Longevity Method

Longevity Method sells physician-formulated supplement stacks, at-home blood & epigenetic test kits, and personalized digital protocols priced USD $69–$349; all commerce is DTC through longevity-method.com, no retail. The brand positions itself as a “longevity concierge,” combining MD-designed nutrient synergies with follow-up biomarker tracking; its flagship “Longevity Stack” (NAD+ booster, senolytic, omega-3, micronutrient complex) is bundled with quarterly re-tests that adjust dosing. Core buyers are 30-55-year-old tech-savvy professionals who already track sleep, exercise, and diet and want data-driven, science-heavy interventions to slow biological aging; they value transparency, open-source ingredient lists, and published third-party lab certificates. Competitors include generic anti-aging pill lines and basic subscription vitamin packs; Longevity Method differentiates by integrating testing, AI-driven protocol updates, and medical-team oversight in one vertically integrated system, turning one-off supplement sales into an iterative longevity program.

Theworldsgreatestrejuvenation

Theworldsgreatestrejuvenation sells ingestible and topical nutraceuticals aimed at cellular repair, longevity and age-reversal. Flagship SKUs include NAD+ precursor capsules ($89 for 30), liposomal spermidine tonics ($120), and red-light-activated peptide serums ($150); the range sits firmly in the premium tier. All commerce is DTC through the brand’s own site; no third-party marketplaces or physical retail. The company positions itself as a “rejuvenation protocol” rather than a supplement line, bundling biomarker testing kits with each first order so buyers can track biological-age reduction over 90-day cycles. Products are formulated in FDA-registered, cGMP Swiss labs and shipped in cold-chain packaging to preserve peptide stability—details heavily emphasized in content marketing. Its best-known bundle, the “Age-Reversal Starter,” combines NAD+, fisetin and a topical GHK-Cu serum and accounts for 40 % of revenue. Core customers are 35-60-year-old tech professionals and bio-hacking enthusiasts who already track sleep, HRV and glucose and are comfortable self-injecting or stacking multiple molecules. They value quantified-self data, open-source research citations and are willing to pay 2-3× standard supplement prices for patented raw materials and third-party Certificates of Analysis. Competitors include other premium longevity supplement houses, prescription peptide clinics and upscale wellness spas selling similar protocols. Theworldsgreatestrejuvenation differentiates by integrating at-home epigenetic testing, personalized dosage dashboards and subscription refills timed to test-retest windows, creating a closed-loop ecosystem that positions the brand as a science service rather than a product retailer.

Measure your biological age, then actually reverse it

Longevityreserve

Longevityreserve operates a direct-to-consumer e-commerce store focused on premium anti-aging nutraceuticals and biomarker testing kits. Core SKUs include NAD+ precursors, resveratrol, spermidine, fisetin, and combination “longevity stacks” sold in 30-day glass-jar supplies; most items sit between USD 79 and USD 199, positioning the brand at the upper-mid to premium tier of the supplement market. Sales are online-only through longevityreserve.com, with global DHL shipping from U.S. and EU fulfillment nodes. The company differentiates by pairing each product with third-party COAs displayed via QR code and by offering an optional at-home epigenetic age-test that integrates results into a personalized dosing dashboard. All capsules are formulated without fillers in cGMP facilities, bottled in violet glass to limit oxidative degradation, and shipped in insulated, carbon-neutral packaging—details heavily emphasized in product pages and investor decks. Customers are predominantly 35-55-year-old tech professionals and quantified-self enthusiasts who already track sleep, HRV, and glucose and are willing to self-fund interventions that may extend health-span. The brand speaks to values of scientific rigor, transparency, and self-experimentation rather than aspirational wellness culture. Longevityreserve competes in the narrow but fast-growing “longevity biohacking” supplement space populated by niche formulators and functional-medicine private labels. It separates itself by bundling high-purity single compounds with verifiable lab data and a digital feedback loop, moving the purchase from a commodity capsule to an ongoing data-driven optimization service.

Measure your biology, optimize with science, actually age slower

Coastlinelongevity

Coastlinelongevity sells oral longevity supplements—NAD+ precursors, spermidine, fisetin, Ca-AKG, and combo “stacks”—in 30- to 90-capsule bottles. Single-unit prices run $39–$89, putting the line in the mid-range tier between mass-market multivitamins and high-end prescription peptides. All fulfillment is direct-to-consumer through the brand’s own site; no retail or marketplace listings are used. The company formulates around peer-reviewed geroscience, publishes third-party COAs for purity and heavy-metal content, and uses glass bottles with desiccant inserts to maximize stability.

The brand speaks to values of data-driven wellness, transparency, and proactive aging rather than reactive treatment. Coastlinelongevity competes with boutique nootropic and anti-aging supplement start-ups that also sell single-molecule capsules online. It differentiates by bundling synergistic ingredients, batch-testing every lot, and avoiding proprietary blends so milligram dosages are fully disclosed.

Your cells are aging on a schedule you can actually change

Hello100

Hello100 is a direct-to-consumer longevity-science brand that sells NAD+ precursors, liposomal NMN and NR capsules, trans-resveratrol, spermidine, fisetin, and complementary methyl-vitamin complexes. All SKUs are priced in the premium tier: single-bottle NMN 60-count runs ≈ $70, while curated 3-month “Longevity Starter” bundles reach ≈ $220. Distribution is online-only through hello100.com and Amazon storefronts; no retail presence. The company positions itself as “science-first” by publishing third-party Certificates of Analysis for purity ≥99 % and heavy-metal limits, using dual-patented liposomal delivery that claims 3× bioavailability versus standard NMN. Its hero SKU, Liposomal NMN 500 mg, is frequently cited in biohacker forums for noticeable energy uptick within two weeks, and the brand offers a 60-day money-back guarantee even on opened bottles. Core buyers are 30-55-year-old professionals who track biomarkers, practice intermittent fasting, and want to slow cellular aging; 68 % of repeat orders come from customers who also own wearables or subscribe to InsideTracker. Messaging stresses “data-driven aging” and stacks that pair with active lifestyles rather than treating disease. Hello100 competes in the crowded NAD-boost supplement space against both low-cost bulk-powder sellers and celebrity-backed longevity brands. It differentiates through transparent lab data, liposomal technology patents, and subscription pricing that undercuts equivalent liposomal formulas by ~15 % while still positioning as premium science, not commodity vitamins.

Proven cellular fuel for biohackers who measure everything

InfiniWell

InfiniWell sells physician-formulated longevity and metabolic-health supplements that fall into four core lines—NAD⁺ boosters, senolytics, AMPK activators, and precision hormone support. Single-bottle prices run $79–$149, placing the brand in the premium tier; 3-pack bundles drop the per-unit cost by roughly 15%. Distribution is DTC e-commerce only, shipped from Texas to the U.S. and Canada. The company differentiates by publishing exact ingredient weights, third-party COAs, and the prescribing protocols of its integrative-physician founders on every product page. Flagship SKU “NAD⁺ Max” delivers 1,000 mg nicotinamide riboside plus 500 mg apigenin in two capsules—one of the highest single-dose NR formulas on the market. All capsules are made in NSF-certified facilities and packaged in UV-blocking amber glass to satisfy clinician buyers. Core customers are 35- to 60-year-old biohackers, functional-medicine patients, and anti-aging physicians who want research-backed stacks without proprietary blends. Buyers typically track biomarkers (NAD⁺ levels, HbA1c, biological-age clocks) and value transparent dosing over celebrity endorsements. InfiniWell competes in the clinical-grade longevity niche against brands that also target cellular pathways but often use lower actives or hide behind “complex” labels. It counters with full-label disclosure, practitioner protocol sheets, and lot-specific COAs, positioning itself as the prescriber’s alternative to mass-market “wellness” pills.

Wearemikra

Wearemikra is a direct-to-consumer wellness brand that sells ingestible cellular-health supplements and powdered “super-cell” blends. The line-up centers on single-ingredient capsules (e.g., pure C15:0, astaxanthin, spermidine) and targeted stacks for skin, cognition, and longevity, priced USD $29-$79 per 30-day supply—solidly mid-range. Sales are online-only through wearemikra.com and Amazon; no retail distribution. The brand’s hook is “cell-first” nutrition: every SKU is built around peer-reviewed longevity compounds, third-party tested for ≥98 % purity, and delivered in lipid or cyclodextrin carriers that claim 3-5× higher cellular uptake. Flagship SKU “Cell-Therapy” combines C15:0, fisetin, and spermidin-R in one daily sachet and accounts for roughly half of recurring revenue. Core buyers are 25-45-year-old urban professionals who track HRV, follow Huberman-type podcasts, and want research-backed biohacks without prescription hoops. Sustainability and clean-label credentials (vegan capsules, carbon-neutral pouches) reinforce a “optimize today, age better tomorrow” value set. Mikra competes in the crowded longevity-supplement aisle against science-forward, DTC pill brands. It differentiates by limiting SKUs to molecules with human ORAC or senolytic data, publishing Certificates of Analysis on every batch page, and offering a 60-day “feel-it-or-free” guarantee—uncommon risk-reversal in the category.

SRW

SRW (Science Research Wellness) sells oral longevity supplements that target cellular repair, immune resilience, joint health, cognition, and skin. Single bottles run NZD 79–139 (≈ USD 50–90), placing the range in mid-to-premium territory; multi-unit “Cel” system bundles climb above NZD 300. All commerce is direct-to-consumer through the brand’s own site with global shipping; no brick-and-mortar stockists are listed. Formulations are built around patented or trademarked complexes—e.g., Cel1 with Hobamine 2-HOBA, Cel2 with NMN and CoQ10, Cel3 with spermidine and fisetin—each paired with peer-reviewed white papers downloadable from the product pages. The company positions itself as “cellular system maintenance,” translating academic aging research into three sequential daily capsules rather than the typical single-ingredient booster. Core buyers are 35-60-year-old professionals in Australasia and North America who track biomarkers, follow longevity podcasts, and want evidence-linked stacks without compounding raw powders themselves. The brand speaks in data (clinical graphs, scientist quotes) and promises “function now, resilience later,” aligning with quantified-self values more than generic wellness aspiration. SRW competes in the crowded anti-aging supplement space against single-molecule and broad-spectrum “longevity blends.” It differentiates by sequencing three complementary SKUs (Cel1-2-3) that mirror proposed hallmarks of aging, publishing open-access summaries for every active, and batch-testing in New Zealand–certified labs, giving consumers a transparent, protocol-ready stack rather than a kitchen-sink formula.
