SVCT1 - intestinal vitamin C transporter.
| Genotype | Impact | What it means |
|---|---|---|
| CC (Normal) | Normal | Normal vitamin C transport - good plasma vitamin C from diet. Maintain daily fruit and vegetables. |
| CT (Carrier) | Low impact | Slightly reduced vitamin C transport - modestly lower plasma levels. Eat vitamin C-rich foods daily (peppers, citrus, kiwi, broccoli). |
| TT (Variant) | Moderate | Lower vitamin C transport - reduced plasma vitamin C even with normal intake. Prioritise vitamin C-rich foods through the day; a modest supplement may help. |
