Millions of Nigerians take daily vitamin and mineral supplements believing they are supporting their health. But independent laboratory analysis commissioned by The Consumer News suggests that a significant proportion of supplements sold in Lagos markets do not contain what their labels claim.
What we tested
We purchased 30 supplement products from markets and pharmacies across Lagos Island, Victoria Island, Surulere, Alaba, and Ikeja. Products included vitamin C, vitamin D, zinc, magnesium, and multivitamin formulations from brands ranging from internationally recognised names to locally produced products.
What the lab found
Eleven of the 30 products — 37% — contained less than 50% of the stated dose of their primary active ingredient. Four products were so under-dosed they were effectively inert. Two products contained substances not listed on the label, including one that contained traces of an antihistamine compound.
What you should do
Purchase supplements only from NAFDAC-registered pharmacies and always verify the NAFDAC registration number at nafdac.gov.ng/verify. If a supplement does not display a visible NAFDAC number, do not buy it.
