Key Takeaways

  • Magnesium and collagen are important for joint and skin health.  
  • There is no research showing extra benefits from taking magnesium and collagen together, but they are safe to take at the same time.  
  • Be careful of heavy metals in collagen supplements and try to get these nutrients from whole foods.  

Your body needs both magnesium and collagen, as both play a role in maintaining joint and skin health, and regulating stress and recovery. Taking the supplements together may provide some added benefit, though we don’t currently have research that supports this.

Magnesium May Lower Inflammation in the Joints

Magnesium supplements and their uses vary widely.

“There are different forms of magnesium that work on different areas of the body,” Samantha Dieras, DCN, RD, CDN, director of ambulatory nutrition services at Mount Sinai Health System, told Verywell. 

“For example, magnesium citrate can be used as a laxative, magnesium glycinate for sleep, and magnesium L-threonate for memory,” she said.

However, one use involves the joints. “Magnesium stops cartilage from turning into bone and lowers inflammation in the joints,” Erik Modlo, MD, a functional medicine physician at Cleveland Clinic, told Verywell.

Collagen May Improve Joint Mobility and Decrease Pain

Collagen affects your skin and your joints. “Collagen gives the body the structural parts that make the skin more flexible and less painful,” Modlo said.

Collagen supplements can boost your health in multiple ways. “Some studies support collagen supplementation in improving skin elasticity, improving joint mobility, and decreasing joint pain,” Dieras said.

Combining the Two May Offer Extra Benefits

Currently, there is no research showing that taking both magnesium and collagen will boost skin and joint health even more. “Still, both supplements are safe to use together and help skin and joint health in different ways,” Modlo said.

Though it’s safe to take magnesium and collagen supplements together, you should make sure you’re taking an appropriate dose. “It is important to understand all of the ingredients within the products you’re taking to avoid over-consuming a particular nutrient,” Dieras said.

You should be careful about collagen supplements, in particular. “There is additional concern for heavy metals within collagen supplements,” Dieras said.

As with any nutrients you’re not getting enough of, it can also be helpful to get more collagen and magnesium through your diet. “With all of these nutrients, it is best to primarily consume them in whole foods,” Dieras said.
