Taking dietary supplements has become commonplace nowadays. Every other person is taking them, and their ease of availability and access makes them a convenient choice for people who believe they are safeguarding their health – often without a healthcare professional’s guidance.

However, consulting your healthcare provider is essential before taking these supplements. This is because while dietary supplements may be beneficial to your health, they may also bring with them some health risks. Understanding what they are is essential to make informed decisions.

What Are Dietary Supplements?

As the name suggests, dietary supplements are intended to complement your diet with nutrients that may already bepresent in your food.Supplements come in various forms – tablets, capsules, gummies, powders, etc. and are generally available over-the-counter in India, which means you do not need a prescription to purchase them.

People often supplement with vitamins, minerals, iron, calcium, folic acid, and other herbal and plant-based extracts.

Ideally, your diet should provide you with all the nutrients you need. When this is not possible, supplements can be used but with guidance from a doctor.

When Do Doctors Prescribe Supplements?

Dietary supplements may boost immunity and minimize the risk of developing some health conditions. Doctors usually prescribe them under the following circumstances:

• When the risk of developing a health condition (like osteoporosis or anemia) can be lowered by adding a supplement.
• During pregnancy or while nursing when the mother needs extra nutrients.
• When some health conditions make it difficult for the body to absorb nutrients.
• When a special diet does not give necessary nutrients.
• When there are signs of malnourishment.
• When laboratory tests reveal deficiency of nutrients.
• When older adults cannot absorb nutrients from food.

Signs of Deficiencies

If you experience any of the following symptoms, your diet might be lacking some nutrients.

• Significant hair loss
• Bone or joint pain
• Extreme fatigue
• Abnormal heart beat
• Altered vision
• Wounds that take time to heal

In such cases, let your doctor know immediately. He will recommend investigations to confirm any deficiencies. In India, deficiencies of vitamins D and B12, iron, calcium and zinc are commonly reported.

Busting 5 Common Myths

Myth 1: Everyone should take dietary supplements.

Fact: This is a widely held misconception. Health experts recommend that dietary supplements be taken only when there is a need. As already mentioned, it is best to get the necessary nutrients from food rather than tablets as food provides a mix of nutrients and fibre that no supplement can replace.

Myth 2: Dietary supplements come from natural sources. Hence, they are safe.

Fact: We cannot take safety of supplements for granted. There are also artificial supplements available which are made to mimic properties of natural ones. Further, even natural supplements are processed into the form in which we consume them. Whenever we process anything, it loses some of its natural qualities.

Myth 3: More supplements = better health.

Fact:This is a dangerous misconception. Increased supplement consumption, more than what the body needs, can backfire. Sometimes, excess amounts are simply be excreted by the body, as with vitamin B. But other compounds can accumulate and harm the body. For example, excessive vitamin B6 can impair nerve function; high levels of vitamin D can cause harmful calcium imbalances and related complications; too much omega-3 can result in abnormal heart beat, and so on.

Myth 4: Supplements can be taken safely along with other drugs.

Fact: Some supplements may interact with drugs and can reduce effectiveness, increase side-effects, or even harm the body. For example, St. John’s wort, fish oil and garlic can interfere with blood thinners; St. John’s wort can also reduce the effectiveness of anti-depressants and other drugs.

Myth 5: The efficacy of all supplements has been proven.

Fact:While the effectiveness of certain supplements (including, but not limited to) omega-3 for heart health, vitamin D for bone health, and folic acid for prenatal health have been scientifically supported, many other supplements have not been proven to provide clear benefits.

Overconsumption of Supplements: Signs to Watch Out For

Overconsumption is a serious risk when people take supplements without medical guidance. The following are some signs of supplement overdose.

• Gastrointestinal signs like vomiting, nausea and constipation are the first indicators of overconsumption. For example, overdosing on magnesium can lead to diarrhea.
• Tiredness or dizziness can be caused by an excess of iron or vitamin A as it can lead to imbalances in the body.
• Oversupplementation of vitamin A can also cause skin irritation and hair loss.
• Frequent headaches and migraines could be triggered by an increase in vitamin B6, niacin or pre-workout supplements.
• A common sign of excess zinc is a metallic taste in the mouth.
• Certain supplements which claim to promote weight loss may cause palpitations.
• High levels of vitamin D can result in hypercalcemia which can manifest as bone pain along with mental symptoms like confusion.

Tips for Safe Supplement Use

• Always get your healthcare provider’s advice before you start any supplement. This is especially important for pregnant and nursing women, and for people with chronic health conditions. Be sure to reveal all the medicines you are taking so that your doctor gets the real picture.
• Do not self-diagnose yourself with deficiencies. Make sure to get relevant investigations to confirm them.
• Beware of products that promise “miracle” results. Always read the full ingredient list before purchasing supplements.
• Store the supplements as per the instructions given and keep an eye on the expiry date.
• If you experience side-effects after starting supplements, stop them and consult your doctor immediately.
