Powdered collagen, collagen shots, and collagen waters have exploded in popularity over the last few years. You've probably heard all about how collagen supplements [1]can help promote hair growth, improve joint health, and prevent skin from aging. Even Jennifer Aniston swears by it [2].

Admittedly, I'm a convert, too. I use the Vital Proteins Unflavored Collagen Peptides [3] ($19, originally $27) almost daily (it's Aniston's brand of choice, too), and it's currently on sale for a fraction of the price for Amazon's Big Spring Sale [4]. (It's one of many hot deals for under $25 [5], FYI.) I love the collagen powder for its ability to add a hearty dose of protein to anything I'm eating or drinking — it transforms a black coffee or low-protein veggie soup into something that's more satiating and protein-packed [6].

Each two-scoop serving is just 70 calories and has 18 grams of protein and 20 grams of collagen peptides. This powder is also flavorless, so I can add it to pretty much anything and can't taste it. Depending on how much protein I need, I add one or two scoops to coffee, soups, pasta sauces [7], oatmeal, or smoothies. Although Vital Proteins claims this powder can be mixed into hot and cold liquids, I find it blends easier in warm temps, which is why I often add it to hot veggie soup or warmed pasta sauce. Sometimes I'll add a scoop to a cup of hot herbal tea.

Vital Proteins Collagen Peptides Pros and Cons

Pros

• Flavorless, making it easy to mix into foods or drinks

• Packs 20 grams of protein per serving

Cons

• Doesn't dissolve well in cold or room-temperature liquids

• Not vegan-friendly

Vital Proteins Unflavored Collagen Peptides also come in stick packs [8] ($30, originally $39), so I love taking a few with me when I travel. That way, if the breakfast situation in my hotel or Airbnb isn't ideal, I at least know I can add a boost to my morning coffee.

There's no better time to stock up on the Vital Proteins Collagen Peptides Powder than right now, since it's on sale. You can also shop the other Vital Proteins supplements at discounted prices, like the Marine Collagen Peptides Powder Supplement [9] ($29, originally $39) or the Vital Performance Protein Powder [10] ($30, originally $35).
