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. Its best-known SKU is the “Longevity Stack,” a six-ingredient capsule pack pitched for cellular repair and metabolic support. Subscription discounts (15 %) and a 60-day refund policy reinforce a science-first, risk-free positioning. Core buyers are 30-55-year-old biohackers, quantified-self athletes, and health professionals who track biomarkers and want off-label access to longevity molecules without compounding pharmacies. 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

Youth & Earth

Youth & Earth sells longevity-focused dietary supplements and skincare, led by NAD+ boosters (NMN, NR, NAD+ nasal sprays), spermidine, resveratrol, fisetin and transdermal creams. Single-item prices run £29–£89; most 30-day servings sit £40–£60, placing the brand in the mid-range tier. All commerce is DTC through youthandearth.com with global shipping from UK and EU warehouses; no retail stores or third-party marketplaces are used. The company positions itself as “science-first, purity-proven,” publishing third-party COAs for every batch and using vegan, non-GMO, allergen-free excipients. Novel formats—sublingual powders, enteric-coated capsules and dual-action NAD+ regimens—have made their 500 g NMN pouch and 12,000 mg spermidine one-month pack repeat best-sellers among UK biohackers. Core buyers are 30-55-year-old professionals who self-track biomarkers, follow fasting or keto protocols and want UK-stock, Brexit-compliant longevity molecules without import duty. The brand voice stresses transparency, age-reversal research and measurable results, resonating with data-driven wellness communities on Reddit and Twitter. Youth & Earth competes with US-centric peptide and NAD+ suppliers that ship from overseas; it differentiates by holding UK/EU inventory, publishing contaminant data, offering subscription discounts up to 25 % and providing same-day London courier service, eliminating the long customs waits and cold-chain risks common in the niche.

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.

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

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.

Dr Stanfield

Dr Stanfield sells physician-formulated dietary supplements that focus on gut health, immune support and healthy aging. Single bottles run $35-$55 and 3-pack bundles drop the per-unit cost to the low-$30s, placing the line in the mid-range tier. All inventory is sold direct-to-consumer through drstanfield.com; no retail or third-party e-commerce listings are used. The brand’s point of difference is that every capsule, powder or soft-gel is designed by Dr. James Stanfield, a board-certified M.D. who publishes ingredient rationale and third-party lab certificates on each product page. Flagship SKUs include “Gut Restore” (a spore-based probiotic plus post-biotic blend) and “NMN + Resveratrol,” a two-capsule longevity combo that has driven most of the site’s five-star reviews. Core buyers are health-conscious adults aged 35-60 with discretionary income who research PubMed links before purchasing and value transparency over celebrity endorsements. They typically follow intermittent-fasting or bio-hacking routines and want small-batch, USA-made formulas from a single clinician rather than a conglomerate catalog. Competitors range from low-cost Amazon probiotics to premium longevity brands sold through subscription wellness platforms. Dr Stanfield differentiates by limiting the catalog to six SKUs, offering one-time purchases with no auto-ship default, and backing every batch with publicly viewable COAs linked to the exact lot number on the bottle.

One doctor's formulas, one batch at a time, complete transparency

pharmagetics

Pharmagetics sells physician-formulated nutraceuticals and cosmeceuticals built around DNA-guided personalization. Core lines include pharmacogenomic test kits ($149–$299), custom-compounded vitamin packs ($89–$129 per month), and targeted skincare serums ($45–$95); all sit in the premium price tier. Distribution is DTC e-commerce only through the brand’s own site and an accompanying mobile app that delivers results and reorder prompts. The company’s central claim is “precision nutrition based on your genome”: customers upload or swab for 60+ pharmacogenomic variants, then algorithms translate the data into capsule, cream, or powder formulas with excipient levels adjusted to the individual. Flagship SKUs are the PGX-Rx multivitamin (color-coded to metabolic speed) and the Telo-Extend telomere serum, both repeatedly cited in functional-medicine podcasts for their data-driven dosing. Buyers are 30-55-year-old professionals who already track sleep, HRV, or micro-nutrients and want to extend that quantified approach to supplementation; 68 % of purchasers arrive via longevity or bio-hacker forums. The brand frames health as an optimizable system, appealing to values of scientific self-experimentation, transparency, and skepticism of one-size-fits-all RDAs. Pharmagetics competes with both mass custom vitamin startups and high-end genetic health platforms; it differentiates by integrating prescription-grade compounding (all formulas made in an FDA-registered 503A pharmacy) with actionable drug-gene interaction warnings that reference FDA tables, a step most lifestyle-oriented DNA kits skip.

Rootspharm

Rootspharm.net is an online-only apothecary that focuses on herbal tinctures, powdered adaptogens, and encapsulated botanical blends sold in 30- to 120-count or 30-ml to 100-ml sizes. Price points sit in the mid-range band: single herbs start at $14, while curated 3-week protocols reach $68; no retail storefronts or third-party marketplaces are used—everything ships from their Texas warehouse. The brand differentiates by combining USDA-certified organic raw herbs with small-batch, dual-extraction processing verified by third-party labs; every bottle carries a QR code linking to potency and contaminant results. Their best-known SKUs are “Lion’s Mane + Bacopa Focus Blend” and the post-antibiotic “Gut Root Restore,” both highlighted in functional-medicine podcasts for standardized β-glucan and berberine content. Customers are 25-45-year-old wellness seekers who track macros, cycle nootropics, and prefer transparent sourcing over mere “clean label” claims; the site’s blog on mycelium vs. fruiting-body science draws 60 k monthly views, signaling an audience that researches before buying. Sustainability and fair-trade partnerships with North American herb cooperatives align with their value set. Rootspharm competes with mass-market supplement pills and upscale adaptogenic lifestyle powders; it separates itself by avoiding proprietary blends—every milligram is itemized—and by limiting SKUs to 32 tightly focused formulas rather than trend-chasing flavor packets or gummies.
