Are Kirkland Vitamins Good? (Quality, Reviews + More)

Are Kirkland vitamins Good

If you’re looking for a cheap vitamin supplement, you’ve probably come across the Costco brand “Kirkland” which you can even purchase on Amazon.

They are very good value compared to a lot of the other supplements that are available so you might be wondering, are Kirkland vitamins good?

Yes, Kirkland vitamins and mineral supplements are low in cost but good quality and they have been independently certified by the USP to prove that they contain all of the ingredients listed on the label. They are among the best value vitamins that are available on the market and deliver all of the goodness that they claim, though they do often use synthetic nutrient forms and may contain gelatin.

This article will go into detail about the quality of vitamins that you get from Kirkland, and whether they are as effective as other, more expensive brands.

Are Kirkland Vitamins as Good as Other Brands?

Kirkland vitamins may be cheap but, for the most part, they contain the same ingredients that you would find in any other supplement – and they do the job just as well.

The vast majority of the vitamin and mineral supplements that Kirkland offers have been independently certified by the USP (United States Pharmacopeia) to ensure that they offer all of the ingredients that they claim to, at a high standard.

Many Kirkland supplements do contain gelatin, which is not vegan-friendly, and they often use synthetic nutrients instead of those that are naturally occurring.

This is very common among supplements but may not suit your personal preference.

There are a lot of different combinations of vitamins and minerals available under the Kirkland brand, but the multivitamins contain good nutrient diversity and offer the quantities that you need.

They are also a reasonable size and easy to swallow, which is not always guaranteed when it comes to multivitamins.

What Should You Look for When Buying Vitamins?

Whenever you are buying supplements, you should be looking carefully at the label to ensure that the product suits your needs. You don’t want to be taking the wrong vitamins or missing out on something that is important for your health.

Something else to look out for on the label is a certification that indicates the trustworthiness of what is claimed on the packaging.

The USP Verified seal on Kirkland multivitamins is proof of purity, quality, and potency that has been evaluated by the FDA.

You also want the vitamins you are buying to be within their expiry date, so do be careful when you are shopping for deals online.

The expiry dates are a guarantee that the supplements are still fresh and potent, though they are unlikely to ever become harmful or dangerous.

Do I Need to Buy Vitamin Supplements?

There is a lot of persuasive marketing out there that seems to promise supplements as some kind of miracle cure or a solution to all of your problems, but what are vitamins and minerals actually for?

Vitamins and minerals, like calcium, iron, or vitamin D, are essential for keeping you healthy and making sure that your body is working properly.

Fortunately, they are generally only needed in small amounts and most people get all that they require from a balanced and healthy diet.

If you have a specific deficiency or are lacking some nutrition in your diet, then supplements can help to fulfill your body’s needs to keep you healthy and well.

A doctor may also recommend supplements under certain circumstances, such as when you are pregnant or trying for a baby, or if you are suffering from a medical condition.

Is it Safe to Take Supplements When You Don’t Need Them?

There are specific amounts of each vitamin and mineral that you should be getting every day and exceeding this can have side effects.

For the most part, it is generally safe enough to take a small quantity of supplements when you don’t need them, but taking too much or taking them for too long can be harmful to your body.

Your body can only use the vitamins and minerals that it needs, and many vitamins are water-soluble so the excess is flushed out of your system.

Scientists and doctors agree that there is no advantage to taking more than the recommended amounts but overdoing it can have consequences.

For example, too much zinc or vitamin C can lead to stomach cramps, diarrhea, and nausea, and excess selenium can cause hair loss and gastrointestinal problems.

Common nutrients that people take too much of include:

  • Vitamin D. Regularly exceeding the recommended amounts of vitamin D can cause heart problems.
  • Folic acid. While it is recommended during pregnancy, taking too much folic acid can hide signs of a potentially dangerous vitamin B12 deficiency.
  • Calcium. Unhealthy amounts of calcium in the bloodstream can cause constipation, kidney problems and heart issues.


The truth is that Kirkland vitamin and mineral supplements are as good as they say they are. They are verified for potency, quality, and purity, and are some of the cheapest on the market.

They may contain gelatin and synthetic nutrients, but you are unlikely to find a higher quality supplement for the price.
