Dr Daily collagen, gluta and vitamin C review

At around ₱389 as of August 24, 2026, with 100mg each of collagen, L-glutathione and vitamin C per capsule. Naming three amounts is more than most of this shelf does, and one of them needs context.

A hundred milligrams against the studied range

Oral collagen has a real evidence base. Systematic reviews of randomised trials find measurable improvements in skin hydration and elasticity, which is more than can be said for most beauty supplements.

The doses those trials used are the part that matters. The most common dose is around 4g a day, the median about 3.5g, and the full range across studies runs from roughly 250mg up to 10g.

This capsule carries 100mg. That is below the smallest dose in that range, and around a fortieth of the typical one.

So the honest position is not that the ingredient does not work. It is that this amount has no trial behind it, and that anyone buying collagen for the researched effect is not getting the researched amount.

The vitamin C is doing real work

Easy to overlook next to the headline ingredients, and it is the best-supported thing in the capsule.

Your body makes its own collagen continuously, and vitamin C is required for that process. It is not a marketing pairing; without adequate vitamin C the enzymes that build collagen cannot function, which is what scurvy is.

At 100mg it is a sensible daily amount for that purpose, comfortably above what is needed to avoid deficiency.

Glutathione, briefly

A hundred milligrams of oral L-glutathione is at the low end of what skin-lightening products use, and oral glutathione’s absorption is itself debated, since it is a peptide that digestion breaks down.

If skin tone is the reason for the purchase, that is worth knowing before spending, and it is worth knowing that the Philippine FDA has repeatedly warned about injectable glutathione specifically. Oral is the safer format and the less potent one.

What to look for instead

If collagen is genuinely what you want, look for a product that states grams rather than milligrams and aims at 2.5g to 10g a day, and expect to take it for at least eight to twelve weeks, which is the timescale the trials ran on.

The Goodies Glow collagen gummies 60-count publishes 2,000mg a day, the highest stated dose on this page, which is still under the typical trial amount and an order of magnitude past this one.

Who should buy Dr Daily

Buy this if you want a convenient one-capsule blend and you are treating the collagen as a small addition rather than the point.

Skip it if you are buying collagen for what the research shows, where the dose is what you are paying for.

Higher-dose alternatives
