Going through your consultation, I can see you eat a good amount of veg per day, but your fruit intake could do with a little top up. To help ensure you're not low on any micronutrients because of this, I would recommend vitamin A and C.
Additionally, you mentioned that you don't eat a lot of dairy. Dairy is a great source of calcium and iodine, and consequently, I would recommend these to ensure a healthy thyroid and bones.
As you don’t eat much fish, an omega 3 supplement could benefit you. Our vegan omega 3 comes from the same source that fish get it from, algae! DHA, an omega 3 fatty acid, is the main structural component in the brain, eyes and skin cells, and it is very important to include it in the diet, to help with these areas.
Vitamin D can be obtained through foods such as fish, but it is mostly acquired through synthesis when sunlight contacts the skin. The UK government recommends 15 minutes of sun exposure daily to get the right amount of vitamin D, but this can be quite hard due to the weather. As you can't manage to get much sun exposure, I would suggest adding vitamin D to your formula.
As you mention you live in a polluted area, I would recommend adding vitamin C to your formula. Vitamin C is a powerful antioxidant known to reduce the negative effects of breathing the air of a polluted city.
In your consultation, you mention that you suffer from low mood/anxiety. This may be due to low serotonin levels in your brain. 5-HTP, a naturally occurring amino acid, can help to increase the levels of serotonin, as your body uses 5-HTP to make it. Magnesium is very important for brain health and can help with mood. Therefore, I would recommend including both of these in your formula.
