Supplements for peptide & GLP-1 protocols
The supplements most commonly paired with peptides and GLP-1s — what they're for, typical doses, timing and how they fit alongside your protocol. Educational reference, not medical advice.
Foundation
Creatine monohydrateThe most-researched sports supplement — supports strength, power, and muscle retention, and may aid recovery and cognition. A near-default in this crowd.Electrolyte blendSodium, potassium, and magnesium to replace what you lose through fluids — helps with hydration, energy, and cramps, especially when eating less on a GLP-1.MagnesiumA mineral most people run low on; taken for sleep, muscle relaxation, and constipation relief — it pulls double duty on a GLP-1.MultivitaminBroad micronutrient insurance to cover gaps when you're eating less or restricting food.Omega-3 (fish oil)EPA and DHA fatty acids that support heart, brain, and joint health and help calm inflammation — a staple most diets fall short on.Protein powderA convenient way to hit daily protein targets and protect muscle — especially important on GLP-1s, where suppressed appetite makes protein hard to reach.Vitamin D3The 'sunshine vitamin' most people are low in; supports bone, immune, and mood health. Commonly paired with K2.Vitamin K2Helps direct calcium into your bones rather than your arteries — commonly paired with vitamin D3 for bone and heart health.
Muscle & lean mass
BCAAsThree muscle-building amino acids taken to support recovery — though a complete protein or EAAs generally does the job better.Collagen peptidesThe body's most abundant protein, taken to support skin elasticity, joint comfort, and connective tissue. Pair with vitamin C.Essential amino acids (EAAs)The full set of amino acids your body can't make, taken to drive muscle protein synthesis — especially useful in a calorie deficit.HMBA leucine byproduct taken to protect against muscle breakdown and preserve lean mass while dieting.LeucineThe amino acid that flips the 'build muscle' switch — the key trigger for muscle protein synthesis after eating or training.
GI & digestion
Digestive enzymesEnzymes that help break down food, taken to ease bloating and discomfort when digestion slows — common on GLP-1s.Fiber (psyllium)Soluble fiber that adds bulk and softens stool — the go-to for constipation, the most common GLP-1 complaint. Take with plenty of water.GingerA well-studied natural remedy for nausea and queasiness — handy during GLP-1 dose increases.ProbioticsBeneficial gut bacteria taken to support digestion, regularity, and overall gut tolerance.
Micronutrients
B-complexThe full family of B vitamins for energy metabolism and nervous-system health — insurance when food intake drops.CalciumThe main bone mineral, taken to protect bone density when dairy or food intake falls. Best paired with vitamin D and K2.IronCarries oxygen in your blood; taken to correct fatigue from low iron — but only when bloodwork confirms a deficiency, since excess is harmful.Vitamin B12Essential for energy, nerves, and red blood cells — worth supplementing for vegetarians and older adults, whose levels tend to run low.ZincAn essential mineral for immune function, wound healing, and hormone health. Balance with copper on long-term use.
Metabolic & blood sugar
Alpha-lipoic acid (ALA)A versatile antioxidant taken to support healthy blood sugar and insulin sensitivity, and for nerve health.BerberineA plant compound that helps lower blood sugar and improve lipids — stacked so often it's nicknamed 'nature's Ozempic,' though far milder.ChromiumA trace mineral taken to support how your body handles glucose and to help curb sugar cravings.Green tea extract (EGCG)Concentrated green-tea antioxidants (EGCG) taken for a modest metabolic and fat-oxidation boost.InositolA sugar-like compound that supports insulin sensitivity and mood — especially popular with the PCOS crowd.L-carnitineAn amino acid that helps shuttle fat into cells to be burned for energy — taken to support fat metabolism and exercise recovery.
Joint & tissue repair
BoronA trace mineral taken to support bone health and healthy hormone levels.ChondroitinA cartilage building block taken with glucosamine to support joint comfort and mobility.CopperA trace mineral needed for tissue and blood-vessel repair; balances zinc and pairs naturally with copper peptides like GHK-Cu.GlucosamineA cartilage building block widely taken to support joint comfort and slow wear-and-tear aches.Hyaluronic acidA moisture-binding molecule taken for joint cushioning and skin hydration.MSMA sulfur compound taken for joint comfort and to help calm exercise-related inflammation.Vitamin CAn antioxidant and essential cofactor for building collagen — almost always paired with collagen for skin, joint, and tissue support.
Sleep & recovery
ApigeninA calming plant compound (found in chamomile) taken before bed to help wind down and improve sleep.GABAA calming brain chemical taken as a supplement to promote relaxation and ease into sleep.GlycineAn amino acid taken before bed to lower body temperature and improve sleep quality and next-day freshness.L-theanineA calming amino acid from tea that takes the edge off without sedation — the classic partner to caffeine for smooth, focused energy.MelatoninYour body's natural sleep-timing hormone, taken in small doses to fall asleep faster or reset your clock after travel.ZMAA zinc, magnesium, and B6 blend taken at night to support recovery, sleep, and healthy hormone levels.
Skin & anti-aging
AstaxanthinA powerful antioxidant pigment taken for skin resilience (including sun tolerance) and eye health.BiotinA B vitamin popularly taken to support hair, skin, and nail health.ResveratrolA plant antioxidant (found in red wine) taken for anti-aging and cardiovascular interest, targeting cellular longevity pathways.
Liver & antioxidant
CholineAn essential nutrient that helps the liver process fat and supports brain and cell health.GlutathioneThe body's 'master antioxidant,' taken to support detoxification, skin, and cellular defense against oxidative stress.Milk thistleA herbal extract (silymarin) long used to support and protect liver function.NACA precursor your body uses to make glutathione — taken for liver support, antioxidant defense, and respiratory health.TUDCAA bile acid taken to support liver and bile-flow health — popular in the peptide- and steroid-stacking community for liver protection.
Cardiovascular & longevity
CoQ10An antioxidant your cells use to make energy; taken to support heart health and energy, and often to offset the muscle aches some people get from statins.L-arginineAn amino acid your body turns into nitric oxide, which relaxes blood vessels — taken for blood flow and circulation, though citrulline is often better absorbed.L-citrullineAn amino acid that raises nitric oxide to widen blood vessels and improve blood flow — popular pre-workout for pumps and endurance.NattokinaseAn enzyme from fermented soy taken to support healthy circulation and help the body break down clots.TaurineAn amino acid involved in heart, muscle, and nervous-system function, taken for cardiovascular support and general resilience.
Cognitive & nootropic
Alpha-GPCA highly absorbable source of choline taken for focus and memory, and sometimes to support a natural growth-hormone bump around exercise.CaffeineThe everyday stimulant for alertness and energy — classically paired with L-theanine to keep the focus without the jitters.L-tyrosineAn amino acid that helps replenish focus-related brain chemicals under stress or sleep deprivation, taken to hold attention when you're taxed.Lion's maneA mushroom extract studied for nerve growth and long-term brain health — taken for focus and memory, with effects that build over time rather than instantly.
