So, I went down a massive ferritin wormhole today and ended up here. I have been thumbing through the discussion only to learn we don't have a lot of definitive guidance here!
I have been battling fatigue for about a year. Have been working on systematically eliminating various medications I thought could be causing it (beta blockers, migraine prevention meds, etc). TRT numbers are perfectly in range. I did a bunch of labs, including some iron studies. My TRT doc didn't say much, because everything was "normal", including HGB and HCT. But, I just looked back at them and my ferritin of 30 (very low end of "normal") caught my eye, thus leading me to the wormhole.
I literally have many of the classic symptoms of iron deficiency without anemia (fatigue, poor mood, restless leg - rarely, some pain, etc) and I really wonder if my ferritin is the issue.
So far, it seems like there is some consensus on a few things. I'd love for others to help me summarize what we know, what we think we know and what we don't know.
Off the top of my head:
I am trying to crystalize what we think we know about this issue. Please feel free to correct, add or subtract anything to this list.
- There are a few theories on why testosterone treatment lowers ferritin, but the connection is pretty clear and well recognized
- Quitting TRT will raise your ferritin
- Lowering your dose might raise your ferritin
- There is debate about whether the form of TRT matters (ie injecting vs. cream)
- Why would the form of TRT matter? Is the mechanism for dropping ferritin related to your levels, regardless of how you get there? Or, are sustained high levels more important than absolute numbers?
- @Systemlord feels strongly that Jatenzo won't drop your ferritin. Why is that? Periodic drops in levels versus sustained high levels? If this is true, shouldn't cream be ferritin friendly? Seems like some here have low ferritin on cream, too. I never checked ferritin while on Natesto, but I would venture to guess it was normal. That said, I think Natesto left my testosterone levels a bit low, which also leads to fatigue
- It's really hard to balance raising ferritin without raising Hct
- Taking vitamin C may or may not help raise ferritin
- What seems pretty consistent is that guys who check ferritin and notice it's low tend to feel shitty. Seems like some guys drop TRT doses, or entirely drop TRT, ferritin goes up and they actually feel better than when on TRT
- if I'm wrong, please chime in
Only gonna chime in on the whole raising ferritin while having to worry about hct/ hgb levels thing. The reason people struggle with that whole thing, is because they thing they have to worry about hct and hgb, when they don’t. Yes, hgb and hct will most likely go up, if ur consuming/ supplementing with more iron, to get ferritin levels up. Guys see this as a problem, when it’s just a normal process of the body, not a problem. Yes, if hct gets above say 55%, I would probably start actively trying to lower it, but most likely guys will be fine even with a 55-57% hct level. Just to err on the side of caution, however, I would recommend that guys start looking into lowering it a bit, if they do see their hct level get to around 55%, to above. But the first thing guys think of, in regards to lowering it, is to donate blood. When the first thing they should be doing is trying to figure out how to be better hydrated. A guy can lower their hct level multiple points, simply by being better hydrated. Being better hydrated can also lower hgb levels, as well as their RBC level.
My point is, that anytime guys get stuck in the loop of raising iron/ ferritin levels, then donating blood because their hct went up, thus lowering their ferritin/ iron levels, they’re simply doing it wrong. The way to do it is, increase ferritin/ iron levels, if that’s the goal, and don’t worry/ fear certain HCT levels as much/ decrease HCT levels via improving hydration status, over donating blood. It’s literally that simple
