App nutrition review: 2026-09-07. Product-specific clinical advice requires an individual assessment.
Protein
General nutrition
Protein contributes to tissue maintenance. Exercise-related requirements depend on training and clinical context.
Intake or study context
Individual food-intake goal; no automatic g/kg target.
Food context
Fish, eggs, dairy, soy, beans and lentils.
Cautions & limits
A sports-nutrition target should not be applied automatically to kidney disease or every person using a peptide.
NIH ODS · Exercise and athletic performance
Protein and creatine sections. Exercise evidence does not establish peptide synergy.
Creatine monohydrate
Exercise evidence; indirect
Evidence supports some repeated high-intensity exercise outcomes. This does not establish benefit when combined with a peptide.
Intake or study context
Research context: 3–5 g/day maintenance in many exercise studies.
Food context
Meat and fish contain creatine; supplements deliver larger amounts.
Cautions & limits
Weight gain and gastrointestinal symptoms can occur. Review suitability with a clinician, especially with kidney disease.

Vitamin C
General nutrition
Needed for normal collagen formation; correcting inadequate intake differs from proving extra benefit from high doses.
Intake or study context
U.S. adult RDA: 75 mg/day women; 90 mg/day men.
Food context
Citrus, peppers, kiwi and broccoli.
Cautions & limits
Adult total-intake upper limit: 2,000 mg/day, not a target. High doses can cause gastrointestinal upset; discuss kidney-stone risk or iron overload. Smokers need 35 mg/day more than the RDA.
Nutrient function, intake context and safety sections. General nutrition evidence; not a trial of combination use with this peptide.
Vitamin D
General nutrition
Supports calcium absorption and bone health. Additional supplementation depends on intake and clinical assessment.
Intake or study context
U.S. RDA: 600 IU/day ages 19–70; 800 IU/day over 70.
Food context
Fatty fish and vitamin-D-fortified foods.
Cautions & limits
4,000 IU/day is the adult upper limit, not a routine target. Excess can cause hypercalcemia. Deficiency treatment requires its own plan.
Nutrient function, intake context and safety sections. General nutrition evidence; not a trial of combination use with this peptide.
Magnesium
General nutrition
Supports normal nerve, muscle and enzyme function. This does not establish a sleep or GH-enhancing combination.
Intake or study context
U.S. adult RDA: 310–420 mg/day total, depending on age and sex.
Food context
Nuts, seeds, legumes and whole grains.
Cautions & limits
The adult upper limit is 350 mg/day from supplements and medicines, excluding food. Count elemental magnesium, not compound weight. Kidney impairment increases toxicity risk; mineral products can affect medicine absorption.
Nutrient function, intake context and safety sections. General nutrition evidence; not a trial of combination use with this peptide.
Zinc
General nutrition
Needed for normal immune function and wound healing. A nutrient requirement does not prove added benefit from supplementation when intake is adequate.
Intake or study context
U.S. adult RDA: 8 mg/day women; 11 mg/day men.
Food context
Meat, shellfish, beans and fortified cereals.
Cautions & limits
Adult total-intake upper limit: 40 mg/day. Prolonged high intake can cause copper deficiency. Do not infer that a copper-peptide product prevents this.
Nutrient function, intake context and safety sections. General nutrition evidence; not a trial of combination use with this peptide.
Omega-3 fatty acids
General nutrition
EPA and DHA have studied nutritional and clinical roles; results depend on formulation, dose and population.
Intake or study context
No universal EPA/DHA supplement target for peptide use.
Food context
Oily fish; flax, chia and walnuts supply ALA, a different omega-3.
Cautions & limits
Review anticoagulants and heart-rhythm history. Some long-term 4 g/day trials in cardiovascular-risk populations found more atrial fibrillation. Prescription products are not interchangeable with supplements.
Nutrient function, intake context and safety sections. General nutrition evidence; not a trial of combination use with this peptide.
Vitamin B12
General nutrition
Needed for red blood cells and neurological function. Low intake or impaired absorption may require assessment and treatment.
Intake or study context
U.S. adult RDA: 2.4 mcg/day.
Food context
Animal foods and B12-fortified foods; unfortified plant foods are unreliable sources.
Cautions & limits
Metformin and acid-suppressing medicines can affect B12 status. A food-intake reference is not a treatment dose or a replacement for prescribed injections.
Nutrient function, intake context and safety sections. General nutrition evidence; not a trial of combination use with this peptide.
Vitamin B6
General nutrition
Participates in amino-acid and neurotransmitter metabolism. This does not establish benefit with Semax, Selank or other neuroactive compounds.
Intake or study context
U.S. RDA ages 19–50: 1.3 mg/day.
Food context
Poultry, fish, potatoes and chickpeas.
Cautions & limits
Chronic excess can damage sensory nerves. Check the combined B6 in B-complex, multivitamin and magnesium products. U.S. and European upper limits differ; a limit is not a recommended dose.
Nutrient function, intake context and safety sections. General nutrition evidence; not a trial of combination use with this peptide.
Biotin
General nutrition
Deficiency is uncommon. Evidence for improving hair or nails in otherwise healthy people is limited.
Intake or study context
U.S. adult adequate intake: 30 mcg/day.
Food context
Eggs, fish, meat, nuts and seeds.
Cautions & limits
High-dose biotin can distort laboratory results, including some thyroid and cardiac tests. Tell the clinician and laboratory; they determine whether and how long to withhold it.
Nutrient function, intake context and safety sections. General nutrition evidence; not a trial of combination use with this peptide.
Choline
General nutrition
Needed for cell membranes and acetylcholine. A physiological role is not proof that Alpha-GPC or CDP-choline improves peptide outcomes.
Intake or study context
U.S. adult adequate intake: 425 mg/day women; 550 mg/day men.
Food context
Eggs, meat, fish and soybeans.
Cautions & limits
High intake can cause fishy body odor, sweating and low blood pressure. No routine choline-supplement regimen is selected here.
Nutrient function, intake context and safety sections. General nutrition evidence; not a trial of combination use with this peptide.
Iron
General nutrition
Iron is required for hemoglobin. Deficiency can cause anemia, but iron does not treat every cause of fatigue or anemia.
Intake or study context
Needs vary by age, menstruation and diagnosis; assess before supplementing.
Food context
Meat, seafood, beans and fortified cereals.
Cautions & limits
Excess iron can be harmful, including with iron-overload disorders. Keep iron products away from children. A clinician should interpret blood counts and iron studies.
Nutrient function, intake context and safety sections. General nutrition evidence; not a trial of combination use with this peptide.
Potassium & electrolyte products
General nutrition
Potassium supports normal cell function. Reduced intake or fluid losses need context rather than a standard supplement pack.
Intake or study context
No automatic electrolyte dose or replacement recipe.
Food context
Potatoes, beans, fruit, vegetables and dairy.
Cautions & limits
Kidney disease, ACE inhibitors, ARBs and potassium-sparing diuretics can raise potassium. Salt substitutes and electrolyte powders may add substantial potassium.
Nutrient function, intake context and safety sections. General nutrition evidence; not a trial of combination use with this peptide.
Selenium
General nutrition
Needed for selenoproteins, including those involved in thyroid metabolism. More is not necessarily better.
Intake or study context
U.S. adult RDA: 55 mcg/day.
Food context
Seafood, meat and grains; Brazil-nut content varies widely.
Cautions & limits
Excess can cause hair and nail changes and other toxicity. Do not stack selenium-containing products or assume an immune-peptide regimen requires extra selenium.
Nutrient function, intake context and safety sections. General nutrition evidence; not a trial of combination use with this peptide.
Probiotics
General nutrition
Effects depend on the organism, preparation and condition. A fermented food is not automatically equivalent to a studied probiotic.
Intake or study context
Strain- and condition-specific; no default CFU prescription.
Food context
Some yogurts and fermented foods contain live organisms; check the specific product.
Cautions & limits
Rare serious infections have occurred, especially in severely ill or immunocompromised people. Discuss suitability with the treating team.
Nutrient function, intake context and safety sections. General nutrition evidence; not a trial of combination use with this peptide.
CoQ10 / ubiquinol
Limited, condition-specific evidence
Clinical findings vary by condition; a role in cellular energy is not evidence for extending lifespan or improving a peptide response.
Intake or study context
No established supplement requirement for mitochondrial-peptide use.
Food context
No special food or supplement regimen selected.
Cautions & limits
May interact with warfarin or insulin and may be unsuitable with some cancer treatments.
Benefit limitations and medication interactions; not evidence for a longevity-peptide combination.
Collagen / gelatin
Small human study; indirect
An eight-man crossover trial measured collagen-related biomarkers and effects on engineered ligaments. It did not establish faster clinical healing or benefit with BPC-157 or TB-500.
Intake or study context
Study example, not a prescription: 5 or 15 g vitamin-C-enriched gelatin.
Food context
Gelatin and collagen products vary; the studied preparation is not every commercial product.
Cautions & limits
Biomarker changes cannot establish an injury-rehabilitation regimen. No pre-exercise timing instruction is recommended from this small study.
Shaw et al. · Gelatin and collagen synthesis, 2017
Abstract and figures inspected: randomized crossover study in eight healthy men; biomarker and engineered-ligament outcomes, not clinical injury recovery or peptide coadministration.
Multivitamin / mineral products
General nutrition
A multivitamin can add nutrients when intake is inadequate. It cannot replace a varied diet, and formulations differ.
Intake or study context
Consider a documented dietary gap; no default “one a day” instruction.
Food context
Start by reviewing usual foods and fortified products.
Cautions & limits
Check overlapping ingredients, particularly vitamin D, B6, zinc and iron. Discuss medication interactions and pregnancy-specific needs.
