A two-year supplement, training-support, and lab framework — built for high mileage, body composition shift, and midlife optimization.
Body composition, hypertrophy, and endurance pull in different directions. The protocol below is designed to manage that tension, not pretend it away.
Goal 1 — Drop body fat to visible six-pack. Requires a sustained ~300-500 kcal/day deficit. Compromises recovery and run quality if too aggressive. Satiety is the limiting variable; whole-food protein beats liquid every time.
Goal 2 — Build upper-body muscle and overall strength. Requires adequate protein (2.0-2.2 g/kg, ~160-175 g/day), progressive lifting, and recovery. Anabolic resistance starts to bite in the 40s — leucine threshold per meal (~2.5-3 g) becomes more important, not less.
Goal 3 — Build leg strength without breaking run training. Lower-body lifting timed away from key runs (24-48 hrs), bias toward heavy-low-rep work (3-5 reps, 80-90% 1RM) over volume — better strength-per-fatigue ratio.
The supplement stack below is built around this conflict: support recovery and adaptation aggressively, fill micronutrient gaps the deficit and high mileage create, and remove anything that's expensive theatre.
Timing matters more than people think. The stack is structured around three windows: morning fat-soluble loading, pre-training tendon synthesis, and pre-sleep nervous-system downshift.
Fat-soluble vitamins with breakfast fat (whole milk in espresso works). If iron is added later, take it at this window — but 2+ hrs from coffee.
This is the non-negotiable timing. Tendon collagen synthesis peaks ~30-60 min after this combo — taken pre-loading, it ~doubles synthesis vs. random-time intake. Critical with your mileage ramp.
Cadence: ~30-60 g carbs/hr for runs over an hour; bump to 60-90 g/hr at race pace. Sodium ~500-1,000 mg/hr in heat.
Recovery window matters less than total daily protein, but timing here is convenient. Real food with the shake — not the shake alone.
Aim for 35-50 g protein per feeding. Three feedings of 40 g beats five of 20 g for someone your age — better leucine pulse per meal.
Glycinate for nervous-system downshift, threonate for sleep quality and cognitive markers. Tart cherry has the best sleep data of any "natural" supplement. Casein only on lift days for overnight MPS.
The five everyone should take regardless of sport — calibrated for your demographic, training load, and the gaps a desk-job diet creates.
Desk worker, indoor light — almost certainly suboptimal without supplementation. K2-MK7 directs calcium away from arteries; relevant given midlife CV focus. Dose is provisional pending your 25-OH D level.
NSF · TGA TestedIFOS 5-star purity, low TOTOX (oxidation) score. Triglyceride form has better bioavailability than ethyl ester. Anti-inflammatory effect matters with high mileage; ApoB / triglyceride benefit matters at 42.
IFOS 5★ · Friend of the SeaHighest-bioavailability magnesium form, GI-gentle. Supports parasympathetic shift before sleep and muscle relaxation. Sweat losses on long runs deplete magnesium meaningfully.
NSF · cGMPThe only Mg form that meaningfully crosses the blood-brain barrier. Evidence base for sleep quality, NREM time, and cognitive markers in midlife adults. Pairs with glycinate — different sites of action.
Patented · MagteinCreapure is the only patent-grade monohydrate (German-sourced, >99.9% pure). Skip loading — saturation takes 3-4 weeks at 5 g/day, no benefit to faster. Benefits: high-intensity output, lean mass, plus emerging data on cognition and BMD in midlife.
NSF Certified for Sport · CreapureThe performance-specific layer. Beta-alanine loads slowly and stays. Nitrates and gels are situational. Electrolytes scale with mileage and heat.
Raises intramuscular carnosine, buffers H+ during high-intensity efforts. Real benefit at 1-4 min efforts and final-kick territory — your half goal pace, plus any 5K/10K. Effect is cumulative, not acute. Don't take pre-race; this isn't pre-workout.
NSF Certified for SportNitric oxide pathway → improved running economy ~1-2%. Most validated brand and dose. Skip mouthwash on race morning (kills the bacteria that convert nitrate to nitrite).
Informed SportHigh-sodium ratio matches actual sweat losses. Most products under-dose sodium. No artificial colors or junk amino acids. Switch to Skratch when you want ~20 g carbs in the bottle for longer efforts.
Clean ingredient listStay with what your gut tolerates in training. Practice race-day fueling protocol during long runs — never experiment on race day. Build gut tolerance to 60-90 g carbs/hr over weeks.
Ingredient transparencyGold standard for high-carb race nutrition. The hydrogel matrix lets you push 80-100 g carbs/hr with less GI distress. Used by virtually every elite marathoner. Worth the cost premium on race day only.
Informed SportWith mileage going from ~72 to ~120 mi/month, the failure point for most runners isn't muscle — it's tendons, ligaments, and fascia. The collagen protocol is the highest-leverage item in this entire document.
Sunflower lecithin emulsifier solves the clumping you hated about Transparent Labs. Highest tier of third-party testing. Use to fill protein gaps, not to replace whole food. Cap at ~30-40% of daily protein from powder.
NSF Certified for SportSlow-digesting (4-6 hr release) — supports overnight MPS. Real benefit shown in trained men (Res 2012, Snijders 2015). Anabolic resistance at 42 means you genuinely benefit from the extended amino acid window.
NSF Certified for SportThe Shaw/Baar lab protocol — taken pre-loading, ~doubles tendon/ligament collagen synthesis vs random-time intake. Daily without timing is just a fancy low-quality protein. With timing, it's tendon insurance during your mileage ramp.
NSF · Vit C formulatedBest sleep evidence base of any natural supplement — raises endogenous melatonin (Howatson et al., Pigeon et al.). Also blunts post-exercise inflammation and oxidative stress in endurance athletes. Capsule form avoids the sugar load of juice.
Clean Label · MontmorencyFor the June 7 half and every race after. Don't introduce anything new race week. Adjust nutrition, not supplements.
Maintain full stack. Reduce running volume 30-50% (taper). No new gels, no new foods. Practice the race-morning routine on a final easy run.
Carb-load: 8-10 g carbs/kg/day for 36-48 hrs (~700-900 g for you). Reduce fiber. Keep collagen daily; pause heavy lifting. Sleep is the limiting factor.
Magnesium stack + tart cherry pre-bed. Familiar dinner — pasta, white rice, lean protein. Lay out gear. No alcohol.
3-4 hrs out: 1-2 g carbs/kg. 2-3 hrs out: Beet It Sport shot. 60 min out: collagen + vit C if you want the tendon dose. 30 min out: caffeinated gel + sip electrolyte.
Maurten gel every ~25-30 min from minute 30 onward (3-4 gels for a 1:45 finish). Sip water + electrolyte at every aid station. Don't skip early fueling.
Within 30 min: 0.4 g/kg protein + 1-1.2 g/kg carbs (whey + bagel or rice). Resume normal stack next day. Double tart cherry the next 2-3 nights for inflammation control.
Primary picks are top-tier third-party certified. Backup picks are still clean and reputable — use when the primary is out of stock, on backorder, or running a long lead time on Amazon. Buy direct from manufacturer or Amazon Subscribe & Save for 5-15% off.
Bone density, immune function, and cardiovascular protection — K2 directs supplemental calcium away from arterial walls. Almost every desk-bound male in the Northeast runs low without supplementation.
Anti-inflammatory effect at high training loads, plus cardiovascular benefit (lowers ApoB and triglycerides). Critical at 42 for both running recovery and lipid panel.
Sleep onset, muscle relaxation, parasympathetic shift before bed. Replaces sweat losses on long runs (endurance athletes run lower on Mg than sedentary controls).
The only Mg form that crosses the blood-brain barrier. Targets sleep quality, NREM time, and cognitive markers — distinct from glycinate's peripheral muscle/nervous-system role.
ATP regeneration → power output, lean mass retention in a deficit, plus emerging cognitive and bone-density data for midlife adults. The most evidence-backed supplement in sport.
Raises intramuscular carnosine, buffers H+ during high-intensity efforts. Real benefit at 1-4 min efforts — your half-marathon goal pace and any 5K/10K kick.
Dietary nitrate → nitric oxide → ~1-2% running economy improvement. Validated for endurance race performance at the specific dose Beet It uses.
Replaces sodium, potassium, and magnesium lost in sweat on long runs and in heat. Sodium-forward (1 g/stick) matches real sweat losses better than most "hydration" products.
Quick carb delivery on training runs over 60 minutes. Use what your gut tolerates and rehearse race-day fueling here — never experiment on race day.
High-carb (60-100 g/hr) race nutrition without GI distress, courtesy of the hydrogel encapsulation that releases sugar lower in the GI tract. Race-day only.
Fast-acting protein for post-workout muscle protein synthesis and meal-gap filling. ~2.7-3 g leucine per scoop — clears the per-meal MPS threshold critical at 42.
Slow-release protein for overnight muscle protein synthesis on lift days. 4-6 hr amino acid drip extends the anabolic window through sleep — meaningful in your 40s.
Tendon and ligament substrate. Taken with vit C 30-60 min pre-loading, ~doubles collagen synthesis at the tendon. The single highest-ROI item during a mileage ramp.
Best sleep evidence of any "natural" supplement (raises endogenous melatonin). Blunts post-exercise inflammation and DOMS in endurance athletes. Capsule avoids juice's sugar load.
Cofactor for collagen synthesis — must be co-ingested with collagen peptides to make the pre-loading protocol work. Also general antioxidant support during high training loads.
Some are safety calls; some are pure expensive theatre. Either way, the money saved here funds the premium upgrades above.
Consumer Reports 2025: 400-600% of concern level for lead. CR's specific recommendation was a maximum of once per week. Discontinue today.
Plant-based meal replacement. Independent lab testing detected lead, cadmium, and arsenic. Cap at 1-2x/week if you love it; otherwise drop.
At 180 g/day total protein from complete sources, supplemental BCAAs are pharmacologically pointless and may slightly reduce MPS (Wolfe 2017). Expensive urine.
Under-doses sodium for real sweat losses; adds artificial sweeteners and unneeded amino acids. LMNT is cleaner and better matched to physiology.
Same parent-company concerns as the plant protein line. Switch to Momentous Collagen Peptides — same form (hydrolyzed bovine), pre-formulated with vit C, NSF Certified for Sport.
TL clumps because no lecithin emulsifier — you've already noticed. Consolidate to one clean isolate (Momentous or Klean) for consistency.
The BMP you sent is the smallest possible lab panel. Below is what actually drives stack decisions for a 42-year-old male endurance runner. Frame for your PCP: endurance athlete, high training load, body comp and longevity focus.
IF ferritin < 50 ng/mL: add Thorne Iron Bisglycinate 25-36 mg with vit C, 2+ hrs from coffee/tea/calcium.
IF < 20 ng/mL: see a sports physician; consider IV iron.
IF < 40 ng/mL: confirm 5,000 IU dose, recheck 90 days. Target 50-80 ng/mL.
IF > 60 ng/mL: drop to 2,000 IU maintenance.
IF ApoB > 90 mg/dL: discuss with PCP. Lp(a) is genetic — one-time test. Statin discussion separate.
IF free T low-normal: separate optimization protocol — sleep, body fat, zinc, possibly boron. HRT is a downstream conversation, not a first move.
IF hsCRP > 2 mg/L: investigate source — training stress, body fat, diet, sleep. Not a supplement problem.
Calculate HOMA-IR. Endurance athletes occasionally show paradoxical insulin resistance — worth a baseline.
IF B12 < 400 pg/mL or homocysteine > 9: methylated B-complex.
Endurance + deficit can suppress thyroid. Baseline before chasing fatigue with supplements.
OmegaQuant direct-to-consumer (~$50). Target > 8%. If < 4%: increase Ultimate Omega 2X to 3-4 softgels/day temporarily.
