Clean Nutra Shelf Builder is a women's creatine monohydrate powder sold by Clean Nutraceuticals, and its maker says it is an all-in-one scoop for strength, lean tone, recovery and beauty. The product page lists 5 g of creatine monohydrate per scoop, plus added ingredients the seller counts as 15 science-backed nutrients in one scoop, including collagen, biotin, zinc and vitamin D3. As of October 28, 2026, the seller lists $39.95 for one 30-day bottle, $69.95 for three bottles and $99.95 for five bottles, and offers a 30-day money-back guarantee on returns that excludes shipping. The NIH Office of Dietary Supplements reports that numerous clinical trials on creatine generally show a benefit for high-intensity, intermittent activity, and this page keeps that creatine research separate from the seller's claims about the blend. Below you will find the ingredient list, price and subscription terms, refund steps, side effects, who should check with a clinician first, and how this product compares with plain creatine.

What is Clean Nutra Shelf Builder, and who is it for?
Shelf Builder is a creatine powder the seller calls ‘engineered for women.' The seller says it is made to fuel strength and sculpt lean curves ‘without the bloat or bulk of traditional powders.' The package front reads ‘Women's Creatine Monohydrate Powder' with added BCAAs, collagen, myo-inositol and L-glutamine. The seller's privacy policy says its products are intended for adults.
What does the seller say it does, and how is it supposed to work?
The seller markets the product for six areas: strength and lean tone, beauty and skin support, gut and digestion, daily energy, hormonal balance and faster recovery. The product page calls creatine ‘the most studied form of creatine for strength, power and lean muscle support.'
For how creatine works in general, the Cleveland Clinic says most creatine goes to skeletal muscles, where it helps make ATP, a source of energy your cells use when you exercise. Its Cleveland Clinic creatine page says creatine helps maintain a steady energy supply to muscles during intense lifting or exercise.
The seller also shows a timeline, from ‘Week 1′ through '12 months,' describing what women may feel with daily use. Those timeline entries are the seller's own expectations, not study results.
What's in each scoop?
The seller lists 5 g (5,000 mg) of creatine monohydrate per scoop. Amounts for the other ingredients are on the Supplement Facts panel on the bottle, so read that panel for each dose. The table keeps creatine separate from the added ingredients.
| Ingredient | Amount as labeled | What the seller says it is for |
|---|---|---|
| Creatine monohydrate | 5 g (5,000 mg) per scoop | Strength and lean tone |
| Collagen peptides | Supplement Facts panel | Skin, hair and nails |
| Biotin | Supplement Facts panel | Hair, skin and nail support |
| Zinc | 11 mg | Immune defense, skin repair and hormone production |
| L-Glutamine | Supplement Facts panel | Muscle recovery and gut lining |
| Digestive enzyme and probiotic | Supplement Facts panel | Digestion and nutrient absorption |
| Maca root extract | Supplement Facts panel | Energy and balance (the seller says it is traditionally used this way) |
| Myo-inositol and D-chiro inositol | Supplement Facts panel | Cycle regularity, insulin sensitivity and hormonal balance |
| Hyaluronic acid, vitamin D3 and iron | Supplement Facts panel | Hydration, bone and energy support |
The front of the package also names BCAAs and folate. The bottle's Supplement Facts panel gives the amount of each.
Caffeine: To confirm whether there is caffeine, read the Supplement Facts panel on the bottle, or email support@cleannutra.com before you order.
Servings: The number of scoops per bottle is on the Supplement Facts panel. The net weight is 9.46 oz (265 g).
Flavor: Tropical orange.
Does creatine work? What the research says
The research below is about creatine itself. For a deeper look at the human studies, see Creatine Benefits: Human Studies, Side Effects and Safety (our research library).
High-intensity, short-burst work
The NIH Office of Dietary Supplements, in its exercise and athletic performance fact sheet, says numerous clinical trials generally show a benefit for high-intensity, intermittent activity, with potential variation in individual responses. It says creatine may increase strength, power and work from maximal effort muscle contractions, and that over time it helps the body adapt to athlete-training regimens.
Endurance sports
The same NIH fact sheet says creatine is of little value for endurance sports. The Cleveland Clinic says creatine improves performance in short, high-intensity exercise such as weightlifting, sprinting and bicycling, without affecting your ability to exercise for longer periods.
Muscle gain
The Cleveland Clinic says studies show that regularly taking creatine with weightlifting and exercise can help increase muscle growth in people 18 to 30 years old. It says some studies show people taking creatine may gain an extra two to four pounds of muscle over four to 12 weeks of regular exercise. It also says there is not enough research to say creatine helps muscle growth in people older than 65.
Safety research
The ISSN's 2021 common-questions paper concludes that at recommended dosages, creatine does not result in kidney damage or renal dysfunction in healthy individuals. It says a loading phase is not required.
Women
The 2021 ISSN paper says there is accumulating evidence that creatine supplementation has the potential to be a multifactorial intervention across the lifespan in females, with little to no side effects. The same paper says the current body of evidence does not indicate that creatine increases total testosterone, free testosterone or DHT or causes hair loss, and notes that the hair-loss speculation stems mainly from a single study of college-aged male rugby players.
The 2021 paper also discloses that several authors report funding from, or advisory roles with, companies that make or sell creatine, including AlzChem. Its lead author is CEO of the ISSN, which receives industry sponsorship. Weigh that alongside its findings.
How much creatine should you take, and when?
The seller says to take ‘one clean scoop a day.' The product page asks ‘How and when should I take it?' in its FAQ, so check the label directions for timing.
The NIH fact sheet lists a loading dose of 20 g a day for up to 7 days and 3 to 5 g a day for up to 12 weeks as typical use. The ISSN 2021 paper says loading is not required. A 5 g scoop a day therefore sits at the top of the NIH's 3 to 5 g range (our comparison, not a dosing recommendation). If side effects develop, the Cleveland Clinic suggests dividing the daily amount into smaller doses taken through the day.
One buyer review on the product page says the powder ‘mixes well with either water or milk.'

What are the side effects, and is it safe?
The NIH says creatine has few safety concerns reported at typical doses. The table lists what the sources report.
| Effect | What the source says |
|---|---|
| Water weight gain | NIH lists weight gain due to water retention. The ISSN 2021 paper says creatine may increase water retention over the short term, but creatine does not always lead to water retention. |
| Nausea, diarrhea, muscle cramps, muscle stiffness, heat intolerance | NIH lists these as anecdotal reports. |
| Kidney effects | The ISSN 2021 paper says that at recommended dosages, creatine does not result in kidney damage in healthy individuals. |
| Hair loss and hormones | The ISSN 2021 paper says the current body of evidence does not indicate creatine causes hair loss or raises total testosterone, free testosterone or DHT. |
The Cleveland Clinic says creatine supplements are safe for most people to take, but advises talking to a healthcare provider first. For reporting, FDA says anyone may report a suspected supplement adverse event through the Safety Reporting Portal (safetyreporting.hhs.gov), as described on the FDA questions and answers on dietary supplements page.
The research above covers creatine. For the other ingredients in the blend, ask your clinician or pharmacist if you have questions.
Who should not use it, and who should ask a clinician first?
The Cleveland Clinic says a provider will likely ask whether you have diabetes, kidney disease or liver disease, and whether you take medications, vitamins or other supplements. It advises talking to a provider before taking creatine, regardless of fitness level, age or health.
The seller's label says to ‘consult your healthcare provider before beginning any supplement, especially if you are pregnant, nursing, have a medical condition, or take medications.'
The ISSN 2021 paper says that based on limited evidence, creatine appears safe and potentially beneficial for children and adolescents. It also describes a growing body of evidence showing musculoskeletal and performance benefits in older adults when creatine is combined with exercise.
Is Clean Nutra Shelf Builder a scam, or is it legit?
You can check most of the basics yourself. The seller's pages show the following.
- Seller: Allseason Enterprises, LLC, doing business as Clean Nutraceuticals, lists a Las Vegas, Nevada address on its contact and refund pages.
- Contact: support@cleannutra.com, and (866) 221-7374 on the refund page.
- Where it is sold: The seller's site and Amazon Subscribe & Save. The privacy policy also names Amazon, TikTok Shop and Walmart as marketplaces where the products are sold. Check that marketplace's return rules before buying there.
- Payment: The FAQ says PayPal is available if you prefer not to share card details. The privacy policy says payments are processed by Shopify Payments and other PCI-compliant processors.
- Refund terms: The product page, refund policy and Terms of Service say 30 days, but the seller's FAQ says 180 days. Get the window confirmed in writing from support@cleannutra.com before buying, and plan around the 30-day terms in the refund policy.
- Regulatory note: The seller's pages say ‘These statements have not been evaluated by the Food and Drug Administration.' FDA says it does not have the authority to approve dietary supplements before they are marketed.
What you cannot confirm from the pages: The ‘680+ peer-reviewed clinical trials on creatine' figure refers to creatine research in general.
The privacy policy says the site shares device and shopping information with many advertising partners, and that health-related information is handled as sensitive. Read that policy if this matters to you.
Protect yourself: Keep your order confirmation, use the 30-day window, and ask support for the lab's name and a copy of its report before you buy.
How does it compare with plain creatine and other options?
The options below cover different needs, so none is ranked here.
| Option | What it is | What the research covers |
|---|---|---|
| Clean Nutra Shelf Builder | Creatine monohydrate (5 g per scoop) plus added vitamins, minerals and other ingredients | Creatine studies apply to the creatine. |
| Creatine monohydrate on its own | The form the ISSN 2021 paper calls the optimal choice, the most studied form | NIH lists 3 to 5 g a day as typical use. You set the dose yourself. |
| Other creatine forms | Forms such as those more soluble in fluid | The Cleveland Clinic says other forms of creatine do not appear to have the same benefits. |
| Regular exercise and sleep habits | No supplement | NHS says regular exercise makes you feel less tired in the long run, and Cleveland Clinic calls regular exercise crucial for a healthy lifestyle. |

Short answers to other questions readers ask
Why am I always so tired even though I sleep a lot?
MedlinePlus lists causes of fatigue including sleep apnea and other sleep disorders, anemia, thyroid disease, depression and anxiety, and certain medicines. The MedlinePlus fatigue page says fatigue can be a symptom of many conditions. Fibromyalgia is another cause, and people with it often say no matter how long they sleep, it is never restful. Penn State Health describes three main categories: lifestyle and stress, nutrition, and underlying health reasons. Bring this pattern to your clinician.
Why am I always tired and have no energy?
The same causes apply. The NHS says many cases of tiredness are due to stress, not enough sleep, poor diet and other lifestyle factors. Its self-help tips for tiredness include regular meals, regular sleep times and cutting back on caffeine and alcohol before bed.
What are warning signs of fatigue?
MedlinePlus says to contact your provider if you have been feeling tired for weeks. The NHS says fatigue that rest and sleep do not relieve may point to an underlying condition. The Cleveland Clinic fatigue guide lists fatigue along with chest pain or shortness of breath, an unusually fast or slow heartbeat, a pounding or irregular heartbeat, headache or vision problems, muscle weakness, or thoughts of harming yourself or others as reasons to seek immediate medical attention.
What am I lacking if I am always tired?
The Cleveland Clinic says a provider should help rule out infections, disease, illness, vitamin deficiencies and other health conditions. A clinician can work out which, if any, applies to you.
What drink helps with fatigue?
The NHS says that if you are mildly dehydrated, a glass of water can help. It also says caffeine in coffee, tea, fizzy drinks and energy drinks can disrupt sleep rhythms and lead to daytime tiredness. Ask your clinician if tiredness continues.
At what age are you most tired?
To see whether your tiredness follows an age-related pattern, keep a short log of when it happens and bring it to your clinician.
