We value transparency at Best Nest Wellness.

Best Nest Wellness is very concerned by the allegations that our vitamins could somehow be dangerous, because our vitamins continually pass even the Prop 65 levels for lead and other contaminants.


Best Nest Wellness tests all of our multivitamins for contaminants and heavy metals. All of our products are meticulously created, tested multiple times, and held to strict cGMP standards for manufacturing, packaging, and labeling. We source the highest-quality non-GMO ingredients and handcraft each batch under strict standards for purity and freshness in certified facilities in the U.S.A. We have comprehensive third-party testing at both ingredient and finished product levels for product ingredients, purity, microbes, heavy metals, and more. All raw materials and finished products have written specifications that must be met before being released. This includes limits of quantification (LOQs) for heavy metal testing. Very few manufacturers do this much testing, but to us, it is important. What is on the label is what is in the bottle.


Best Nest prenatals are safe for pregnant mothers and their babies. 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 raw data from our testing facilities:

Best Nest Wellness vitamins have always conformed to FDA standards, and we strive to meet and exceed the highest standards set by other authorities, even when we are not bound by those standards. All our prenatals are produced in compliance with 21 CFR Part 111 and applicable parts of the Food Safety Modernization Act listed in 21 CFR Part 117. The FDA has set a provisional tolerable intake level of 25 µg/day for pregnant or lactating women. The California Prop. 65 standard is 0.5 µg/day. Anything below those limits is considered safe by both the FDA and California. Our prenatal multivitamins contain far below even the strictest lead regulations. We already fall far below the FDA’s 2018 safe lead consumption limit for vitamins.

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


Anything below those limits is considered safe by both the FDA and California. Now compare those limits to Best Nest’s prenatal multivitamins: 


  • Mama Bird Prenatal Multi+ contains 0.21 µg/day
  • Mama Bird AM/PM Prenatal Multi+ contains 0.22 µg/day


Our prenatal vitamins contain less than 1/50th of the FDA allowable lead content, and less than 1/2 of the much stricter California Prop 65 standard.



Plants naturally contain small amounts of lead.

It’s important to remember that we make our vitamins with plant-based ingredients. Any product with plant materials will contain some lead, because every plant contains lead that it absorbs from the natural minerals in its soil. It is vitally important that pregnant women eat fresh green vegetables as part of their daily diet, which means that they are consuming (based on typical servings) at least some amount of lead.

Lead found in typical servings:

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


Compare those numbers to our prenatal multivitamins, which contain much less.

There are other kinds of vitamins that have lower lead levels, such as gummy vitamins. But gummies are typically full of gelatin (an animal product), corn starch, and sugar. We take our responsibility to help and nurture pregnant women very seriously, and the benefits of avoiding all those fillers in place of nutritious plant material are, to us, a no brainer. So while our plant-based vitamins do contain miniscule amounts of lead, those amounts are a drop in the bucket compared to the lead naturally contained in healthy foods, and our vitamins have always been safe for pregnant women to consume alongside their diets. We’re creating the most optimal vitamins that we can.

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

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

  • 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.”

  • We note the similarities here to the BeverageGrades situation. Here, Ellipse Analytics also operates a subsidiary website called PureMarket, that purports to rank vitamins by letter grade. But PureMarket’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 PureMarket, and we are concerned about the accuracy and motivation of Ellipse Analytics and PureMarket.

  • Furthermore, Ellipse Analytics is associated with the Clean Label Project, an organization that claims to be acting in favor of label transparency but that has other motives. Clean Label Project is currently being sued due to its dubious practices, which include racketeering and corruption due its testing and product grading activities, that are completely intransparent and arbitrary.

We make and take our own vitamins.


All of our products are formulated by our founder, a doctor-mom and neurologist. She takes them, and so do her family and friends. We choose every ingredient because we believe it to truly be the best that Best Nest Wellness can find. Each formula is crafted to make sure those ingredients have a purpose and a benefit. We created this brand because we needed it and wanted it for ourselves. We share it because we believe our products will help your families, just like they help ours.
