- 0:00What do you do if you have an high SHBG?
- 0:03So for those of you who don't know,
- 0:04SHBG is a binding globulin that attaches to the hormones in your body
- 0:09and blocks them from being active or blocks them from your body being able to use them.
- 0:14So if you're somebody with a high SHBG,
- 0:17you could have all the hormones in the world,
- 0:20but your body's not able to actually utilize them because they're being blocked.
- 0:24So there are a few things that we know of for sure
- 0:29that can cause a high SHBG.
- 0:31So that would be things like oral contraceptives,
- 0:35too high of...
- 0:37So if you're using a large dose of thyroid,
- 0:41any sort of thyroid medication,
- 0:43prolonged fasting or long-term caloric restriction,
- 0:48and I've heard some experts say that if you're on a very carb-restricted diet,
- 0:52those are all things.
- 0:53Stress, I think, is another one.
- 0:55So those are the ones that I'm aware of anyway that can raise your SHBG.
- 0:58So obviously, you would want to take a look at those situations
- 1:02and see if you could alter your lifestyle or whatever
- 1:07to try to get those numbers lowered.
- 1:10I do know there are many people who are doing everything right to lower their SHBG
- 1:16and they still can't get it lowered.
- 1:17So for some people, it's kind of out of your hands.
- 1:21And in those cases, a lot of times people,
- 1:24your doctor would have to kind of dose your hormones even higher
- 1:30so to kind of make up for the high SHBG.
- 1:33I've heard conflicting reviews, but some experts say that taking the supplement
- 1:37boron may help lower, but I'm not for sure on the real,
- 1:42like the accuracy of if that helps or not.
- 1:45So hopefully that kind of gives you a starting place of where you can kind of
- 1:49look at that and let me know in the comments if you have any other questions.
SHBG and testosterone in perimenopause: what TikTok gets wrong
Quick answer
SHBG elevation is a clinically relevant factor in hormone therapy management, particularly for perimenopausal women using oral contraceptives or thyroid medications, both of which stimulate hepatic SHBG synthesis. Clinicians managing HRT in this population should assess free hormone levels rather than relying solely on total levels when adjusting dosing. Boron supplementation lacks sufficient randomized controlled trial evidence to be recommended as a primary intervention for reducing SHBG.

Page-specific review note
What this exact clip is really saying
This FormBlends review is specific to "SHBG and testosterone in perimenopause: what TikTok gets wrong" from Nurse Kelly. We read the clip as a TRT social video fact-checks claim about Testosterone, then separate the useful signal from what a short social video cannot prove. The page-specific claim focus is: SHBG elevation is a clinically relevant factor in hormone therapy management, particularly for perimenopausal women using oral contraceptives or thyroid medications, both of which stimulate hepatic SHBG synthesis.
The reason this review is not generic is the source wording and the canonical claim label "trt replying to carrie hrt perimenopause hormones menopause shbg." In this clip, the useful excerpt is: "What do you do if you have an high SHBG?" That wording changes the review because it points to Testosterone evidence, safety, and patient-fit context, not a one-size-fits-all protocol.
The source trail for this page is checked against Cardiovascular Safety of Testosterone-Replacement Therapy (2023), Testosterone therapy in men with androgen deficiency syndromes: an Endocrine Society clinical practice guideline (2010), and Functional testosterone deficiency in aging men: Clinical impact, diagnostic pathways, and treatment strategies (2026), plus the creator's own wording. Testosterone decisions still need an eligibility review, medication-interaction screen, access check, and quality-control review before anyone treats a social clip as medical advice.

What to do with this video
Use the clip as a claim to verify, not a treatment plan
What it helps with
- SHBG elevation is a clinically relevant factor in hormone therapy management, particularly for perimenopausal women using oral contraceptives or thyroid medications, both of which stimulate hepatic SHBG synthesis. Clinicians managing HRT in this population should assess free hormone levels rather than relying solely on total levels when adjusting dosing. Boron supplementation lacks sufficient randomized controlled trial evidence to be recommended as a primary intervention for reducing SHBG.
- SHBG binds tightly to testosterone and estradiol, leaving only free fractions biologically active. Total hormone levels without free levels can be misleading if SHBG is high.
- Oral contraceptives containing ethinyl estradiol are among the strongest known pharmaceutical drivers of elevated SHBG, per Plymate et al. (1988, JCEM).
What it may miss
- It may not cover eligibility, contraindications, medication interactions, lab history, or dose escalation.
- Compound access, legal status, and product quality still need a separate safety check.
- Social video captions rarely show the full evidence base behind a claim.
Best next step
Compare the claim against a FormBlends guide, safety page, and licensed-provider review before acting.
Start provider reviewWhat You'll Learn
- SHBG binds tightly to testosterone and estradiol, leaving only free fractions biologically active. Total hormone levels without free levels can be misleading if SHBG is high.
- Oral contraceptives containing ethinyl estradiol are among the strongest known pharmaceutical drivers of elevated SHBG, per Plymate et al. (1988, JCEM).
- The 'free hormone hypothesis' remains debated in endocrinology. SHBG-bound hormone may not be entirely inert in all tissues, so framing SHBG as a simple blocker is an oversimplification.
- Higher hormone dosing to compensate for elevated SHBG is a real clinical strategy, but it requires measurement of free hormone levels specifically and carries its own risk profile that warrants clinical supervision.
- Boron has preliminary evidence for modest effects on sex hormone levels but lacks robust randomized controlled trial data in humans. It is low-risk at standard supplement doses but should not be treated as a reliable fix.
- Liver function and thyroid status should be assessed when SHBG is persistently elevated, since both organs directly regulate SHBG synthesis and underlying pathology may be driving the elevation.
- Insulin suppresses hepatic SHBG production, which explains why obesity typically lowers SHBG while caloric restriction raises it. The relationship between diet and SHBG runs through insulin signaling, not carbohydrate intake alone.

What did @kelly_keelan actually say?
Kelly laid out a practical explainer on sex hormone-binding globulin (SHBG) for a perimenopause audience. The core argument: high SHBG means your hormones are "blocked" and your body can't use them. She listed oral contraceptives, high-dose thyroid medication, prolonged fasting, carb restriction, and stress as causes. Her proposed solutions ranged from lifestyle changes to dosing hormones higher to compensate, with a cautious mention of boron as a supplement that "may" help.
The tone was appropriately hedged throughout. She flagged uncertainty on boron specifically, and acknowledged that some people can't lower SHBG no matter what they do. That kind of epistemic humility is rarer than it should be on health TikTok, and it matters.
