Best GLP-1 for Weight Loss Over the Counter: What Science Really Says (2026)

By Dr Frank Yap, MD -

Introduction

GLP-1 (glucagon-like peptide-1) drugs like Ozempic and Wegovy are prescription medications known for weight loss. Many people ask: “What is the best GLP-1 for weight loss over the counter?”

The short answer: There are no OTC drugs that act directly as GLP-1 receptor agonists. However, certain dietary strategies, lifestyle habits, and supplements can modestly support your body’s own GLP-1 secretion.

1. Why Over-the-Counter GLP-1 “Drugs” Don’t Exist

  • GLP-1 receptor agonists are prescription-only.

  • They mimic GLP-1 and resist enzymatic breakdown.

  • They produce substantial weight loss (10–15% body weight).

  • They require medical supervision due to potential side effects such as nausea, pancreatitis, or thyroid issues.

⚠️ Important: Any OTC product claiming to be a “GLP-1 drug” is not legitimate and should be avoided.

2. Natural GLP-1 Support: Dietary Strategies

Protein-Rich Foods

  • Stimulate GLP-1 release after meals.

  • Sources: eggs, fish, lean meats, whey protein, legumes.

Dietary Fiber and Resistant Starches

  • Fermented by gut bacteria into short-chain fatty acids (SCFAs), which stimulate GLP-1.

  • Sources: oats, barley, beans, cooled potatoes, green bananas.

Healthy Fats

  • Monounsaturated fats (olive oil, avocado, nuts) support GLP-1 signaling.

  • Combining protein, fiber, and healthy fats produces stronger post-meal satiety.

3. Thylakoids (Spinach Extracts)

Benefits:

  • Delay fat digestion.

  • Increase nutrient contact with gut L-cells.

  • Stimulate GLP-1, CCK, and PYY.

  • Reduce ghrelin (hunger hormone).

Safety Caution:

  • Spinach is high in oxalates, which may worsen kidney stones or chronic kidney disease (CKD).

  • Patients with kidney issues should consult a healthcare provider and consider low-oxalate greens (kale, romaine).

Evidence:

  • Small human trials show thylakoids can reduce hunger and produce modest weight loss when paired with a healthy diet.

4. Lifestyle Approaches

  • Exercise: Moderate-to-vigorous activity increases post-meal GLP-1 and improves insulin sensitivity.

  • Sleep: 7–9 hours of quality sleep supports hormone balance.

  • Stress Management: Yoga, meditation, and mindfulness prevent cortisol-related appetite dysregulation.

5. Over-the-Counter Supplements Often Marketed for GLP-1 Support

Although OTC supplements cannot replicate prescription GLP-1 drugs, some may modestly support natural GLP-1 secretion:

  • Spinach Thylakoid Extracts: Shown in small trials to increase GLP-1 and satiety.

  • Berberine: Improves insulin sensitivity, indirectly supporting GLP-1 signaling.

  • Green Tea Extract: May help suppress appetite slightly; evidence for GLP-1 is limited.

  • Probiotics: Certain strains may support gut health and the gut–GLP-1 axis; effects vary between individuals.

Key point: These supplements support natural GLP-1 signaling but are not substitutes for prescription drugs.

6. Realistic Expectations

  • Natural GLP-1 support can improve appetite control and metabolic health.

  • Weight loss effects are modest compared to prescription medications.

  • OTC strategies are safe and sustainable but slower in producing results.

Conclusion

There is no over-the-counter GLP-1 drug that can replicate prescription medications. The best GLP-1 for weight loss over the counter refers to safe, evidence-based approaches:

  • Protein, fiber, and healthy fats in your diet

  • Thylakoid-rich greens (with caution for kidney health)

  • Exercise, sleep, and stress management

  • Certain OTC supplements that modestly support GLP-1

These strategies are safe, effective, and supportive of long-term metabolic health.

Best Vitamin D3 + K2 Supplements in 2026: Doctor-Reviewed Picks for Bone, Heart & Immune Health

By Dr Frank Yap, MD -
Image
Vitamin D3 and Vitamin K2 are two of the most commonly deficient—and misunderstood—nutrients today. While Vitamin D improves calcium absorption, Vitamin K2 determines where that calcium actually goes . That’s why taking Vitamin D without K2 may be incomplete—and in some cases counterproductive. After reviewing ingredient quality, dosing accuracy, brand transparency, and real-world user feedback, the following are the best Vitamin D3 + K2 supplements available in 2026 . Most people in the United States consume less than recommended amounts of vitamin D . An analysis of data from the 2017–2018 National Health and Nutrition Examination Survey (NHANES) found that average daily vitamin D intakes from foods and beverages were 4.3 mcg in men, 3.8 mcg in women, and 5 mcg (200 IU) in children aged 2–19 years ( NHANES 2017 - 2018 ). Why Trust This Guide? This review prioritizes supplements that meet four non-negotiable criteria : Uses Vitamin D3 (cholecalciferol) — not D2 Includes Vitam...

Ivermectin and Fenbendazole in the Treatment of Psoriasis? A Case Series of 13 Patients (2026)

By Dr Frank Yap, MD -
Image
Abstract Psoriasis is a chronic autoimmune condition affecting approximately 7.5 million individuals in the United States, with significant economic, physical, and psychological burdens. This case series reports on 13 patients who experienced notable improvements in psoriasis symptoms following treatment with ivermectin and/or fenbendazole, antiparasitic agents repurposed for this indication. Cases were derived from self-reported testimonials shared on social media platforms. Treatment durations ranged from 3 days to 3 months, with dosages varying between 6 mg ivermectin twice daily and combinations with fenbendazole. Rapid resolution of skin lesions was observed in most cases, with some achieving near-complete clearance. While these anecdotal reports suggest potential therapeutic efficacy, controlled clinical trials are warranted to validate these findings and elucidate underlying mechanisms. Introduction Psoriasis is a chronic inflammatory disorder characterized by hyperproliferation...

A meta-analysis of 3 studies (C19early 2025) concluded that CPC (CetylPyridinium Chloride) may significantly lower risk with  viral clearance . One study shows significant benefit. Meta analysis using the most serious outcome reported shows 83% [6‑97%] lower risk . Results are consistent with early treatment being more effective than late treatment. A study, published in Nature ( Takeda 2022 ) concluded that CPC (CetylPyridinium Chloride) may inhibit SARS-CoV-2 infection even at lower concentrations. Another team of international scientists has also demonstrated the usefulness of cetylpyridinium chloride-containing mouthwashes in inhibiting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and reducing the risk of viral transmission. The study is published in the Journal of Medical Microbiology (2022). A scientific review, published in the  Journal of Formosan Medical Association  (2022) also concluded that mouthwash containing CPC shows potential fo...

17 Best Natural Ozempic Alternatives 2026 (Resource Guide)

By Dr Frank Yap, MD -
Image
Some of the best natural alternatives to Ozempic include berberine, a supplement that has shown potential in managing blood sugar and promoting weight loss, often referred to as “nature’s Ozempic” in wellness communities. High-fiber foods also play a crucial role by helping to control appetite and improve metabolic health. Other natural options include psyllium husk, which provides soluble fiber supporting satiety and digestive health, and curcumin, known for its anti-inflammatory properties, which may aid metabolic balance. Additionally, green tea extract, magnesium, protein-rich foods, and lifestyle factors like adequate sleep and stress reduction contribute to weight management.  However, none of these natural alternatives are as potent or fast-acting as Ozempic itself, and their effects can vary widely among individuals. It is important to consult a healthcare provider before starting any supplement regimen, especially for managing blood sugar or weight loss. The 2023 rep...

If you’re considering injectable medications for weight loss or type 2 diabetes , you’ve probably heard of Ozempic, Wegovy, Mounjaro, and Zepbound . These drugs are reshaping obesity and diabetes care, but with multiple options on the market, it can be confusing to know which is best for your goals. In this guide, we break down each medication, compare their weight-loss potential, diabetes benefits, and side effects — all in a simple, easy-to-digest format. What These Drugs Are & How They Work All four medications are injectables , but they differ in mechanism, dosage, and approval purpose : Ozempic & Wegovy: Both contain semaglutide , a GLP-1 receptor agonist.

It’s natural to have complex feelings about noticing signs of aging. You can embrace the beauty and privilege that it is to age, while also not love all of the physical changes that come along with it.  If you’d like to soften these signs but don’t want to go the injectables route, there are non-invasive products that can help. In the world of beauty products, there's perhaps no category more saturated than the anti-aging market. What to Look for in an Anti-Aging Product a. Vitamin C An antioxidant powerhouse, vitamin C is directly involved with collagen production in the body. Vitamin C is beneficial in anti-aging products for several reasons: It protects skin from environmental stressors, promotes cell turnover, and can fade dark spots which contribute to the appearance of aging skin. Products containing vitamin C can irritate sensitive skin, so be sure to start out using a low concentration if your skin is reactive. b. Retinoids Retinoids are a category of ingredients, and retin...

GLP‑1 Drugs for Alzheimer’s Disease: Can Semaglutide and Liraglutide Reduce Dementia Risk? (2026 Evidence Review)

By Dr Frank Yap, MD -
Image
Quick Take GLP‑1 receptor agonists (such as semaglutide, liraglutide, dulaglutide) are not approved treatments for Alzheimer’s disease (AD). However, growing epidemiologic, preclinical, and early clinical evidence suggests they may reduce Alzheimer’s risk and slow cognitive decline indirectly by improving insulin signaling, neuroinflammation, vascular health, and mitochondrial function. This article reviews the science without hype — what looks promising, what’s proven, and what remains unknown. Why GLP‑1 Entered the Alzheimer’s Conversation Alzheimer’s disease is increasingly understood as a metabolic–inflammatory brain disorder , not just an amyloid problem. Hallmarks include: Brain insulin resistance (“ type 3 diabetes ” hypothesis) Mitochondrial dysfunction Chronic neuroinflammation Cerebrovascular impairment GLP‑1 drugs were originally developed for type 2 diabetes but have systemic effects highly relevant to AD pathophysiology.

In recent weeks and months, several publications and studies have suggested that maintaining adequate levels of vitamin D would seem potentially beneficial in fighting the COVID-19 infection. How do you know that your vitamin D level is adequate? Most people in the United States consume less than recommended amounts of vitamin D. An analysis of data from the 2015–2016 National Health and Nutrition Examination Survey (NHANES) found that average daily vitamin D intakes from foods and beverages were 5.1 mcg (204 IU) in men, 4.2 mcg (168 IU) in women, and 4.9 mcg (196 IU) in children aged 2–19 years ( NHANES ). What Is Vitamin D? Vitamin D is a fat-soluble vitamin, meaning that it dissolves in fats and oils and can be stored in your body for a long time. Vitamin D is important to the body in many ways. It helps the body absorb calcium from food and supplements. Muscles need it to move, for example, nerves need it to carry messages between the brain and every body part, and the immune syste...
