Hi all, I got some blood tests recently. Here they are:
TSH 0.82 mU/l (0.30-4.50)
FT4 1.24 ng/dl (0.80-1.70)
FT3 3.14 ng/l (2.30-4.20)
Ferritin 108 (15-291)
Vitamin D 26 ng/ml (11-43)
Vitamin B12 318 ng/l (211-911)
Folic acid 9.32 (>5.38)
I realized my B12 is quite low, and my doctor agrees, so I have been getting B6-B9-B12 injections. I've had 4 so far, the first was about a month ago. Thank you so much SlowDragon for suggesting I test these! I am also getting some vitamin D supplements and trying to sunbathe when it's sunny.
Since I started the injections I've been having issues with tingling in my hands and feet. It started out with mild constant tingling in my feet and fingertips, and I thought it was getting better, but periodically I get it again and it spread to my arms as well. Sometimes it's more tingling and sometimes it's more painful.
I know it could be the nerves repairing after the B12 was replenished, but I got a bit worried when the tingling came back after days of feeling better. Has anyone experienced this? Is there anything else this could be related to? (maybe the injections are a coincidence??) Two days ago I got a gastroscopy and yesterday I was feeling understandably a bit low after the stress of the procedure, and low and behold tingling came back in force.

Igennus Super B is good quality and cheap vitamin B complex. Contains folate. Full dose is two tablets per day. Many/most people may only need one tablet per day. Certainly only start on one per day (or even half tablet per day for first couple of weeks)
Or Thorne Basic B is another option that contain folate
IMPORTANT......If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 7 days before ALL BLOOD TESTS , as biotin can falsely affect test results
Looking at previous posts....are you really only on 50mcg levothyroxine
That’s only a starter dose
Dose levothyroxine should be increased slowly upwards in 25mcg steps (or 12.5mcg if sensitive to dose change) Bloods retested 6-8 weeks after each dose increase
Levothyroxine doesn’t top up failing thyroid, it replaces it. So it’s important to get dose increased upwards as fast as tolerated.
Most people when adequately treated will need Ft4 and Ft3 at least 60% through range
Your results show you are still under medicated and ready for next dose increase in levothyroxine
You might increase by 12.5mcg initially (75mcg and 100mcg on alternate days)
guidelines on dose levothyroxine by weight
Even if we frequently don’t start on full replacement dose, most people need to increase levothyroxine dose slowly upwards in 25mcg steps (retesting 6-8 weeks after each increase) until eventually on, or near full replacement dose
Consider starting levothyroxine at a dosage of 1.6 micrograms per kilogram of body weight per day (rounded to the nearest 25 micrograms) for adults under 65 with primary hypothyroidism and no history of cardiovascular disease.
Traditionally we have tended to start patients on a low dose of levothyroxine and titrate it up over a period of months. RCT evidence suggests that for the majority of patients this is not necessary and may waste resources.
For patients aged >60y or with ischaemic heart disease, start levothyroxine at 25–50μg daily and titrate up every 3 to 6 weeks as tolerated.
For ALL other patients start at full replacement dose. For most this will equate to 1.6 μg/kg/day (approximately 100μg for a 60kg woman and 125μg for a 75kg man).
If you are starting treatment for subclinical hypothyroidism, this article advises starting at a dose close to the full treatment dose on the basis that it is difficult to assess symptom response unless a therapeutic dose has been trialled.
Taking more than 1,000 mg of supplemental B6 a day may cause nerve damage and pain or numbness in the hands or feet. Some of these side effects have even been documented after just 100–300 mg of B6 per day
Another bit of Google searching:
Potential Side Effects of Too Much Vitamin B6
Taking more than 1,000 mg of supplemental B6 a day may cause nerve damage and pain or numbness in the hands or feet. Some of these side effects have even been documented after just 100–300 mg of B6 per day
(I don't know why you are getting B6 injection in addition to B12. Find out how much
is in the shots. It's better to just get plain B12 or take it orally. If you don't have pernicious
I get pain in my hands and tingling in my feet when my T4 is low. 75mcg on Levo also puts my T4 levels at 1.2 and I feel awful. My T3 had to be at least 3.8 to function normally, however the only way I could get that was if my T4 levels were around 1.9.
