Thyroid hormone production and metabolic support.
Dose & timing
- 125 mcg — daily
Why it’s in the stack
Required substrate for thyroid hormone synthesis — RDA is 150 mcg/day. Bryan's slightly lower 125 mcg from kelp leaves headroom for dietary iodine (sea salt, fish, dairy). Don't go above ~500 mcg without thyroid monitoring; both deficiency and excess cause goiter.
