Do Multivitamins really Work? 

Multivitamins are supplements that contain many different vitamins and minerals, sometimes alongside other ingredients .Trusted Source

Given that there’s no standard for what constitutes a multivitamin, their nutrient composition varies by brand and product 

Multivitamins are also referred to as multis, multiples, or simply vitamins.

They’re available in many forms, including tablets, capsules, chewable gummies, powders, and liquids.

Most multivitamins should be taken once or twice per day. Make sure to read the label and follow the recommended dosage instructions.

Multivitamins are available in pharmacies, large discount stores, and supermarkets, as well as online.

Many produce enzymes and hormones, boost your immunity, and keep your nerves and organs functioning properly 

Your body also needs these nutrients for reproduction, maintenance, growth, and the regulation of bodily processes.

Multivitamins may offer many of these vitamins and minerals — but in varying amounts. They may also contain other ingredients like herbs, amino acids, and fatty acids.

Because the Food and Drug Administration (FDA) doesn’t regulate dietary supplements as strictly as it regulates prescription drugs, some may contain higher or lower levels of some nutrients than stated on the label.

Additionally, some supplements may contain ingredients that can interact with medications, so speak with your healthcare provider before starting a new supplement 

Furthermore, the nutrients in multivitamins may be derived from real foods or made synthetically, making it essential to purchase your vitamins from a reputable manufacturer.

Brain function

Several small studies examining specific populations have found that multivitamins can improve memory in older adults .

Multivitamins may also affect your mood. Research has not only revealed links between poor mood and nutrient deficiencies but also between nutritional supplements and reduced symptoms of anxiety and depression 

However, other studies reveal little to no changes in mood 

Eye health

Age-related macular degeneration is one of the leading causes of blindness worldwide Trusted Source

One study found that taking antioxidant vitamins and minerals may slow its progression and help prevent it 

Furthermore, some evidence indicates that multivitamins may reduce your risk of developing cataracts, another widespread eye disease .

Multivitamins aren’t right for everyone and may even harm some individuals.

That said, specific populations may benefit from multivitamins, including:

• Older adults. Vitamin B12 absorption can decrease with age. Also, older adults may need more calcium and vitamin D .
• Vegans and vegetarians. As vitamin B12 is found primarily in animal foods, those who follow plant-based diets are at a higher risk of deficiency of this vitamin. They may also lack calcium, zinc, iron, vitamin D, and omega-3 fatty acids.

Other people who may benefit from multivitamins include those who’ve undergone weight loss surgery, are on low calorie diets, or don’t get enough nutrients from food alone .

it’s best if you don’t take a multivitamin to compensate for a poor diet. Eating a balanced diet of fresh, whole foods is much more likely to ensure good health over the long term.
