there isn’t any profit from tablets.
