Special Women’s Multivitamins

Today, we are going to talk about Special Women’s Multivitamins. What are their features and why there has to be specific supplements for women?

Why take a specific multivitamin

The current market offers many vitamins and mineral complexes with different formulas designed for different people.

Multivitamins

Multivitamins for Women and Men by EssentialSeries.

These products are designed to meet the general requirements of the population, according to the statements of the international health organizations which established the recommended daily doses.

Nutrient reference value

Figure I. Nutrient reference values for adults.

In general, a multivitamin-multimineral is a product formulated with high amounts of non-energy nutrients that contribute to the maintenance of the normal functioning of the body.

European recommendations

In Europe, we can find the nutrient reference values (NRVs) in the regulation 1169/2011 from the EU. Above all, it establishes the amount of vitamins, minerals and some trace elements that are necessary for our body.

Recommendations for women

However, we know that, even if the NRVs meet the requirements of most of the population, they may not be enough in some cases.

For example, women of childbearing age need to take more iron than what is established in those reference values.

Even if they compensate the blood loss from menstruation with a higher iron absorption in the bowel (Ganz, Nemeth, 2012), women lose twice as much iron than men. Consequently, there are three times more cases of iron deficiency in this sex (Clénin, 2017).

Anemia is frequent in women

A chronic iron deficiency can trigger hypochromia and erythrocytic microcytosis and ultimately iron deficiency anemia.

This pathology is quite frequent in menstruating and pregnant women. This problem can be easily fixed by increasing the iron intake (McDonagh et al., 2015).

A man who does not suffer an iron deficiency should not take high iron doses. This is due to the fact the risk of its accumulation in the liver and hemochromatosis is much higher than in women.

Iron saturation

This should serve as an example of how: Certain amounts of nutrients need to be individually adjusted depending on the circumstances of a specific group of people: in this case, women.

Women’s Multivitamins: Ultimate Women’s Multi

In HSN, we are aware that we have to adapt the multivitamin formulas to the needs of women. That is why we have come up with a more specific product for this groups than our classic Evovits.

Women care

Figure IV. Women’s Care by EssentialSeries.

Women’s Care was born after doing a rigorous screening of the scientific literature that reviews the role of different nutrients on women’s health.

Product development

It has been specially designed to meet the essential micronutrient requirements of an athlete or a women who wants to be healthy and improve their nutrition.

These are some of the ingredients from its formula:

  • Complete water-soluble vitamin spectrum (B-complex vitamins and vitamin C)
  • 4 fat-soluble vitamins (A, D, E and K)
  • Minerals like Zinc
  • Trace elements (like copper or selenium)
  • Plant extract (like aloe vera extract or cranberry extract)
  • Other nutrients like Lutein and Coenzyme Q10

From all of them:

  • A part provides a basic nutrient supply that anyone needs if we take into account the recommended daily doses to avoid nutrient deficiencies.
  • The other part has been specially formulated for women. For example, we can highlight the role of folic acid.

Lunges

Folate is vitamin B9 which is sold as a supplement like folic acid. It is stable and the body breaks it down to its active folate form.

Folic Acid

Folate is an important cofactor in different metabolic processes.

For example, this vitamin is reduced twice until it becomes tetrahydrofolate. This is a catalyst for the de novo synthesis of purines and nucleic acids, which is essential for erythropoiesis.

When there is a folate deficiency, the body synthesizes less DNA. Consequently, this affects the cell division process and the erythrocytes (red cells) are synthesized with a big medium corpuscular volume. This can result in an increase of the production of megaloblasts, also known as megaloblastic anemia.

Folate deficiency in women

There are many women who suffer a folate deficiency from puberty onward. This deficiency can be very dangerous for the growth of the fetus.

Women use a lot of folate during the embryonic development, increasing the requirements of this vitamin exponentially.

A folate deficiency during pregnancy can cause neutral tube malformations in the fetus. Some of them are incompatible with life (like anencephaly). But we can easily prevent this problem by increasing the intake of this vitamin.

That is why doctors advise folic acid supplementation for women even a month before becoming pregnant and up to 3 months after giving birth.

Folic acid supplementation during pregnancy is effective, lowering the onset of neural tube defects in almost a 75% (RR 0.28).

RR tree diagram

Copper

Copper is a trace element that performs important functions in the metabolism such as making up different enzymes. These are responsible for many of the reactions of our metabolic system.

For example:

  • Amine oxidation.
  • Neurotransmitter synthesis.
  • Formation of cross-linked collagen.

Roller

A copper deficiency can lead to the onset of erythrocytic hypochromia and anemia.

One of its most interesting functions is the integration of ceruloplasmin, a protein that is in charge of oxidizing ferrous iron (FE2+) to ferric iron (FE3+). Consequently, it becomes bioavailable and it can be transported by transferrin (protein that transports iron in the blood) which is only compatible with FE3+.

Inositol

Inositol is a polyol that has proven to be effective when it comes to buffering the clinical symptoms of polycystic ovary syndrome.

It is a very common pseudopathological disorder in women after puberty due to a deregulation of the androgen production. It is due to a high peripheral resistance to insulin and an increase of its production.

Polycystic ovary syndrome

Figure VI. Basic representation of the endocrine physiopathology of polycystic ovary syndrome.

Here you have a very interesting article about inositol’s potential to treat POS (Polycystic Ovary Syndrome).

Inositol and polycystic ovary syndrome

The polycystic ovary syndrome produces endocrine-metabolic alterations such as:

  • Hirsutism: increase in the production of body hair.
  • Oligomenorrhea: menstrual alterations until the period completely disappears, amenorrhea.
It is mostly controlled through the diet, physical exercise and body weight control.

But inositol also directly supports the hormone balance by supporting the absorption of glucose without having to produce more insulin. Consequently, it reduces the exposure to IRS-1 and buffers all the effects from the previous image.

Myo-inositol and insulin

Iron

It is the metal used by the body to produce different proteins such as hemoglobin and myoglobin, ribonucleotide-reductase, CYP450 or mitochondrial respiratory chain complexes.

Iron is necessary to obtain energy from the oxidation of nutrients.

However, its most popular function, and possibly the most relevant, is the formation of globular proteins from erythrocytes and the skeletal and heart muscle (hemoglobin and myoglobin, respectively).

Iron and anemia

Iron is essential when it comes to maintaining healthy globin concentrations:

  • Allowing the oxygen transport and retention in the tissues.
  • Maintaining an adequate red cell density (chromy).

Oxygen saturation

Preventing symptoms which are very common in female athletes such as:  fatigue, apathy, anorexia and inability to tolerate efforts due to a low affinity between hemoglobin and oxygen.
