The One Supplement You Should Be Taking Every Morning To Speed Up Your Metabolism Over 40, According To Experts

That's where supplements come into play. Experts say that introducing a daily supplement into your routine can significantly improve your metabolism by giving it the natural boost it needs to burn calories efficiently. 

In fact, there's one in particular that nutritionist Ann Louise Gittleman, Ph.D., CNS, suggests taking for weight loss over 40--it's gamma-linolenic acid (GLA)!

"GLA is unparalleled in promoting fat burning by activating a type of fat called brown fat," she tells BetterNutrition.com. 

In addition to taking a GLA supplement, other fitness experts say that a daily probiotic can also help improve metabolic function as they promote a healthy digestive system. 

“I’m a big fan of soil-based organism (SBO) probiotics, which mimic the natural beneficial bacteria found in soil that our ancestors used to ingest in small amounts on unwashed veggies from the garden,” Snyder explains. 

Make sure you talk to your doctor before adding any of these supplements into your weight loss routine!
