Is Your Chlorophyll Really Natural?
Let’s take a closer look at sodium copper chlorophyllin, the ingredient found in most liquid chlorophyll supplements.
While it’s marketed as “chlorophyll,” it’s actually a semi-synthetic compound. Natural chlorophyll is fat-soluble and magnesium-based. Sodium copper chlorophyllin is made by:
• Extracting chlorophyll from plants like alfalfa
• Replacing the magnesium with copper
• Altering the molecule to make it water-soluble and shelf-stable
This version is more convenient and widely used, but it’s not without concern.

Long-Term Use: What to Know
Although generally considered safe in small amounts, regular or long-term use of sodium copper chlorophyllin may lead to:
• Copper overload or imbalance, especially if you already get copper from food, water, or supplements
• Zinc depletion, since copper and zinc compete for absorption
• Unknown nutrient interactions, as its altered structure doesn’t behave like natural chlorophyll
• Liver stress, in rare cases with high or prolonged use
There is also limited research on how daily use over months or years may affect overall health.
⸻
Who Should Avoid or Limit Sodium Copper Chlorophyllin?
You should avoid or limit use if you have:
• Wilson’s Disease (a condition where the body stores too much copper)
• Copper sensitivity or toxicity
• Liver disorders, where copper accumulation could worsen the condition
• Mineral imbalances, particularly low zinc or iron
• A sensitive digestive system, as high doses may cause cramps, loose stools, or greenish discoloration in stool or urine
⸻
Medication Interactions to Watch For
If you’re taking any of the following medications, speak with your healthcare provider before using sodium copper chlorophyllin regularly:
• Penicillamine (used for Wilson’s disease and rheumatoid arthritis)
• Zinc supplements, since absorption may be impaired
• Iron supplements, as mineral interactions may occur
• Birth control pills, which can alter copper levels in the body
• Chelation therapies involving minerals or metals
• Any medications processed through the liver, especially those with narrow dosing ranges
⸻
Safer Alternatives
If you’re seeking a more natural source of chlorophyll, look for products that contain:
• Nettle leaf
• Wheatgrass
• Alfalfa
• Mulberry leaf
These retain more of the original structure and plant-based nutrients, including magnesium, without synthetic modifications.
