From The Manufacturer

WHY IS MARINE COLLAGEN BETTER? - Unlike bovine collagen, marine collagen only consists of Type I collagen that makes up 90 percent of your hair, skin and nails. Marine collagen comes from fish and has the smallest particle size as well as lowest molecular weight of all the other collagen types. In fact, marine collagen is absorbed 1.5 times more efficiently than other collagens! Has no fishy smell or taste. Small capsules, easy to swallow! REJUVENATE SKIN, HAIR, AND NAILS & STRENGTHEN BONES - Collagen is the most abundant protein in our body. After 25, our collagen levels start to drop by 1-2% each year. Marine collagen is known for its anti-aging benefits, our premium Non-GMO & Gluten-Free collagen can help you decrease wrinkles, moisturize skin, reduce signs of aging, strengthen hair and nails. Like other collagens, marine collagen also supports stronger joints and bones while aiding in digestion and gut health. HIGHER EFFICACY - Our USA factory uses advanced Enzymolysis Technology so it does not destroy the natural chemical structure of collagen peptides. Collagen peptides are available in various sizes, our marine collagen is hydrolyzed to a low 1000 Dalton molecular weight for maximum bioavailability. This leads to enhanced absorption with more effective results. NATURAL SOURCE - FITINDEX Marine Collagen is sourced from Wild-Caught Deep Sea Fish Skin, which is naturally rich in Collagen, NOT the cheaper fish scales. Beware of some marine collagen on the market that is from farmed fish, bred in cramped conditions, exposed to high concentrations of harmful substances. JUST TRY IT - We stand behind our products with confidence. We fully understand the uncertainty of trying new supplements, if you have any problems with our products, please let us know and we will make things right in time!

An Overview On Marine Collagen Protein Powders

Collagen is essential to life and responsible for so many functions within the body. It’s found in everything from your blood vessels to your teeth and it provides structure to your skin, bones and muscles. If your body isn’t making enough collagen on its own, you may want to consider adding a marine collagen protein powder to your diet to give your collagen levels a boost.

The most important thing when shopping for marine collagen protein powder is choosing a brand that uses quality ingredients. Consider brands that source their wild-caught deep-sea fish from the North Atlantic waters. Keep in mind that farm-raised fish are often injected with hormones and fed antibiotics.

Next, you want to examine the product label to further validate its quality. This is important because you want to give your body the best support possible.  Some companies also have their collagen protein powder voluntarily tested by a third-party tested, so you can feel good about buying it.

Make sure the marine collagen protein powder you select works with the diet you are currently following. Some powders are physician-formulated and can be used with a wide range of diets, including gluten, dairy and sugar-free. Others may be non-GMO and certified Paleo, keto, kosher and halal-friendly.

Finally, check the nutrition label to see exactly what you’re getting with each serving of marine collagen protein powder. For example, one bottle may offer 5 grams of collagen, 4.7 grams of protein, 5 grams of hydrolyzed collagen peptides and 10 essential amino acids.

The Marine Collagen Protein Powder Buying Guide

  • Always contact your doctor before beginning any new supplement. This is especially important for pregnant and nursing mothers, individuals with underlying health conditions and anyone taking medication.
  • Marine collagen protein powder may cause digestive issues in some individuals. If you experience this, discontinue use and consult with your family physician.
  • Marine collagen protein powder is not safe for individuals with shellfish or other marine allergies.
  • Always keep any and all supplements out of the reach of children. Even if the supplement is made of natural ingredients, it can have side effects when more than the recommended amount is taken.
  • Store your marine collagen protein powder at room temperature in a cool dry location. Moisture can cause the powder to clump and become unusable.
  • When shopping for the best marine collagen protein powder, determine how much you’re paying per ounce, as each container may come in a different size. The AMANDEAN Collagen Protein Supplement is one of the most affordable brands, while the CORREXIKO Hydrolyzed Protein Powder is more moderately priced. At the top of the price range are formulas that use 100% Norwegian cod sourced from the North Atlantic waters.
