Dietary Supplements: Advantages, Side Effects and Things To Know

This article will explore some common dietary supplements’ benefits and risks and what you need to know.

What are the Advantages of Dietary Supplements?

Most people can get all the nutrition they need by eating a healthy, balanced diet. However, some are prone to deficiencies and must add nutrients to their diets in the form of supplements. High-risk groups include older adults, those with chronic medical conditions, pregnant people, and individuals who follow special diets, such as vegans.

Many people also take supplements believing they will improve their health and help prevent conditions like heart disease, osteoporosis and cancer. Some of the most popular dietary supplements include:

  • Ikaria Lean Belly Juice.
  • Alpilean Supplement.
  • B vitamins.
  • Vitamin C.
  • Vitamin D.
  • Calcium.
  • Iron.
  • Herbal remedies, such as St. John’s wort and ginkgo.
  • Probiotics.
  • Fish oils.
  • Glucosamine.

Some of these supplements’ benefits are well-known. For example, vitamin B12 is necessary for healthy nerves, and blood cells, calcium and vitamin D keep the bones strong and omega-3 fish oils play a role in protecting the heart.

However, many supplements do not have enough evidence to support their use. Furthermore, the Food and Drug Administration (FDA) does not recognize them as medicines. Therefore, supplement manufacturers cannot claim their products to cure, treat or prevent any specific disease. They can only state that their supplements may help support certain health aspects.

The Risks and Side Effects

More than 50% of Americans take dietary supplements daily or occasionally. These include vitamins, minerals, amino acids, herbs, probiotics and other products like fish oils and glucosamine.

These supplements have many potential benefits, and most are considered safe. However, some can cause side effects, especially when taken in high doses or used alongside other medicines.

Many people assume that dietary supplements are safe. However, this is not necessarily true and some supplements can cause serious side effects.

These side effects are most likely to occur when people take high doses, combine several different supplements, mix them with other medicines, or substitute supplements for prescribed medication.

Here are some of the possible side effects of popular dietary supplements:

Ikaria Lean Belly Juice

This supplement is an effective weight loss diet supplement made up of effective ingredients that can aid in you losing weight; helping you shed belly fat and excess weight. All ingredients are pure, natural, and carefully sourced.

Alpilean Supplement

Vitamin A

Taking too much vitamin A can cause headaches, reduce bone strength, and damage the liver. Taking vitamin A supplements while pregnant can cause birth defects.

Vitamin B6

Taking high doses of vitamin B6 for extended periods can cause nerve damage. This supplement can also interact with some medications, reducing their effectiveness.

Vitamin C

Vitamin C is relatively safe, but when taken at very high doses, the body cannot absorb it, leading to diarrhea. It can also reduce the effectiveness of chemotherapy drugs that are used to treat cancer.

Vitamin E

Vitamin E supplements have been linked with an increased risk of prostate cancer. They can also reduce the effectiveness of chemotherapy drugs.

Vitamin K

Vitamin K affects blood clotting and supplements can interact with blood-thinning drugs like warfarin.


Eating a calcium-rich diet is thought to protect the cardiovascular system. However, calcium supplements have been linked with an increased risk of heart disease.


Iron supplements can cause digestive symptoms, such as nausea, vomiting, and constipation. They could also damage the liver and other organs when taken in high doses for a long time.

St. John’s Wort

St. John’s wort interacts with many different medications. It causes the body to break down the other drugs more quickly and reduces their effectiveness.


Ginkgo supplements can interact with blood thinners like warfarin, increasing their effects on the body.

Fish Oils

Fish oil supplements can cause digestive side effects, such as nausea, heartburn, and diarrhea. They may also cause bad breath or a fishy taste in the mouth.
