Frequently Asked Questions
- What is Consumer Review?
- An independent supplement review site providing honest comparisons across five health categories since 2003. Our reviews are compiled from independent research, consumer-submitted reviews, and our review staff's analysis. We do not sell any of the products we review.
Frequently Asked Questions
Products are rated based on five criteria: guarantee (if any), pricing, ingredients and formulation, customer support and reputation, and user-reported results. Our review staff compiles data from independent research and consumer-submitted reviews to generate overall scores.
Most supplements require consistent daily use over several weeks. Hair loss supplements: 3-6 months. Skin care products: 1-2 months. Antioxidants: 4-8 weeks. HGH supplements: 4-8 weeks. Joint support: 4-8 weeks. If a product claims results in days, be skeptical.
Yes. A money-back guarantee is one of the most important factors to consider. Companies that stand behind their product offer one. Look for at least a 30-day guarantee, though 60 or 90 days is preferable since many supplements take weeks to show results.
Dietary supplements do not require pre-market FDA approval. They are regulated under the Dietary Supplement Health and Education Act (DSHEA) of 1994. The FDA can take action against unsafe products after they reach the market. This is why third-party testing and manufacturer reputation matter.
No. Consumer Review does not sell any products. We provide links to manufacturer websites for your convenience. Please contact manufacturers directly for ordering, returns, or product questions.
See a doctor if your symptoms are severe or worsening, you're on prescription medication (supplements can interact), you have a diagnosed medical condition, or you've used a supplement for 3+ months with no improvement. Supplements work best for mild-to-moderate issues and preventive maintenance.
Who Should Consider Supplements?
| Profile | Potential Benefit | Realistic Expectation |
|---|---|---|
| Adults with identified nutritional gaps | Targeted supplementation based on bloodwork | Measurable improvement in deficiency markers |
| Active adults with elevated nutrient needs | Recovery support, performance optimization | Modest benefits alongside proper nutrition |
| Adults 50+ with age-related absorption changes | Vitamin D, B12, calcium, magnesium | Maintenance of levels that naturally decline with age |
| People researching supplement quality | Independent reviews and comparisons | Evidence-based guidance to avoid wasting money |
Not ideal for: Anyone expecting supplements to replace a balanced diet, individuals with kidney or liver conditions (some supplements can be harmful), children without pediatric guidance, or anyone taking prescription medications without checking for interactions first.
Considerations and Limitations
- Dietary supplements are not evaluated by the FDA for safety or efficacy before reaching market
- More is not better. Excessive intake of fat-soluble vitamins (A, D, E, K) can cause toxicity
- Supplement quality varies dramatically between brands. Third-party testing (USP, NSF, ConsumerLab) is the most reliable quality indicator
- Many supplements interact with prescription medications. Always consult a pharmacist or healthcare provider before starting a new supplement
- Marketing claims on supplement labels frequently exceed what clinical evidence supports
