$2.67 per gram of IgG · $0.67 per gram of powder

Net weight is on the front label (1 oz = 28.35 g). IgG is usually in the Supplement Facts panel; if it is missing, the brand has not told you.

Worked example

A 120 g jar at $79.99 costs $0.67 per gram. If the label says 25% IgG, each gram contains 0.25 g of IgG, so a gram of IgG costs $0.67 ÷ 0.25 = $2.67.

Converting labels

Net wt in ouncesgrams = oz × 28.35
IgG in mg per servingIgG % = mg ÷ (serving g × 1000) × 100
Capsulesgrams = capsules × mg per capsule ÷ 1000

Compare your result with the nine-brand table.
