The basics
What Is Skinny Collagen?
Skinny Collagen is a collagen peptide powder from Simple Promise™, the Camas, Washington, company behind CardioClear7, HeartAide and TriBlock7. The jar calls it a Daily Fat-Burning Beauty Blend.* Instead of a single collagen source, it blends four, which together provide collagen types I, II, III, V and X.
The idea is to combine two goals many women over 40 care about in one simple scoop: looking and feeling your best (skin, hair, nails and joints) and staying on track with healthy weight management. Because it is unflavored, you can stir it into your morning coffee, water, juice or a smoothie without changing the taste.

Skinny Collagen Ingredients: The Actual Supplement Facts Label
Here is the Skinny Collagen Supplement Facts panel, retyped so it is easy to read. Many review sites skip it entirely.
Supplement Facts
Serving Size: 1 Scoop (5.6 g) Servings Per Container: 30
** Percent Daily Value based on a 2,000-calorie diet. † Daily Value not established.
Other ingredients: silica.
Contains: egg and fish (cod).
What the label tells you
A clean, short label. Just collagen, two support ingredients and silica to keep the powder flowing.
5 g of collagen per scoop, a common daily amount for collagen peptide powders.
Four sources, five types. The amount from each source is not listed separately, which is typical for blends.
Allergen note: it contains egg and fish (cod), so it is not for people with those allergies.
Good to know: although some marketing badges say “vegan-friendly,” every collagen source here is animal-based, so it is not vegan or vegetarian.
Ingredient by ingredient
Each Skinny Collagen Ingredient Explained
Here is what each ingredient is known for and what the research says, in plain English.
The collagen blend
5 g
Skin & structure
Bovine Collagen · in 5 g blend
Collagen from cows is rich in types I and III, the main collagen types in skin, bones and blood vessels. Hydrolyzed bovine collagen is one of the most common forms used in skin studies.*
Main skin collagen typesSkin hydration
Marine Collagen · in 5 g blend
Marine collagen comes from fish (here, cod) and provides type I collagen. Its small peptides are popular in beauty supplements for skin firmness and hydration.*
Type I collagenJoint comfort
Chicken Collagen · in 5 g blend
Chicken collagen is a traditional source of type II collagen, the main collagen in cartilage, the cushion that protects your joints.*
Type II collagenHair & body structure
Egg (Eggshell) Collagen · in 5 g blend
Collagen from eggshell membrane adds types V and X, according to Simple Promise. Type V works alongside type I in skin and hair, and type X is found in growing bone and cartilage.*
Types V & X
Digestion & gut support
225 mg
Gut balance
TriBiome™ · 200 mg
TriBiome™ is a branded gut-support ingredient listed on the label as triacetin. Simple Promise describes it as supporting gut balance, digestion and appetite control. There are no published studies on TriBiome™ in this formula that we could find.*
Branded ingredientProtein digestion
Pepzyme AG™ · 25 mg
Pepzyme AG™ is a branded digestive enzyme blend. Enzymes like these help break protein down into smaller pieces, which is why they are often paired with collagen and protein powders.*
Enzyme blend

Step 1 · Collagen building blocks
Hydrolyzed collagen is broken into small peptides, which are easier for your body to absorb. Harvard’s Nutrition Source notes that these shorter chains are believed to be absorbed more effectively than whole collagen.*
Step 2 · Digestion support
The Pepzyme AG™ enzyme blend helps break protein down, while TriBiome™ is included for gut balance and comfortable digestion.*
Step 3 · Protein that helps you feel satisfied
Collagen is a protein. Adding protein to a drink or meal can help you feel fuller, which is why many people use collagen as part of a healthy weight-management routine.*

What to expect
Does Skinny Collagen Work?
For skin, the research on hydrolyzed collagen is genuinely encouraging. A 2021 meta-analysis in the International Journal of Dermatology pooled 19 studies with 1,125 people (mostly women aged 20 to 70). Taking hydrolyzed collagen for about 90 days improved skin hydration and elasticity and reduced wrinkles compared with placebo. Harvard’s Nutrition Source adds that some trials have also found improvements in joint mobility and joint discomfort.*
For weight management, the evidence is more limited. Simple Promise states that its weight-related figures come from studies of individual ingredients, not the finished Skinny Collagen formula. The practical benefit is simple: collagen adds protein to your day, and protein can help you feel satisfied.*
To be fair to readers, Harvard also notes that much collagen research is funded by industry, so independent studies are still needed.
How long does Skinny Collagen take to work?
Weeks 1–2 · Building the habit
One scoop a day becomes part of your morning drink. Some people notice they feel more satisfied between meals.
Weeks 4–8 · Settling in
This is when people often start noticing changes in nails and how their skin feels.*
About 3 months · Skin results
The skin studies ran for about 90 days, so give it a full three months for a fair test.*
Individual results vary. These are general patterns, not guaranteed outcomes.
Here are the current prices for the unflavored version on the official Simple Promise store. Each package is a one-time purchase, ships free in the U.S. and is covered by the same 365-day money-back guarantee. The regular price is listed at $99 a jar.
Because the skin research ran for about 90 days, the 3-jar package is the natural starting point: it covers three months at $49 a jar. The 6-jar package is the best value at $33 a jar, about $1.10 a day. If you just want to see how you like mixing it into your drinks, one jar is a fine start, and the 365-day guarantee covers every package. Prices can change, so the order page always shows today’s price.
Simple Promise backs every Skinny Collagen order with a 365-day money-back guarantee: if you are not 100% satisfied at any time within those 365 days, you can return it for a full refund. Customer support is at 1-800-259-9522 or support@mysimplepromise.com.

If you search for Skinny Collagen, you may find pages such as skinny-collagen.us that call themselves the “USA Official Website.” The actual maker and seller is Simple Promise, at mysimplepromise.com. Look-alike pages are often affiliate sites, and some make claims such as “FDA approved,” which never applies to dietary supplements.
Check the checkout page shows Simple Promise and the 365-day guarantee.
Compare prices: $59, $147 and $198 are the official unflavored package prices we verified.
Be wary of claims like “works like GLP-1” or guaranteed weight loss.

Buying tips
Where to Buy Skinny Collagen: Official Site or Amazon?
Simple Promise sells Skinny Collagen through its official website and also lists it on Amazon. For most buyers, the official website is the better choice for the 3- and 6-jar package prices, free U.S. shipping and the full 365-day money-back guarantee directly from the maker. Skinny Collagen is not sold in Walmart, Target, CVS or Walgreens stores.
Skinny Collagen is a multi-collagen peptide powder from Simple Promise. One scoop gives you 5 g of hydrolyzed collagen from four sources (bovine, marine, egg and chicken), plus 200 mg of TriBiome™ and 25 mg of the Pepzyme AG™ enzyme blend. It is designed to support skin, hair, nails, joints, digestion and healthy weight management.*
What are the Skinny Collagen ingredients?

What types of collagen are in Skinny Collagen?
Simple Promise says the blend provides five collagen types: type I (bovine and marine), type II (chicken), type III (bovine), and types V and X (eggshell).
How do I take Skinny Collagen?
Mix one scoop into a glass of water, juice, a smoothie or your favorite drink, once a day. The maker suggests taking it 20 to 30 minutes before a meal if you are using it for weight management.
How long does one jar last?
Each jar holds 30 scoops, so one jar lasts a month at one scoop a day.
What does Skinny Collagen taste like?
The unflavored version is designed to mix into any drink without changing the taste. The official store has also offered a Strawberry Margarita flavor.
How much does Skinny Collagen cost?
On the official Simple Promise store, one jar is $59, three jars are $147 ($49 a jar) and six jars are $198 ($33 a jar). That works out to about $1.10 to $1.97 a day. The regular price is listed at $99 a jar. Prices can change, so check the order page for today’s price.
Is there a money-back guarantee?
Yes. Skinny Collagen is covered by Simple Promise’s 365-day money-back guarantee.
Does Skinny Collagen help with weight loss?
Collagen is a protein, and protein can help you feel full. Simple Promise says its weight-management figures come from studies of individual ingredients, not the finished formula. The best-supported collagen benefit in research is for skin elasticity and hydration. Think of Skinny Collagen as a helpful part of a healthy routine, not a stand-alone weight-loss product.*
Does Skinny Collagen work for skin?
A 2021 meta-analysis of 19 studies with 1,125 people found that taking hydrolyzed collagen for about 90 days improved skin hydration and elasticity and reduced wrinkles compared with placebo. Results vary by product and person.*
Is Skinny Collagen vegan?
No. Although some marketing badges describe it as vegan-friendly, the collagen comes from cows, fish, eggs and chickens, so it is not suitable for vegans or vegetarians.
Who should not take Skinny Collagen?
Anyone allergic to fish or eggs should avoid it, since the label says it contains egg and fish (cod). People who avoid beef or chicken for dietary or religious reasons should also note the bovine and chicken sources. If you are pregnant, nursing or managing a medical condition, ask your doctor first.
Are there Skinny Collagen side effects?
Collagen peptides are generally well tolerated. A few people notice mild fullness or stomach upset. The main issue to watch is allergy to fish or eggs.
Is Skinny Collagen sold on Amazon?
Yes, Simple Promise lists Skinny Collagen on Amazon. The official website is the place for the 3- and 6-jar package prices, free U.S. shipping and the 365-day guarantee directly from the maker.
Can men take Skinny Collagen?
Yes. Although it is marketed mainly to women, collagen peptides are suitable for adult men too.
Is skinny-collagen.us the official website?
No. The official seller is Simple Promise at mysimplepromise.com. Other sites using the product name may be affiliate pages, and some make claims such as “FDA approved” that do not apply to supplements.
The bottom line
Final Verdict: Should You Try Skinny Collagen?
Skinny Collagen makes multi-collagen simple. One unflavored scoop brings 5 g of hydrolyzed collagen from four sources, five collagen types, an enzyme blend and a gut-support ingredient together in any drink you like, with no sugar and no caffeine.*
