Zinc 30 capsules YAMAMOTO

Yamamoto® Research Zinc is a zinc supplement in the picolinate form , characterized by excellent bioavailability for our body, unlike more common forms of zinc. Zinc is a essential micronutrient for the body: it is involved in the DNA synthesis , in immune function , in protein synthesis , in cell division , in wound healing and has action antioxidant and defense against viruses, bacteria and fungi. This precious mineral is also involved in the production of thyroid hormones (zinc deficiency prevents the conversion of T4 to T3), insulin and thymulin, and is involved in the synthesis of male sex hormones such as testosterone . It also helps maintain the healthy skin, hair and nails and has great importance for the development and the growth , especially in children.

Zinc is an often overlooked essential trace element, despite its presence in the human body at approximately 2 grams and its involvement in over 300 enzymes involved in DNA/RNA synthesis, the regulation of growth and development, and immune, digestive, and metabolic functions. The enzyme carbonate dehydratase, in particular, allows the body to eliminate carbon dioxide produced in tissues. Zinc is also important for the formation of collagenases and for regulating genome transcription, cell signaling, and hormone release, enhancing insulin activity.

What are the symptoms of zinc deficiency? Zinc deficiency can cause various symptoms. Here are some of the most common:

• Loss of appetite;
• Weight loss;
• Fatigue and weakness;
• Growth and development problems in children;
• Difficulty healing wounds;
• Changes in taste and smell;
• Hair loss;
• Dry, flaky skin;
• Fertility problems;
• Recurrent infections.

Who is most at risk of developing a zinc deficiency? Who should take zinc supplements?

• Children and adolescents;
• Subjects suffering from malnutrition or anorexia nervosa;
• Individuals with type I and type II diabetes, conditions that increase urinary zinc excretion;
• Individuals with chronic diarrhea or intestinal diseases characterized by inflammation and/or malabsorption such as Crohn's disease or celiac disease;
• Alcoholics, especially those suffering from liver cirrhosis;
• Athletes subjected to intense endurance work with high sweating;
• Individuals undergoing drug therapy with tetracyclines, quinolones, bisphosphonates, chelators, anticonvulsants and diuretics;
• Individuals taking iron and calcium supplements, which can significantly reduce zinc absorption;
• Strict vegans with a high intake of grains and legumes: the phytate content of these foods interferes with zinc absorption, drastically reducing it.

Is Zinc Really Helpful for Fighting Common Cold Symptoms? Zinc supplements are often used to treat cold And many studies have shown that zinc can effectively block the replication of rhinoviruses, which are responsible for approximately 50% of cold cases. Zinc interferes with the reproduction of cold viruses in the nasal mucosa, preventing their development and counteracting cold symptoms. If taken at the first symptoms, zinc can significantly reduce recovery time and cold symptoms. This has been scientifically proven in several studies.

Is it true that zinc is implicated in our reproductive health and fertility? Research has shown that the maintaining adequate zinc levels in the body can be associated with higher testosterone levels and to a better sperm health. Conversely, a zinc deficiency can cause a reduction in testosterone production in men. Studies have shown that zinc supplementation can increase serum testosterone levels, especially in men with low baseline concentrations. Even after intense physical activity, especially aerobic exercise, zinc supplementation can maintain testosterone levels, which might otherwise decline.

I've heard that zinc can also help with PCOS. Is this true? PCOS (polycystic ovary syndrome) is an endocrine condition that affects women of reproductive age and can cause hormonal dysfunction, irregular menstrual cycles, weight gain, and infertility. Several lines of evidence suggest that zinc may play a positive role in managing PCOS-related symptoms. In particular, a study published in the journal "Biological Trace Element Research" demonstrated that women with PCOS have lower zinc levels than healthy women , and that zinc supplementation may improve hormone levels and ovarian function and reduce the severity of acne. A study published in the "Journal of Research in Medical Sciences" suggested that zinc supplementation could improve lipid profile and reduce the risk of heart disease in women with PCOS and it also appears that zinc may participate in the regulation of the menstrual cycle. Serum zinc levels during the luteal phase (about 2 weeks before your period) are significantly lower than during the follicular phase, and have also been shown to be lower in women with PMS (premenstrual syndrome).
