Aged garlic capsules usually report 300 to 600 mg per serving, while the same panel might list 60 mcg of a vitamin fraction, and a microgram is one thousandth of a milligram, so 60 mcg is 0.06 mg.
Milligrams and micrograms on one label
Both units describe weight. A milligram is a thousandth of a gram and a microgram is a millionth, which puts three decimal places between them. When one line says 600 mg and the next says 200 mcg, the second number isn't small because the ingredient is weak. It's small because the unit is tiny.
Convert both to milligrams before you compare two bottles. That's the whole job. Once every figure sits in the same unit, the arithmetic is ordinary division.
The IU problem with aged garlic capsules
IU stands for international unit, and it measures biological activity rather than mass. Vitamin D and vitamin E are the two most common places you'll meet it, and neither converts to milligrams with one fixed number. Vitamin D is 0.025 mcg per IU. Vitamin E depends on the form, so 1 mg of natural alpha tocopherol is about 1.49 IU and 1 mg of the synthetic form is 1 IU.
If a garlic product lists vitamin E in IU and a competitor lists it in mg, you're comparing two different scales. Pick the unit the cheaper bottle uses, convert the other one, then divide by price per serving.
Comparing the cost of a day, not the size of a bottle
This is where most mistakes happen. A 90 count bottle has 45 doses when you take two. A 120 count bottle has 120 when you take one. The first looks like more product on the shelf and gives you a third of the days.
Work out cost per day for each candidate before you look at the price tag. The 90 count aged garlic at $26.99 runs 90 cents a day at 2 gummies, and a 60 count bottle at $19.99 taken two at a time runs 67 cents a day. The cheaper bottle is the smaller bottle.
You can do that sum on a phone in about 20 seconds and it settles most of the argument in this category.
Where the numbers stop helping
Unit conversion tells you what you're paying for. It doesn't tell you whether the extract is standardised to a marker compound, and standardisation is the part that makes two 600 mg products comparable at all. Aged garlic extract is usually standardised for S-allyl cysteine, which is the water soluble fraction that survives the aging process.
One limit worth naming. A higher milligram figure on the front of a bottle is not evidence of a better product, and no conversion corrects for a formula that was never tested at that dose in people. The published human work in this category used specific doses of specific preparations, and a label that happens to match the milligram number can still be a different material.
I'll take 300 mg standardised to a stated marker over 1,000 mg with no marker listed, every time. You should too.
A worked example with a bundle
Say a two bottle set is $46 for 180 total gummies and a single bottle is $26.99 for 90. Divide by the 2 gummies you take daily and the set is 90 days at 51 cents a day, against 90 days at 60 cents buying singles. That's a 15 percent saving for buying the same product twice, and the conversion only took the dose size to get there.
Check the labels on the bundle page before you assume the discount applies to the same count. Sets sometimes pair a 90 count with a 60 count and call it a value.
What the panel should show you
Look for per dose, per capsule and the count, in that order. A panel that lists only per capsule forces you to multiply, and one that lists only per dose hides the count problem. The third line, how many doses the container holds, is the one most often missing and the one that decides your daily cost.
Bring a calculator. Two minutes of arithmetic beats a year of guessing.
Frequently asked questions
What is the difference between mg and mcg?Show answerHide answer
A microgram is a thousandth of a milligram, so the number looks much larger.
Why do some labels use IU?Show answerHide answer
Older units like IU describe biological activity rather than weight, and 0.025 mcg of vitamin D equals 1 IU.
How do I compare across units?Show answerHide answer
Convert to the same unit first, then compare per serving.
