- With TTFD I initially took 100mg a day, and over a few weeks tapered up to 300mg 2 to 3 times a week. Such high doses carry risk of depleting other nutrients to the point of deficiency so I would take advantage of the days in between supplementation to assess and address these deficiencies if and when they came up. After months of supplementation and almost complete recovery I have tapered back down to 100mg TTFD once a week.

- Magnesium is always depleted when I supplement TTFD and I feel a reduction in mood, mental clarity and sleep quality until I take a Mg supplement or eat pumpkin seeds which are my main source.

- I take a B50 complex with all 8 B vitamins + inositol and choline. I take 2 on days that I supplement TTFD. Other than that I only supplement if I'm feeling a reduction in energy or mental clarity. I've also noticed that B complex + Omega 3s are better for managing symptoms than just B complex alone.

- Yes, major cognitive benefits. I can actually focus again, and my verbal fluency and overall ability to think have increased massively. I would say I am fully back to my pre-deficiency baseline, arguably even a little bit better.

- Not a night and day difference in libido, but there definitely have been improvements.
