Vitamins and supplements people pair with peptides: the honest list
Electrolytes, protein, fibre, the minerals that go missing on small meals, and which tubs to ask a pharmacist about first. What each one is, not what it does.
Last reviewed · written by PepPrep · not medical advice
This is the section people asked for most, so here is the straight version. Everything on the Vitamins & Supplements shelf is an ordinary pharmacy or gym product. None of it treats, prevents or "boosts" anything, and we describe each one as what it is and what people buy it for, nothing more. If you take any medicine at all, a pharmacist is the right person to ask before adding a tub. That said, there is a sensible order to it.
Start with the boring three
Almost everyone who is eating less than they used to ends up short on the same things: fluid and salts, protein, and fibre. That is why electrolytes, a protein powder and a fibre powder sit at the top of the shelf. A multivitamin is the fourth, because small plates carry fewer vitamins whatever is on them. If you buy nothing else, buy those.
Rough days
Two products exist for the day food will not stay down: ginger (chews or capsules) and oral rehydration salts. ORS is not a sports drink: the sugar is there on purpose, in a ratio that makes the salts absorb faster, which is why pharmacies sell it and gyms do not. Keep two sachets in the travel bag. If you cannot keep fluids down for a full day, that is a doctor question, not a sachet question.
Protein without the milkshake
A thick shake is the last thing some people want. The shelf now covers the alternatives: clear whey that drinks like juice, bone broth protein for a savoury mug, plant protein if dairy sits heavy, casein for a slow evening one, and EAA powder when even a light shake is too much. A complete meal shake is the answer to "I forgot to eat again". Pick one or two; nobody needs all six.
Minerals: the ones that go missing
Magnesium, potassium, calcium, zinc and iron are the five people ask about. Two cautions worth repeating from the product pages: potassium is the one to check with a pharmacist if you take a blood-pressure or water tablet, and iron is the one worth a blood test first, because too much is stored, not flushed. Calcium citrate rather than carbonate, because citrate does not need a full stomach to absorb.
The vitamins
A B complex covers the eight B vitamins that come mainly from a full plate; B12 and B6 are on the shelf on their own for people who only want one. D3 with K2 is the one most adults in northern countries are short on regardless of diet. Vitamin C is cheap and is what collagen is built with. One rule for all of them: if you take a multivitamin as well, add the numbers up before you double anything.
Recovery-shelf regulars
Collagen, glycine, omega-3, curcumin and glucosamine are the ones people on anything for recovery already own. Creatine, HMB, L-carnitine and taurine are the gym-shelf set for people trying to lose fat without losing muscle. Give any of these two to three months before deciding; none of them do anything in a week.
Hair, and the one test-day rule
Hair shedding a few months into fast weight loss is common and usually settles on its own; protein and iron matter more for it than anything in a gummy. If you do take biotin, know that high doses interfere with several blood tests, including thyroid and heart tests. Stop it three days before any blood draw and tell the nurse.
The ones to ask about first
Berberine and CoQ10 are on the shelf because people ask for them by name. Berberine interacts with a long list of medicines, including several for blood sugar and blood pressure, and it is not for pregnancy. CoQ10 is worth a mention if you take a blood thinner. Both are honest supplements with an honest warning.
Make it a habit, not a shelf
A weekly AM/PM organiser filled on Sunday is what turns a row of tubs into something that actually gets taken. Put the with-food ones (zinc, iron, curcumin, CoQ10) in the morning slot next to breakfast and the evening ones (magnesium, glycine, casein) on the other side. Keep iron away from coffee and calcium by a couple of hours, and keep every tub out of children's reach.
