 2. Spring Valley Reviews  

Spring Valley vitamins are the store brand sold exclusively at Walmart — although they're frequently confused with a small Missouri herb store of the same name. Spring Valley vitamins are affordable and widely available, but have also attracted enormous controversy in recent years. The types are as follows:

  • Vitamins 

  • Immunity 

  • Beauty & collagen 

  • Bone & joint 

  • Sleep & stress relief 

  • Cognitive 

  • Heart health 

  • Kids’ vitamins



In a study published in an October 2013 issue of BMC Medicine, researchers from the University of Guelph, Ontario, used DNA barcoding to evaluate the authenticity of 44 different herbal products from 12 supplement companies.

The study findings were shocking: 59 percent of the products tested contained DNA from plant species not listed on the label, and 30 out of the 44 products had no trace of the labeled main ingredient, but contained other products not listed on the label.

Of the 12 supplement companies whose products were involved in the test, only two of them had products with no substitution, contamination or fillers. Although the researchers didn't name the supplement companies, Forbes reported that Walmart's Spring Valley vitamins were included among the negative results, and printed a reaction from Walmart that confirmed this.

Aside from the simple and reasonable expectation of getting what you pay for is the fact that researchers in the aforementioned study noted that some of the contaminants they found pose serious health risks to consumers because of interactions with medications, allergies and contamination from ingredients that can cause harmful side effects with prolonged use.

Hundreds of different Spring Valley supplements remain available in Walmart stores and online, but have been stripped of "third-party verified" labeling that was deemed potentially misleading.

Olly is a supplement company based in San Francisco. It was founded by entrepreneurs Eric Ryan and Brad Harrington in 2013 and acquired by Unilever in 2019.

Olly specializes in gummy vitamins that are third-party tested. While some Olly products may offer benefits for certain health concerns, the gummies are not suitable for everyone, including those following a vegan diet. Known for colorful packaging and fruity gummy flavors, Olly supplements have become increasingly popular among health enthusiasts in recent years.

The company offers an assortment of gummies and capsules designed to boost mood, metabolism, gut health, hair growth, immune function, and more. Currently, Olly offers more than 60 unique formulations for children and adults. Products are grouped into the following categories on the brand’s website:

  • Ultra Softgels + Capsules

  • Wellness Boosts

  • Multivitamins

  • Kids

Olly partners with both domestic and international facilities to produce its line of supplements, and all products are manufactured in facilities that comply with the Current Good Manufacturing Practices (CGMPs) established by the Food and Drug Administration (FDA).

According to the company’s website, all supplements are also third-party tested in the United States, though the specific testing lab or facility is not disclosed.

Furthermore, many products are certified by NSF International, an independent organization that tests supplements to ensure safety and quality.

While Olly does not test any products on animals, not all Olly products are vegan-friendly.

In fact, most of the gummies are made with gelatin, which means they’re unsuitable for people following a vegan or vegetarian diet.
