Folic Acid Improves Cognitive FunctionFolic acid attenuated learning and memory impairment via inhibition of oxidative damage and acetylcholinesterase activity in hypothyroid rats.
We explored how folic acid (FA) affects cognitive decline linked to hypothyroidism in a rat model. Over seven weeks, rats received PTU to induce hypothyroidism and were given varying doses of FA.
The results were promising, showing that FA improved memory and learning in tested tasks. The higher the FA dose, the better the outcomes, with reduced cognitive decline and changes in brain enzyme activity.
This suggests that folic acid may offer protective benefits against cognitive issues related to hypothyroidism, primarily by managing oxidative stress.

Folic acid improves cardiac structureLight and ultrastructural study in the propylthiouracil-induced hypothyroid rat heart ventricles and the ameliorating role of folic acid.
We explored the impact of folic acid on heart changes in rats with hypothyroidism. The study included five groups of male albino rats, with some receiving folic acid while others did not. We found that hypothyroidism caused clear structural heart issues. However, folic acid seemed to help improve muscle fiber arrangement and overall heart architecture, especially when given as a post-treatment after restoring normal thyroid function. While folic acid showed promise, more research is needed to fully understand its benefits in humans.

Folic acid shows potential benefitsFolic acid alleviates oxidative stress and hyperhomocysteinemia involved in testicular dysfunction of hypothyroid rats.
We evaluated how folic acid impacts testicular function in hypothyroid rats. In this study, we observed that hypothyroidism led to significant disruptions in biochemical markers and sperm production.
Importantly, folic acid seemed to enhance spermatogenesis more effectively when administered after normal thyroid hormone levels were restored, suggesting a promising role for folic acid in supporting testicular health.
While our findings are promising, confirming these results in humans could pave the way for using folic acid as a complementary treatment alongside traditional therapies for hypothyroidism.

Folic acid reduces homocysteine levelsThe impact of B vitamins on the functioning of methylation cycle in the liver and the kidneys of hyper- and hypothyroid rats.
We examined how B vitamins—especially folic acid—affect homocysteine levels in hypothyroid rats. By modeling thyroid dysfunction, we noticed that hypothyroidism led to reduced enzyme activity that helps process homocysteine, raising its levels in the blood.
Remarkably, when we administered folic acid along with other B vitamins, we observed a significant drop in those homocysteine levels. This suggests that these vitamins may play a vital role in preventing endothelial dysfunction associated with hypothyroidism. However, we should remember this study was performed in rats, and further research is needed in humans.

Folic acid boosts hypothyroidism treatmentEffects of folic acid plus levothyroxine on serum homocysteine level in hypothyroidism.
In our double-blinded clinical trial, we evaluated how folic acid affects serum homocysteine levels in patients with hypothyroidism when taken alongside levothyroxine.
We followed sixty participants for two months, dividing them into two groups—one receiving just levothyroxine, and the other, levothyroxine plus folic acid.
Results were promising; while both treatments lowered homocysteine levels, the group taking folic acid experienced a more significant drop. This suggests that combining folic acid with levothyroxine could enhance treatment outcomes for hypothyroidism.
