Magnesium Zinc And Calcium Together

Supplements That Should Not be Taken Together

All three of these minerals are common additions to multivitamin supplements that promote the all-encompassing, one-a-day philosophy. The problem with taking magnesium, zinc, and calcium together is that theyre all attempting to be absorbed by your body the same way. They compete, and in that competition, a significant portion of each mineral may be lost.

If youre supplementing with all three of these minerals, its better to take them in low doses and spread them out over the course of the day. Taking one with each meal will ensure that each mineral has had a chance to absorb before the other is consumed.

Large Doses Of Minerals Can Also Lead To Health Problems

  • At just 5 times the RDI, zinc, iron, chromium and selenium can be raised to toxic levels in the body.
  • Large intakes of fluoride may stain, and even weaken, the teeth.
  • Very large doses of fish oil can lead to decreased blood clotting.
  • Iron toxicity is also common. Even a small amount over the RDI can cause gastrointestinal upset, nausea and black bowel actions . Severe toxicity can lead to coma and even death.

Other Supplement Combinations To Avoid

Copper and zinc

Both copper and zinc are important minerals. Most people get enough of these nutrients through their diet. Copper helps with brain development, nervous system health, and in making important tissues in the body. Zinc is an important mineral for healing.

Different minerals can compete for absorption in your digestive system when taken at the same time. So, if you take copper and zinc together, one usually has poor absorption. In the case of these two supplements, zinc wins. People who take a lot of zinc supplements may develop a copper deficiency.

One source of zinc supplementation is denture cream. If you use denture cream and experience neurological problems, you may have a copper deficiency.

Green tea and iron

On their own, both of these supplements offer a lot of benefits. Green tea has anti-inflammatory compounds that may help people with conditions like inflammatory bowel disease. Iron is important for making hemoglobin, a protein in your blood.

However, when taken together, the antioxidants from green tea bind to iron. This lessens the positive effects of consuming green tea.

Calcium with other minerals

Calcium is an important mineral for bone health. Taking a calcium supplement can affect how your body absorbs other minerals including zinc, magnesium, or iron. If you take any combination of these supplements, talk to your doctor about the best timing for maximum absorption of each mineral.

Brain Specific Roles Of B Vitamins

The brain is by far the most metabolically active organ in the body, representing only 2% of body weight but accounting for over 20% of the bodys total energy expenditure . The B vitamins general metabolic functions, alongside their roles in neurochemical synthesis, may therefore be conceived as having a particular impact on brain function. Indeed, the importance of the B vitamins for brain function is illustrated by the fact that each vitamin is actively transported across the blood brain barrier and/or choroid plexus by dedicated transport mechanisms. Once in the brain, specific cellular uptake mechanisms dictate distribution, and, whilst the B vitamins all have high turnovers, ranging from 8% to 100% per day, their levels are tightly regulated by multiple homeostatic mechanisms in the brain . This guarantees that brain concentrations remain comparatively high. For example, the concentration of methyltetrahydrofolate in the brain is four times that seen in plasma , whereas biotin and pantothenic acid exist in the brain at concentrations of up to 50 times that seen in plasma .

Do We Need To Take Vitamins

While we should rely primarily on a healthy, balanced diet to support good health, sometimes we might need to take a vitamin supplement in order to ensure that we are getting enough of a vitamin. This is of particular concern if you have one of the most common vitamin deficiencies.

Dr. Sarah Brewer, a GP and Medical Director of Healthspan tells us more about why you might want to take a vitamin supplement. By definition, vitamins are essential for life as we cannot make them all in the body or in sufficient amounts to meet our needs , she says. Diet should always come first, but the National Diet & Nutrition Studies show that significant numbers of people do not get all the micronutrients they need from their food. A multivitamin then acts as a nutritional safety net.

A review carried out by the Agency for Healthcare Research and Quality indicated that multivitamin and mineral supplements might help reduce the risk of cancer development in malnourished individuals, however, this very rarely applies in the USA.
