  • Ingredient substitution recommendations when necessary

Labeling Phase

  • TSL logo added to approved products
  • Research driven language added

Research Findings

While these additives present a host of potential health complications, they add no nutritional value to the supplement beyond aesthetic appeal. Considering that these dyes have been linked to an increased risk of cancer, allergies, and hyperactivity in children, it seems fair to assume that most of us would prefer a vitamin without vibrant color if it meant a safer final product.[1,2]

Food Safety News

Synthetics added to vitamin products, typically to increase the vitamin's potency, but many synthetics are made from derivatives of coal tar - a known carcinogen found in cigarette smoke

Green Business Network

There is also some evidence that synthetic folic acid is more harmful than the natural folate in foods. It may build up in the body and raise the risk of cancer
