If you’re inspired by the potential benefits of collagen protein powder—like supporting skin, hair, gut, and joint health—you may be purely researching which collagen supplement to try out.

Before making an impulsive purchase (though I get it, who wouldn’t want those benefits?), ensure the product aligns with your dietary needs, preferences, and standards. After all, two things are certain: 

  1. We can’t stop the clock

Purely Inspired Collagen Peptides offer hydrolyzed collagen from grass-fed, pasture-raised bovine (cows) free from recombinant bovine growth hormone (rBGH). As a bonus, the collagen is enriched with biotin, vitamin C, zinc, and (allegedly) more B vitamins—more on this coming up.

Experience Using Purely Inspired Collagen Peptides

Lauren Strong, GGR senior staff writer and CPT, tested the Unflavored version of Purely Inspired Collagen Peptides, which might be a one-and-done for her: “Personally, I wouldn’t buy this again and may add cocoa powder to the container for some flavor.”

A person pours some Purely Inspired Collagen Peptides into a cup of coffee.

We might be on a rocky road, but let’s see if we pivot to a smoother path.

Price Per Serving

A 20-serving tub of Purely Inspired Collagen Peptides costs $24.99, equating to $1.25 per serving. An 18-pack of single-serve sachets costs $29.99, or $1.67 per serving.

To save on orders, Purely Inspired offers 30% off your first subscription and 15% off subsequent orders. Amazon Prime members can get a 20-serving tub for just $17.97, making it $0.90 per serving.

Looking at a cup of coffee with Purely Inspired Collagen Peptides mixed in.

Ultimately, we rate Purely Inspired a 3 out of 5 for price.

Formulation

A 20-gram serving of the Unflavored Collagen provides 70 calories, 20 grams of collagen, 18 grams of protein, and no carbs or fat. It also includes 250 milligrams of vitamin C1 (immune and collagen support), 11 milligrams of zinc2 (immune support), and 3,000 micrograms of biotin3 (hair, skin, and nail support).

The Vanilla flavor closely mirrors these nutritional values, with 80 calories, 0.5 grams of fat, and 1 gram of carbohydrates per serving. However, it includes biotin, but vitamin C and zinc are left behind. 

RELATED: Collagen Protein Vs Whey Protein

While we’ll primarily refer to the Unflavored variety below (since Vanilla is currently unavailable), we’ll still highlight it due to some notes listed below. Interpreting some details left me with question marks, resulting in a 3 out of 5 rating, but let’s try to understand its formulation better together.

Potential Benefits

  • High collagen content: Provides 20 grams of collagen from grass-fed bovine, exceeding the general daily recommendation of 2.5 to 15 grams.4
  • High-quality collagen source: Contains bovine collagen peptides from hormone-free, pasture-raised cows, and a 2021 review5 emphasizes peptides from bovine (and fish) are better absorbed. 
  • Rich in types I and III collagens: Provides types I and III collagen, two of the most important for human health. Type I collagen—making up over 90% of the collagen in the human body—is essential for skin, bones, teeth, tendons, ligaments, and organs. Type III collagen is commonly found in the skin, muscles, and blood vessels.5

Potential Risks and Drawbacks

  • High micronutrient content: Provides 280% of the daily value for vitamin C, which could lead to toxicities6 if not managed carefully. While zinc levels do not exceed 100% of the daily value, be mindful of additional sources to avoid excess intake. As for biotin, it’s not toxic at high levels, but you could save a buck or a few by skipping your current biotin supplement.3
  • Questionable ingredients list: Main Purely Inspired site lacks full transparency about its Unflavored formulation, yet Amazon lists “collagen peptides, silica, niacin, vitamins B6 and B12, biotin, calcium, and sodium” on its product page, making it difficult to understand the complete ingredient profile. In contrast, all ingredients are listed for the Vanilla flavor.
  • Uncertain B vitamin content: Mentions a B vitamin complex (insinuating a combination of multiple B vitamins) on the main website, but only biotin is listed on the label. Despite B vitamins—niacin and vitamins B6 and B12—listed on the Amazon page, the quantities in all formulations aren’t identified. 

Taste and Solubility 

Lauren tested the Unflavored option and remarked, “It’s unflavored, but it alters the taste of coffee and water in a slightly bitter, not-so-awesome way. It’s tolerable, though, so it gets 3 out of 5 stars from me.”

Lauren needed to break up a few floaters with her fork when mixing but imagined it would blend nicely in a water bottle. Initially, it appeared quite cloudy when mixed with water, but it eventually cleared up without any remaining sediment. Lauren found that Purely Inspired’s collagen powder mixed relatively well, giving it a 4 out of 5 for solubility.

Side Effects

Collagen supplements7 are generally considered safe, and Lauren experienced no adverse side effects while using Purely Inspired Collagen Peptides. She awarded it a perfect 5 out of 5 in this category.

Third-Party Testing

There is no indication on the product itself or purelyinspired.com of third-party testing, resulting in a 1 out of 5 rating in this category. 

That said, we conducted our own third-party testing by sending this supplement to Ellipse Analytics, which tested more than 150 protein powders for purity (heavy metals) and label accuracy (protein content). 

GGR-Protein-Data-Scorecard-purely-inspired-collagen
GGR collaborated with Ellipse Analytics, an accredited third-party lab, to test more than 150 protein powders. We screened for dozens of factors and rated each product against its peers. Excellent indicates the top 10% of products; Above Average is the top 25% of products; and Meets Standard is the top 50%.

Purely Inspired Collagen Peptides in Vanilla ranked as Meets Standard overall in our tests, which means that it passed our rigorous quality screen and ranked in the top half of all products we tested.

Purely Inspired Collagen Peptides vs Transparent Labs Collagen Hydrolysate

Transparent Labs Collagen Hydrolysate

Transparent Labs Grass-Fed Collagen Hydrolysate

GGR Score: 4.7 starstarstarstarstar

Product Highlights

  • No artificial sweetener, colors, or preservatives
  • Formulated with grass-fed bovine collagen peptides
  • Claimed to help eliminate visible signs of skin aging like sagging and wrinkles
  • Made with minimal ingredients

Pros & Cons

Pros

  • Worldwide shipping
  • A good amount of positive reviews
  • Easily mixable in cold or hot beverages

Cons

  • Only 10 g of protein per serving
  • Low doses of collagen compared to other brands
  • Doesn’t include vitamin C, which can help with absorption
  • Only comes in 1 flavor

Bottom Line

Transparent Labs Grass-Fed Collagen Hydrolysate is a collagen rich in type I and type III collagen peptides made without artificial sweetener, colors, or preservatives.

Transparent Labs Collagen Hydrolysate is another option containing bovine collagen, but it stands out from Purely Inspired in several key ways:

  • Serving size: Smaller based on grams, but both are one scoop.
  • Collagen content: Provides 10 grams less collagen per serving, though it’s comparable gram-for-gram.
  • Flavor options: Unflavored and Chocolate flavors are available, unlike Purely Inspired’s current lack of Chocolate and Vanilla flavors.
  • Third-party testing: Certified by Informed-Choice for purity and banned substance-free.
  • Cost: Lower based on serving size, costs almost double the price gram-for-gram of collagen.

The choice is yours, but you might favor Transparents Lab if you prefer a readily available chocolate flavor and value transparency. For a detailed comparison, please refer to the accompanying table and our Transparent Labs Collagen Hydrolysate Review.

Customer Experience 

Purely Inspired offers its customers positive perks, but certain factors might detract from their overall experience. Here’s what we mean:

  • Offers free shipping on orders over $30, which is lower than other retailers. However, their collagen products, except for the sachets, don’t meet this limit. 
  • Sells on third-party retailers like Amazon and Walmart, which provides flexibility and often same-day or next-day delivery, but you’re subject to their policies.
  • Comes with a 30-day return policy, although the product must be unopened and returned at the customer’s expense.
  • Provides a contact form for customer service inquiries, but no direct phone number, chatbot, or email address.
  • Offers 30% off your first subscription and order; subsequent orders are 15% off. 

Of course, these are all subject to the individual’s preference, but they are worth noting.

Ordering Purely Inspired Collagen Peptides

Ordering Pure Inspired Collagen Peptides is as simple as adding it to your cart, filling in payment and shipping information, and checking out. You won’t need to create an account for a one-time purchase, but one is required for subscription orders to make modifications.

Customer Reviews

Most customers enjoy Purely Inspired Collagen Peptides, as evidenced by its 4.3 out of 5-star rating on Amazon from nearly 10,000 reviews. It’s favored for its value and ease of mixing into morning coffee, smoothies, and protein shakes. Many users also report skin, hair, and nail improvements and reduced joint pain. However, there are mixed opinions on its texture and solubility.

Final Verdict of Our Purely Inspired Collagen Peptides Review

Purely Inspired offers a bioavailable hydrolyzed powder from grass-fed bovine, making it a great source of types I and III collagen. Here are our final takeaways to consider before purchasing: 

  • Evidence-based collagen dose: Delivers 20 grams of collagen per serving, surpassing the general daily recommendation of 2.5 to 15 grams.4
  • Limited flavor options: Currently, only an unflavored option is available on the product site, and it doesn’t provide a complete ingredient list. The availability of Vanilla and Chocolate flavors is uncertain.
  • Questionable vitamin B complex: Claims to offer a B vitamin complex, but apart from biotin, no other B vitamins are identified or quantified.
  • Additional nutrient support: Includes vitamin C, zinc, and biotin for added collagen and immune support.
  • Potential vitamin C overload: Contains high concentrations of vitamin C, posing toxicity risk.
  • Transparency and testing: Lacks full transparency and third-party testing.
