Most people aren't missing effort—they're missing a strategy.
Every system has a starting point. These are ours. Hand-picked from across the catalogue — the products we'd recommend to anyone walking through the door for the first time.
✓ Three-mechanism cellular longevity system✓ Glutathione clears oxidative damage daily✓ NMN restores NAD+ for cellular repair✓ Methylene Blue optimises mitochondrial efficiency Why this formula Most longevity stacks duplicate function — multiple antioxidants, multiple energy precursors aimed at the same target. This pairs three distinct mechanisms instead: glutathione clears the oxidative damage that accumulates daily, NMN restores the NAD+ your cells need to act on that damage, and methylene blue improves the efficiency of the mitochondria doing the repair work. Taking any one alone addresses a single stage of the process; taking all three addresses damage, energy, and the system that turns that energy into repair — which is why they're paired rather than sold as standalone add-ons. Product overview A three-product cellular longevity stack pairing Liposomal Glutathione, Methylene Blue, and pure NMN — each intervening at a different point in cellular ageing, from oxidative damage to mitochondrial energy production. How to use Take Liposomal Glutathione (5mL) on an empty stomach, NMN (500mg) dissolved in water once daily, and BLU3 (1–10 drops) as tolerated. Methylene blue should not be combined with SSRIs, SNRIs, or used during pregnancy. Who it’s for Interested in longevity and cellular health as a long-term daily practice Wants research-backed compounds rather than a general multivitamin Building a structured RESTORE longevity routine What’s inside Cymbiotika Liposomal Glutathione (Reduced Glutathione, CoQ10, PQQ) · HEALR BLU3 Methylene Blue 1.3% · myBrainCo NMN Powder 500mg
✓ Reduced glutathione — the active, usable form✓ CoQ10 and PQQ for mitochondrial energy✓ Liposomal delivery protects through digestion✓ Supports detox and cellular longevity Why this formula Reduced glutathione is the active form cells can use immediately, unlike L-glutathione which requires conversion first. PQQ and CoQ10 extend this into mitochondrial energy support. Product overview A liposomal formula delivering reduced glutathione — the body's master antioxidant — alongside CoQ10, PQQ, and Riboflavin to support detoxification, mitochondrial energy, and protection against oxidative stress. How to use Take 5mL on an empty stomach, at least 20 minutes before meals. Recommended 6-days-on, 1-day-off protocol. Who its for Focused on healthy ageing and cellular longevity High oxidative load from exercise, stress, or environment Wants liver detoxification and immune resilience support What’s inside Reduced glutathione · CoQ10 (Ubiquinol) · PQQ · Riboflavin (B2)
✓ 10,000mg VERISOL® — up to 20x powder absorption✓ Clinically shown to improve skin elasticity✓ Strengthens hair and nails✓ Liquid format absorbs faster than powder Why this formula Most collagen is poorly absorbed because the molecules are too large. VERISOL® is hydrolysed into peptides small enough to actually reach the skin, in a liquid format that absorbs faster than powder. Product overview A daily liquid marine collagen delivering 10,000mg of clinically studied VERISOL®, designed to support skin elasticity, reduce fine lines, and strengthen hair and nails. How to use Take one sachet daily, alone or in a smoothie. Not suitable for fish allergies, vegetarians, or vegans.

✓ Blocks 100% blue and green light✓ More complete than blue-only glasses✓ Premium frame with spring hinges✓ Scratch-resistant lenses Why this formula Green light delays melatonin release just as blue light does, but most blue light glasses leave it unaddressed. The red lens covers both ranges for more complete protection. Product overview Premium red-lens glasses blocking 100% of both blue and green light — the most thorough evening light protection in the range, in a durable everyday frame. How to use Wear 1–2 hours before bed. Evening use only — the colour shift takes a night or two to adjust to. Who its for Wants the most complete evening light protection available Spends evenings on screens or under bright LED lighting Wants a proper everyday frame, not a fitover Key Specs Nocturnal Red 550 lens · 127g · Available in Black, Crystal, Pearl Grey, Tortoise Shell

✓ Nootropic support, brain magnesium, systemic magnesium✓ BacoMind® Bacopa for memory and learning✓ Magtein® crosses the blood-brain barrier✓ Two magnesiums, two different jobs Why this formula Standard magnesium supplements don't reach the brain in meaningful amounts, which is the gap Magtein® closes — but magnesium's role in cognition isn't limited to brain tissue. Magnesium Breakthrough covers the muscle, nervous system, and cardiovascular pathways that a brain-targeted form leaves unaddressed, while Sharp Mind works through a completely separate mechanism — herbal nootropics that build their effect over weeks, independent of magnesium status entirely. Each product addresses a layer the other two don't touch, so stacking them covers structural brain support, systemic mineral function, and long-term nootropic build-up at once, rather than three attempts at the same outcome. Product overview A three-product cognitive stack combining a nootropic capsule, brain-targeted magnesium, and full-spectrum magnesium — supporting memory, focus, and mental clarity from multiple angles at once. How to use Take Sharp Mind (2 capsules each morning with food), Magnesium L-Threonate (1 sachet daily), and Magnesium Breakthrough (2 capsules daily, ideally evening). Allow 4–8 weeks for full cognitive effects to build.

Key Benefits: ✓ Mitochondrial energy, protein, and endurance covered✓ Shilajit lays the mineral foundation✓ WPI with mushroom complex for recovery✓ Stimulant-free Cordyceps for endurance Why this formula Performance breaks down into three separate time horizons, and each product here covers one. Shilajit works on ongoing cellular capacity — the mitochondrial fuel supply that determines your baseline energy day to day. WPI with its mushroom complex works on the rebuilding side — amino acids for muscle repair plus the gut and immune support training stress depletes. Stamina Surge works in the moment, extending endurance and reducing perceived effort during the session itself, without relying on caffeine to do it. None of the three substitutes for the others — they're addressing baseline energy, post-session recovery, and in-session output as three distinct problems rather than one supplement trying to cover all three at once. Product overview A three-product performance stack pairing mineral-rich Shilajit, a mushroom-infused whey protein, and a stimulant-free endurance elixir — supporting energy, recovery, and physical output from training through to daily life. How to use Take Shilajit (0.5–1g dissolved in warm water), WPI as a post-training shake, and Stamina Surge (1 dropper) 30 minutes before training or any time for daily energy.

Most people aren't failing at wellness — the information available to them is. Conflicting advice, overcrowded shelves, and products that promise everything make it nearly impossible to know what to take, when to take it, or why it even works.
The result? People spend money on supplements they don't understand, follow routines that don't hold together, and quietly wonder if any of it is actually doing anything. That's not a personal failing—it's a system failure. Welcome to Citadel.
