Conquering Nutrient Deficiencies in Mature Men

People with busy lives often are under considerable stress, which can deplete the body of key nutrients. Plus if you often eat processed food on the go, your body will be lack of the nutritional value offered by fresh and freshly cooked foods.

As men reach their forties and beyond, the body may require higher levels of key nutrients that cannot be provided easily by diets, partially due to slower metabolism, poorer absorption of nutrients into the bloodstream, and reductions in organ function. Taking certain medications can also interfere with absorption of important nutrients from food.

As a result, these deficiencies can lead to other diseases ranging from minor to severe, including fatigue, loss of bone and muscle mass, diminished sexual function, and other conditions.

Roles of key nutrients in men’s health and symptoms of deficiency

To boost strength, bone and muscle mass, sexual vigour, mental sharpness, and health of many organs in the body, dietary supplements of vitamins, minerals, and other key nutrients coupled with a healthy diet are keys to wellness for men in mid-life and later in life. 

Important nutrients for men’s health are the following:

  • Vitamin B12 is involved in synthesis and regulation of DNA; metabolism of amino acids (building blocks of proteins) and fatty acids,’ proper function of the brain, nervous system, eyes, and liver; stabilising receptor sites on cell membranes for proper binding of hormones; stimulating production of red blood cells; and as a cofactor for certain enzymes. Insufficient levels or inadequate absorption of vitamin B12 can result in anaemia (low levels of red blood cells) that can cause fatigue; gastrointestinal disturbances; depression; poor memory; manic moods; and psychosis (inability to recognise what is real). 
  • Vitamin D3 (cholecalciferol) is synthesised in the skin in response to sunlight. Cholecalciferol is important for healthy bones and teeth in mature men, as well as for healthy levels of calcium and phosphorus. Symptoms of inadequate levels of vitamin D3 include discomfort, thinning, and fracture of the bones; muscle weakness; and impaired ability to think.

  • Vitamin K2 (a menaquinone) is needed for proper blood clotting; movement of calcium to the bones and bloodstream; protection of the nervous system from calcium deposits, and as a cofactor for certain enzymes. Signs and symptoms of  vitamin K2 deficiency include bruising and bleeding, calcium deposits in the nervous system resulting in decreased cognitive function, calcium deposits in the arteries, and formation of bone spurs.
  • Calcium is important for healthy bones and teeth, muscle contractions, signalling between nerve cells, neutralisation of excess stomach acid, managing the level of phosphates in the blood, and regulation of heart rhythms. Inadequate levels of calcium can cause discomfort, thinning (loss of bone mass), and fracture of the bones and teeth; muscle tremours and involuntary muscle contractions; and abnormal rhythms of the heart.
  • Magnesium is important as a part of many enzymes, plays a role in metabolism and production of energy in cells, and is involved in health of the heart, bones, pancreas, and immune system. Inadequate levels of magnesium include muscle cramps, insomnia, anxiety, headaches, abnormal blood pressure, and low bone density.
  • Ubiquinol Coenzyme Q10 is important for health of the heart and cardiovascular system, brain and nervous system, liver, kidneys, and immune system; regulation of blood pressure and cholesterol synthesis; ATP synthesis and energy production; and healthy sperm. As an antioxidant, ubiquinol CoQ10 protects the body from damage due to reactive molecules, called free radicals. Insufficient levels of ubiquinol CoQ10 cause high blood pressure, chest pain, and heart failure.
  • Omega 3 fatty acids, which are found in fish oil and nut oils suppress inflammation in cells, are involved in health of the heart, and joints, and are important for cognitive and behavioural function.

Symptoms of omega-3 fatty acid deficiency include poor memory, mood swings and depression, fatigue, dry skin, impaired circulation, and heart disease.

The best way for mature men to get adequate nutrients

A healthy diet including fresh and freshly cooked organic whole grains, nuts, fruits, vegetables, cheese, eggs, meats, poultry, fish, and bottled mineral water contains some vitamins, minerals, and other key nutrients needed by mature men.

However, for men in mid-life and beyond, it may be difficult to get sufficient levels of nutrients from just their diets, even if the choice of foods are healthy. Therefore, taking daily nutritional supplements is a great way for mature men to boost their levels of key nutrients.

How to select dietary supplements for men?

Choose dietary supplements from a reputable nutritional supplement manufacturer, make sure that the supplements you select are absorbed easily by the body, and pick the appropriate dose for the nutrients desired.

Xtendlife supplements have the following advantages:

  • We use GMP approved, independent lab testing to ensure purity
  • Lack iron to avoid lowering effectiveness of other supplements
  • Our calcium supplements do not come from dairy products but instead come from marine plants (fossilised seaweed). These calcium nutrients are well absorbed by the body.
  • Our coenzyme Q10 supplement is ubiquinol, which is easily absorbed and used by the body.

Xtendlife offers a broad range of nutritional supplements for men, including products that address specific nutrient deficiencies.

Seize the opportunity, and restore your body, function, and health to a more youthful you!
