ConsumerLab reports on vitamin A

Among 17 products, 4 failed to measure up.

That’s almost 25%.

Tests of vitamin A tablets and oils (including cod liver oil) showed that one supplement delivered nearly double its claimed amount of vitamin A. It’s of concern due to potential toxicity. Toxic effects of excess vitamin A include bone and liver abnormalities, as well as birth defects of the brain, eyes and head.

3 other products contained significantly less vitamin A than stated on the labels.

Here are the products tested.

  • Country Life
  • Ethical Nutrients
  • Futurebiotics
  • Garden of Life
  • Health from the Sea
  • Metagenics
  • Nature Made

  • Nature’s Way
  • Puritan’s Pride
  • Rite Aid
  • Solgar
  • Source Naturals
  • Spectrum Essentials
