Vitamins and minerals

Vitamins and minerals are the nutrients your body needs in small amounts and mostly cannot make, so they come from diet. This category covers them individually and in combination, along with the oils, herbals and targeted formulas built around them.

The principle worth carrying through the whole category is that supplements fill gaps rather than replace food, and more is not better. Fat soluble vitamins, A, D, E and K, are stored rather than excreted, and several minerals have a narrow margin between enough and too much. The Nutrient Reference Values publish both recommended intakes and upper levels for exactly this reason.

How they are usually used

Most are once daily with food, which helps absorption of the fat soluble vitamins and reduces stomach upset. Iron is the main exception, absorbing better away from food, tea, coffee and calcium. Supplements are not a substitute for medical advice. If you are pregnant or breastfeeding, take prescription medication, or are managing a health condition, check with your doctor or pharmacist before starting something new.

Compare the range

TypeUsually chosen forWhat makes it different
Letter Vitamins A known shortfall in one vitamin Individual vitamins at a meaningful dose rather than a little of everything. Watch upper levels on A, D, E and K.
Minerals Iron, calcium, zinc and the rest Minerals compete for absorption, so spacing matters. Iron in particular is worth testing before taking.
Fish & Nutritional Oils Omega-3 intake Read the combined EPA and DHA figure, not the capsule weight. Algae oil is the vegan equivalent.
Herbals Plant based preparations Standardised extracts are more predictable. Several interact with prescription medicines, so check first.
Immune Support Vitamin C, zinc and vitamin D Works by correcting shortfalls rather than boosting. Most useful through winter or where levels are low.
Joint & Bone Cartilage comfort and bone density Calcium and vitamin D for bone are well established. Glucosamine and chondroitin are more mixed.
Pain & Inflammation Turmeric, omega-3 and boswellia Gradual, over weeks. Not a substitute for pain relief medication or for seeing a doctor.
Heart Health Omega-3, CoQ10 and plant sterols Supporting role only. Diet, activity, blood pressure and cholesterol management do the heavy lifting.
Brain Health Focus now, or nutrients long term Two different timescales in one aisle. Focus ingredients act today; nutrients and herbals take months.

Frequently asked questions

Can I take too many vitamins?

Yes, particularly A, D, E and K, which are stored in the body rather than excreted. The Nutrient Reference Values publish upper levels for this reason. Water soluble vitamins are more forgiving, though sustained high dose B6 can cause nerve problems.

Should I take a multivitamin or individual vitamins?

A multivitamin gives broad low dose cover for small gaps. An individual vitamin lets you address a known shortfall at a proper dose. If a blood test has shown you are low in something specific, the single vitamin is the right tool.

Do minerals interfere with each other?

Yes. Calcium reduces iron absorption, high dose zinc depletes copper over time, and large doses of one mineral can crowd out another using the same transport. Spacing doses or using a balanced product avoids most of it.

How do I know what I am short of?

A blood test through your doctor rather than guessing from symptoms. Fatigue, which sends most people to this aisle, has many possible causes, and taking something on spec can mask a problem worth investigating.

Is it better to get nutrients from food?

Yes, where you can. Whole foods bring fibre and a range of compounds a tablet does not, and the Australian Dietary Guidelines are built on that. Supplements cover specific shortfalls rather than replacing the food groups.
