Vitamin A

Form used in ThyroLove

Beta-carotene (750 mcg)

Why it’s in ThyroLove

Vitamin A plays a foundational role in thyroid function, immune balance, and even nutrient absorption, but not everyone needs or tolerates preformed vitamin A (retinol), which is why we use beta-carotene, a plant-based precursor that your body can convert as needed. This form gives your body flexibility so then it only converts what it needs, when it needs it. Plus, beta-carotene is a powerful antioxidant, helping to protect the thyroid and support overall immune resilience, which is especially important in Hashimoto’s.

The Science

• Vitamin A is critical for thyroid hormone metabolism, including the conversion of T4 to T3 in the liver and the ability of cells to uptake thyroid hormone. Study: PMC9592814

• It also plays a structural role in maintaining thyroid gland health, and deficiency may impair the gland’s function and its ability to produce hormones. Study: PMC10250628

• Vitamin A supports regulatory T cells (Tregs), which are key in helping calm autoimmune activity and prevent the immune system from attacking healthy tissues.
  

• There’s also a connection between certain SNPs (genetic variations) in vitamin A metabolism and a higher risk for Hashimoto’s, meaning some people may have an even greater need for consistent, usable vitamin A.
