My test results are the EXACT same as yours for ferritin. My regular pcp said 26 was fine, but the dermatologist says he recommends to supplement if your ferritin is below 50. Probably doesn't help much, just seems like everyone has differing opinions.
Increasing your iron store (ferritin) would be a good idea as though in range it is low.
Using a good brand of iron supplement will boost this and about 50 will give you the
Level needed for a woman.
Try and increase with diet also, red meat green veg. Etc and vitamin C helps absorption. Drinking tea (tannin) inhibits iron absorption so don't drink tea at the same time
