What it does
Supports vision, immune function and tissue development.
Possible deficiency symptoms
Deficiency can cause night blindness and eye-surface damage.
How supplementation is approached
Distinguish preformed vitamin A from beta-carotene and review existing multivitamin, liver/cod-liver-oil and eye-health products. Dr. Purser’s BCO1 teaching explains why conversion can be part of the discussion, but a gene result alone does not choose the form or amount.
Food sources
Eggs; dairy; liver; orange and dark-green vegetables containing provitamin A carotenoids.
Supplement forms
Retinyl palmitate, retinyl acetate and beta-carotene.
What to track and reassess
Review visual symptoms, actual nutritional findings and pregnancy plans before preformed vitamin A. Avoid accumulating several retinol-containing products.
From starting support to follow-up
If you and your clinician start a CMA replenishment plan, you may add one new product at a time, often waiting 3–7 days to see how you feel. A check-in is usually planned near ten weeks during an approximately 100-day period. Follow your written plan for amounts and timing. At follow-up, you may continue, change, or stop each item. This timetable does not automatically end longer-term support.
