Collagen is a protein that ladies are very looking for. The reason is absolutely due to its beauty benefits. Not only to hydrate the skin, but collagen also has more positive points to our bodies, like relieving osteoarthritis and lowering blood pressure and blood sugar levels. Basically, collagen is naturally produced in your body. However, it also needs support from your daily intake to make its performance the best. These foods could increase collagen in your body.

Bone broth

I still remember that one day, my female work partner requested ‘beauty broth’ for her lunch. Lately, I knew what she meant was soup containing bone broth. Although we still don’t have research that proves bone broth is a source of collagen, this option is by far the most popular by word of mouth. 

Bone broth is made of bones and connective tissue. It contains calcium, magnesium, phosphorus, collagen, glucosamine, chondroitin, amino acids, and many other nutrients.

Fish

Like other animals, fish have bones and ligaments made of collagen, making them a natural source of the skin-plumping substance. Per a study in the journal Food and Nutrition Sciences, fish collagen may even be preferable to collagen found in protein-packed meats such as beef or pork.

According to the research, fish collagen is absorbed up to 1.5 times more efficiently into the body when compared to bovine or porcine sources of collagen. Due to the fact that fish collagen is absorbed more efficiently (and therefore enters the bloodstream at a quicker rate), it is considered to be one of the best sources of collagen.

Spirulina

As White notes, more than 60 percent of spirulina consists of amino acids: the building blocks of collagen. Therefore, the blue-green microalgae found in both fresh and oceans is an excellent source of the stuff. A 2017 study in the journal Pharmaceutical Biology found that when spirulina was incorporated into topical skin creams, it improved cell viability and aided wound healing.

Like certain types of meat, spirulina is a great source of protein. In fact, one tablespoon of powdered spirulina yields 6 grams of muscle-building nutrient.

Berries

Though citrus tends to get all the glory for its vitamin C content, berries are another excellent source. Ounce-for-ounce, strawberries actually provide more vitamin C than oranges. Raspberries, blueberries, and blackberries offer a hefty dose, too. Berries are high in antioxidants, which protect the skin from damage.

Leafy greens

Thanks to Popeye for teaching us how to love eating spinach. We all know leafy greens are a key player in a healthy diet. As it turns out, they may offer aesthetic benefits, too. Spinach, kale, Swiss chard, and other salad greens get their color from chlorophyll, known for its antioxidant properties. Some studies have shown that consuming chlorophyll increases the precursor to collagen in the skin.
