Vitamin D
Vitamin D is both a nutrient we eat and a type of vitamin our bodies make. It is a fat-soluble vitamin. In general, Vitamin D helps the body absorb and retain calcium and phosphorus; both are required for maintaining bone density and formation of new bone.
Some food naturally contain vitamin D, for example:-
oily fish – such as salmon, sardines, herring and mackerel
red meat
liver
egg yolks
fortified foods – such as some fat spreads and breakfast cereals
mushrooms
For most people, the best way to get enough vitamin D is taking supplement, especially people with vegetarian diet. Vitamin D supplements are available in two forms: vitamin D2 (“ergocalciferol” or pre-vitamin D) and vitamin D3 (“cholecalciferol”). Both are also naturally occurring forms that are produced in the presence of the sun’s ultraviolet-B (UVB) rays, hence its nickname, “the sunshine vitamin.
A recent research in the International Journal of Endocrinology published in 2018
[1] has concluded that vitamin D can
affect testosterone levels and
correcting vitamin D deficiency will effectively improve male sexual health.It has been established that vitamin D deficiency is linked to poor male sexual function (especially
erectile dysfunction). In the mentioned research, the participants had measurements of
serum testosterone,
Vitamin D, and completed the
International Index of Erectile Function-15 (IIEF-15) questionnaire, a series of questions that gauges erectile and orgasmic function, sexual desire, intercourse satisfaction, and overall satisfaction. Higher scores on the IIEF-15 indicate better sexual function.
The researchers found that higher levels of vitamin D were associated with higher levels of total testosterone and higher scores on all domains of the IIEF-15. In addition, higher levels of total testosterone were associated with better erectile function and higher total IIEF scores.
In the research discussion, the authors discussed possible reasons behind the vitamin D/sexual function relationship. It is postulated that vitamin D protect the inner linings of the blood vessels from oxidative stress (improves vascular integrity), thus improving thus improving erections. Also, vitamin D deficiency is associated with cardiovascular risk that can also affect sexual function; healthy levels of vitamin D may mitigate this risk and, in turn, benefit sexual health.
It is also noted that
diabetic men and
smokers tended to have
lower testosterone levels. This means that those with such risk factors and sexual dysfunction should screen for Vit D deficiency.
They research has concluded that vitamin D plays an essential role in men’s sexual function and that supplementation can improve it. “If our data will be further confirmed, vitamin D evaluation might be included in the near future in the clinical work-up protocol of male sexual dysfunction,” they wrote.
Zinc
Zinc is considered an essential nutrient, meaning that your body can’t produce or store it.
For this reason, you must get a constant supply through your diet or supplement.
Zinc is required for numerous processes in your body, including
Gene expression
Enzymatic reactions
Immune function
Protein synthesis
DNA synthesis
Wound healing
Growth and development
Zinc is naturally found in a wide variety of both plant and animal foods.
Foods highest in zinc include
Shellfish: Oysters, crab, mussels, lobster and clams
Meat: Beef, pork, lamb and bison
Poultry: Turkey and chicken
Fish: Flounder, sardines, salmon and sole
Dairy products: Milk, yogurt and cheese
Eggs
Whole grains: Oats, quinoa, brown rice, etc.
Certain vegetables: Mushrooms, kale, peas, asparagus and beet greens
You can also take zinc supplements or multi-nutrient supplements that provide zinc.
A Journal published in 1996 [2] explained how zinc affects serum testosterone levels. A group of young men with zinc deficient diet were studied and displayed both zinc and testosterone deficiency. Testosterone levels were measured and there was a significant decrease (almost 75 percent) after 20 weeks of a low-zinc diet.
The study also examined zinc supplementation in elderly men. In this study, testosterone levels in the elderly population had almost doubled when given the appropriate amount of zinc supplementation. Hence, it can be concluded that zinc is paramount for testosterone production.
For an adult male,
11 milligrams of zinc per day is considered the ideal amount to consume. Women should limit their zinc intake to 8 milligrams per day.
A high-protein diet will usually contain enough zinc. Meats such as beef, pork, lamb, and chicken are all good sources of zinc. Nuts, whole grains, legumes, and yeast also contain zinc.
PROfertil
Spermatogenesis is the medical term for the production of sperm in the human male body. Spermatogenesis takes about three months. For this to happen, the human body needs various essential nutritive substances to support the various development stages of the sperm cell, such as vitamins, vitamin-like substances, trace elements, mineral substances and amino acids. These nutrients are needed for optimal production of normal and healthy sperms.
PROfertil is a medical dietary supplement containing a number of micronutrients which work to improve male fertility levels. It contains the vitamins, minerals and enzymes necessary for healthy sperm production.
The contents of profertil are such as:-
- L-carnitine
- L-arginine
- Coenzyme Q10
- Vitamin E
- Zinc
- Folic acid
- Glutathione
- Selenium
The breakdown of the proven effects of each micronutrients within PROfertil are as highlighted:-
