Is Your Saffron Real? Standardization & Adulteration
Saffron is one of the most faked spices: a 2026 review put adulteration of the spice at about 20 to 30%. Buy a supplement that states its strength, such as Nootropics Depot Saffron Extract, which states at least 7.5% crocins, saffron’s main active compounds. Of the 8 we list, only Thorne is on a public testing list.

Cost is per 30 mg, the trial amount, at each brand’s own price (October 18, 2026); Amazon’s can differ. Nootropics Depot’s store now sells a different saffron, so it has no brand price. Standardization is what each label states.
What “standardized” means
Real saffron gets its color from crocins, its smell from safranal and its bitter taste from picrocrocin. A lab can measure all three, and the international grading standard (ISO 3632) uses them to grade saffron. A label that states one of them, such as “7.5% crocins” or “0.3% safranal,” tells you how strong the extract is. A label that says only “saffron extract 30 mg” does not.
How saffron is faked
A 2026 review estimated that 20 to 30% of saffron spice sold is adulterated. Common fakes are safflower, marigold and turmeric, and some are colored with synthetic dyes (Mehdizadeh 2026). The review is about the spice, but it is why a supplement’s stated strength matters.
How to check your bottle
- Look for a stated percent of crocins or safranal, or a named extract like affron.
- Check the milligrams: trials used about 30 mg a day. An 88.5 mg generic extract is not the same thing.
- Look for an outside testing mark, like NSF, and search the program’s list for the product name.
Questions people ask
Is saffron from a grocery store real?
Not always. Loose saffron spice is often faked (Mehdizadeh 2026). A supplement that states its standardization is easier to trust.
What does ISO 3632 mean?
It is the international grading standard for saffron spice. It sorts saffron into grades by its color, taste and smell compounds measured in a lab. Supplements rarely print it. A stated crocin or safranal level is the brand’s own claim about strength; no outside group checks it unless the product is on a testing list.
Who should ask a doctor first?
Ask your doctor before taking saffron if you are pregnant or breastfeeding, or take an antidepressant or other medicine. Do not take more than the label says.
