How to benefit from taking vitamins and dietary supplements?

SadaNews - While most people get enough nutrients from their diet, certain factors may interfere with some others' ability to obtain the necessary nutrition, and they may benefit from vitamin supplements.

Dietary supplements work best when they meet specific health needs. You may benefit from using vitamins and supplements if you do not get specific vitamins or nutrients from your normal diet, or if the nutrients you obtain are affected by health issues, medications you are taking, or other factors. Some of the people who may benefit from supplements include:

Pregnant women

Folic acid supplements can reduce the risk of neural tube defects in the fetus, such as spina bifida, according to the "Verywell Health" website.

Vegetarians and celiac disease patients

Individuals following certain diets, such as vegetarians and those with celiac disease, may benefit from multivitamin supplements that include essential nutrients such as iron, vitamin D, copper, zinc, and vitamin B12. Those who avoid certain food groups due to lifestyle or food allergies may also benefit from supplements to compensate for nutrients they lose from foods.

Patients with heart disease, cancer, and diabetes

Individuals with specific health problems may benefit from certain vitamins and minerals. For example, people with osteoporosis may find relief from taking calcium and vitamin D supplements. Additionally, those with conditions such as heart disease, cancer, diabetes, HIV or AIDS, or some autoimmune diseases may also benefit from certain vitamins and minerals.

Seniors

They may benefit from vitamin D, vitamin B12, and calcium supplements as their ability to absorb and process these nutrients decreases with age. People suffering from age-related macular degeneration (AMD) or those at risk of developing it may benefit from vitamin A, which can help slow the loss of vision.

How can you help dietary supplements work effectively?

Vitamins and supplements are more effective when taken as directed, at the recommended dosage from your doctor, or according to the instructions on the product label.

When do dietary supplements stop working?

Several factors can affect how vitamins and dietary supplements work and the benefits you gain from taking them.

Vitamins may stop working in the following cases:

If the supplement is not taken at the right time

For maximum absorption, some supplements need to be taken at specific times of the day or with certain foods. For example, fat-soluble vitamins, which include vitamins A, D, E, and K, are absorbed better when taken with a meal containing fats.

Taking too many supplements

You may be taking large doses of calcium or another mineral at the same time with other nutrients, reducing the absorption of the lower-dose nutrients.

Medications can interfere with supplements

You may be taking some medications that affect your ability to absorb and utilize nutrients.

You may suffer from malabsorption syndrome

This can occur due to damage to the small intestine that hampers your ability to absorb nutrients.

If you haven’t taken them for long enough

You may not have taken vitamins or supplements for long enough to see improvement in your symptoms. Water-soluble vitamins, including vitamin C and all B vitamins, are absorbed more easily and may give faster results than fat-soluble vitamins, which require fats for optimal absorption.

What are the risks of overdosing on vitamins and dietary supplements?

It’s easy to think that taking more vitamins means better health, but this is not true. Excess consumption beyond your body’s needs can lead to "vitamin poisoning," causing side effects ranging from mild discomfort to serious health problems.

Signs that you may be taking too many dietary supplements

Excessive supplement intake can disrupt your body’s balance. Common symptoms of vitamin overdose include: nausea or vomiting or diarrhea, fatigue or muscle weakness, bone and joint pain, skin irritation, stomach pain or liver problems, frequent urination or cloudy urine, or irregular heartbeat.

If you experience these symptoms, talk to your doctor before continuing to take supplements.

What happens when overdosing on certain vitamins?

Taking high doses of specific vitamins or minerals for a long time can lead to more serious health problems, for example:

Excessive intake of vitamin A

Overconsumption of vitamin A can lead to headaches, liver damage, bone density loss, and an increased risk of birth defects (which is especially concerning for smokers).

Excessive intake of iron supplements

Excessive intake of iron supplements can cause nausea, vomiting, and the potential for liver or other organ damage.

Excessive intake of vitamin B6 and B12

Excessive intake of vitamins B6 and B12 may increase the risk of hip fractures in postmenopausal women.

Excessive intake of vitamin D

Excess intake of vitamin D can significantly raise calcium levels in the blood, leading to fatigue, nausea, or confusion.

Excessive intake of vitamin K

Excess intake of vitamin K may interfere with blood thinners like Coumadin (warfarin).
