Bone Density Support
About this protocol
Where to start
Start with vitamin D3 if your 25-OH vitamin D level is under 30 ng/mL. Vitamin D is required for calcium absorption; supplementing calcium without adequate D status is largely wasted.
Add vitamin K2 (MK-7). It directs calcium toward bones and teeth (via osteocalcin activation) and away from arteries. The combination of D3 + K2 has stronger evidence than D3 alone for bone-and-vascular safety.
Calcium — food first, supplement only to fill gaps. Most adults can hit the 1000-1200 mg daily target through dairy, leafy greens, sardines, and fortified foods. If your dietary intake is genuinely low, supplement 500 mg with each meal (the gut absorbs calcium in 500 mg increments — larger single doses are wasted).
Add magnesium glycinate. Magnesium is required for vitamin D activation and bone mineralization. Most adults under-consume magnesium.
Boron is the most speculative — small trials suggest effects on calcium retention and bone metabolism, but the literature is thin. Worth including in a "complete bone stack" but skip if you want simplicity.
This stack works only with adequate resistance training and protein. See lifestyle. Supplements alone cannot maintain bone density without mechanical loading.

Strongest evidence — the foundation of the stack.
Vitamin D3
2000-4000 IU daily, with breakfastVitamin D is required for intestinal calcium absorption — without adequate D status, calcium supplementation is largely wasted. Target serum 25-OH vitamin D of 30-50 ng/mL. Trial evidence for fracture prevention is mixed at lower doses but consistently positive when D status is corrected from deficient to replete. Fat-soluble; take with a fat-containing meal.[1, 2, 3]
Vitamin K2 (MK-7)
100-200 mcg daily, with the same meal as vitamin DVitamin K2 activates osteocalcin, the protein that binds calcium into bone matrix, and matrix Gla protein, which inhibits arterial calcification. K2 (MK-7 form specifically) has the strongest trial evidence for bone density and arterial calcification endpoints over 3 years. Critical complement to vitamin D — D alone increases calcium absorption but doesn''t direct it correctly without adequate K2.[4, 5, 6]
Add if needed
Add these only if the foundation isn't enough.
Calcium (only if dietary intake is low)
500 mg with each meal, only if total daily intake is below 1000-1200 mg from foodCalcium is the dominant structural mineral in bone, but supplementation has mixed evidence — some trials show benefit, others show cardiovascular risk from excess supplementation. Food-first is the right approach. Supplement only to fill genuine dietary gaps. The gut absorbs calcium in roughly 500 mg increments, so split doses are more effective than one large dose. Calcium citrate is better absorbed without stomach acid; calcium carbonate is cheaper but must be taken with food.[7, 8, 9]
Magnesium Glycinate
300-400 mg elemental, before bedMagnesium is required for both vitamin D activation and bone mineralization. Roughly 60% of bone mineral content involves magnesium. Most adults under-consume magnesium relative to RDA. Observational studies link adequate magnesium intake with better bone density. The glycinate form is gentle on the GI tract.[10, 11]
Experimental
Emerging evidence — try last, only if curious.
Boron
3-10 mg daily, with breakfastBoron is a trace mineral with small trials suggesting effects on calcium retention, magnesium retention, and bone-relevant hormone (estradiol, testosterone) metabolism. The literature is thin and the effect sizes are small. Treat as the most speculative item — include for completeness if interested, skip for simplicity.[12, 13, 14]
Warnings
Lifestyle improvements
Resistance training is non-negotiable
Bone is mechanically loaded tissue — without regular impact and load, no nutrient combination preserves density. Heavy resistance training 2-3× per week (squats, deadlifts, presses, pulls, loaded carries) is the single most effective intervention available. Cardio alone is insufficient.
Impact loading
In addition to weight training, brief bouts of impact (jumping, hopping, brisk running) stimulate bone remodeling. Even 10-20 jumps daily has measurable effects in bone-density trials.
Protein adequacy
Bone is 50% protein by volume (collagen matrix). Most adults under-consume protein. Aim for 1.2-1.6 g/kg body weight daily. Adequate protein is non-negotiable for bone maintenance, especially after 50.
Eat calcium-rich foods first
Dairy (yogurt, cheese, milk), sardines with bones, leafy greens, tahini, almonds, and fortified foods provide calcium with cofactors. A balanced eater easily hits 1000+ mg daily without supplementation.
Limit alcohol
Heavy alcohol use directly suppresses bone formation and increases fall risk. More than 2 drinks per day in women and 3 in men is associated with significantly reduced bone density.
Stop smoking
Smoking is one of the strongest reversible risk factors for osteoporotic fracture. Cessation produces measurable improvements in bone density within 12 months.
Get a baseline DEXA after menopause or at age 65
Bone-density scans (DEXA) every 2-5 years catch declining density before fracture. Earlier scans are warranted with risk factors (early menopause, family history, smoking, low body weight, certain medications).
Fall prevention matters as much as bone density
Strength, balance, and proper home setup (lighting, handrails, rugs secured) prevent the fractures that destroy quality of life. Tai chi has the strongest evidence for fall prevention in older adults.
Watch for sneaky bone-depleting medications
Long-term proton pump inhibitors (omeprazole), SSRIs, glucocorticoids, and certain anti-seizure medications all reduce bone density. If you''re on any of these long-term, your provider should be monitoring DEXA scans.

Other longevity protocols and protocols sharing ingredients with this one.
Foundational Longevity
longevity
Longevity supplementation is a noisy field. Most of the hype (NAD+ precursors, resveratrol, senolytics) rests on preclinical or short-term human data. What actually has long-term human evidence is unglamorous: correcting common deficiencies (vitamin D, omega-3), preserving muscle mass into late adulthood (creatine, protein), and supporting sleep and metabolic health. This protocol is the boring, evidence-backed foundation — start here before adding speculative add-ons.
NAD+ & Cellular Energy
longevity
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme essential for mitochondrial energy production, DNA repair (via sirtuins and PARPs), and cellular signaling. NAD+ levels decline measurably with age — roughly 50% by middle age in some tissues. The 2020s have seen explosive interest in NAD+ precursors (NMN, NR) as longevity interventions, popularized by researchers like David Sinclair. The honest framing: NAD+ precursors RELIABLY raise blood NAD+ levels in human trials. What''s less clear is whether this translates to meaningful longevity, cognitive, or healthspan endpoints in humans — most positive evidence is from animal models or small short-duration human trials. This stack is for adults interested in cellular energy support, especially over 40 — with the explicit caveat that this is experimental territory relative to the rest of the library. Foundational Longevity remains the better starting point for general healthspan; this protocol is for adults who want to specifically explore the NAD+ pathway.
Memory & Cognitive Aging
longevity
Cognitive function declines gradually starting in the late forties and accelerates around menopause for women and the late sixties for men. The supplement category is over-promoted ("brain pills" are an industry) but a handful of compounds have legitimate trial evidence in age-related cognitive decline. Phosphatidylserine is the most-evidenced compound for memory in older adults. Omega-3 (DHA-dominant) is foundational for brain structure. Citicoline and lion''s mane have emerging evidence. This protocol is distinct from Foundational Longevity (broad aging) and Deep Work Focus (acute cognitive performance) — it specifically targets memory, learning speed, and cognitive resilience as the brain ages. If you have rapid cognitive decline, personality changes, or someone close to you is concerned about your memory in a way you''re not — please see a neurologist. Early dementia is treatable when caught early. Supplements are not a substitute for proper neurological workup.
Systemic Inflammation Support
longevity
Chronic low-grade systemic inflammation (sometimes called "inflammaging") is a unifying mechanism behind cardiovascular disease, type 2 diabetes, neurodegeneration, autoimmune conditions, and accelerated aging. Unlike acute inflammation (which is necessary and beneficial), chronic inflammation drives tissue damage over years. Measurable markers include hsCRP, IL-6, TNF-alpha, fibrinogen, and homocysteine. This stack targets chronic inflammation through complementary mechanisms: curcumin (NF-kB and COX-2 inhibition with the bioavailability problem solved by phytosome forms), omega-3 EPA (shifts eicosanoid production toward less inflammatory series-3), quercetin (mast cell stabilization and NF-kB modulation), and boswellia (5-LOX inhibition through a distinct pathway). This is distinct from Joint Health & Mobility (osteoarthritis-specific) and Daily Calm (stress-driven). For systemic inflammation, the upstream causes — visceral fat, ultra-processed food intake, chronic stress, poor sleep, sedentary lifestyle — matter more than supplements. The stack is a complementary layer.
Daily Essentials — Foundation
general· 2 shared ingredients
Before any goal-specific protocol, most adults benefit from filling four common nutritional gaps: vitamin D3, magnesium, omega-3 EPA/DHA, and a basic multivitamin. These four cover the deficiencies that affect everything else — sleep, mood, immune function, energy, cognitive performance, and long-term cardiovascular and skeletal health. If you''re going to take only ONE protocol from Pilora, this is it. It''s the universal foundation. Everything else (Better Sleep, Daily Calm, Foundational Longevity, etc.) layers on top of this baseline. The framing here is unglamorous. There''s no novelty, no proprietary blend, no Instagram trend. Just the four supplements with the most consistent long-term human evidence for general health support.
Statin Companion
medication· 2 shared ingredients
Statins are the most-evidenced cardiovascular medication ever invented — they prevent heart attacks, strokes, and cardiovascular death across multiple massive trials. They''re also the most widely-prescribed class of medication in adults over 40. The catch: statins inhibit HMG-CoA reductase, the enzyme that produces cholesterol — but the SAME pathway also produces CoQ10 and dolichols. As a result, statin users show 19-54% reductions in serum CoQ10 in trials, and CoQ10 depletion is implicated in statin-associated muscle symptoms (the most common reason patients discontinue statins). Vitamin D status independently affects statin tolerance. Omega-3 complements statin lipid management. This protocol is for adults ACTIVELY on a statin medication (atorvastatin/Lipitor, rosuvastatin/Crestor, simvastatin/Zocor, pravastatin, etc.). The goal: mitigate side effects, support muscle and energy, complement cardiovascular protection. CRITICAL: this protocol does NOT replace your statin. Statins prevent cardiovascular events; the supplements address downstream effects. If you''re experiencing statin-related muscle symptoms, talk to your cardiologist or PCP. Options include CoQ10 supplementation, switching statin type, lowering dose, alternative-day dosing, or in rare cases switching medication class entirely. Don''t stop your statin without medical guidance.
