Best Marine Collagen Supplements

As you grow older, the levels of different types of collagen in your body begin to decline and this can result in digestive issues, joint pains, muscle weakness, and aging of the skin. You may be able to combat these effects by taking natural marine-origin collagen supplements.

Collagen is a protein found in abundance in your body. It is responsible for the structural integrity of your skin, muscles, tendons, and joints. Marine-origin collagen pills have the same effects as regular collagen supplements but these are more readily absorbed by your body.

If you are beginning to see the effects of aging on your body, you should consider taking these supplements.

What Is Marine Collagen?

Marine collagen is made by extracting collagen from fish skin, bones and scales.

Marine collagen is available in the form of capsules, drinks, powder, tablets, and creams. You can either take a shot of the drink or mix the powder in your smoothies or water. If you want to experience the benefits of the protein related to the skin, then you can directly apply it to your skin instead of eating them. Several beauty products and facial creams contain hydrolyzed marine collagen peptides as their key ingredient.

That is why marine collagen is an ingredient in many cosmetic products. Although it does not penetrate the skin when applied alone, it can be used as an adjunct to other active antioxidants to both moisturize and minimize free radical-induced collagen loss.

These supplements in the form of capsules and tablets are also recommended as they contain a concentrated form of protein. You can start taking these supplements to find out and experience the benefits of these peptides firsthand.

Does Marine Collagen Work?

Marine-origin collagen peptides were only recently introduced as substitutes for bovine and other forms of animal-based supplements.

However, the efficacy of both products is the same. They increase the hydration levels of the skin along with its thickness even after only using them for a short period of time.

In its natural form, it acts as a stimulant and increases the collagen levels and the levels of other amino acids in your body, which improve the functioning and aesthetics of your body 1.

In fact, marine-based collagen is the new staple ingredient of many anti-aging skin care products due to its several benefits. Let's take a look at the detailed benefits this supplement can offer to you.

Benefits of Marine Collagen

Marine-origin collagen supplements have several health benefits, which is exactly why they have become so popular in the last few years. These peptide powders, pills, and capsules are able to improve your general health as they target and repair different aspects of the body. Some of the most important benefits include:

  • Increased bone strength: A study conducted by Yi Yang et al. found that the combination of calcium aspartate and marine fish collagen oligopeptide has a significant effect on increasing bone mineral density, also indicating that marine fishbone oligopeptide could promote absorption of calcium aspartate 2. Thus, taking supplements regularly increases bone strength by increasing the absorption of calcium, which is essential to maintain bone mineral density.

  • Firmer and rejuvenated skin: These dietary supplement pills increase the structural integrity of the skin and promote skin repair and healing. This eventually results in refreshed and toned skin that will knock years off your age. Chiara de Luca et al., 2016 in their study to evaluate the effects of marine-origin collagen on skin found that the supplementation remarkably improved skin elasticity, sebum production, and dermal ultrasonic markers 2.
  • Control over Diabetes type 2 and Hypertension: Glycine is an important amino acid for the functioning of the body and it is found to be very low in diabetic patients. Zhu et al., 2010 found that marine-origin collagen supplements may benefit glucose and lipid metabolism, insulin sensitivity, renal function, and hypertension management in Chinese patients with T2DM and hypertension 3. Therefore, taking these natural supplements, which are high in glycine, may help you manage your blood sugar levels and control the progression of diabetes.
  • Improved brain health: Apart from its role in managing blood sugar levels, glycine also controls the excitation of your brain cells along with sleep patterns. Glycine from the supplements helps you focus on your tasks and improves your sleeping pattern.
  • Weight management: Marine origin collagen is free of any carbs, sugars, and fats meaning that they do not lead to excess weight gain.

Different Forms of Marine-Origin Collagen Supplements

These products are extracted from fish skin and are available in different forms, making the whole supplement-taking process easier for you.

And if you really don’t want to consume this product but want the benefits of it, you can buy marine collagen creams and apply them to your skin. The options are endless.
