When it comes to taking supplements, moderation is key. Combining several supplements or taking doses higher than recommended may increase the risk of harm, so it's important to be aware of potential interactions. Fortunately, in most cases, it's safe to take multiple vitamins at once. However, if you're not sure if there's an interaction, contact your healthcare provider. Vitamin C helps the absorption of iron, so it's OK to take multiple vitamins at once.
Kitchin also recommended calcium and vitamin D supplements to some patients at risk of osteoporosis, but he always analyzes their diet first before prescribing them. Unfortunately, the answer isn't black or white, since, in some cases, you can take all the supplements at once, while in others you can't.In light of these and other studies, most experts say that dietary supplements aren't all they were intended to be. However, some studies show no evidence that many popular supplements have real health benefits, leading many scientists to change some of their recommendations. You should also administer any new supplement you're considering with your provider or pharmacist before adding it to your regimen. Rather than trying to figure out which supplements are safe to take together on your own, work with a nutritionist, dietician, or health professional who specializes in dietary supplements to help clear up the confusion.
Not only can supplements help avoid a deficiency of a certain nutrient, but they can also help increase levels of certain nutrients faster than food sources alone. This is important because a supplement meant to help you sleep, for example, is generally not something you want to take during the day. It's not a good idea to take an iron supplement (or eat iron-rich foods) at the same time as green tea. David Jenkins also said that, when taken in moderation, most vitamin and mineral supplements cause no harm. If you are taking zinc, it is recommended that you also take a 2 mg copper supplement to maintain the balance of these two minerals in the body. Whether you're taking a daily multivitamin to improve your overall health or you're relying on herbal supplements to fill nutritional gaps, it's important to be aware of potential interactions.
Moderation is key when it comes to taking supplements and consulting with a healthcare professional can help ensure that you're taking the right ones for your needs.
