Saffron

Saffron is the dried red stigma of the crocus flower, Crocus sativus. Each flower gives three stigmas, and they are picked by hand. That is why saffron costs more per gram than any other spice, and why a genuine saffron supplement is never the cheapest capsule on the shelf. Three compounds carry the interest: crocin for the colour, safranal for the aroma and picrocrocin for the bitter taste. You will find the same plant in our wider range of herbal supplements.

Extract or ground stigmas

Two things separate one saffron capsule from another: the form and the standardisation. Ground stigmas are the whole spice in a capsule, usually in larger milligram amounts. A standardised extract is concentrated and measured, so each capsule gives the same amount of crocins and safranal. That matters, because the plant itself varies by harvest and origin. Most human studies use standardised extracts at roughly 28 to 30 mg a day, taken once daily. A label that says only saffron 100 mg tells you the weight, not the content.

On the label, we look for:

• the plant part: stigmas, not petals or flower powder
• a standardisation figure, such as the percentage of crocins and safranal
• the amount per capsule, so you can compare products fairly

The price of saffron makes it a target for adulteration. Cheaper material such as safflower, marigold petals or dyed plant fibres can pass for saffron in a powder. Laboratory testing is the only reliable way to catch this, which is why sourcing and paperwork matter more here than in most plant supplements.

How we choose saffron

We judge saffron on three things: the form, the dose and the combination. We prefer standardised extracts, because you can see what you get per capsule, and we stay close to the amounts used in research instead of numbers that only look impressive. A combination earns its place when the added nutrient does real work, for example vitamin B6 or magnesium, which carry approved claims for normal psychological function. Because saffron is easy to adulterate, we buy directly from the brands, our compliance team checks every product before it goes live, and independent labs spot-check batches. You can read how we select our brands.

Who saffron suits, and what to expect

Most people who buy saffron are looking for support with mood, calm or sleep, and often already use something for the same goal, such as magnesium in the evening. Saffron sits in the same corner of the routine: one capsule a day, at a fixed moment, usually with a meal.

We keep the expectation honest. There is no authorised health claim for saffron, so we do not promise a mood effect, and we describe products by their content rather than by results. Trials generally run four to eight weeks, so if you try saffron, give it at least three to four weeks of daily use before you decide. Saffron is not for everyone: if you take antidepressants or blood-thinning medicines, speak to your GP or pharmacist first, and skip it during pregnancy and breastfeeding.

Saffron also turns up inside sleep and mood blends, combined with magnesium, B vitamins or melatonin. If you prefer a single ingredient, choose a plain saffron capsule, so you know exactly what you are testing. The blends are grouped in our MIND + SLEEP collection.
