As a result of better hygiene, and on the other hand significant advances in medicine, human life expectancy is longer than just a few decades ago. Unfortunately, despite many achievements, we have not actually become much healthier, and the reasons for that are poor diet, alcohol, cigarettes, lack of physical activity, stress and dehydration. Proper and balanced diet is an important part of healthy aging, because it ensures the intake of necessary nutrients and reduces the risk of developing chronic diseases. Special emphasis is placed on B vitamins, vitamin D, and the minerals are iron, calcium, zinc and magnesium. In addition, protein intake is important. That is why Strath, a natural dietary supplement, is ideal for the elderly because it contains more than 61 metabolically active substances, including vitamins, minerals, all amino acids and other important building blocks. Regardless of the fact that older people have reduced energy needs, they need the same or even greater amount of nutrients, compared to the needs of the younger population. In order to maintain or improve the quality of their lives, much more attention should be paid to proper eating habits, and the quality and selection of foods suitable for this age group. Strath syrup and tablets enable not only adequate intake of vitamins, minerals and amino acids, but also better absorption and utilization of building materials that are ingested. This plasmolized plant yeast shows numerous beneficial effects on maintaining the health of the whole organism and is recommended for the elderly who have decreased appetite, have weakened cognitive abilities and have reduced bone mass. Such claims are supported by numerous clinical studies behind Strath, with special reference to those done with oncology patients, which show a significant improvement in the quality of life.
