Thiamin improves memory in hypothyroidism
Ameliorative effects of thiamin on learning behavior and memory dysfunction in a rat model of hypothyroidism: implication of oxidative stress and acetylcholinesterase.
Most Relevant Research
Our study focused on how thiamin, also known as Vitamin B1, can help with learning and memory issues caused by hypothyroidism. We designed an experiment using 50 rats, which we treated with propylthiouracil to induce hypothyroidism and then supplemented with varying doses of thiamin. Over a period of seven weeks, we assessed the rats’ abilities to remember and learn through standard tests like the Morris water maze and passive avoidance tasks.
We observed that thiamin significantly improved the ability of hypothyroid rats to recall the location of a hidden platform in the water maze. The rats that received higher doses of thiamin spent less time finding the platform and traveled shorter distances compared to those in the hypothyroid group who did not receive the supplement. Similarly, in the passive avoidance test, rats treated with thiamin demonstrated longer delays before entering a dark chamber, indicating improved memory retention.
Additionally, thiamin showed promise in reducing oxidative stress and decreasing acetylcholinesterase activity in the brain. This suggests that thiamin may help to rebalance certain chemicals in the brain, contributing to better memory function. Overall, our findings support the potential benefits of thiamin for addressing learning and memory deficits in cases of hypothyroidism, primarily by improving oxidative status and cholinergic function.

Improved energy levels
Most Useful Review
Vitamin B1 plays a vital role by converting carbohydrates into energy and aiding protein and fat digestion. It is essential for normal hydrochloric acid production in the stomach, crucial for processing proteins. I have autoimmune thyroiditis, often resulting in low gastric acidity. Thiamine helps maintain blood sugar and adrenal function, enhancing my energy levels. I take one small tablet in the morning with a meal and feel more energetic.

Improved cardiovascular function
Most Useful Review
The discovery of vitamin B1 (thiamine) is closely linked with beriberi disease, which causes mental disorders and muscle wasting, potentially leading to heart failure. Thiamine enhances brain function, memory, and appetite while supporting muscle tone and cardiovascular health. Allergic reactions can occur with injections, and certain substances can hinder vitamin B1 absorption. Combining B1 with other vitamins may heighten allergy risks, while vitamin C protects it from degradation. I prefer taking vitamins separately to avoid allergies, and after a week of taking B1, I feel positive effects.

Rash improvement noted
Most Useful Review
B1 or thiamine is a vitamin that needs to be consumed daily with food, which can be challenging. During my treatment for psoriasis, I was prescribed a course of injections containing thiamine. I decided to give these vitamins a try. The results have been notable, particularly on my hands, where the rashes have started to fade after six years of battling this condition. I also used a cream for better effect. Additionally, I ordered Omega3 supplements from a website, as I wondered if there might be a beneficial interaction. I hope my feedback is helpful to someone.
