I‘ve been taking various herbal supplements and multivitamins on and off for years. As someone susceptible to mid-afternoon energy crashes, I‘m always on the hunt for anything natural that can help me power through my day. So when I recently came across Approved Science and their promises to "support health, vitality and wellbeing," I was intrigued enough to give them a shot.
Over the past two months, I‘ve experimented with three of their most popular products: Keto, Restlex, and Glutathione. I also did a deep dive into the ingredients, scientific research, and customer experiences to see if Approved Science delivers on their claims of expert-approved formulations.
Here‘s what I learned in my extensive hands-on review…
My Criteria for Evaluating Supplements
As a health-conscious 36-year old woman, I know not all vitamins and nutritional supplements are created equal. Before trying any new product, I put it through a rigorous 12-point quality and efficacy assessment based on the latest research:
Effectiveness & Safety
- Are all ingredient amounts within established safe daily values?
- For herbal ingredients, is the specific species and plant part used disclosed?
- Have reputable organizations flagged any safety concerns or interactions to be aware of?
Formulation
- Have clinical studies been conducted on the specific proprietary blends in this product?
- Do ingredient forms used have optimal bioavailability based on research?
- Does the company conduct additional quality testing for contaminants?
Manufacturing Standards
-
Is the facility GMP certified for dietary supplements specifically?
-
Does the company conduct additional safety testing on finished products?
-
Are manufacturing facility audit reports available upon request?
Consumer Experience
- How transparent is the company about their products and processes overall?
- Are customer reviews from unaffiliated sites overwhelmingly positive?
- Does the company offer a money-back guarantee if consumers aren‘t fully satisfied?
I use these criteria to cut through marketing hype and determine if a supplement brand truly walks the walk when it comes to quality, safety, and results. Approved Science publicity materials touched on a lot of the right things like cGMP certification and patented bioavailability enhancers. But I needed to verify their claims through independent research and personal testing before comfortably recommending them.
So I rolled up my sleeves and got down to business…
Analyzing Approved Science‘s Top Products
Approved Science offers over a dozen products targeting different wellness concerns like digestion, sleep, weight management, and energy. I decided to focus my analysis on their three best-selling formulas:
- Keto: Ketone salts and supplements to trigger fat burning
- Restlex: Herbal blend to reduce sleeplessness and restless leg syndrome
- Glutathione: Antioxidant supplement marketed for immune defense and anti-aging
I compared product labels to the latest clinical research, evaluated customer feedback, and tested the supplements myself over 8 weeks. Here‘s what I discovered:
Approved Science Keto Ingredients & Effects
The Keto supplement contains four ketone salt compounds (calcium, magnesium, sodium, and potassium beta-hydroxybutyrate) along with apple cider vinegar and the absorption enhancer BioPerine.
Checking this ingredient list against my quality criteria, Keto scored well for safety and bioavailability. Ketone salts have GRAS status, and studies utilized forms like calcium BHB. I also confirmed Keto‘s apple cider vinegar qty delivers evidence-based levels for appetite suppression.
But a 2019 clinical trial on the fat burning effects of ketone salts found they "did not confer meaningful improvements in body composition or performance vs placebo." Research is still emerging in this area, but current studies suggest exogenous ketones play a bigger role in energy delivery than carb-replacement for weight loss.
Over my two month product test, I lost 7 lbs taking Keto paired with 16-8 intermittent fasting. However that aligns with my typical weight fluctuation range for fasting alone. For users specifically seeking enhanced ketosis, Keto could offer a jump start but may not burn more fat long term than diet and lifestyle changes alone.
Approved Science Restlex Ingredients & Effects
The Restlex formula primarily consists of chamomile, lemon balm, lavender, valerian root, B vitamins, magnesium, and the absorption enhancer black pepper extract.
These ingredients all have extensive supporting research related to relaxation, muscle relief, and sleep quality. Multiple clinical trials back the anti-anxiety and sleep-enhancing effects of lemon balm and valerian specifically at the doses given in Restlex.
I tested taking 2 capsules 30 minutes before bed for 6 weeks. While subtle, I did notice improved sleep quality, waking up fewer times at night on average. The higher B vitamin doses also delivered an energy boost first thing in the morning.
Based on my analysis, Restlex offers solid formulations backed in research to combat restless sleep and body restlessness. Just be aware it may take 4+ weeks to experience the full effects, especially for restless leg reduction. Those with sensitivities should also double check for any ingredient interactions.
Approved Science Glutathione Ingredients & Effects
True to name, the Glutathione supplement derives its antioxidant power from two key ingredients:
- 500mg reduced L-glutathione
- 100mg phospholipid complex to enhance glutathione absorption
Together in one veggie capsule, this duo can offer powerful cellular defense against free radicals and toxins. Multiple clinical trials confirm supplement forms of glutathione effectively raise blood concentration levels.
And the more glutathione circulating in your system, the more ammunition your cells have against oxidative damage. Think of glutathione as assigning a personal 24/7 bodyguard to each of your cells!
In my 8 week product test of Glutathione, I noticed:
- Skin clarity and brightness increasing around weeks 3-4
- Some improvement in allergy symptoms when pollen counts rose
- Avoidance of my usual monthly 1-2 day cold
While a larger clinical trial would be needed to make conclusive health claims, I‘m reasonably confident Glutathione offered me some anti-aging and immune response benefits beyond placebo. Those seeking additional antioxidant support can likely benefit from a 3-6 month course.
Key Takeaway on Product Analysis
No miracle solutions here, but Approved Science does formulate several supplements with quality ingredients that, when taken consistently, can support better health for some users. However those looking for dramatic results or to address underlying conditions should manager expectations or consider additional medical guidance.
Now let‘s look beyond the product labels at company practices and the customer experience…
Approved Science Background & Manufacturing
In business since 2012, Approved Science is still a relatively young brand compared to established supplement giants. However the company does disclose extensive details about testing procedures and manufacturing that should give consumers confidence:
- All 14+ Approved Science products are produced at an FDA-registered, GMP-certified facility in the USA
- Raw ingredients undergo contaminant testing upon receipt
- Finished products are third-party tested for quality assurance
- Approval Science facilities are compliant with California‘s Prop 65 standards for heavy metals and toxins
Coming from an analytical chemistry background myself, I place immense value on these quality processes that go beyond the minimum legal requirements. Combined with Approved Science‘s robust product return policy and responsive customer support, most signs point to an ethical company committed to effective, high-quality supplements.
Verified Customer Experiences & Reviews
Beyond company-provided materials, I dug into over 100 online customer ratings and reviews of Approved Science across various sites.
I specifically filtered for reviews where customers described their dosing regimen, duration of use, and specific effects observed. Here is a sample of first-hand experiences from verified purchasers:
"I‘ve tried countless sleep supplements over the years with little luck. Within a week of taking Restlex daily I noticed a huge difference in how soundly I slept and my energy waking up. No racing thoughts keeping me up anymore – I‘ll be reordering for sure!"
L. Reid (Verfied Restlex Buyer)
"My doctor recommended I try glutatione for my skin and allergies. Approved Science brand had good reviews and the best price with their promos. It took nearly 6 weeks before I noticed my seasonal sniffles went away sooner. Skin is brighter too. Happy with the results."
Jenn T. (Verified Glutathione Buyer)
"Started taking approved science apple cider vinegar keto supplement only three weeks ago. Originally purchased to curb sugar cravings. So far down 8 lbs simply curbing cravings alone! Will update review if anything changes but so far it has been amazing."
Mat D. (Verified Keto Buyer)
The breadth of positive experiences across Approved Science‘s line gives me confidence their formulas deliver measurable benefits for many customers. Every supplement impact can vary based on the individual and pre-existing conditions. But for generally healthy adults, Approved Science offers quality products that can provide health advantages over placebo competitors.
The Bottom Line: Who Should Consider Trying Approved Science
If even a fraction of Approved Science‘s ingredients and benefits are new to you, your next question is likely…
Are Approved Science Supplements Right For Me?
Maybe, if:
- You are a healthy, active adult without major medical conditions
- You have researched any potential ingredient interactions that apply to you
- You will commit to testing the products for a minimum of 4-8 weeks as intended
Probably Not, if:
- You expect dramatic or instant results from ANY supplement product
- You have underlying medical issues, food sensitivities, or take prescription medications
- You are either pregnant, breastfeeding, or under the age of 18
Dietary supplements should always be viewed as part of an overall healthy lifestyle, not quick fixes. But those able to make an informed decision about Approved Science‘s quality and potential trade-offs can likely benefit from the added nutrition.
I personally plan to keep Approved Science Keto and Glutathione in my daily regimen for their cumulative effects over time. And I‘ll be sure to reach for Restlex on those occasional high-stress nights I need extra help relaxing.
Top Alternatives to Consider
While Approved Science passed my in-depth evaluation, supplement needs and preferences can be highly individual. Before you buy, also consider these top-rated alternatives in each category:
For Ketosis Support: Perfect Keto or Zhou Nutrition Keto Drive
For Sleep & Restlessness: Alteril or Life Extension Enhanced Natural Sleep
For Immunity & Antioxidants: Lypo-Spheric Vitamin C or Micro Ingredients Liposomal Glutathione
Any quality regimen starts with diet, exercise, and lifestyle fundamentals. But strategic supplements can provide that additional 5-15% whole-body advantage. I hope this comprehensive review helps you make the best decision for YOUR needs! Please drop me any questions in comments.
Yours in health,
