Welcome to the forum

Everyone is an individual and dose required varies.

Do you have any recent blood test results and ranges you can add?

Generally we start on 50mcg Levothyroxine and dose is increased slowly in 25mcg steps until symptoms improve and TSH is around one and FT4 in top third of range

Bloods should be retested 6-8 weeks after each dose increase

For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested. Also extremely important to test vitamin D, folate, ferritin and B12

Low vitamin levels are extremely common, especially if Thyroid antibodies are raised

Do you know if you have high thyroid antibodies? Have you had vitamin levels tested?

Ask GP to test if not been done

Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and fasting. Last Levothyroxine dose should be 24 hours prior to test, (taking delayed dose immediately after blood draw). This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, best not mentioned to GP or phlebotomist)

Private tests are available. Thousands on here forced to do this as NHS often refuses to test FT3 or antibodies or all vitamins

Medichecks Thyroid plus ultra vitamin or Blue Horizon Thyroid plus eleven are the most popular choice. DIY finger prick test or option to pay extra for private blood draw. Both companies often have special offers, Medichecks usually have offers on Thursdays, Blue Horizon its more random

If antibodies are high this is Hashimoto's, (also known by medics here in UK more commonly as autoimmune thyroid disease).

About 90% of all hypothyroidism in Uk is due to Hashimoto's. Low vitamins are especially common with Hashimoto's. Food intolerances are very common too, especially gluten. So it's important to get TPO and TG thyroid antibodies tested at least once .

The initial recommended dose is:

For most people: 50–100 micrograms once daily, preferably taken at least 30 minutes before breakfast, caffeine-containing liquids (such as coffee or tea), or other drugs.

* This should be adjusted in increments of 25–50 micrograms every 3–4 weeks according to response. The usual maintenance dose is 100–200 micrograms once daily.

Levothyroxine is not a cure for hypothyroidism, if that's what you mean. It is thyroid hormone replacement, replacing the hormone your thyroid can no-longer make - or make enough of. You cannot live without thyroid hormone, so you have to replace it. And taking levo keeps you alive. So, I suppose you could say it helps, yes.
