Vitamin C + Zinc: comparing a two nutrient tablet

How to read a combined vitamin C and zinc panel, including elemental zinc, named compounds and pack comparisons.

Read the rows, not the product name

A combination name tells you what is present. The panel tells you how much, one row per nutrient, each with its own unit and its own reference percentage.

Two packs with the same name can state very different pairs of amounts, so the name is where comparison starts and never where it ends.

Zinc on a panel is elemental zinc

Zinc is supplied as a compound: zinc citrate, zinc gluconate, zinc oxide, zinc bisglycinate and others. The ingredients list names the compound used.

The panel states elemental zinc, which is the metal content of that compound. The compound mass is always the larger figure, so reading it as the nutrient amount overstates the pack.

Elemental figure lives in the nutrition panel
Compare elemental against elemental, never compound against elemental

The vitamin C source is named too

The same distinction applies on the vitamin C row. Ascorbic acid and the ascorbate salts are different compounds, and a salt carries a mineral with it.

If the pack uses an ascorbate salt, the mineral may appear as an extra row or in the ingredients, which is worth noticing when you are already buying a mineral in the same tablet.

One tablet, two percentages

Each nutrient has its own labelling reference value, so the two percentages in this panel are measured against different baselines.

That is normal. It also means a high percentage in one row says nothing at all about the other row.

Combination against singles

To compare this 60 tablet pack with buying Vitamin C and Zinc separately, line up three things: pack price, unit count, and the stated amount in each panel row.

Stop at pack level unless you have read the portion on each label, rather than inventing a daily cost.
