Supplementing works (sometimes)

In mid-August, I found out that I was low in iron and B12. Specifically:

• Ferritin - 21 ng/mL (38 ng/mL - 380 ng/mL reference range)

• B12 - 197 pg/mL (200 pg/mL - 1100 pg/mL).

I started supplementing soon after with a daily 1000 mcg B12 (as cyanocobalamin) and 65 mg Iron (from 325mg Ferrous sulfate).

Just 32 days later, I followed up and was surprised to see that both my deficiencies had seemingly been resolved, with the following levels:

• Ferritin - 62 ng/ml

• B12 - 677 pg/mL

This might not seem that crazy, but it's nice to see that the supposedly unregulated supplements that flood the market at cheap prices can actually work as intended!
