Dietary Sources Zinc is best absorbed when taken with a meal that contains protein. The best sources of zinc are oysters (richest source), red meats, poultry, cheese (ricotta, Swiss, gouda), shrimp, crab, and other shellfish.
Amino acids, such as histidine and methionine, and other low-molecular-weight ions, such as EDTA and organic acids (e.g., citrate), are known to have a positive effect on zinc absorption and have been used for zinc supplements.
Sources of Zinc. The richest food sources of zinc include meat, fish, and seafood [3]. Oysters contain more zinc per serving than any other food, but beef contributes 20% of zinc intakes from food in the United States because it is commonly consumed [7]. Eggs and dairy products also contain zinc [3].
It's challenging for the body to efficiently absorb zinc on its own because it tends to interact with other substances that impact absorption. However, chelated zinc is highly absorbable.
People who drink excessive alcohol can also not absorb zinc normally. Long-term illnesses, such as chronic liver or kidney disease can also result in low absorption of zinc. High-dose iron supplements can also affect the way zinc is absorbed, leading to deficiency.
Vitamin D could also induce zinc transporters to regulate zinc homeostasis. Together, zinc and vitamin D in adequate concentrations help maintain a healthy musculoskeletal system and beyond; however, deficiency in either of these nutrients can result in various disorders affecting almost all body systems.
Taking these two nutrients together gives a joint boost to your immune system. Additionally, vitamin C contains ascorbic acid, which is thought to help with zinc absorption – though studies have not found conclusive results yet.
Caffeine may reduce the absorption of manganese, zinc and copper. It also increases the excretion of the minerals magnesium, potassium, sodium and phosphate. There is also evidence that caffeine interferes with the action of vitamin A.
Usually, zinc replacement therapy is continued for 3–4 months. If initiated within 6 months after the onset of zinc deficiency, the response rate to this therapy (the percentage of cases where the therapy is effective or markedly effective) is 70% or higher.
The best source of zinc is oysters, but it's also plentiful in red meat and poultry. Other good sources are beans, nuts, crab, lobster, whole grains, breakfast cereals, and dairy products.
Magnesium helps your body to regulate its zinc levels, while zinc enables your body to absorb magnesium more efficiently. It is important that you keep your dose of zinc below 50mg per day because it can disrupt the magnesium absorption with larger doses.
According to a 2011 review , zinc may improve signs of depression or mood disorder because it helps reduce inflammation, inhibiting brain function and cognitive performance.
Immunosuppressant medications -- Since zinc may make the immune system stronger, it should not be taken with corticosteroids (such a prednisone), cyclosporine, or other medications intended to suppress the immune system.
Vitamin D could also induce zinc transporters to regulate zinc homeostasis. Together, zinc and vitamin D in adequate concentrations help maintain a healthy musculoskeletal system and beyond; however, deficiency in either of these nutrients can result in various disorders affecting almost all body systems.
When taking Vitamin C and Zinc, there is no reason to worry about anything going wrong for taking the two together. They both are great vitamins and minerals that help with immune function in a synergistic relationship.
Because zinc affects so many systems in the body, there is no single distinct symptom of zinc deficiency. Some of the more common symptoms include loss of or diminished smell and taste, poor wound healing, hair loss, roughening of skin/rashes, low libido (men), canker sores, lethargy, and deformed nails.
Zinc deficiency in humans is caused by reduced dietary intake, inadequate absorption, increased loss, or increased body system use. The most common cause is reduced dietary intake.
Blood testing instead of the oral challenge:
You can also get a blood test to determine your zinc levels. This can be done at your doctors office or at our office.
Magnesium helps your body regulate its zinc levels, while zinc enables it to absorb magnesium more efficiently. Zinc will only hinder absorption when taken in abnormally high doses (around 142 mg of zinc per day).
Although bananas are rich in carbohydrate, fiber, protein, fat, and vitamins A, C, and B6 they are largely deficient of iron (Fe), iodine, and zinc (Zn).
A study at the University of Toronto showed that zinc has a key role in regulating how neurons communicate. A lack of zinc can lead to foggy thinking and memory problems. Because zinc is so important to cognitive function, zinc supplementation has also been successful in improving the symptoms of ADHD.
