Don't take zinc supplements and copper, iron, or phosphorus supplements at the same time. It's best to space the doses of these products 2 hours apart to get the full benefits of each dietary supplement. Fortunately, there are no harmful side effects, however, Dr. Airey states that “it's simply not efficient to take them together, as the body's ability to absorb vitamins will be reduced if taken together.” If you're taking copper supplements because of a copper deficiency, avoid taking zinc at the same time, says Dr.
If you must take both, take them at least two hours apart. Zinc is usually part of multivitamins, but it can also be taken alone or in combination with vitamin C. It is most effectively absorbed on an empty stomach, but it can cause stomach discomfort. In this case, it should be taken with a meal and therefore not late at night.
Zinc competes with iron and calcium for absorption, so the recommendation is taken in foods that do not contain dairy products. However, some studies have shown that vitamin C could break down vitamin B12 in the digestive tract, reducing the absorption of B12. On the other hand, a study has shown that an overdose of vitamin D and calcium can increase the risk of stroke. Nighttime is not the best time because vitamin C is acidic and can cause problems when consumed on an empty stomach, especially in people with gastroesophageal reflux; of course, the dose is important. Another reason is that some vitamins are fat-soluble (A, D, E and K) and should be taken with meals for better absorption, but eating large meals at night is not recommended.
In a major clinical trial, the Age-Related Eye Diseases Study (AREDS), it was found that people with macular degeneration could delay damage by taking zinc (80 mg), vitamin C (500 mg), vitamin E (400 mg), beta-carotene (15 mg) and copper (2 mg). Multivitamins should be taken early in the day because, in addition to containing B vitamins, they can also contain other molecules that provide energy, such as caffeine, green tea extract and coenzyme Q10. Vitamin D improves calcium absorption and, therefore, both should be taken at approximately the same time. Taking vitamin D supplements at night, when you normally need to increase levels of melatonin, can affect sleep quality. Liposomal dietary supplements The market for nutritional supplements is growing rapidly, but many active ingredients (vitamins, minerals, etc.) Another reason why it's not good to take calcium at night is because vitamin D must be combined with full meals.
Research has shown that micronutrients are essential for immune function, especially vitamins A, C, D, E, B6, B12, folic acid, selenium and zinc. Vitamins and their metabolites, as well as trace elements, are essential substances for a large number of physiological processes, fulfilling various functions such as hormones and antioxidants.
