Weight Loss Supplements

What Weight Loss Supplements Can (and Can’t) Do

No supplement melts fat on its own, that's the honest answer. The best supplements for weight loss help your body get what it needs while you eat a little less and move a little more. That makes the habits behind real results easier to keep.¹

What They Can Help With

• Feeling full longer: Protein and fiber take longer to digest. Higher-protein meals are linked to greater fullness, which makes a calorie deficit easier to live with.^2,3 A protein shake or a daily fiber supplement covers both.
• Protecting muscle: When you eat less, your body can break down muscle along with fat. Enough protein helps you keep lean muscle, and muscle burns more calories at rest than fat does.²
• Supporting metabolic health: Berberine and chromium support healthy glucose metabolism, which affects how steady your energy feels through the day. The NIH notes that chromium may lead to a very small loss of weight and body fat.¹*
• Filling nutrition gaps: Less food on your plate can mean fewer vitamins and minerals. A daily multivitamin covers the basics.
• Keeping weight off: Losing weight is one challenge. Keeping it off is another. Research on the gut microbiome, the trillions of bacteria in your digestive tract, is opening a new path here. UltraFlora® Healthy Weight with Akkermansia uses a strain studied for weight maintenance after weight loss.⁴† UltraFlora® Control is a probiotic shown to help control body fat and body weight.*

What They Can’t Do

• Replace a calorie deficit, good sleep, or regular movement.
• Deliver results overnight. Supplements that help you lose weight work over weeks and months of steady use.
• Stand in for medical care. If you manage a health condition, take prescription medication, or use a GLP-1 medication, talk with your healthcare provider before adding a supplement.

What to Expect With Weight Loss Supplements

Think of a weight loss supplement as a slow build, not an on switch. Progress depends on your starting point, your routine, and how consistent you are. Here is what the path usually looks like.

Getting Started

Pick one or two products that match your main goal and take them at the same time each day. If you add fiber, start with a small serving and work up over a week, with plenty of water, so your gut can adjust. A protein shake can make it much easier to hit your daily protein target on busy days.

Building Consistency

The scale will go up and down from day to day. That is normal. Track a few other signals too: how full you feel after meals, how your clothes fit, your energy, and your strength in the gym. These often change before the number on the scale does.

Keeping It Off

Maintenance is where many plans stall. That holds whether you're finishing a structured diet, transitioning off keto, or stepping down from a GLP-1 medication with your provider. Protein, fiber, and gut support can all help you hold on to your results.

In a 2026 randomized controlled trial, adults who had lost at least 8% of their body weight on an eight-week diet took either the pasteurized Akkermansia strain in UltraFlora® Healthy Weight or a placebo for 24 weeks. The Akkermansia group regained 1.2 kg on average, compared with 3.2 kg on placebo. That's a difference of about 2 kg, or roughly 4 lbs.⁴† Read more about Akkermansia.
