As mentioned, zinc is an essential cofactor to have the desired functions of vitamin D. Similarly, vitamin D can also influence zinc absorption and homeostasis by regulating its transporters.
Be Careful With Supplements
Iron, copper and calcium supplements may compete with zinc for absorption, so only take these if prescribed by a doctor or take them at a separate time from when you consume foods rich in zinc.
Phytate, which is present in staple foods like cereals, corn and rice, has a strong negative effect on zinc absorption from composite meals.
Phytate, which is present in staple foods like cereals, corn and rice, has a strong negative effect on zinc absorption from composite meals. Inositol hexaphosphates and pentaphosphates are the phytate forms that exert these negative effects, whereas the lower phosphates have no or little effect on zinc absorption.
Medications including penicillamine, various diuretics, certain antibiotics, and sodium valproate can inhibit absorption as well. Acrodermatitis enteropathica is an inherited form of zinc deficiency from impaired absorption.
that combine the two. 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).
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.
Interactions between your drugs
No interactions were found between Vitamin D3 and Zinc.
Phenobarbital, phenytoin, and other anticonvulsant medications -- These medications may accelerate the body's use of vitamin D. Mineral oil -- Mineral oil also interferes with absorption. In addition, Vitamin D may enhance the effects of doxorubicin , a medicine used to treat a variety of cancers.
Try taking it alongside breakfast or with a bedtime snack — as long as it doesn't interfere with your sleep. The key is to find what works for you and stick with it to ensure you're meeting your vitamin D needs. Taking vitamin D with a meal can increase its absorption, but studies on specific timing are limited.
Steroids. Taking steroid mediations such as prednisone can reduce calcium absorption and impair your body's processing of vitamin D. Stimulant laxatives. Long-term use of high doses of stimulant laxatives can reduce vitamin D and calcium absorption.
Do not take zinc supplements and copper, iron, or phosphorus supplements at the same time. It is best to space doses of these products 2 hours apart, to get the full benefit from each dietary supplement.
Additionally, vitamin C contains ascorbic acid, which is thought to help with zinc absorption – though studies have not found conclusive results yet.
Can Magnesium And Zinc Be Taken Together? Absolutely! In fact, they should be taken together. Minerals and vitamins are all competing for your body's ability to absorb them, so they need certain conditions for the best effect.
They can work together, boosting and enhancing absorption, or sometimes work against each other, competing for absorption. Zinc and magnesium are synergistic minerals that work together when taken at the right dosages.
Our findings suggest that high-calcium diets can reduce net zinc absorption and balance and may increase the zinc requirement in adult humans.
If you are taking zinc, the following foods should be avoided or taken 2 hours after you take zinc: Bran. Fiber-containing foods. Phosphorus-containing foods such as milk or poultry.
Folate. The bioavailability of dietary folate (vitamin B9) is increased by the action of a zinc-dependent enzyme. Accordingly, some studies found low zinc intake decreased folate absorption.
Studies looking at zinc's potential to help shorten or reduce the intensity of colds or other respiratory illnesses have involved daily doses of up to 100 mg, but just for the duration of the illness.
We recommend taking it with a source of quality fat in the morning or when you break your fast. Avoid taking vitamin D in the evening (we'll talk about why below). Since vitamin D is a fat-soluble vitamin—meaning it doesn't dissolve in water—your body can most easily absorb it when you take it with food.
Too much vitamin D can cause calcium to accumulate in your blood, which can damage your heart, blood vessels, and kidneys.
But vitamin D is a 'fat-soluble' vitamin, so your body can store it for months and you don't need it every day. That means you could equally safely take a vitamin D supplement of 20 micrograms a day or 500 micrograms once a month. Don't worry - your doctor or pharmacist aren't trying to poison you!
You can—but it's probably not a good idea. For some supplements, optimal absorption can depend on the time of day taken. Not only that—taking certain vitamins, minerals, or other supplements together can also reduce absorption and may result in adverse interactions, which can be harmful to your health.
Is there a benefit to taking vitamin D at night? There's been some buzz suggesting a link between supplementing with vitamin D before bedtime and the ability to drift off to dreamland. Some studies have shown that vitamin D is connected to the production of melatonin, which regulates circadian rhythm and drives sleep.
