Are you ready to feel empowered to make informed decisions about weight loss supplements? As interest in medical weight loss and supplements continues to grow, many people in Winter Haven and throughout Polk County are asking which weight loss supplements actually work and which ones to avoid.
At the Institute of Eternal Youth Aesthetics & Wellness in Winter Haven, we regularly speak with patients who want to lose weight safely and sustainably. This blog breaks down three of the most popular ingredients in weight loss supplements—green tea extract, chitosan, and berberine—and provides you with the key insights you need to choose with confidence. Plus, you’ll learn how to spot potential risks while deciding which vendor to buy from.
Top Weight Loss Ingredients You Should Know
1. Green Tea Extract and Weight Loss
Green tea extract is one of the most common ingredients found in weight loss supplements.
It contains two compounds believed to support calorie and fat metabolism:
-
EGCG (epigallocatechin gallate)
-
Caffeine
Together, EGCG and caffeine may slightly increase calorie burning and fat metabolism.
Research suggests modest results when taken consistently. Studies typically use doses of:
-
576–886 mg catechins
-
70–200 mg caffeine daily
-
over 12–24 weeks
Green Tea Extract Safety Considerations
While green tea itself is generally safe, high doses of concentrated extracts can carry risks. Daily intake of 800 mg or more of EGCG has been linked to elevated liver enzymes, which may signal potential liver damage.
We encourage patients to stay within recommended doses and choose high-quality, certified products, which will help protect their overall health, such as those we offer at The Institute of Eternal Youth Aesthetics & Wellness, by Evexias Health Solutions.
2. Chitosan: The “Fat Blocker”
Chitosan is often marketed as a fat-blocking supplement.
Chitosan is derived from chitin, a natural fiber found in shellfish shells.
Some clinical studies suggest that chitosan may offer a small weight-loss advantage, averaging about 1 kg (2.2 lbs) more than placebo.
However, the effect of chitosan is generally modest and works best when combined with:
-
A calorie-controlled diet
-
Healthy lifestyle habits
-
Consistent physical activity
Chitosan Safety Considerations
For most patients, chitosan is generally considered safe when taken at:
-
Doses of 1 – 1.35 grams per day
-
For up to three months
However, individuals with shellfish allergies should avoid chitosan supplements entirely.
Always review supplement labels carefully before use.
3. Berberine: The So-Called “Nature’s Ozempic”
Berberine has recently gained significant attention online as a natural alternative to semaglutide (Ozempic). Why? Because berberine appears to stimulate GLP-1 secretion, which may play a role in blood sugar control and appetite regulation, potentially helping with weight loss.
However, it’s important to keep expectations realistic.
Current research suggests modest weight-loss results, typically averaging about 2 kilograms (4–5 pounds) over 6 months. Common doses studied range from 300 mg – 1500 mg daily.
Medication Interaction Risks of Berberine
Though generally safe within proper guidelines, be mindful of drug interactions. Berberine inhibits enzymes like CYP3A4, 2C9, and 2D6, which might alter the effects of certain medications.
The Biggest Risk With Weight Loss Supplements
Many people are surprised to learn that weight loss supplements are one of the highest-risk categories in the supplement industry.
Some weight loss supplements have been found to contain:
-
Undeclared stimulants
-
Hidden ingredients
-
Inaccurate labeling
That’s why physician-guided supplement programs are essential.
At The Institute of Eternal Youth Aesthetics & Wellness in Winter Haven, we have carefully selected supplements from Evexias Health Solutions, which are third-party certified for safety and quality, and can be purchased in our Winter Haven Office. Supplements from reputable medical suppliers help ensure safety, quality, and transparency.
If You’re Considering Weight Loss Supplements
Before starting any supplement, ask yourself:
-
Is the product third-party tested?
-
Are the ingredients supported by clinical research?
-
Could it interact with medications?
-
Have you discussed it with a qualified healthcare professional?
Taking the time to evaluate these factors can help protect your health and support better long-term results.
A Smarter Approach to Weight Loss in Winter Haven
While supplements may offer small benefits, they are rarely the most effective solution on their own.

-
