Superfoods that can be worth the splurge

Spending money on foods for fuel can be worth the splurge.

Superfoods like E3Live blue-green algae, which is said to stabilize hormones with dozens of vitamins and minerals, skin hydrating collagen, Manuka honey and more can cost a lot but potentially pay off health-wise in the long run.

Foods marketed as superfoods are rich in nutrients and are typically plant-based and boast a number of health benefits. And Americans are willing to invest in food products that have added health benefits. Last year, young adults opted for foods and drinks with healthy nutritional profiles for 19 percent of their meals and in-between snacks, according to market research firm NPD Group.

"There are a variety of superfoods, like kale, quinoa and acai berry, that have mainstreamed and found their way into a myriad of foods," Darren Seifer, NPD's food and beverage industry analyst said in a statement. "Rather than being one of many offering a superfood, understanding the trajectory of emerging superfoods helps food marketers be ahead of the curve in making calculated decisions about new product investments."

Here are the costs and benefits of each:

Collagen powder

Drinking collagen has been touted as the natural alternative to lip injections and fillers to promote glowing and radiant skin as a fountain of youth of sorts praised by the likes of the Kardashians and Jenifer Aniston. Collagen, a fibrous protein, is typically derived from animals like chickens or fish scales and contains high amounts of amino acids that are crucial to repairing tissues and joint surfaces to support skin and hair.

Dozens of collagen powders are on the market and contain ingredients like “hydrolyzed” type-I collagen extracted that can be dissolved into liquids. The protein-packed collagen powder is said to combat thinning hair, chronic digestive problems and lighten and brighten skin. A review from the Journal of Cosmetic Dermatology found that subbing in collagen peptides significantly increased hydration in skin after eight weeks and ramped up collagen density.
