Every mother I know who has breastfed has, at some point, googled “how to increase milk supply” at two in the morning, phone brightness turned all the way down, baby fussing at a breast that suddenly feels inadequate. I did it too. And what I found was a wall of advice, some of it excellent, a lot of it repeated so often it’s assumed to be fact, with almost nothing separating the two.
So let’s separate them.
The thing that actually moves the needle: demand
Your supply is a demand-driven system, not a fixed tank you’re slowly depleting. The more effectively and frequently milk is removed from your breast, by your baby feeding well, or by pumping, the more your body produces. This single mechanism explains almost everything else on this list, so it’s worth understanding before anything else.
This means the single most effective way to increase supply, ahead of any food, drink, or supplement, is to feed more often and to make sure each feed is effectively removing milk (which comes back to the latch, see our deep latch guide if that’s uncertain). Adding a pumping session after feeds for a few days, particularly first thing in the morning when supply is naturally highest, sends the same demand signal and can meaningfully increase output within days.
What genuinely helps
Hydration, especially in Mauritius heat where insensible water loss through sweat is significant even without noticing it. Aim for roughly 3 litres of fluid across the day. This won’t dramatically boost an already-adequate supply, but genuine dehydration can suppress it, so this is a floor to maintain, not a lever to pull harder on.
Adequate calories, not restriction. Breastfeeding requires roughly 500 additional calories a day above your pre-pregnancy intake. Severe caloric restriction, the kind some mothers attempt for postpartum weight loss, can genuinely reduce supply. This is not the moment for a strict diet.
Galactagogues with an actual evidence base: moringa (bred mouroum) has real nutritional grounding: it’s dense in iron, calcium, vitamin A, and complete protein, exactly the nutrients your body is drawing on heavily during lactation, and there’s a growing body of research supporting its traditional use across the Indian Ocean region as nutritional support during breastfeeding. Fenugreek has similarly wide traditional use, though it affects people differently and isn’t suitable for everyone, check with your doctor if you have thyroid issues or are diabetic, as fenugreek can affect blood sugar. Oats are gentler and lower-risk, and while the mechanism isn’t fully understood, many mothers report a noticeable difference. None of these are medicine. None of them guarantee an outcome. What they offer is solid nutritional support layered on top of the thing that actually drives supply, which is demand.
Rest and stress reduction, to whatever degree is realistically available to you with a newborn (which, let’s be honest, is limited). Chronic stress and severe sleep deprivation suppress prolactin, the hormone driving milk production. This isn’t “just relax,” which is useless advice to anyone with a baby. It’s closer to: protect what small pockets of rest you can, because they’re doing physiological work, not just feeling nice.
What’s mostly myth, or at least oversold
Specific “milk-boosting” foods eaten once: a single bowl of oats or one lactation cookie will not measurably change your supply that day. The foods above help as part of a consistently adequate diet over time, not as an emergency lever.
Beer or dark beer specifically: an old wives’ tale with no real supporting evidence; the barley in beer has a small theoretical galactagogue property, but the alcohol works against you, and there are better ways to get barley’s benefit without it.
Drinking excessive amounts of water beyond thirst: more water than your body needs doesn’t create more milk than your body needs; it mostly creates more trips to the bathroom. Hydrate to thirst, not to excess.
Pumping obsessively “just in case” in the early weeks when supply is still establishing and feeding is going well, this can actually create oversupply and the discomfort that comes with it, rather than helping anything.
The thing worth saying plainly
If you’ve tried the things that genuinely help and supply still feels low, the most useful next step isn’t another supplement, it’s an assessment. What looks like low supply from the outside is very often a latch issue reducing transfer efficiency, or completely normal newborn feeding frequency being misread as a problem, or the lingering effect of early supplementation that quietly reduced the demand signal weeks ago. A lactation consultant can tell the difference between “genuinely low supply” and “looks low but isn’t” in a single visit, and the two have very different fixes.
