Yes. I checked the current NSF listings, including NSF's official databases. One important distinction: “NSF Certified” and “NSF Certified for Sport” are not the same. NSF Certified for Sport adds screening for banned substances and is the better choice for athletes or anyone wanting the strongest NSF verification. www.nsf.orgtrust.nsf.org

### My top NSF-certified choices in the U.S.

| Supplement | Good NSF-certified choice | Best for | |---|---|---| | Protein | Optimum Nutrition Gold Standard 100% Whey | Muscle/recovery | | Daily greens/multinutrient | AG1 | Convenience/all-in-one | | Omega-3 | Momentous Omega-3 | EPA/DHA supplementation | | Multivitamin | New Chapter Every Woman's One Daily | Women's multivitamin | | Omega-3 | New Chapter Wholemega 1000 mg | General omega-3 | | Vitamin D | NatureWise Vitamin D3 | Vitamin D supplementation |

Optimum Nutrition Gold Standard 100% Whey is specifically listed by NSF as Certified for Sport in the U.S.; the NSF listing shows 24 g protein per serving for the Double Rich Chocolate version. nsfsport-prod.nsf.org

For omega-3, NSF's current dietary-supplement listings include Momentous Omega-3, New Chapter Wholemega, and several other products. info.nsf.org

For vitamin D, the current NSF database includes several NatureWise D3 products, including 1,000 IU, 2,000 IU, 4,000 IU and 5,000 IU versions. info.nsf.org

### 🏆 If I were choosing a simple stack

For general health: 1. Multivitamin - only if your diet has gaps 2. Omega-3 - particularly if you rarely eat fatty fish 3. Vitamin D3 - preferably based on your vitamin-D status/diet 4. Protein powder - if you don't get enough protein from food

For gym/fitness: - Optimum Nutrition Gold Standard 100% Whey - NSF Certified for Sport - Creatine monohydrate - look specifically for NSF Certified for Sport - Omega-3 if appropriate

I would not automatically recommend an expensive “all-in-one” supplement just because it carries NSF certification. NSF verifies quality/contents; it doesn't mean every ingredient or product is necessary for you. NSF itself distinguishes its foundational Contents Certified program from the enhanced Certified for Sport program. trust.nsf.org

Best place to verify any product before buying: NSF Certified Product Search - you can search the exact product and, for Certified for Sport products, even check lot information. nsfsport-prod.nsf.org

If you tell me your goal - men's/women's health, muscle gain, energy, heart health, vitamins, or anti-aging - I can narrow this to the 5 best NSF-certified products and current U.S. prices.

The strongest sustainable supplement brands available in the U.S. are Nordic Naturals, Garden of Life, Thorne, MegaFood, and AG1-but the best choice depends on whether you prioritize sustainable sourcing, packaging, certifications, or product testing.

- Nordic Naturals - Best for omega-3s. The company emphasizes sustainably sourced fish oil and has manufacturing sustainability credentials, including LEED Gold certification. - Garden of Life - Best for organic and plant-based supplements. It is associated with USDA Organic, Non-GMO Project Verified, B Corp, and carbon-neutral claims, though certifications can vary by product and ownership period. - Thorne - Best for rigorous quality control. It is frequently included among brands with independently verifiable sustainability or responsible-manufacturing efforts, although its environmental packaging options are less prominent than some competitors. - MegaFood - Best for whole-food-based vitamins. It has been identified alongside Nordic Naturals, Garden of Life, and Thorne as a brand with meaningful third-party sustainability credentials. - AG1 - Best for an all-in-one greens powder. It has held Climate Neutral certification and supports emissions-reduction and forest-protection projects, but single-use packets and subscription pricing may reduce its overall sustainability advantage. - Terraseed - Best for low-waste vegan vitamins. Its products use biodegradable bottles and focus on vegan formulations.

Best overall shortlist:

1. Nordic Naturals for fish oil 2. Garden of Life for organic vitamins 3. MegaFood for whole-food multivitamins 4. Terraseed for lower-waste vegan supplements 5. Thorne when testing and formulation quality matter most

Before buying, check the specific product label for certifications such as USDA Organic, Non-GMO Project Verified, MSC or Friend of the Sea for marine ingredients, Climate Neutral, B Corp, and third-party contaminant testing. Sustainability claims often apply to only certain products rather than an entire brand.
