Our collagen peptides for weight loss perfectly complement a calorie-controlled diet and well-rounded exercise routine to help you lose weight. And keep it off.

Your body doesn’t like leaving its comfort zone. It wants to stay at your current weight — and will rebel whenever you try to slim down. How? With intense hunger and slowed metabolism. But you’re not powerless. You can use our collagen supplements to outsmart your physiology.

Increases your body’s level of satiety (i.e., fullness) hormones

As a protein, collagen could help increase your body's level of satiety hormones, including glucagon-like peptide-1 (GLP-1) and cholecystokinin. It could also suppress the hormone ghrelin, the sneaky culprit responsible for those intense hunger feelings.

Bottom line? Collagen supplementation could help you feel fuller for longer. This prevents you from giving in to those sneaky, all-consuming food cravings (read: extra calories you don’t need!) that always attack when you're most vulnerable.

Promotes calorie-burning
muscle mass

Collagen peptides provide your body with the amino acids it needs to grow and maintain muscle, which burns approximately 8 more calories per kilogram than fat.

The more muscle mass you have, the more calories you burn — and the closer you’ll be to your goal weight.

Reduces the development and accumulation of fat cells

Regardless of how much weight you lose, your fat cells never disappear. Instead, they only shrink in size, lingering in your tissues, desperate and primed to get bigger again.

Thankfully, collagen peptides can help you actively fight against fat regain. They do so by preventing the development of new fat cells and fat accumulation within existing fat cells, ultimately leading to better weight management.

FAQs

  1. Our collagen Glow Shakes promote feelings of fullness, which can help you maintain a calorie deficit. As a protein, collagen can increase the body’s levels of satiety while reducing levels of ghrelin, the hormone responsible for hunger. This helps curb cravings and reduce overall calorie intake. Additionally, collagen powder supports muscle growth, which increases calorie burning. This makes our powder some of the best collagen for weight loss available, helping you get closer to your goals.

  2. Yes, collagen supplements like our Glow Shakes can help reduce body fat. Collagen peptides prevent the development of new fat cells and limit fat accumulation in existing cells, making it easier to manage weight and prevent fat regain. By helping you maintain muscle mass, collagen also supports a higher calorie burn, further aiding in fat reduction.

  3. Add Glow Shakes into your daily routine by mixing it into your water for a delicious milkshake. Collagen peptides work best as part of a calorie-controlled diet and regular exercise routine, supporting your health journey by helping you feel full and promoting muscle growth for a higher metabolism.

  4. Hydrolyzed Collagen Peptides are ideal for losing weight. This form of collagen is easily absorbed by the body and effectively supports satiety, muscle maintenance, and fat management, all essential components of a successful weight loss plan.

  5. Results from collagen supplements can vary, but many people begin noticing benefits within a few weeks of consistent use, with reduced cravings, increased satiety, and improved muscle tone. For best results, collagen should be taken daily and combined with a healthy diet and regular exercise.

  6. Yes, our Glow Shakes can help with appetite control. As a protein, collagen increases the levels of fullness hormones (GLP-1 and cholecystokinin) and decreases ghrelin levels, helping you feel full for longer. This can reduce cravings and prevent unnecessary snacking, making it easier to stick to a calorie-controlled diet. It’s for this reason that our Glow Shakes are some of the best collagen powder for weight loss available.

  7. Yes, our Glow Shakes are safe to use alongside other weight loss supplements. However, it’s always best to consult your healthcare provider before combining supplements, especially if you have specific dietary needs or are taking other medications.
