At Eltham Pharmacy, we understand how challenging the journey to weight loss can be. With so many products on the market claiming to offer fast and effortless results, it’s easy to get overwhelmed. Among these options, the best weight loss capsules often generate curiosity—and confusion. Are they truly effective? Are natural options always safer? Can capsules alone lead to long-term weight loss?
In this blog post, we’ll set the record straight by debunking common myths and presenting facts that can help you make informed decisions. If you’re considering capsules as part of your weight management plan, it’s essential to know what to expect—and what not to.
Myth 1: Capsules Alone Are Enough to Lose Weight
Fact: Weight loss capsules are not a magic solution. While some may contain clinically studied ingredients that support fat metabolism, appetite suppression, or energy levels, they are most effective when used alongside a balanced diet and regular physical activity.
At our pharmacy, we’ve seen clients achieve the best results when capsules are used as part of a broader lifestyle change. Think of them as tools—not miracles. Without nutritional changes or increased activity, most capsules will have limited long-term impact.
Myth 2: “Natural” Means No Side Effects
Fact: The term “natural” is often used to suggest safety, but it doesn’t guarantee the absence of side effects. In fact, several plant-based compounds found in popular weight loss supplements—such as green tea extract, bitter orange, or raspberry ketones—can interact with medications or cause unwanted symptoms like headaches, digestive upset, or increased heart rate.
That’s why speaking to a healthcare professional before starting any supplement is crucial. At Eltham Pharmacy, we offer personalised consultations to help you choose the best weight loss capsules that suit your medical history and goals.
Myth 3: All Weight Loss Capsules Work the Same Way
Fact: Capsules can differ dramatically in how they support weight loss. Some aim to block fat absorption (e.g. orlistat), others suppress appetite, and some claim to increase your metabolic rate. Understanding how each works is essential before choosing one.
We help our customers differentiate between prescription options, such as orlistat, and over-the-counter products that may use natural extracts or stimulants. Depending on your lifestyle and health status, the most suitable capsule may vary—and sometimes, a capsule might not be the right option at all.
Myth 4: You Can’t Trust Pharmacy-Based Capsules
Fact: Many people assume that pharmacy-sold weight loss products are weaker or less effective than those marketed online or through influencers. In truth, pharmacy-grade capsules go through far stricter regulatory checks in the UK.
When you purchase from a trusted provider like Eltham Pharmacy, you’re getting a product that meets national safety and efficacy standards. We only stock products with proven ingredients and provide advice tailored to your health needs.
Myth 5: If it works for someone else, it will work for me
Fact: Weight loss is highly individual, and so is your response to supplements.
>Your age, gender, metabolism, medical history, hormone levels and even gut microbiome can influence how your body responds to weight loss capsules. Just because a friend lost weight on a particular supplement doesn’t mean you’ll see the same results.
The best weight loss capsules for you will depend on your personal circumstances. Our team at Eltham Pharmacy can help tailor a weight management approach that fits your needs and goals – whether that includes supplements or not.
Myth 6: Capsules Are Just as Effective as Injections
Fact: While capsules may support mild to moderate weight loss, weight loss injections—such as those containing GLP-1 receptor agonists like semaglutide—have shown significantly greater success in clinical trials, especially for individuals with obesity or related health conditions.
As part of our weight loss clinic in London, we offer consultations for weight loss injections. We have already helped many patients achieve more substantial and sustainable results – and you could be next!
While injections may not be suitable for everyone, they’re often a more effective solution for those needing additional medical support.
