As we age, we often turn to dietary supplements to fill the gaps in our nutrition or to bolster our health against the wear and tear of time.

It's a practice embraced by many, with around three-quarters of Americans incorporating vitamins and supplements into their daily routines.

However, a concerning trend is emerging, one that could be silently undermining the very health we seek to protect.

A doctor has stepped forward to shed light on six popular supplements that, when taken in excess, might be causing more harm than good.

The hidden dangers of too many supplements​

The body relies on balance, and while supplements can be beneficial, overuse can lead to dangerous consequences.


Excess intake of certain vitamins and minerals can result in toxicity, causing issues like liver damage, kidney failure, and nerve problems.

Since symptoms often take time to develop, some people may not realize their daily routine is harming their health.

Iron: essential but risky in large amounts​

Iron plays a key role in carrying oxygen through the blood, but too much can become toxic.

Experts say that consuming more than 20 milligrams can trigger symptoms like nausea and stomach pain.

Over time, excess iron can damage major organs, increasing the risk of heart failure, liver disease, and other serious conditions.

Calcium: good for bones, bad in excess​

Calcium is important for maintaining strong bones and muscle function, but too much can lead to hypercalcemia, in which too much calcium is circulating in the blood.

This condition can cause constipation, nausea, kidney damage, and confusion. In severe cases, excessive calcium intake has been linked to coma.

Vitamin D: too much of the sunshine vitamin​

Vitamin D supports bone health, but taking high doses for long periods can lead to toxicity.

Experts warn that excessive amounts can cause kidney failure, irregular heart rhythms, and muscle weakness.

Unlike sunlight exposure, which won’t cause an overdose, supplements can build up in the body over time.

Vitamin A: crucial but dangerous in large doses​

Vitamin A is needed for vision, immunity, and growth, but too much can lead to severe health issues.

Experts say consuming more than 3,000 micrograms can result in dizziness, liver failure, and weakened bones.

Pregnant women are advised to be extra cautious, as excess vitamin A has been linked to birth defects.

Magnesium: a mineral with hidden risks​

Magnesium is important for heart and muscle function, but taking too much can lead to diarrhea, low blood pressure, and even coma.

Those with kidney or heart conditions are especially at risk, as their bodies may struggle to remove excess amounts.

Folic acid: helpful but not always safe​

Folic acid is recommended for pregnancy, but high doses can mask a vitamin B12 deficiency.

This can lead to nerve damage, digestive problems, and other health concerns.

Experts emphasize the importance of sticking to recommended amounts:

• Recommended daily dose for adults: 400 micrograms
• Recommended daily dose for pregnant women: at least 600 micrograms

Moderation is key when it comes to supplements.

It’s important to follow recommended dosages and consult a healthcare provider before making any changes to your routine.

Be aware of potential risks and pay attention to any unusual symptoms that may signal an issue.
