Special Men’s Multivitamin

In this article, we are going to talk about Special Men’s Multivitamins: What are their features? Why are there a specific supplements for men?

Why take a specific multivitamin?

Most of the multivitamins available in the market have been designed with a series of generic vitamins and minerals. These are useful both for men and women.

Multivitamins

Multivitamins for Women and Men by EssentialSeries.

Regardless of their nutrient requirements, since the nutrient reference value established by the European Committee does not make a distinction between the sexes.

Nutrient Reference Values

Then, do men and women have to take the same vitamins and minerals? Yes, but perhaps not the same amounts.

Advice for men

Some world health organization like the American IoM establish some differences between the sexes, because men usually need more nutrients than women:

Daily recommended intake of vitamins

Figure II. DRIS of vitamins according to age and sex. We have used red to highlight some of the differences between men and women of the same age.

Basal metabolism in both sexes

This is due to the fact that men have more fat-free mass than women, which is directly related to the basal metabolism.

Fat-free mass and metabolic rate

Figure III. Positive correlation between fat-free mass (axis X) and metabolic rate while resting (axis Y). The more fat-free mass, the higher the metabolic rate.

But even after standardizing the fat-free mass, men have a higher metabolic rate than women. Some mechanisms that regulate the REDOX processes are over-expressed in men.

Metabolic rate between men and women

Figure IV. Differences in the energy expenditure while resting between men and women (A). After adjusting the “fat-free mass” variable to prevent it from affecting the results (B). Men have a higher RMR than women regardless of their fat-free mass.

We have to adapt the needs

The metabolic rate is the result of many processes that use energy, producing heat.

There are several vitamins, minerals and trace elements involved in this processes. These elements are called “cofactors”.

Well, since men have an “accelerated metabolism” when compared to women. Consequently, they need more cofactors, that is, more vitamins and minerals.

Evidently, some multivitamins may lack some nutrients in order to be as generic as possible for the highest number of people without risks.

Cyclist

But pay attention, because HSN has come up with a new product.

Multivitamins for Men: Men’s Care

Ultimate Men’s Multi has been specially designed to meet the micronutrient requirements of the most demanding men.

Nutrient intake distribution

It is the most complete multimineral-multivitamin for those who want an extra nutrient supply to meet their daily requirements.

HSN Men's Care

Figure VI. Men’s Care by EssentialSeries.

  • This product contains a high percentage of vitamins, minerals and trace elements.
  • Apart from highly concentrated plant extracts that have been specially selected to deal with the specific requirements of men.

Above all, it has been designed to do what any multivitamin should do:

Providing nutritional support to those who have high energy requirements or diets that lack micronutrients.

What are the ingredients from Ultimate Men’s Multi?

Ultimate Men’s Multi has been formulated with a complete vitamin spectrum.

All of them are present in enough doses to meet the recommended dietary intake (except for vitamin K, which provides a 53% of the NRV due to the fact that is available in everyday products).

Apart from vitamins, Ultimate Men’s Multi contains minerals such as zinc and trace elements like iodine or selenium. They have been specially selected due to their action mechanism on the metabolism of men.

Abs wheel
Zinc is an essential mineral that plays a number of roles in the metabolic maintenance of the body.

Zinc content

One of the effects of zinc that men are most interested in is its acclaimed ability to increase testosterone levels, as this hormone is directly linked to healthy sexual performance and increases in muscle mass.

The relation between zinc and the balance of the androgenic system is complex. There are several processes involved such as the conversion of cholesterol to sex hormones and the role of zinc in cell receptors.

A zinc deficiency has been related to a drop of the testosterone synthesis and metabolic response to free testosterone (due to a lower affinity to the androgenic receptor).

Studies from the last century, when the control of the ethical committees was not as important, they tested how the testosterone concentrations of men dropped when they were subjected to a dietary restriction of zinc. Consequently, they altered the concentrations of this mineral in the body.

Zinc and testosterone

Figure VII. Relation between zinc leukocyte concentration and testosterone after 8 and 20 weeks of severe zinc dietary restriction.

The efficacy of zinc on preserving the testosterone concentrations has been supported by important organizations like the IoM and EFSA. That is why its use is completely fair, specially if we take into account that moderate doses (240mg of zinc sulfate a day) can increase the testosterone concentrations in eugonadal men (without testicular disorders).

Effects of zinc on the spermatozoa

Iodine and Selenium importance

Part of our daily energy expenditure is regulated by our thyroid metabolism.

Therefore, alterations in the synthesis of thyroid hormones (clinical or subclinical hypothyroidism) can affect our health and reduce the basal metabolic rate.

Iodine is an essential element in the thyroid metabolism, since it is a precursor of the synthesis of active hormones.

Synthesis of Thyroid Hormones

Figure IX. Simplified mechanism of the endogenous synthesis of thyroid hormones.

It is in charge of providing an iodine molecule to form MIT, DIT. Then, these will bind together to form the active hormone (T3).

Selenium is a basic structural element of some selenoproteins such as deiodinase iodothyronine. This substance will transform the prohormone (T4) into the active hormone (T3).

A deficiency of these elements can affect the synthesis of thyroid hormones and trigger hormone alterations in men.

That is why it is important to ensure their intake through some of its main dietary sources such as iodized salt. In fact, many people actually do not use it.

Runner

If you are an athlete, supplement your diet with the best multivitamin.

This product acts as a cardio-metabolic health shielding agent and may improve circulation and possibly reduce blood pressure. However, more human studies are needed to conclude this.
