Choosing between mastic gum and elemental zinc
Mastic gum vs elemental zinc is not a like for like comparison, because one is a resin sold by weight and the other is a mineral measured in elemental milligrams. That difference is why cost per bottle tells you nothing useful and cost per absorbed milligram tells you nearly everything.
What mastic gum and elemental zinc declare
A zinc product lists elemental zinc on the nutrient row, often 15 mg, with a percent daily value beside it so you can compare across forms without knowing anything about chemistry. A mastic gum product lists a resin weight, and the resin is a mixture of compounds rather than a single measured nutrient.
One label lets you do arithmetic. The other asks you to trust the source material, which is a legitimate way to buy something but a poor basis for comparing it against a mineral tablet.
Absorption, without the hand waving
Zinc absorption depends on the form and on what else is in your stomach. Zinc citrate and picolinate are chelates and behave differently from zinc oxide, and copper competes for the same pathway, which is why the zinc and copper labels belong in the same glance.
Mastic gum is not absorbed as a nutrient in the way a mineral is. It is chewed or swallowed as a resin, and the question people are usually asking is about the mouth and stomach environment rather than about serum levels. That is a different question, and it deserves a different product rather than a dose comparison.
Doing the cost comparison properly
For the zinc side, work out elemental milligrams per serving, servings per bottle, and cost per day. At 15 mg per capsule, 1 capsule a day, 120 capsules for $13.20, that is $0.11 a day. Now you have a real number.

For the gum side, work out grams per serving and cost per day at your actual rate. The two figures are not in the same unit and cannot be ranked against each other. What you can do is decide which question you are trying to answer, then buy the product that answers it.
Switching between them
There is no washout period, so there is nothing to taper. Finish one and start the other the following day if you decide the other is what you wanted. What I would not do is run both and hope the combination tells you which one mattered, because it will not.
One product at a time, 30 days each, one note. That protocol took me 2 months once and gave me a real answer. Buying both at once took 2 years and gave me a tidier cupboard.
Decide the question first, then compare in the same unit. Everything else is packaging.
What I'd tell someone standing in the aisle
Ask yourself what you're trying to do. If it's about a mineral figure you can track, buy the zinc and write the 4 fields down. If it's about the mouth and stomach environment, the resin is the product for that job, and the zinc tablet isn't a substitute at any dose.

Neither one is the wrong answer. Comparing them on price is the wrong question, and it's the one the shelf layout encourages, because putting 2 products side by side implies they compete.
They don't. Pick the job, then pick the product, then check the panel. That order solves it every time.
Frequently asked questions
Is mastic gum the same as elemental zinc?Show answerHide answer
No. mastic gum and elemental zinc differ in how much of the nutrient survives digestion, which changes the dose you need.
Can I switch straight over?Show answerHide answer
Yes. There is no washout period, so you finish one and start the other the next day.
Which one is the better value?Show answerHide answer
Compare cost per absorbed milligram, not cost per bottle, before deciding.
