Reducol is GRAS (Generally Recognised As Safe) in the US for a variety of food groups and has DSHEA (1994 Dietary Supplement and Health Education Act, USA) allowance to make structure/function claims status when incorporated as an ingredient in dietary supplements. The FDA has issued an Interim Ruling for tall oil phytosterols esterified with vegetable oil fat to make health claims. Forbes has recently secured a similar ruling for the inclusion of a health claim for wood phytosterols in an un-esterified form ('free sterols').

Reducol has approval for use as margarine/vegetable oil spreads in Australia and New Zealand. Reducol may also be used in dietary supplements, under the "Dietary Supplements Act 1985" (NZ) and as a "listed" medicine on the ARTG (Australian register of therapeutic goods), with approval granted by the TGA (Therapeutic Goods Administration). Phytosterols have recently been cleared as safe by the FSANZ (Food Standards Australia and New Zealand) for use in milk drinks and cereal bars. Requests have also been made by local companies to add the ingredient to low fat yogurt and milk.

Forbes received an approval under the Novel Foods Regulations to market Reducol in milk-based drinks in November 2004. In February 2005, the Novel Foods Board of Finland determined that the use of Reducol in milk-based drinks was substantially equivalent to the use of Reducol in other food groups approved to contain phytosterols. These are: yellow fat spreads (margarine), fermented milk type products, soy drinks, low-fat cheese type products, yoghurt type products, spicy sauces and salad dressings. Marketing of these products with Reducol can now proceed in the European Union.
