Elemental Magnesium Label Claims Challenged

Takeaway -

Net impression is important

WLW# 249

If I list “Magnesium Glycinate Gummies 200 mg per serving,” does a reasonable consumer think there is 200mg of elemental magnesium in each serving? This recent NAD case is a good lesson in net impression, which is how consumers view advertising.

In this National Advertising Division (NAD) challenge case, the front-of-pack magnesium claim was cited as being possibly misleading since the product actually contains only 22mg of elemental magnesium.

From NAD case. “ the front label as “Magnesium Glycinate Gummies 200 mg Per Serving.” The Supplement Facts label on the back, however, states that the product contains only 22 mg of magnesium, or 5% Daily Value.”

This is a common practice, but what makes this case interesting is that secondary claims were also cited. This is likely what ‘tipped the scale’ that led NAD to find the “200mg” claim misleading. This shows that all marketing should be reviewed holistically through a consumer lens, and it highlights the importance of training all staff, including social media managers, in the nuances of compliance.

From NAD case. “… has displayed the front label (without the Supplement Facts label) on social media, as well as stated that its gummies have “200 mg of Magnesium per serving” without reference to “glycinate.”

What do you think? Do consumers think that a “Magnesium Glycinate Gummies 200 mg per serving” label claim means the product has 200mg of elemental magnesium?
