What the research says about Thyroid Plus Women's ingredients
Educational summaries of published research on the individual ingredients in this formula, including honest evidence gaps where studies found mixed or null results - these are not claims about this finished product. CanPrev Thyroid Plus Women's own claims are the authorized uses under NPN 80118772: helping to support thyroid function in people with hypothyroidism, helping maintain healthy metabolism, and helping in energy metabolism in the body.
Iodine is the essential building block of thyroid hormone
A comprehensive 2026 review describes iodine as an essential micronutrient required for thyroid hormone synthesis and for metabolic, neurodevelopmental and immune function, noting that both deficiency and excess of iodine remain significant global public health challenges.
ReviewAn honest surprise: more iodine didn't clearly improve infant outcomes
A randomized-controlled trial that increased iodine intake via cod during pregnancy raised maternal urinary iodine but did not change maternal thyroid hormones, and infants in the higher-iodine group unexpectedly scored lower on one cognitive test - a result the authors flagged for follow-up study, not a confirmed benefit.
Human RCTInsufficient evidence to confirm a supplementation benefit in mild deficiency
A systematic review and meta-analysis of 37 publications concluded there is insufficient good-quality evidence to support current recommendations for iodine supplementation in pregnancy in areas of mild-to-moderate deficiency, though most trials did reduce maternal thyroglobulin and thyroid volume increases.
Systematic reviewSelenium enzymes convert T4 into the active T3 hormone
A review explains that selenium-dependent iodothyronine deiodinase enzymes catalyze the conversion of thyroxine (T4) into triiodothyronine (T3), and that selenium's antioxidant selenoproteins may help reduce inflammatory status in autoimmune thyroid conditions.
ReviewA real-food selenium source raised thyroid hormone levels in a pilot study
A pilot study in selenium-deficient hemodialysis patients found that one Brazil nut per day for three months significantly raised selenium levels, glutathione peroxidase activity, T3 and free T4 - though selenium supplementation was not able to fully restore T3 to normal levels in this population.
Human studySevere selenium deficiency measurably shifts a thyroid hormone biomarker
A study of patients with severe selenium deficiency found associated increases in free T4 that were reduced with selenium supplementation, supporting free T4 as a useful biomarker of selenium status when levels are severely low.
Human studyTyrosine can support cognition when neurotransmitters are temporarily depleted
A review of tyrosine research concludes it effectively enhances cognitive performance under short-term stressful or cognitively demanding conditions, mainly when neurotransmitter function is intact and dopamine or norepinephrine is temporarily depleted - not a general-purpose cognitive enhancer in every context.
ReviewTyrosine may help maintain cognitive function under environmental stress
A focused review of heat, hypoxia and cold stress concludes that tyrosine supplementation may help individuals maintain cognitive function in extreme environmental conditions, while noting more research is needed to clarify this and other proposed interventions.
ReviewAn honest complexity: amino acid effects were not straightforward
A randomized trial testing tyrosine/phenylalanine depletion alongside estrogen treatment in postmenopausal women found that cognitive changes after psychosocial stress were independent of the amino acid depletion itself - a reminder that tyrosine's real-world effects interact with other factors like hormones and stress.
Human RCTA documented case links zinc deficiency to reversible thyroid dysfunction
A case report describes a patient whose thyroid dysfunction, caused by selenium and zinc deficiency during long-term nutrition support, normalized after targeted zinc supplementation - illustrating zinc's role in thyroid hormone metabolism.
Case reportCopper is one of several trace minerals thyroid hormone synthesis depends on
A narrative review of nutrition and thyroid function names copper, alongside iodine, selenium, iron, zinc, magnesium, vitamin A and vitamin B12, as a micronutrient that influences thyroid hormone synthesis and regulation throughout life.
ReviewManganese supports the enzyme systems that guard cells from oxidative stress
A review of brain nutrition notes that manganese, alongside copper and zinc, participates in enzymatic mechanisms that protect against free radicals - a foundational antioxidant role for trace minerals in cellular health.
ReviewVitamin A supplementation lowered TSH in a controlled trial
A 4-month randomized, double-blind trial in premenopausal women found that vitamin A supplementation significantly reduced serum TSH and increased T3 in both obese and non-obese participants, suggesting a role for vitamin A in regulating thyroid-stimulating hormone.
Human RCTCombined with zinc and magnesium, vitamin A improved a thyroid hormone marker
A randomized, double-blind, placebo-controlled trial in hypothyroid patients found that 10 weeks of zinc, magnesium and vitamin A co-supplementation significantly increased serum free T4 and reduced inflammatory hs-CRP compared with placebo.
Human RCTRetinoic acid can modulate thyroid-specific gene expression in lab studies
A cell-line study found that all-trans retinoic acid, a vitamin A derivative, altered expression of thyroid-specific genes including the TSH receptor and thyroid peroxidase - early mechanistic evidence for vitamin A's influence on thyroid gland biology.
Preclinical studyA year of methylcobalamin improved nerve function markers in a controlled trial
A 1-year randomized, double-blind, placebo-controlled trial found that oral methylcobalamin (the B12 form used in this formula) significantly improved nerve conduction velocity, vibration perception, pain scores and quality of life compared with placebo in patients with low B12 and diabetic neuropathy.
Human RCTBoth a standard and a higher methylcobalamin dose improved symptoms similarly
A 16-week randomized trial comparing 1000 mcg and 2000 mcg daily oral methylcobalamin in patients with low B12 found both doses significantly improved neuropathic symptom scores, with the higher dose offering no additional symptom benefit beyond further raising blood B12 levels.
Human RCTAn honest caveat: some B12-related nerve evidence is still low-certainty
A Cochrane systematic review comparing acetyl-L-carnitine with methylcobalamin for diabetic nerve pain found only low-certainty evidence for functional improvement with either treatment, underscoring that not all B12-related nerve research has reached strong confidence levels yet.
Systematic reviewAshwagandha normalized thyroid hormone levels in a placebo-controlled trial
An 8-week, double-blind, randomized, placebo-controlled trial in subclinical hypothyroid patients found that ashwagandha root extract (600 mg/day) significantly improved serum TSH, T3 and T4 levels compared with placebo, with only mild, temporary side effects reported.
Human RCTAn honest caution: ashwagandha may raise thyroxine, warranting vigilance
A study measuring thyroid indices during an ashwagandha trial in bipolar disorder found that ashwagandha-treated participants showed thyroxine (T4) increases from baseline, echoing an earlier case report of ashwagandha-associated thyrotoxicosis - the authors advise vigilance for hyperthyroidism symptoms, especially at higher doses.
Human RCTAshwagandha root extract reduced stress, anxiety and cortisol
An 8-week, randomized, double-blind, placebo-controlled trial in adults with moderate stress and anxiety found that a proprietary ashwagandha root extract significantly reduced serum cortisol and improved Perceived Stress Scale and anxiety scores compared with placebo.
Human RCTHigh-dose Bacopa outperformed both low-dose Bacopa and Ginkgo for working memory
A network meta-analysis of 29 randomized trials (2,107 participants) found that high-dose Bacopa monnieri (600 mg/day or more) significantly improved working memory and short-term memory compared with low-dose Bacopa, Ginkgo biloba at either dose, and placebo.
Network meta-analysisA single Bacopa dose improved performance on demanding cognitive tasks
A double-blind, placebo-controlled crossover study found that a single 320 mg dose of a standardized Bacopa monnieri extract improved performance on a repeated, cognitively demanding test battery compared with placebo, in healthy adult volunteers.
Human RCTAn honest mixed result: not every cognitive measure improved
A 12-week randomized, double-blind trial combining Bacopa monnieri with cognitive training in healthy older adults found slower reaction time on one task in the Bacopa group despite favorable brain-imaging changes, underscoring that results vary by task and a larger study is needed to confirm mechanisms.
