Lycopene Recommended Daily Intake: Current Evidence
Lack of Official Lycopene Recommended Daily Intake
There is currently no universally established recommended daily intake (RDI) for lycopene. This is due to variability in lycopene content across different foods, differences in measurement units, and inconsistent intake data from various populations and studies 127. The absence of an official RDI makes it difficult to compare intake levels internationally or to set clear dietary guidelines .
Proposed and Observed Lycopene Intake Levels
Several studies have attempted to estimate or propose daily intake levels that may provide health benefits:
- Some research suggests that consuming about 50 mg of lycopene per day could offer protective health effects, such as reducing the risk of cardiovascular diseases, osteoporosis, and certain cancers .
- Other studies recommend a lower intake, with 5 to 10 mg per day shown to significantly increase blood lycopene levels and reduce oxidative stress in healthy adults .
- A functional food modeling study recommends a daily intake of 17.85 mg of lycopene to achieve antioxidant benefits .
Average Lycopene Intake in Different Populations
Actual lycopene intake varies widely by country and population:
- In many countries, average daily intake ranges from 5 to 7 mg per day 27.
- In Canada, women consume an average of 6.14 mg per day, with high variability .
- In Korea, average intake is lower, around 1.9–2 mg per day .
- Some studies report higher average intakes, such as 12.6 mg per day among certain young adults, but only a minority of people reach this level 56.
- Another study found an average intake of 25.2 mg per day, with fresh tomatoes accounting for about half of total lycopene intake .
Food Sources and Dietary Patterns
The main dietary sources of lycopene are tomatoes and tomato-based products (such as ketchup, tomato juice, and tomato puree), as well as watermelon and pink/red grapefruit 1567+2 MORE. Processed tomato products often contain higher lycopene concentrations than fresh tomatoes . However, many people do not regularly consume enough lycopene-rich foods to meet proposed beneficial intake levels 2568.
Safety and Regulatory Guidelines
For lycopene used as a food additive (E 160d), the European Food Safety Authority (EFSA) has set an acceptable daily intake (ADI) of 0.5 mg per kilogram of body weight per day. For a 70 kg adult, this equals 35 mg per day . Exceeding this level through food additives is not recommended, but typical dietary intake from natural sources is usually well below this threshold .
Conclusion
While there is no official recommended daily intake for lycopene, research suggests that consuming between 5 and 50 mg per day may provide health benefits, with 17–18 mg per day often cited as a practical target for antioxidant effects. Most people consume less than this amount, highlighting the importance of including more lycopene-rich foods, such as tomatoes and tomato products, in the diet. Safety guidelines for lycopene as a food additive are higher than typical dietary intakes, indicating that increasing lycopene intake through natural foods is generally considered safe.
