Iron is an essential mineral; without adequate levels, the body cannot produce sufficient haemoglobin, which carries oxygen to tissues.
Iron is an essential mineral; without adequate levels, the body cannot produce sufficient haemoglobin, which carries oxygen to tissues. This combination is well-established in nutritional medicine and is a common clinical recommendation for those supplementing iron.
Take 1 capsule daily, as directed on the packaging. Iron is generally better tolerated when taken with food, which may also reduce the risk of nausea. The vitamin C in the formula assists absorption without needing an additional supplement.
Iron-C by Pure Encapsulations is a daily iron supplement formulated alongside vitamin C to support iron absorption and red blood cell production. Iron is an essential mineral; without adequate levels, the body cannot produce sufficient haemoglobin, which carries oxygen to tissues. Vitamin C, when taken alongside iron, converts ferric iron to the more bioavailable ferrous form, meaningfully improving uptake in the gut. This combination is well-established in nutritional medicine and is a common clinical recommendation for those supplementing iron.
This supplement suits people with confirmed low ferritin or iron-deficiency anaemia - ideally identified through a blood test rather than guesswork. It is particularly relevant for women of reproductive age with heavy menstrual cycles, individuals following plant-based diets where dietary iron is predominantly non-haem and less readily absorbed, and anyone recovering from iron-depleting periods such as pregnancy or sustained endurance training.
Pure Encapsulations is a brand with a longstanding clinical reputation, formulating to professional-grade standards with minimal unnecessary excipients. Their products are a regular choice among practitioners who want a clean-label option they can recommend with confidence. As always, iron supplementation is best guided by blood results - too much iron carries its own risks, and this is not a supplement to take speculatively long-term without monitoring.

Sign inWe strongly recommend one. Iron deficiency and iron-deficiency anaemia are diagnosed via blood markers including ferritin and haemoglobin. Taking iron supplements without confirmed deficiency is not advisable long-term, as excess iron accumulates and can cause harm.
Vitamin C converts dietary iron from its ferric form to the more soluble ferrous form, which the gut absorbs far more readily. This is particularly relevant for non-haem iron (the form found in plant foods and most supplements), which is inherently less bioavailable than haem iron from animal sources.
Those with confirmed low ferritin or iron-deficiency anaemia, women with heavy periods, people following vegan or vegetarian diets, pregnant or recently postpartum women, and athletes in heavy training blocks who may deplete iron through sweat, foot-strike haemolysis, or increased red blood cell turnover.
Iron supplements can cause nausea, constipation, or dark stools in some people. Taking the capsule with food may reduce gastrointestinal discomfort. If side effects persist, speak to a clinician — there may be a more suitable form or dose for your situation.
Iron can interact with certain medications, including some thyroid drugs, antibiotics, and antacids, by reducing their absorption. Space iron away from these by at least two hours. If you are on prescription medication, check with your GP or pharmacist before starting iron supplementation.
Overall

Been supplementing iron for about three months after a blood test flagged low ferritin. This one was recommended by my GP and I can see why — no constipation issues that I had with the previous brand, and my last blood test showed a meaningful improvement. The vitamin C inclusion makes a real difference I think.

I'm plant-based and my iron has always been on the lower end. Switched to this after my nutritionist suggested it. Six weeks in and I feel less foggy in the afternoons — can't attribute it purely to this but it's the only thing I changed. Appreciate that the ingredient list is minimal.

Does what it says. Levels came up, no stomach upset. Would buy again.

Started these during marathon training after a blood panel showed my ferritin had tanked. Took them consistently for ten weeks alongside my meals and the retest came back in a much better range. Glad I didn't just grab something off a pharmacy shelf — this feels like a proper clinical product.

Iron levels have definitely improved since I started taking these — my GP was happy with the three-month retest. My only gripe is the capsule size, they're on the bigger side and I do sometimes struggle to swallow them. Minor issue but worth knowing if that's a concern for you.

My midwife suggested iron supplementation after my levels dropped following birth. I did some research and landed on this one specifically because of the added vitamin C — I'd read that it really does help with absorption. Two months in and I have noticeably more energy during the day, which with a newborn is very welcome.
