What Your Blood Says About Your GLP-1

GLP-1s can help with weight loss, perimenopause symptoms, and metabolic health. But oftentimes, the results show up in your biology long before you feel them. Rythm tracks the biomarkers that shift on a GLP-1 so you can see what's actually changing inside, not just on the scale.

METABOLIC HEALTH

01

See what's driving your weight loss

The scale only tells part of the story. GLP-1s change how your body handles blood sugar, insulin, and fat storage, and sometimes those shifts can be dramatic. Rythm tracks markers like fructosamine, triglycerides, HDL, and ApoB on a monthly basis so you can learn whether the changes happening beneath the surface are actually moving your health in the right direction.

HORMONE BALANCE

02

Learn how your hormones are shifting

Rapid weight loss, perimenopause, and GLP-1s all pull on the same hormonal levers. Estradiol, progesterone, and SHBG, can swing in ways that affect your mood, sleep, cycle, and energy. Rythm helps you see these changes month over month so you can tell what's the medication, what's your cycle, and what needs attention.

THYROID & ENERGY

03

The thyroid factor most women miss

Thyroid issues are common in women, and weight changes, fatigue, and brain fog on a GLP-1 can mask them. Tracking TSH, and free T3 helps you see whether your thyroid is keeping up with the changes your body is going through, so you can connect how you feel to what's actually going on.

MUSCLE & NUTRITION

Keep your strength as the weight drops

Rapid weight loss can include muscle loss, especially when protein, resistance training, and recovery are not keeping up. Rythm helps you follow markers tied to metabolism, recovery, inflammation, lipids, and long-term health, so your progress is grounded in data, not just the scale.

Stay proactive about long-term health

When appetite drops, nutrient intake can drop too. Protein, iron, vitamin B12, vitamin D, and overall fuel can all become harder to keep up with. Rythm tracks markers connected to energy, iron status, nutrient status, and inflammation, so you can lose weight without flying blind.

What our customers using GLP-1s are saying

Great way to manage health

Since I’m on GLP-based medication, having this level of visibility feels especially important. It gives me more confidence that I’m staying on top of my health and not missing anything. I also like that I can easily share the results with my doctor. It gives them a much clearer picture between visits, especially when we’re looking at smaller trends that would normally go unnoticed with standard annual labs.

Super easy, really insightful

Being on a GLP-1 made me realize how little visibility you normally get into your health between doctor visits. The whole experience was incredibly easy and honestly just gave me a lot more peace of mind.

Good to have while losing weight

I went on a GLP-1 mostly to lose weight, but after a couple months I started wondering how it was affecting my energy, recovery, and testosterone. Rythm made it really easy to keep an eye on everything without needing to book a bunch of appointments.

FAQ

How is Rythm different?

Most blood testing companies charge $500 or more for a single test per biomarker, providing only a one-time snapshot that doesn’t capture your long-term health trends or reflect your true baseline. This approach can lead to missed patterns or even misdiagnoses due to limited data. Rythm takes a different approach, using monthly tracking to build a detailed picture of your health over time. This allows for more accurate insights, better optimization, and a clearer understanding of how your body is evolving.
