Safety first. Supplements can cause side effects and interact with medicines. Read mushroom safety and interactions before you use any mushroom product.

Overview

Fortified foods have nutrients added that were not naturally in the food, or added back after processing. Examples include cereals, plant milks and spreads with plant sterols. A fortified food is not a supplement and is not the same as a food naturally rich in the nutrient.

What fortification is, in U.S. policy

FDA's fortification policy (21 CFR 104.20) is a voluntary framework for adding nutrients to conventional foods. It permits additions to correct a dietary insufficiency, restore nutrients lost in processing, balance vitamins, minerals and protein against calories, or keep a replacement food from being nutritionally inferior. It does not apply to dietary supplements, and FDA considers fresh produce, meat, poultry, fish, sugars and snack foods inappropriate for fortification. [1]

Plant sterol and stanol foods: the clearest example

Plant sterols and stanols are added to some spreads and drinks. A meta-analysis of 124 studies found that intakes of 0.6 to 3.3 g a day gradually reduced LDL cholesterol on average 6% to 12%, with the effect increasing up to about 3 g a day. [2] The FDA claim lists 1.3 g or more a day of plant sterol esters (or 3.4 g of stanol esters), consumed in two servings at different times of day, as part of a diet low in saturated fat and cholesterol. [3] Another meta-analysis compared plant sterols and stanols with policosanol. [4]

Where we could not find proper evidence

Proper evidence was not found in the sources we read for the health effects of fortified milk, fortified cereals or fortified plant milks as foods. We do not rank fortified foods against supplements: see Fortified foods vs supplements.

Safety and individual considerations

Adding fortified foods and supplements together can raise intake of some nutrients above need; a pharmacist or clinician can review your total. See Quality and labels. [5]
Plant sterol products are not designed for children or for people who do not need cholesterol lowering; ask a clinician. We did not find a source to quote on groups to avoid, so we make no claim beyond that.

Frequently asked questions

Is a fortified food better than a supplement?

We did not find a source comparing them. They are different products with different labeling rules. [1]
