What are vitamins and minerals?

Vitamins and supplements are designed to fill gaps in nutrition, especially for those that aren’t meeting dietary requirements from food alone. Coming mostly from food, vitamins are essential organic compounds that help us sustain healthy lifestyles.

Each vitamin has a unique purpose in our bodies, and they all work together to ensure we are happy and healthy. Most vitamins and supplements can be found in a balanced, healthy diet, and adding supplements should never be a substitute for eating healthy. However, these supplements can help those with deficiencies get back on track.

Some studies also report that vitamins have the potential to improve joint health, put off the onset of Alzheimer’s, or manage other symptoms of illness. However, keep in mind that it’s always a good rule of thumb to talk to your doctor before incorporating vitamins and supplements into your diet.

What are the different vitamins and supplements


Supplements come in many shapes and sizes, with various mixes of vitamins and minerals inside.


Multivitamins are one of the most common forms of supplement. They typically have many - or all - of the essential vitamins, mixed into one convenient package. Some studies report that multivitamins can help with mood, memory (specifically on older adults), and immunity.

Joint health supplements

Joint health supplements are specially designed to promote joint health and minimize pain from arthritis. Oftentimes, these work by keeping the cartilage in the joints healthy.

Specific vitamin supplements

Most supplements are specific to one vitamin or mineral. Vitamin C supplements, for example, are ideal for those that are vitamin C deficient. These type of vitamins work best for those looking to fill a deficiency.

Who should use vitamins and supplements?

Vitamins and supplements are ideal for:

  • Those who are not meeting dietary requirements with food alone
  • Older adults, who likely need to supplement their consumption of B12, calcium, and vitamin D
  • Vegans and vegetarians who are missing key vitamins and minerals from meat (mainly B12, calcium, zinc, vitamin D, iron, and omega-3 fatty acids).
  • Those on low-calorie diets
  • Those with poor appetite
  • Those who are lactose-intolerant and need to supplement calcium intake

As a good rule of thumb, you should not make significant changes to your diet - like adding a vitamin or supplement - without first consulting your doctor.

Who shouldn’t use these?

Vitamins and supplements are likely not a good choice for:

  • Those who have not spoken to their doctor
  • Those who can get their nutrients from food
  • Those who do not have a vitamin deficiency
  • In some cases, those who are pregnant and breast-feeding (talk to your doctor about what’s best for you).

How do I use these?

Vitamins and supplements should be used:

  • In most cases, under doctor supervision
  • By precisely following the instructions on the label
  • Without exceeding daily recommended amounts
  • Either with or without food - check the label to know for sure
  • By those who are not also taking prescription drugs (talk to your doctor)

What does “IU” mean?

You may notice that many vitamins and supplements come with an “IU” measurement. “IU” is a term that stands for International Unit. It’s the unit of measurement for vitamins and some prescription drugs, and it can help you figure out how strong or weak each supplement is. In general 1 IU is roughly equivalent to .667 mg.

If you find IU confusing, it may be better just to measure by percent daily value.

What features exist?

Different amounts of each vitamin

Each supplement comes with a specific amount of each vitamin, so consider which vitamins it is that you’re looking for. If you just need a little extra vitamin C, go for the vitamin C supplement, not the multivitamin.

Need-specific options

Some supplements - like joint health supplements - are specially designed to address a specific need.


Most vitamins are unflavored, but some may have flavor.


Some vitamins are stronger than others. When deciding which vitamin is right for you, think about the daily required amount of that vitamin, the strength of the supplement, and how much of the vitamin you may already be getting from your diet. If you find strength values like “IU” and “mg” confusing, just focus on the percent daily value that specific vitamin is meeting.


Some supplements contain minerals like Calcium and Iron. These can help with bone or blood health, and your doctor may recommend specific minerals to look for.


Some of our supplements are gluten-free, making them a great choice for those with gluten intolerance.

Brittany's pro-tips

Keep in mind that many supplements are not strictly regulated by the U.S. Food and Drug Administration. That means that sometimes companies don’t put exact amounts on their supplements. While all our brands are well-recognized and secure, you’ll want to be careful shopping for supplements elsewhere. A good rule of thumb is to always talk to a qualified healthcare provider before taking vitamins and supplements.
