Rule One Women's Train Daily

Over 40 active ingredients including 25 vitamins and minerals, in a two-tablet daily serving. Zero calories, zero sugars, zero banned substances.

The differences from the men's version are real and worth understanding, because "for women" on a multivitamin is usually just marketing.

Iron is the actual difference, and it matters

This is the single most important distinction between a men's and a women's multivitamin, and it is not cosmetic.

Menstruating women lose iron every month. That ongoing loss means requirements are substantially higher than for men — roughly 18mg daily against 8mg — and iron deficiency is one of the most common nutritional deficiencies worldwide, disproportionately affecting women of reproductive age.

Iron carries oxygen in the blood as part of haemoglobin. Low iron shows up as fatigue, breathlessness during exercise, and poor training capacity — symptoms that are easy to attribute to poor sleep or overtraining when the cause is nutritional.

This is also why men's multivitamins usually contain no iron at all. Men have no routine iron losses, and iron accumulates rather than being readily excreted. That is not an oversight in the men's formula; it is deliberate.

Which leads to the important caution below.

⚠ Iron warnings that are not boilerplate

Accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under six. That warning appears on the label because it is true. Keep this out of reach of children, and treat it with the same care you would a medication.

Do not take an iron-containing multivitamin without knowing you need iron. Post-menopausal women, and anyone with haemochromatosis or another iron-overload condition, should not supplement iron routinely. If you are not menstruating, an iron-free multivitamin may be the more appropriate choice — Men's Train Daily is not sex-specific in any meaningful way beyond the iron, and plenty of women take it for exactly that reason.

A simple blood test tells you your iron status. If you are unsure, ask your doctor rather than guessing. That is the honest answer and it applies in both directions.

What else is in it

25 vitamins and minerals, including 200% of the daily value for vitamin D3
Folate — essential for cell division and DNA synthesis, and the reason it is emphasised in women's formulas, since requirements rise substantially in early pregnancy, often before pregnancy is known
Calcium — women have a higher lifetime risk of bone density loss, making intake more consequential
Cranberry — the proanthocyanidins in cranberry are studied for urinary tract support
Isoflavones — plant compounds with a weak structural similarity to estrogen
Silica — included for hair, skin and nails
Antioxidant vitamins A, C and E, a carotenoid complex, superfood concentrates and botanical extracts

Frequently asked questions

Why does the women's multivitamin contain iron and the men's does not?
Menstruating women lose iron monthly, so requirements are roughly 18mg daily against 8mg for men. Men have no routine losses and iron accumulates rather than being readily excreted, so leaving it out of a men's formula is deliberate.

Should I take it if I am post-menopausal?
Possibly not. Without monthly losses, routine iron supplementation is not usually appropriate. The men's version is iron-free and otherwise comparable. Ask your doctor if you are unsure.

Can I take it while pregnant?
No. Rule One states it is not for women who are pregnant, trying to conceive, or nursing. Prenatal formulations differ meaningfully — speak to your doctor.

Why not with coffee?
Tannins in tea and coffee inhibit iron absorption. Take it with a meal instead.

Does vitamin C help?
Yes, it improves iron absorption and is included in the formula. Calcium does the opposite, so space any separate calcium supplement a couple of hours apart.

Why is my urine bright yellow?
Riboflavin. Water-soluble, dosed above the daily value, and the excess is excreted. Harmless.

Can men take the women's version?
They can, but the iron is not needed and accumulates over time. The men's version is the better fit.

How is it different from a supermarket multivitamin?
Higher potencies plus superfood concentrates, botanical extracts, isoflavones and silica. A two-tablet serving also allows more material than a single one-a-day physically can.
