Pure Encapsulations Pure Encapsulations - Thyroid Support Complex, 60 caps
Pure Encapsulations Thyroid Support Complex - A comprehensive formula containing vitamins, minerals and herbal extracts. It was specifically designed to support healthy thyroid gland function. Iodine is absorbed by the thyroid gland and supports the formation of triiodothyronine (T3) and thyroxine (T4) hormones. l-Tyrosine is also a key component in the synthesis of thyroid hormones. Healthy selenium levels have been associated with maintaining healthy thyroid cell metabolism, as well as thyroid hormone function. Doubling as a powerful antioxidant, selenium combines with vitamin C and curcuminoids to neutralize free radicals, including those that affect iodothyronine 5'-monodeiodinase enzyme activity, the limiting factor in the conversion of T4 to the more active T3 hormone. Thyroid Support Complex also contains standardized extracts from forskohlii, guggul and ashwagandha, herbs with an extensive history of traditional use.

Why people keep reordering it
- Highly absorbable forms
- Chelated forms your body takes up, instead of oxide that mostly passes through.
- Calm and recovery
- Supports muscle relaxation, sleep quality and everyday stress resilience.
- Gentle on digestion
- Formulated to skip the laxative effect of cheaper magnesium.
Best suited to: eats little seafood, dairy or iodised salt, wants selenium at the dose used in thyroid research, would rather buy one bottle than five.
What the research supports
Two capsules give 150 mcg of iodine and 200 mcg of selenium, the core of a wider herbal blend. The bottle is a month's supply.
Selenium and thyroid trials use around 200 mcg of selenomethionine a day.
- Thyroid hormone (evidence: strong, from randomized controlled trial, observational)
- Iodine is a direct building block for both thyroid hormones. 150 mcg is the full adult requirement, which this delivers in two capsules.
- Thyroid enzymes (evidence: moderate, from randomized controlled trial)
- Selenium activates the enzymes that convert thyroid hormone into its active form. Trials around 200 mcg a day show real but inconsistent effects across different groups.
- Stress (evidence: moderate, from randomized controlled trial)
- Ashwagandha extracts lower cortisol responses to daily stress over several weeks of use. This bottle's 400 mg dose sits under the amounts most stress trials used.
- Hormone precursors (evidence: limited, from )
- L-tyrosine is the amino acid thyroid hormone is built from. In someone already eating enough protein, extra tyrosine adds little beyond what the diet already supplies.

Is it right for you
Worth it if
- Eats little seafood, dairy or iodised salt
- 150 mcg of iodine covers a full adult day of the one mineral thyroid hormone cannot be built without.
- Wants selenium at the dose used in thyroid research
- 200 mcg of selenomethionine is the trial amount, not the 25 to 55 mcg a general multivitamin carries.
- Would rather buy one bottle than five
- Iodine, selenium, zinc, tyrosine and four standardised herb extracts are already combined at set ratios, which is awkward and expensive to assemble yourself.
Look elsewhere if
- Anyone whose thyroid a practitioner already monitors
- Raise it with them before starting. Iodine at this level can move your numbers in either direction, and a formula with eleven actives makes it impossible to tell which one did what. A single-ingredient selenium is far easier to account for.
- Already takes selenium or eats Brazil nuts daily
- Two capsules put you at 200 mcg before anything else, against an adult upper limit of 400 mcg. Pick one source, or look for an iodine and tyrosine product with no selenium in it.
- Wants ashwagandha for stress
- A standalone ashwagandha extract standardised to 5 percent withanolides at 300 to 600 mg gives several times the withanolide content of the 400 mg in here.
What to expect
Nothing dramatic and nothing quick. Iodine and selenium act at the level of hormone production, which changes on a scale of weeks and shows up in bloodwork before it shows up in how you feel. Give it eight to twelve weeks, and get tested rather than guessing.
How it compares
- Compared with separate iodine and selenium capsules
- You also get 500 mg of tyrosine, 20 mg of zinc, vitamin A and four standardised herb extracts, at ratios already worked out for you. The tradeoff: You lose the ability to change one thing at a time. If something disagrees with you there are eleven suspects, and you cannot drop the iodine without dropping the selenium with it.
- Compared with a general multivitamin
- A multi rarely carries more than 55 mcg of selenium, almost never includes L-tyrosine, and will not have guggul or forskohlii in it at all. The tradeoff: This does not replace a multivitamin. The vitamin D is 200 IU across two capsules and there are no B vitamins, magnesium or iron.
