Supplementation dosage range

  • Beta carotene: 5 – 15mg per day

  • Alpha carotene: 500ug – 10mg per day

  • Lutein: 100ug – 5mg per day

  • Lycopene: 50ug – 15mg per day

  • Zeaxanthin: 100 – 500ug per day

 

Other information

It is generally accepted that natural forms of carotenoids from food perform better in the body than synthetic versions.

 

Cautions

  • No known toxicity for levels found in supplements.

  • The synthetic form of beta carotene should be avoided in heavy smokers.

  • Repeated intake of high doses of certain carotenoids, such as beta carotene, can cause a yellow/orange pigmentation of the skin. This is not a sign of toxicity and the pigmentation gradually subsides if supplementation is stopped or reduced to a sufficiently low level.

  • Extremely high intake of carrots can cause toxicity, but this is not due to the carrots’ beta carotene content.

  • Although certain carotenoids (e.g. beta carotene) convert into vitamin A in the body, they are not associated with the same risks/precautions/toxicity as preformed vitamin A (retinol and its derivatives), as conversion only takes place as the body needs it.

 

Factors which deplete levels, impair absorption and/or inhibit activity:

Fat blocking agents

Antacids

High doses of synthetic beta carotene (which blocks absorption of other carotenoids)

Alcohol
