We value transparency at Best Nest Wellness.

We know an article was released about the purported lead content in various prenatal vitamins, including our prenatal vitamins, claiming that those vitamins contain lead in excess of FDA and Prop 65 limits. That article is wrong and misleading.


Best Nest prenatals are safe for pregnant mothers. Our prenatal vitamins contain far below even the strictest lead regulations. We want to bring you clarity and also some comfort. We know choosing a prenatal vitamin can be overwhelming and the last thing pregnant mothers need is misleading reports about what’s safe.


Here’s the data from our testing facilities:

The article didn’t include any actual testing data, but we’re confident to release the results of our testing. Best Nest vitamins are tested by two separate, independent labs before they’re cleared to be sold to the public.

  • The FDA’s 2018 safe lead consumption limit for vitamins is 12.5 mcg/day
  • The California Prop. 65 limit is 0.5 mcg/day.


Anything below those limits is considered safe by the FDA/California. Now compare those limits to Best Nest’s prenatals: 


  • Mama Bird Prenatal Multi+ contains 0.18 mcg/day
  • Mama Bird AM/PM Prenatal Multi+ contains 0.22 mcg/day





Mama Bird Prenatal Multi+

Micrograms = PPM x weight of the tablet x total serving per day

                  = 0.138 x 1.299 g x 1 serving per day (1 tablet)

                  = 0.18 mcg/day



Mama Bird AM/PM Prenatal Multi+

Micrograms = PPM x weight of the tablet x total serving per day

                  = 0.099 x 1.105 g x 2 tablets

                  = 0.22 mcg/day 



In other words, our prenatal vitamins contain less than 1/50th of the FDA allowable lead content, and less than half of the much stricter California Prop 65 standard.




Plants naturally contain small amounts of lead.

We make our vitamins from plants. It’s good to remember that any product with plant materials will contain some lead, because some lead is found in every plant.


Lead found in typical servings:

  • Fresh collard greens may contain up to 30 mcg of lead
  • Dry roasted mix nuts may contain up to 20 mcg of lead
  • Brussels sprouts may contain up to 15 mcg of lead
  • Sweet potatoes may contain up to 16 mcg of lead
  • Spinach may contain up to 15 mcg of lead


Compare those numbers to our prenatals, which contain much less.

We have a lot of questions and concerns about the “testing” reported in that article.

  • The article doesn’t provide or link to any actual test results of our prenatals. We can’t tell from the article what they think our results were, or what sort of testing was performed to reach that conclusion. We’re trying to get the actual results that the article relied upon.

  • According to the article, the reporters “partnered with Ellipse Analytics.” This is the same Ellipse Analytics whose “testing” was the basis for sensationalist articles in October 2017 about “widespread” chemical contaminants in baby food. Those claims were debunked and discredited when the actual testing results were released. You can read the full article here.

  • According to Snopes, Kevin Hicks, the CEO of Ellipse Analytics also came “under scrutiny for questionable practices when he was the CEO of BeverageGrades, [a] product labeling company” and filed a class action lawsuit alleging high arsenic levels in California wines. That Snopes article notes that, simultaneous with his class action, Mr. Hick’s company offered its services to certain retailers to help test and screen wine for potential contamination so the retailers could assure their consumers. Critics cited within the Snopes article called Mr. Hick’s actions “mere scare-mongering” that BeverageGrades was “using to drum up business.” That lawsuit was dismissed by the court.

  • We note the similarities here to the BeverageGrades situation. Here, Ellipse Analytics also operates a subsidiary website called Pure Market, that purports to rank vitamins by letter grade. But Pure Market’s website does not provide any substantive information about the tests conducted or the actual results, and so appears to assign grades arbitrarily based on “purity.” We suspect that the article is an attempt by Ellipse Analytics to drum up business for Pure Market, and we are concerned about the accuracy and motivation of Ellipse and Pure Market.

We make and take our own vitamins.
