Yes. Vitamins and minerals all work in combination and rely on each other to be fully effective. Taking magnesium supplements helps your body to absorb and use types of minerals such as calcium, phosphorus and potassium, and vitamins like vitamin D.
No interactions were found between potassium chloride and Vitamin D3. However, this does not necessarily mean no interactions exist. Always consult your healthcare provider.
Can you take vitamin D and magnesium together? Yes. In fact, it's probably best to take both together. Because so many people have low magnesium levels, vitamin D supplements on their own aren't very helpful for a large portion of the population.
Both minerals also work synergistically together to improve mood and reduce the risk of mental health conditions. Therefore, you can rest assured there is no problem with combining these nutrients.
If You Take Mineral Supplements
Large doses of minerals can compete with each other to be absorbed. Don't use calcium, zinc, or magnesium supplements at the same time.
Magnesium can decrease the absorption and effectiveness of numerous medications, including some common antibiotics such as tetracycline (Achromycin, Sumycin), demeclocycline (Declomycin), doxycycline (Vibramycin), minocycline (Minocin), ciprofloxacin (Cipro), levofloxacin (Levaquin), moxifloxacin (Avelox) and ofloxacin ...
Take potassium and magnesium supplements right after meals or with food. Follow the label on how often to take it. The number of doses you take each day, the time between doses, and how long you take it will depend on which medicines you were prescribed and your condition.
Magnesium deficiency is diagnosed via a blood test and sometimes a urine test. Your doctor may order the blood test if you have symptoms such as weakness, irritability, abnormal heart rhythm, nausea and/or diarrhoea, or if you have abnormal calcium or potassium levels.
Magnesium has always been touted as the super mineral for sleep, but recent research suggests that its friend, potassium, may be just as beneficial—and this is why swapping your morning potassium supplement for the evening might be ideal.
Adequate levels of magnesium in the body are necessary for the absorption and metabolism of vitamin D, important for maintaining healthy bones and teeth and supporting the body's immune system, brain and nervous system.
So, get enough vitamin D—just take it in the morning or afternoon. At night, take supplements that support sleep quality and muscle relaxation, like magnesium and melatonin (which you'll find in soothing, sippable Bulletproof Sleep Collagen Protein).
Certain medications (bile acid sequestrants such as cholestyramine/colestipol, mineral oil, orlistat) can decrease the absorption of vitamin D. Take your doses of these medications as far as possible from your doses of vitamin D (at least 2 hours apart, longer if possible).
You should not take this medicine if you are also using atropine, benztropine (Cogentin®), glycopyrrolate (Robinul®), or a diuretic or "water pill" (such as amiloride, spironolactone, triamterene, Aldactone®, Dyrenium®, or Midamor®). Using these medicines together may cause serious problems.
Aluminum. Taking vitamin D and aluminum-containing phosphate binders, which may be used to treat high serum phosphate levels in people with chronic kidney disease, might cause harmful levels of aluminum in people with kidney failure in the long term.
For example, potassium decreases urinary calcium excretion and increases body calcium balance, probably by increasing renal calcium resorption. Magnesium administration, concomitant with potassium, assists tissue replenishment of potassium.
Potassium repletion
Always check the serum magnesium level and replete magnesium prior to repleting potassium. Low magnesium can exacerbate renal potassium losses.
Combining multiple supplements or taking higher-than-recommended doses can increase the risk that they can cause harm, said Kitchin.
