GLP-1 medications have quickly become some of the most talked-about treatments in health and wellness circles. Originally developed for managing type 2 diabetes, these drugs—like semaglutide and liraglutide—are now widely used for weight loss, sparking both enthusiasm and concern. While the results can be impressive, it’s essential to understand how to use these medications safely.
Below, we’ll cover the fundamentals of GLP-1 safety, from evidence-based best practices to a look at some of the newer, buzzworthy trends like supplements and microdosing.
GLP-1 receptor agonists are medications that mimic the action of the glucagon-like peptide-1 hormone, which helps regulate blood sugar and appetite. In the body, GLP-1 stimulates insulin release, suppresses glucagon secretion, and slows gastric emptying—all of which help lower blood sugar and promote a feeling of fullness.
Common FDA-approved GLP-1 medications include:
Originally developed for people with type 2 diabetes, these medications have been increasingly prescribed for chronic weight management, particularly for those with obesity or weight-related health conditions.
Like any medication, GLP-1 receptor agonists come with important safety considerations. These drugs can be highly effective—but only when used under the guidance of a licensed medical provider.
GLP-1 receptor agonists are not recommended for everyone. According to current guidelines, they should be avoided if you are pregnant, hypersensitive to GLP-1, or living with severe gastrointestinal conditions such as inflammatory bowel disease (IBD). They may also be unsafe for individuals with a history of pancreatitis, kidney failure, or gallbladder disease. Additionally, they are not recommended for those at increased risk of certain thyroid cancers.¹
Nausea, vomiting, constipation, and diarrhea are among the most common early side effects. While they often improve with time, they can worsen with improper dosing or if the medication is taken without lifestyle adjustments.¹
Regular follow-ups and lab work help ensure the medication is working effectively and safely. Your provider may monitor weight, blood pressure, glucose levels, and kidney function.
GLP-1 medications are typically started at a low dose and increased slowly to reduce side effects and give your body time to adjust. Skipping ahead or taking a higher GLP-1 dose than prescribed can increase the risk of serious complications.
These medications work best in conjunction with a balanced diet, regular exercise, and proper hydration. Overeating or consuming high-fat meals can worsen side effects like nausea or reflux.
To stay safe while taking GLP-1 receptor agonists, follow these medical best practices:
As GLP-1 medications rise in popularity, so do a number of wellness trends claiming to offer similar benefits—often without the same scientific backing or safety oversight. Here are some of the most talked-about trends and what to keep in mind.
Many over-the-counter products now use “GLP-1” in their marketing, offering gummies or powders that claim to support metabolism or appetite control. These products do not contain real GLP-1 medications and are often built around ingredients like fiber or bitter herbs. Their benefits may be minimal and unproven, and they’re not regulated like prescription drugs.
"Just because a product says 'GLP-1' on the label doesn’t mean it works like a GLP-1 medication. These supplements can create a false sense of security without delivering meaningful results." — Shelly House, FNP-BC
Some are using very low doses of, or “microdosing,” GLP-1 drugs to ease into treatment or reduce side effects. While it’s gaining attention online, GLP-1 microdosing isn’t medically recommended and can lead to reduced effectiveness or unpredictable outcomes without professional guidance.
"Misuse of GLP-1 medications through microdosing bypasses clinical safeguards, elevating the potential for adverse events and long-term metabolic instability." – Shelly House, FNP-BC
Unprescribed or compounded GLP-1 medications are increasingly being used without medical oversight. This can involve mixing drugs, incorrect dosing, or obtaining meds through unofficial channels—all of which raise serious safety concerns.
"Using GLP-1s without proper oversight opens the door to serious health risks, especially when people mix medications or skip essential monitoring." — Shelly House, FNP-BC
Trends like intermittent fasting, high-fiber diets, and gut health routines are promoted as ways to “boost GLP-1 naturally.” While some of these habits support overall health, they don’t replace medication when it's clinically needed.
"Lifestyle habits like eating more fiber or fasting can support overall health, but they don’t replace GLP-1 medications when someone truly needs them." — Shelly House, FNP-BC
From understanding how GLP-1 medications work to recognizing the importance of proper dosing, supervision, and lifestyle support, it’s clear that safety should be at the core of any treatment plan. While trending supplements and DIY tactics may seem appealing, they can’t replace the clinical expertise and oversight required for real, lasting results.

The Psychology of a Fresh Start: Why January Boosts Motivation
Every January, people feel a surge of motivation — a desire to improve routines, break old habits, start new ones, and aim for better health. This isn’t coincidence, and it isn’t simply “New Year energy.”
It’s a well-documented psychological phenomenon called The Fresh Start Effect.
The Fresh Start Effect describes how certain dates — like the first day of a new month, your birthday, or the start of a new year — create a mental reset. These moments feel like a clean slate, giving your brain permission to leave old patterns behind and step into a new version of yourself.
Understanding how and why this effect works not only makes January feel less mysterious — it helps you use this mental momentum to create habits that actually last.

Winter Home Safety Checklist: Carbon Monoxide, Space Heaters & Humidifiers
Winter is the season when home safety matters most. As temperatures drop, we spend more time indoors and rely on heaters, fireplaces, and appliances that can introduce hidden risks. Carbon monoxide levels rise, space heater accidents become more common, and even well-intentioned humidifier use can release irritants if not cleaned properly.
The good news:
Most winter safety checks take under 10 minutes and prevent the majority of cold-weather home hazards.
Here’s what to watch for — and the simple steps that protect your home and your health all season long.

Why Your Hair Falls Out More in Winter
If you’ve noticed extra shedding in the shower, on your pillow, or in your brush during the winter months, you’re not imagining it. Hair loss often increases in fall and winter, and the reasons have less to do with genetics and more to do with seasonal stress on the scalp, hormones, and overall health.
Winter changes your environment in ways that quietly affect the hair growth cycle. Understanding what’s happening inside your body can help you prevent shedding — and support healthier, stronger hair.
Cold, dry air pulls moisture out of your skin and hair. Because the hair shaft loses hydration faster in low humidity, strands become:
brittle
frizzy
prone to breakage
more likely to split
This isn’t true “hair loss” from the root — but breakage can mimic shedding.
Indoor heating makes it worse by lowering humidity even more, leading to dry scalp and fragile strands.
A dry scalp can become:
itchy
flaky
inflamed
Inflammation disrupts hair follicles, pushing more strands into the telogen (shedding) phase of the cycle.
Conditions like dandruff and seborrheic dermatitis flare in winter, which accelerates shedding.
Vitamin D plays a direct role in hair growth. In winter, sunlight exposure drops drastically, and vitamin D levels fall.
Low vitamin D is strongly linked to:
increased shedding
slower regrowth
weaker hair follicles
Many people don’t realize that winter hair loss can be a simple reflection of seasonal vitamin D deficiency.
Cold weather shifts appetite and habits. People tend to eat:
fewer fruits and vegetables
fewer protein-rich meals
more carb-heavy or comfort foods
Hair is made of keratin — a protein — so inadequate protein quickly affects the growth cycle.
Even small nutritional shifts can trigger telogen effluvium, a temporary but noticeable shedding phase.
Winter brings:
colds
flu
RSV
COVID
increased stress
poor sleep
Any illness or major stressor can trigger hair shedding 2–3 months later.
This means March hair loss might actually come from a December flu.
Winter also increases cortisol levels due to less sunlight and more indoor time, which contributes to hair cycle disruption.
Most people drink less water in winter.
But dehydration affects:
scalp health
oil production
hair shaft strength
follicle function
A dehydrated scalp can’t support healthy growth, and the hair becomes brittle and prone to breakage.
Studies show humans shed slightly more hair in fall and winter — an evolutionary response to thicker summer growth and colder weather patterns.
Seasonal shedding is normal, but winter stressors can intensify it.
