B. Magi: FDA found toxic yellow oleander and undeclared ingredients

FDA testing found toxic yellow oleander compounds and phenolphthalein in B. Magi. See the confirmed risks, evidence limits, and urgent steps for US buyers.

The FDA advises consumers not to purchase or use B. Magi, a product promoted for weight loss on websites including lamilagrosalab.com and possibly in some retail stores. FDA laboratory analysis confirmed three ingredients missing from the label: phenolphthalein, neriifolin, and thevetin B. Two are associated with toxic yellow oleander. This is a product-specific laboratory finding, not speculation based on advertising. [1]

What FDA found in B. Magi

The FDA says neriifolin and thevetin B occur in yellow oleander and can cause neurologic, gastrointestinal, and cardiovascular effects that may be severe or fatal. FDA’s safety alert lists B. Magi as a 30-capsule product sold by Suerte Y Salud LLC through lamilagrosalab.com; the agency says the firm had not responded to its calls or emails at the time of the alert. That statement describes FDA’s contact attempts, not what happened in any customer call. [1][2]

Why these findings matter

Phenolphthalein is also unlisted. FDA says studies suggest it may increase cancer risk. The National Toxicology Program classifies it as reasonably anticipated to be a human carcinogen based on animal studies, while noting that human cancer data are inadequate. This does not prove that a consumer will develop cancer from B. Magi; the amount and exposure are not given. The confirmed yellow-oleander compounds alone are a serious reason to avoid the product. [1][3]

What the record does and does not establish

FDA does not publish the tested lot, the amount of each substance, total sales, or a complete seller list. Its finding does not prove every package has an identical formula, establish what a particular seller knew, or show that B. Magi safely causes weight loss. We found no verified evidence in these notices for a phone upsell, expensive “course,” or named seller’s intent, so we do not make those claims. These translations report US FDA findings and do not establish sales or legal status elsewhere. [1][2]

What US buyers should do

  • If you have B. Magi, follow FDA advice: do not use it. Keep the bottle and label for identification. [1]
  • If you have taken it, contact a healthcare professional immediately—even if you stopped some time ago—and share the FDA notice. [2]
  • For serious symptoms in the United States, call 911 or contact a poison control center. FDA also accepts suspected reactions through MedWatch. [2]

Our assessment

We do not recommend B. Magi. FDA laboratory testing found three undeclared substances, including neriifolin and thevetin B associated with toxic yellow oleander; FDA warns these can cause severe or fatal effects and tells consumers not to purchase or use the product. The evidence does not establish a cancer outcome in a particular user, seller intent, or the contents of every package. The confirmed findings are already enough to make this a product to avoid.
