Is liquid chlorophyll safe? Side effects & dosage

The common, harmless effects

• Green stool (or tongue). The most common effect, completely harmless — it's just the pigment passing through.
• Mild digestive upset. Some people get a little nausea or looser stools, especially at higher amounts. Starting small usually settles it.
• Sun sensitivity. Rare, and reported more with high doses — sensible sun habits cover it.

How much to take

Stick to the directions on your bottle — typically a teaspoon or capful in a glass of water, once or twice a day. More is not better; the label amount is plenty. If a big dose upsets your stomach, drop back to a smaller one.

Who should be cautious

If you are pregnant or breastfeeding, there isn't enough research to give the green light, so the honest answer is to ask your doctor or midwife first. The same goes if you take regular medication or have a health condition — a quick check with your GP or pharmacist is the sensible move before adding anything new.

The takeaway

Liquid chlorophyll has a reassuring safety record for healthy adults at normal amounts. The green surprise in the toilet bowl is the worst most people will encounter. Take it as directed, and get individual advice if you're pregnant, breastfeeding or on medication.
