Hyaluronic acid and marine collagen: why is the molecular weight important?
If hyaluronic acid and marine collagen are both key ingredients for anti-aging nutricosmetics, they do not necessarily have the same effectiveness from one formula to another. There are several reasons for this. One of them is their molecular weight, which has an impact on their bioavailability. Bioavailability ? Molecular weight? What are they? Why do they vary? How does it affect the effectiveness of nutricosmetics? Learn to understand what makes an anti-aging dietary supplement a meaningful choice and how to choose a first-in-class nutricosmetic in the future.
Molecular weight: a number that counts for your digestive system
Food is your body’s primary way of getting all the nutrients it needs. When you eat food, your digestive system removes a host of small molecules that are necessary for the functioning of each of your organs, including the largest of them: your skin. This system is very well organized, and it moves food through a circuit with superb mechanics. Each step of this circuit takes place in a different organ and each of these organs has a very precise function, adapted to receive a certain molecular weight.
But, what is molecular weight?
Despite what its name may suggest, the molecular weight is an indicator that gives an idea of the size of a molecule. It is a measure that can be applied to any molecule in chemistry. It is a number without unit because it corresponds to a quotient. This quotient is the result of the division of the mass of the molecule in relation to a reference unit in chemistry: the amu (atomic mass unit). Beyond these technical details, what is important to understand is that the higher the molecular weight of a molecule, the “bigger” it is.
The journey of marine collagen and hyaluronic acid in your body
Thus, when you consume food containing marine collagen from fish, your digestive system sends it into this famous digestion circuit. The same is true when you consume ingredients rich in hyaluronic acid such as cod liver oil. This journey begins in your mouth where your saliva and the chewing effort of your jaw will grind your food into smaller pieces. The smaller pieces of food then travel down your esophagus to your stomach.
How does the molecular weight change in the stomach?
Collagen and hyaluronic acid are two very different molecules and do not react in the same way to the action of the stomach.
Collagen in the stomach
The collagen molecules contained in your food are broken down into smaller units. Together with other nutrients extracted from the ingredients you have consumed, these smaller collagen molecules form a paste-like liquid that can be received and processed by the next organ. The stomach achieves this feat by means of stirring movements (produced by the stomach muscles) and gastric juices. The molecular weight of the collagen will have decreased and it will be able to continue its circuit in your digestive system.
Hyaluronic acid in the stomach
The hyaluronic acid is not sensitive to the gastric juices of the stomach and is sent with almost no reduction in its molecular weight to the next organ.
How does the molecular weight evolve in the intestine?
Collagen in the intestine
However, collagen is still too “big” when it leaves the stomach to enter the bloodstream. Therefore, it cannot be used properly. This is why the small intestine intervenes by soliciting its own gastric juices which break down the collagen molecules into even smaller units: collagen peptides.
Hyaluronic acid in the intestine
Moreover, it is also in the intestine that hyaluronic acid is transformed to be used by your skin. Indeed, by breaking it down into smaller molecules, gastric juices make it capable of passing into the bloodstream.
Digestion and nutritional losses: why nutricosmetics?
However, some of the collagen and hyaluronic acid that you consume is necessarily lost. This loss is explained by the impossibility of your digestive system to perfectly process the food that it consumes, generating a waste that leaves in the stools.
It is precisely because the digestive system is not able to perfectly assimilate collagen and hyaluronic acid that nutricosmetics takes over. It does this by reducing, even before being consumed, the molecular weight of marine collagen and by choosing a hyaluronic acid with an already low molecular weight. The synergy of hyaluronic acid and marine collagen can be expressed even better, since these active ingredients are less “wasted” by the digestive system, since they are already small enough to pass into the bloodstream. It is notably thanks to studies such as that of Dr. Do-Un¹ and Dr. Watanabe² that we have understood what anti-aging nutricosmetics could bring to the human body. Indeed, we now know that the supplementation of collagen bio-peptides (with a lower molecular weight than the collagen macro-molecule) offers much better rejuvenating effects to the skin, in particular:
- Better elasticity and firmness;
- Greater firmness for smoother, plumper skin.
Hyaluronic acid supplementation offers the dermis and the epidermis :
- A better hydration, in depth;
- A reduction in wrinkles and fine lines.
MyCollagenLift: an efficiency without compromise
This is why the anti-aging experts of the MyPUREskin team have chosen bio peptides of marine collagen and highly synergistic hyaluronic acid of low molecular weight, therefore very “bioavailable” (easily assimilated by your body). In doing so, they have developed a food supplement with exceptional moisturizing and anti-aging effects.
But what makes MyCollagenLift a “first-in-class” nutricosmetic is the batch of all-natural and carefully selected ingredients that are used to offer unique cellular protection. Thus, its formula contains :
- Marine collagen bio peptides capable of replacing your lost collagen and stimulating its production;
- Hyaluronic acid moisturizes your skin in depth;
- Ceramides protect the collagen bio peptides as they travel through your body and support your skin's hydration efforts;
- Organic silicon to restructure the skin, but also to prolong collagen protection and preserve elastin;
- Vitamins C and E (powerful antioxidants);
- Grape polyphenols (complementary antioxidants);
- SOD (Super Oxide Dismutase) enzyme offering a double cellular protection (inside and outside the cell);
- Zinc supporting the effects of antioxidants and especially promoting the action of SOD.
The synergistic cocktail of ingredients in MyCollagenLift is therefore a guarantee of effectiveness against premature aging.
This is what allowed it to be declared “a product of exceptional quality to fight against oxidative stress” after its evaluation by the IEA. Ready to discover these effects for yourself?
