Vitamin B9 (folate) is a water-soluble vitamin that plays a vital role in DNA synthesis and the formation of blood cells. It also supports tissue repair and is especially important during pregnancy to help prevent neural tube defects.

Without enough folate, red blood cells may not form properly, potentially leading to megaloblastic anaemia with fatigue and shortness of breath.
Essential for cell growth and tissue division, it supports periods of rapid development: pregnancy, childhood, and adolescence.
It contributes to the healthy formation of the neural tube in early pregnancy and supports brain function in adults, helping maintain cognitive and mood balance.
Spinach, kale, and Swiss chard can provide around 100 µg of folate per 90 g cooked portion (about 25% of RI).
Lentils, chickpeas, and kidney beans can provide up to 180 µg per cooked cup (about 45% of RI), plus fibre and plant protein.
Oranges and grapefruit provide around 40 µg per fruit (about 10% of RI) and also bring vitamin C, which supports iron absorption.
Half an avocado provides around 60 µg (about 15% of RI), along with heart-friendly monounsaturated fats.
Sunflower seeds and almonds contain folate, while some fortified cereals can cover 100% of RI in a single serving.
Beetroot provides about 109 µg/100 g (27% of RI), and chicken liver about 580 µg/100 g (145% of RI)—best enjoyed in moderation.
| Food | Folate (µg/serving) | % RI |
|---|---|---|
| Cooked spinach (90 g) | 100 | 25% |
| Cooked lentils (1 cup) | 180 | 45% |
| Medium orange | 40 | 10% |
| Half an avocado | 60 | 15% |
| Chicken liver (100 g) | 580 | 145% |
Adults often aim for 400 µg/day, and pregnancy typically 600 µg/day. Supplementation may be advised before and during pregnancy.
Megaloblastic anaemia can show up as fatigue, paleness, and shortness of breath.
Diarrhoea and bloating can sometimes appear when folate intake is low, as intestinal cell renewal is affected.
Difficulty concentrating, memory issues, or irritability may point to a slow-building deficiency.
Prioritise leafy greens, legumes, and citrus fruits regularly. For a refined addition to your routine, enjoy a cup of Organic Ceremonial Matcha, which can complement your day with plant nutrients and antioxidants.
