Investigational / off-label — no FDA-approved dose exists. Trials studied oral enclomiphene citrate at 6.25-25 mg once daily (12.5 mg and 25 mg were the Phase-3 doses). Compounded enclomiphene is used off-label under a clinician at similar doses, but quality and content are not regulated.

Oral enclomiphene citrate raises testosterone and preserves sperm counts in obese hypogonadal men, unlike topical testosterone: restoration instead of replacement.
BJU Int (2016) · Rct
Two parallel randomized, double-blind, double-dummy, placebo-controlled, multicentre Phase-3 trials (ZA-304/ZA-305) of 12.5 mg and 25 mg enclomiphene vs testosterone gel (AndroGel 1.62%) in overweight men 18-60 with secondary hypogonadism

Maternal Iodine Status and Birth Outcomes: A Systematic Literature Review and Meta-Analysis
Nutrients (2023) · Meta analysis · n=42269
Birth weight was similar between UIC ≥ 150 μg/L and <150 μg/L (difference = 30 g, 95% CI −22 to 83, p = 0.3, n = 13, I2 = 89%) with no evidence of linear trend (4 g per 50 μg/L, −3 to 10, p = 0.2, n = 12, I2 = 80%).
Iodine fortification of foods and condiments, other than salt, for preventing iodine deficiency disorders
The Cochrane database of systematic reviews (2019) · Meta analysis · n=4317
This is equivalent to an increase of 38.32 µg/L (95% CI 24.03 to 52.61 µg/L).
Systematic review and meta-analysis of iodine nutrition in modern vegan and vegetarian diets
The British journal of nutrition (2023) · Meta analysis · n=4421
Vegan diets had the poorest iodine intake (17·3 µg/d) and were strongly associated with lower iodine intake (P = < 0·001) compared with omnivorous diets.
Based on meta-analyses showing urinary iodine concentration increases with supplementation. Effects only meaningful in iodine-deficient populations. Excessive intake (>300mcg) may increase thyroid cancer risk. Most studies used potassium iodide; kelp-derived forms have variable bioavailability.
AI-estimated from published studies. Interpret as directional guidance.
Iodine has a higher evidence score (8.5/10 vs 4.2/10) and wins in 3 of 3 categories.
For testosterone & cortisol balance, Iodine has a higher relevance score (85 vs 62).
