Web MD is Not Your Friend
I have gone down a google rabbit-hole a time or two when it comes to symptoms I need an explanation for. I've convinced myself I have cancer more times than I'd like to admit. But since I've been trying to tame my crazy and actually research and learn more about my body and what it needs - I've found that vitamin deficiencies, more often than not, are the root cause of most of these symptoms.
The most prominent issue I've faced is exhaustion and pain in the nerves in my legs. The pain got so bad at one point that it hurt for me to pull my pants up because it felt like I had huge bruises on my thighs even though there were none there. My doctor ordered a full vitamin blood work panel and found out I was severely deficient in Vitamin B and Vitamin D, even though I was living in Florida at the time and was constantly in the sun and eating a healthy diet. Which just goes to show you really need to pay attention to your body and be sure to get regular testing - along with your diet and what you may need to supplement.

*I AM NOT A DOCTOR - have your vitamin levels tested and talk to your doctor before making any changes to your diet or taking supplements.
I'm due for a blood test and am curious to see where I can make improvements!
Loved reading this! I def need more vitamins 💛
Such a helpful post! I get headaches a lot so I will be more aware!!
Hi Mike! Spinach and Kale are both great sources of Vitamin K
This is so interesting! I’m definitely going to have to keep this in mind after a blood test. I normally take gummy vitamins because I never have enough iron.
