Important note: Supplements and herbs can interact with medications and may not be appropriate for everyone (including pregnancy, breastfeeding, or certain health histories). If you’re unsure where to start, a personalized consult is the safest, most efficient path.

1) Selenium (thyroid nutrient support)

Selenium is a trace mineral involved in antioxidant systems and thyroid-related enzymes. Many multivitamins include it, and standalone products often range widely in dose. If you’re considering selenium, it’s worth reviewing total intake from a multivitamin plus any “thyroid support blends.” NIH’s Office of Dietary Supplements outlines common supplement forms and typical dosing ranges found on the market. (ods.od.nih.gov)

2) Iodine (important, but easy to overdo)

Iodine is required to make thyroid hormones, and many people get it from iodized salt, seafood, dairy, and eggs. NIH provides age-based recommended daily amounts (adults: 150 mcg/day). (ods.od.nih.gov)

Where people run into trouble is stacking iodine sources (kelp capsules + thyroid blends + multivitamins). The American Thyroid Association cautions against routine iodine/kelp supplements providing more than 500 mcg/day and notes that too much iodine can contribute to thyroid dysfunction in susceptible individuals.

3) Ashwagandha (stress resilience—use thoughtfully)

Ashwagandha is often used in natural wellness circles as an “adaptogen” for stress support and sleep quality. NIH notes it may improve sleep and stress-related outcomes for some people, but also flags potential concerns: possible liver problems, possible effects on thyroid function, and unclear safety beyond about 3 months. (ods.od.nih.gov)

Practical tip: if you’re already using a thyroid product, a calming blend, or multiple capsules at night, this is one to review carefully with a clinician.

4) Black cohosh (menopause support—quality & safety matter)

Black cohosh has traditional use for menopause-related symptoms. A key consideration is product quality and safety. The National Center for Complementary and Integrative Health (NCCIH) notes that black cohosh is generally well tolerated in studies up to a year, but there have been rare reports of liver damage in people taking products labeled as black cohosh (and sometimes products may be contaminated or mislabeled). (nccih.nih.gov)

Step 1: Get clear on your goal (one goal at a time)

“Hormone support” can mean many things: cycle regularity, PMS comfort, perimenopause transitions, energy support, sleep, or stress resilience. Choose one primary goal for the next 6–8 weeks so you can actually assess what’s helping.

Step 2: Audit what you’re already taking

Make a simple list on your phone: multivitamin, protein powders, “thyroid support” blends, gummies, teas, sleep aids—everything. Many people discover they’re unknowingly doubling up on iodine or selenium because multiple products include them.

Step 3: Choose quality over quantity

If you’re investing in supplements, prioritize reputable manufacturing, transparent labeling, and a plan that keeps the total number of products manageable. If you’d like a reliable purchasing option, you can use our resource to purchase supplements from a source focused on quality and authenticity.

Step 4: Add one change, track, then reassess

Introduce one supplement or herb at a time and track a few markers (sleep, energy, cycle timing, digestion, mood). This is especially important with herbs that may affect thyroid function or interact with other products.

Keep it simple: one high-quality multivitamin (if appropriate) plus one targeted product is often easier to stick with than six separate bottles.

Plan around your mornings: if you always have coffee, pair supplements with a consistent habit (breakfast, brushing teeth, packing lunches) so you’re not relying on memory.

Choose safety-aware support: if you’re considering herbs like ashwagandha or black cohosh, prioritize guidance, product quality, and a clear stop/start plan.

Should I take iodine for thyroid support?

Many people already meet iodine needs through food (iodized salt, seafood, dairy, eggs). Adults typically need 150 mcg/day. If you’re considering iodine supplements, it’s important not to overdo it—ATA advises against routine supplements providing more than 500 mcg/day. (ods.od.nih.gov)

Can ashwagandha be part of hormone support?

It’s commonly used for stress resilience and sleep support. However, NIH notes possible liver problems and potential effects on thyroid function, and that safety beyond about 3 months isn’t clear. It’s best used thoughtfully and individualized. (ods.od.nih.gov)

Is black cohosh safe?

Black cohosh is generally well tolerated in studies up to a year, but there have been rare reports of liver injury in people taking products labeled as black cohosh. Product quality and appropriate guidance matter. (nccih.nih.gov)

What’s the biggest mistake people make with a supplements guide?

Taking multiple blends at once (thyroid + hormone + stress + sleep) without checking overlapping ingredients—especially iodine and selenium. A simpler plan, implemented consistently, is often easier to evaluate and maintain.

RDA (Recommended Dietary Allowance): The average daily intake level sufficient to meet nutrient needs for most healthy people in a specific age/sex group.

Adaptogen: A traditional term used for herbs that are thought to support the body’s stress response and resilience.

Kelp supplement: A seaweed-derived product that may contain high amounts of iodine; labeling and iodine content can vary widely. (thyroid.org)
