We now know that OTO-413 (BDNF) can improve hearing when injected into the cochlea. It's got me wondering if supplements that increase BDNF in the body can have any kind of noticeable effect.
I know there were people trying high doses of Turmeric / Curcumin, with some claiming it helped - though many others said they noticed nothing.
However, poking around online it looks like Coffee Fruit is a more potent supplement for increasing BDNF. Has anyone tried it?
I also wonder if stacking various BDNF supplements (Coffee Fruit Extract, Curcumin, Lutein, Fish Oil) could have an effect.
This is something I've been looking into for a while as my hyperacusis has become very debilitating and I need solutions.
My layman understanding is that for something like this to work, you really have to commit to it for a long time (3 months, perhaps). The problem we have is getting a high enough concentration to the cochlea. When taking BDNF systematically as opposed to a local injection, it has to be in your bloodstream for a very long time for it to eventually cross the blood-labyrinth barrier in notable quantities. Interestingly, there was a study that showed dark cocoa increased BDNF levels, but it took something like 12 weeks for it to become something noticeable/measurable in the body.
Not only this, but in addition to taking things that increase BDNF, you must also avoid substances/behaviours to decrease BDNF as well, otherwise it's kind of pointless increasing your BDNF with supplements for it to only be depleted. I would also add NT-3 and NGF as well for good measure, as a couple of studies have shown NT-3 is just as important if not more than BDNF. So, here's my list so far, which I'm thinking of starting and committing to from this week:
Foods/supplements that increase BDNF: Dark Cocoa (preferably 95-100%), Curcumin, Coffee Fruit Extract, Fish Oil, Quercetin, Resveratrol (although someone once posted Resveratrol can prevent neurogenesis so I don't know about this one??)
Behaviours that increase BDNF: High intensity exercise, good sleep routine, meditation and intermittent fasting (not 16 hours on 8 hours off but more like 48 hours minimum of full fasting)
Other supplements that help BDNF: Niacin, Magnesium.
Foods that decrease BDNF: sugars and carbs
Other things that decrease BDNF: bad sleep routine, stress, anxiety etc.
Supplements that increase NT-3: Astaxanthin and Lutein
Nerve Growth Factor: Lion's Mane
So if someone really wants to put this to the test, the above is what they need to commit to. A bunch of supplements, foods and good habits.
Just a note on Curcumin: I never see benefits when I take it in pill form, even with black pepper. So my advice is to find a raw/unprocessed powder and make your own paste (two teaspoons of turmeric with black pepper and oil. It tastes horrible but this is all we can do).
I really want to try this but it's quite difficult to commit to alone. If anyone wants to try something like this with me and exchange experiences I'm definitely up for it. Life is becoming excruciatingly painful.
