Fill up on vitamin E: how and why?
Vitamins are the most important molecules that your body is unable to synthesize and can only be obtained through food.
Your needs in vitamin E, for example, can only be covered by the consumption of certain ingredients such as oils (soya, sunflower, wheat), nuts, seeds or even cereals.
However, it is not always easy to compose a sufficiently varied food bowl.
In such a situation, the alternative to consuming conventional foodstuffs is to take a targeted food supplement.
While there are many sites on the web that give you tips on how you should adjust your diet to avoid deficiencies and provide your body with everything it needs to be healthy, few explain why vitamin E is necessary for your cells and how it is processed by your body.
The MyPUREskin team is accustomed to exploring the topics it covers in depth to help you understand what you should be eating, why and how, and takes you on a journey to the heart of your nutrition mechanisms.

Vitamins, membrane transport and cells: how does vitamin E get into your body?
Regrouping eight different molecules with common functions, vitamin E takes off from your plate to travel to the cells of your body in 4 steps:
- You consume foods or supplements containing vitamin E;
- Your digestive system extracts nutrients from what you eat, including vitamin E;
- The vitamin E passes through the wall of your intestine;
- It reaches your bloodstream and enters the various cells of your body.
Whether it’s your intestine, your heart or your skin, the cells of your body are like “VIP spaces” where the active ingredients you consume meet.
These tiny constituents of your body have entrance doors that guests (like vitamins) can use as long as they have a pass.
To leave your digestive system, vitamin E must therefore undergo an initial “identity check”, orchestrated by specialized cells lining your intestinal wall: the enterocytes.
The pathways of vitamin E in enterocytes
In order to have a chance to pass from the “intestinal lumen” (i.e. the inside of your intestine) to the enterocytes, vitamin E is enclosed in “small oil bubbles” (lipid emulsions) that will break down into smaller water-soluble lipid units: the water-soluble micelles.
It was thought for a long time that the penetration of vitamin E into the enterocytes via the micelles was done passively, thanks to the particular shape of these cells (due to their microvilli, resembling tentacles that bathe in the intestinal lumen).
It is only since the work of Emmanuelle Reboul published in 2006¹ that we know the existence of a specific protein allowing fat-soluble vitamins (i.e. vitamins capable of “clinging” to lipids), such as vitamin E, to cross the membrane of enterocyte cells.
Vitamin E uses this membrane transporter from which it will separate once in the cell.
Vitamin E and chylomicrons: from enterocytes to the bloodstream
However, vitamin E is not yet ready to enter the bloodstream.
In order to pass the part of the cell membrane next to the blood vessels (the “basal” membrane), it has to prepare itself.
This is why enterocytes produce lipoproteins, which are able to pass hydrophobic molecules (such as vitamin E, which is fat-soluble) into the blood (which “prefers” hydrophilic molecules).
More precisely, it is the chylomicrons, lipoproteins produced during digestion, which are responsible for transporting vitamin E past the second membrane control and into the bloodstream.
From the liver to other organs: the last stop for vitamin E
Once in the blood, vitamin E once again abandons its carriers (chylomicrons) and heads for the liver, which will produce other lipoproteins. These will take over for the last stage of the journey.
They will carry the vitamin E to all the cells of your other organs, to release them.
Vitamin E and synergy: from blood vessels to your organ cells
It is only once it has reached the various cells where it is expected that vitamin E can begin to work.
By reaching the heart, then the lungs, but also eventually the skin, vitamin E will be processed by your cells to contribute to the good realization of certain reactions but will also and especially be dispatched to their surface.
Acting then as a free radical neutralizer, vitamin E will protect the cell wall from oxidative stress and will thus contribute to improve the quality of the reactions occurring in your cells, while increasing their potential life expectancy.
Vitamin E synergy: why consume other active ingredients with vitamin E?
As Jean-Claude Guilland of the biology technical platform of the Dijon University Hospital reminds us in an article published in March 2011², the life cycle of vitamin E is closely linked to the presence of vitamin C.
Indeed, the presence of these two active ingredients increases the life span of vitamin E. This capacity to obtain different effects when two active principles are consumed simultaneously, compared to their separate ingestion, is called “synergy”.
Faced with the loss of nutritional value of fruits and vegetables produced over the last hundred years on an industrial scale (whose varieties are not necessarily selected for their level of nutrition), the consumption of food supplements is of interest to more and more people.
In addition, the progressive disruption of various cellular functions induced by the aging process raises a question: how to choose an effective food supplement that respects your health?
MyCollagenLift: a nutricosmetic that respects your nutritional needs
It is because nutrition represents an essential pillar of your daily quality of life that MyPUREskin laboratories have chosen to deploy their know-how and energy to help you optimize it.
By creating a formula with proven effectiveness, our team has taken advantage of the properties of vitamin E and the synergy that links it to a batch of ingredients of entirely natural origin.
“Nourish, stimulate, protect”: the maxim of the food supplement that is MyCollagenLift is of absolute relevance, in an effort to accompany your aging process, thanks to :
- Vitamin E whose support in terms of neutralizing free radicals is a breath of oxygen for your skin;
- Vitamin C (extracted from the acerola fruit) whose antioxidant power makes it an essential molecule for a quality formula;
- Collagen peptides (more bioavailable than non-hydrolyzed collagen) that help your body continue its production of endogenous collagen;
- Hyaluronic acid, the cornerstone of intense hydration for your skin;
- Wheat ceramides (gluten-free), whose properties accompany this hydration process by helping to prevent your body’s insensible loss of water;
- Organic silicon, whose role as a skin restorer is a wonderful accompaniment to your body’s efforts to maintain the firmness of your skin;
- Grape OPC and zinc whose relevance to free electrons increases the effectiveness of the MyCollagenLift formula.
Studied to offer your body all the effectiveness of a combination of active ingredients in phase with the latest scientific discoveries in nutrition, MyCollagenLift will accompany you at every stage of your life to support you in your quest for “wellness”.
Still hesitating to take the plunge? Remember this: for an initial 3-month treatment, the first results will be visible after 4 weeks!
