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 daily sun exposure, I would suggest adding vitamin D to your formula.
Magnesium, iron, iodine and vitamin B12 all contribute to reducing tiredness and fatigue which you mentioned in your consultation. Vitamin B12 and iodine help to ensure your body can release enough energy. Iron ensures your body is adequately prepared to carry oxygen around your body and provide energy for your muscles. Magnesium is required for general brain health. Adding these 4 nutrients to your Vitbox Bespoke formula may help you to feel less tired during the day.
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.
Gut health is incredibly important to your overall health, from your immune system to your brain. Bloating/gas may be caused by poor digestion, improving your gut health may help with this. Consequently, I'd suggest adding our probiotic to your Vitbox Bespoke formula.
Magnesium and the omega 3 fatty acid, DHA, are vital for overall brain health, since you struggle with your focus, I'll make sure there's enough of these in your formula to help with this.
