Cheonsa Glutathione + Vitamin C + Zinc review: immune stack

Cheonsa is the only listing in this category that puts zinc in the capsule, which shifts it slightly away from a pure skin supplement and toward general immune support.

Glutathione, vitamin C, and zinc

The capsule combines glutathione, vitamin C, and zinc, stated as a 500mg combined formula. Vitamin C alongside glutathione is standard in this category. Zinc is not, and it’s the reason to consider this over its rivals.

Zinc and vitamin C are the two supplements Filipino households most often reach for when someone is run down, so having them in the same capsule as the glutathione makes this a sensible choice if you want one daily capsule doing more than one job.

The 500mg is a total, not a dose

The number on the label covers all three ingredients together. It is not 500mg of glutathione.

That distinction is the single most useful thing to understand when shopping this category, and Cheonsa’s label is a clean example of it. A combined total could be 400mg glutathione and 100mg of the other two, or the reverse, and nothing on the listing tells you which. Compare it against a capsule stating 200mg of glutathione specifically and you are not comparing like with like, even though 500 looks like the bigger number. Our glutathione supplement buying guide explains what to look for instead.

The same gap applies to the zinc. Without a figure you can’t check it against a daily requirement, which is what an immune-support claim would need.

Two months per bottle, and what a day costs

At around ₱1,900 as of August 31, 2026 for 60 capsules, that’s about ₱32 a day, one of the lower daily costs in this category. The 60-count is part of why: most rivals here sell 30 capsules, so this bottle is two months rather than one, which means fewer reorders and less chance of a gap in the routine.

It sells through Watsons’ official Shopee Mall store and holds a 4.9 Shopee rating, though across only 35 ratings. That’s a thin base, so treat the score as encouraging rather than established.

What the label can claim

This is a food supplement rather than a medicine, marketed for skin and immune support. We can confirm the ingredients named, the count, and the price. We can’t confirm how much of each you get, and no listing in this category can promise you a change in skin tone.

Who the zinc addition suits

Buy this if you want your glutathione capsule to double as a vitamin C and zinc top-up, you prefer buying through Watsons, and the two-month bottle appeals. As a general daily capsule at a low cost per day, it’s easy to live with.

Skip it if you’re comparing formulas on disclosed glutathione content, because a combined total doesn’t let you do that, and skip it if you already take a separate zinc or vitamin C supplement.
