Calculate an evidence-based athlete recovery stack: creatine + tart cherry + curcumin + omega-3 + HMB by training intensity and goal. Targets inflammation, muscle catabolism, soreness, sleep quality. Warns about the anti-inflammatory paradox during hypertrophy training. Math, not medical advice. The anti-inflammatory paradox: high-dose antioxidants (curcumin, vitamin C, vitamin E) post-workout may BLUNT training adaptations […]

Convert between KSM-66, Sensoril, and generic ashwagandha extracts by withanolide content. “1,500 mg ashwagandha” on a label tells you almost nothing — the standardized extract amount (with withanolide %) is what matters. Math, not medical advice. The branded extract premium is real: KSM-66 (Ixoreal, full-spectrum root, 5% withanolides) and Sensoril (Natreon, root + leaf, 10%

Calculate apigenin dose by goal — sleep (Huberman 50 mg protocol), longevity / CD38 inhibition, anxiety. Most “chamomile tea sleep” effect is from apigenin’s GABA-A binding. Math, not medical advice. Honest framing: apigenin became popular via Andrew Huberman’s sleep stack (50 mg apigenin + 145 mg magnesium L-threonate + 100-400 mg theanine). Human RCT evidence

Calculate vitamin C dose by goal — RDA, immune support, iron co-factor, or bowel-tolerance protocol. Most absorption saturates around 200 mg per dose, so 1g+ single doses waste most of what you take. Split dosing matters. Math, not medical advice. The saturation truth: intestinal vitamin C absorption is dose-dependent and saturates. ~70-80% of a 200

Compare probiotic supplements by CFU count, strain diversity, and use-case match. A 50-billion-CFU product is not automatically better than a 10-billion one — strain identity matters more than dose. Math + product knowledge, not medical advice. Two things probiotic marketing hides: (1) CFU is measured at time of manufacture, not what reaches your gut —

Generate a custom probiotic schedule for your antibiotic course. Most people take probiotic the wrong way — bacteria-based probiotics taken with antibiotics get killed instantly. S. boulardii (yeast) survives. Calculator shows your optimal day-by-day timing. Math, not medical advice. The 2-hour rule: Lactobacillus and Bifidobacterium probiotics need 2-3 hour separation from antibiotic doses. Saccharomyces boulardii

A “1,000 mg fish oil” softgel typically contains 300 mg of actual EPA+DHA — the other 700 mg is non-omega-3 oil. Calculator decodes label math by goal (heart, triglycerides, brain, pregnancy). Trial-derived doses, not a prescription. The 70/30 trap: standard fish oil = 30% EPA+DHA. Concentrated fish oil = 60-90% EPA+DHA. The total fish-oil amount

Calculate the elemental magnesium you actually absorb from glycinate, citrate, oxide, and other forms. Two products labeled “500 mg magnesium” can deliver wildly different elemental amounts. Math, not medical advice. The trap: “500 mg magnesium glycinate” doesn’t mean 500 mg of magnesium. It means 500 mg of the magnesium-glycine compound, which is roughly 14% elemental

Calculate elemental iron by form. “65 mg ferrous sulfate” delivers different elemental iron than “65 mg ferrous bisglycinate.” Includes RDA + deficiency-correction protocols. New evidence on every-other-day dosing may double your absorption. Math, not medical advice. Stoltzfus 2017 and Moretti 2015 changed iron supplementation: daily oral iron raises hepcidin (a hormone that blocks iron absorption)

Calculate a support stack for GLP-1 medications (semaglutide / Ozempic / Wegovy, tirzepatide / Mounjaro / Zepbound, liraglutide / Saxenda). Addresses the five most common nutritional gaps: dehydration, muscle loss, B12 depletion, constipation, sarcopenia risk. Math, not medical advice — coordinate with prescriber. Why GLP-1 users need supplement support: reduced appetite means reduced total nutrient
