Asta Plus Immunity Multivitamin review: astaxanthin PH

Asta Plus builds its formula around astaxanthin, an antioxidant almost nothing else in this category carries, and publishes a long ingredient list to go with it. Whether the lead ingredient earns its billing is the interesting question.

Astaxanthin, lutein, and lycopene, on top of a full multivitamin

The published list runs to astaxanthin, lutein, and lycopene alongside calcium, ascorbic acid, potassium, magnesium, niacin, vitamin E, zinc, iron, manganese, riboflavin, vitamin B1, B6, vitamin A, copper, folic acid, iodine, biotin, selenium, vitamin D3, and B12.

The three carotenoids at the front are the differentiator. Astaxanthin is the pigment that makes salmon and shrimp pink and is sold widely as an antioxidant; lutein is the one associated with eye health; lycopene comes from tomatoes. Most multivitamins in this category carry none of them, and Centrum carries lutein and lycopene in small stated amounts.

Behind them sits a genuinely broad vitamin and mineral base, close to two dozen entries. This isn’t a narrow antioxidant capsule with a few vitamins bolted on.

The evidence behind the lead ingredient is thinner than for the rest

Worth being straight about the difference in footing.

Vitamin C, vitamin D, zinc, iron and the B vitamins have decades of established science behind what they do and how much you need. Astaxanthin’s immune benefits are a more recent and less settled area of research. It isn’t a fringe ingredient, but the confidence you can have in it is not the same as the confidence you can have in vitamin D, and a formula that leads with it is leading with its least established component.

The ingredient amounts aren’t published either, so you can’t tell whether the astaxanthin is a studied dose or a garnish, which matters most for exactly the ingredient you’d be paying extra for.

What it costs, and what the listing doesn’t say

At around ₱785 as of August 31, 2026, the listing doesn’t state a capsule count, so an honest cost per day can’t be worked out from what’s published. Check the count on the listing and divide before you compare it with anything else here.

It’s FDA-approved and formulated by a Philippine nutraceutical company, sells through Nutriplus, and holds a 4.9 Shopee rating across 640 ratings with 2K+ sold.

These are food supplements, not medicines. “Immunity booster” is marketing language: no supplement boosts immunity in the way the phrase implies, and the honest version is that adequate nutrition supports normal immune function. Our vitamins buying guide covers what a label can reasonably claim.

Who the antioxidant-forward formula suits

Buy this if you specifically want astaxanthin, lutein and lycopene in the same capsule as a broad multivitamin rather than buying them separately, and you’re comfortable with an unquantified list from an FDA-approved local maker.

Skip it if you want established nutrients at published amounts, where a fully itemized tablet does more for your money.
