Frequently asked questions.

Most supplements are formulated based on marketing trends, not science. Nuclora starts with the peer-reviewed literature — we identify the compounds, forms, and doses with actual clinical evidence, then manufacture to pharmaceutical standards. Every ingredient is disclosed with its exact dose. We never use proprietary blends.

Yes. Every production batch is tested at an independent, ISO 17025-accredited laboratory. Our key products carry NSF Certified for Sport® certification, which tests for 270+ banned substances and confirms label accuracy. Certificates of Analysis are available on request.

Nuclora products are free from gluten, dairy, soy, and artificial additives. Our Omega-3 Ultra Pure contains fish (the source of EPA and DHA). All allergen information is listed on each product page.

Most Nuclora products are vegan-friendly. Omega-3 Ultra Pure and D3+K2 Protocol contain fish or animal-derived ingredients. These are disclosed clearly on the product pages.

Pharmaceutical grade means our manufacturing facilities, processes, and testing standards meet or exceed FDA Current Good Manufacturing Practice (cGMP) regulations — the same standards applied to pharmaceutical drug manufacturing. This includes purity verification, contamination screening, and strict batch documentation.

We use both. NMN and NR target different metabolic pathways for NAD+ replenishment, and research suggests they have complementary tissue-level uptake profiles. Our Cellular NAD+ Complex includes both at clinically relevant doses, along with resveratrol to amplify SIRT1 activation.

Ubiquinol is the active, reduced form of CoQ10 — the form your cells actually use. Ubiquinone must be converted to ubiquinol in the body, a conversion that becomes less efficient with age. Nuclora uses Kaneka QH™ ubiquinol because studies show it absorbs at roughly 2.5× the rate of ubiquinone.

Triglyceride-form omega-3s are the natural form found in fish and absorb significantly better than ethyl esters, the cheaper form used in most supplements. Clinical data shows up to 70% better bioavailability. They also do not require food for absorption.

Every dose in every Nuclora formula is derived from human clinical trials. We identify the dose ranges used in peer-reviewed studies showing positive outcomes, and we dose at or above the lowest effective dose in those studies. We do not under-dose to reduce costs.

Yes. Our products are formulated to work well together. Common combinations include NAD+ Complex + Omega-3 Ultra for longevity, or Mitochondrial Activator + Cognitive Clarity for performance. If you have specific health conditions or take medications, consult your physician.

This varies by product and individual. Some compounds like L-theanine and magnesium have acute effects within hours. Compounds like Lion's Mane, bacopa, and NAD+ precursors build cumulative benefits over 4–12 weeks. We recommend a minimum 90-day protocol for full assessment.

Most Nuclora products should be taken with food. Fat-soluble nutrients (D3, K2, CoQ10, omega-3s) absorb significantly better alongside dietary fat. Each product page includes specific timing recommendations.

Our key performance products are NSF Certified for Sport®, which tests for 270+ substances on the WADA banned substance list. Athletes competing in anti-doping regulated sports should use NSF-certified products specifically. Check individual product pages for certification status.
