Inside this capsule
This capsule
Vitamin C
Buffered ascorbate · 1000 mg
One ingredient. The dose on the label is the dose in your hand, and the lot number traces it back to one supplier: DSM (Quali-C).
A typical blend capsule
ingredient?dose?ingredient?dose?ingredient?dose?ingredient?dose?ingredient?dose?ingredient?…
“Proprietary blend, 1,200 mg” — many names, one number, no way to know how much of anything you took, or what competes with what inside.
On the evidence
Vitamin C's contribution to normal immune-system function is an authorised nutrient function.

Repeated randomised human trials
Every ingredient in the catalogue carries one of these three grades — including the ones we grade down. A scale you never see the bottom of is not a scale.
When you’d notice
Set by how long the body pool takes to refill
From 1 week → settles by 4 weeks
day 11w2w4w8w12w26w
Plasma fills quickly and then stops rising; more does not fill it further.
Source: NIH ODS — plasma saturates within days to weeks at normal supplemental doses
Take it with / keep it apart
Single ingredients let timing work for you — blends lock everything into one swallow.
◎ Pairs well with Iron
Ascorbate reduces iron to its better-absorbed form and counters inhibitors in the same meal. → Take them together — same meal, on purpose. (NIH ODS Iron Fact Sheet (enhancers of non-heme iron))

- ★★★★★Good, shipping takes patience
Product quality feels premium and I like the per-day pricing. Jakarta delivery was on the slower end of the estimate, about 10 days. Would still reorder.

- ★★★★★Finally, one thing per capsule
I've read too many labels that say 'proprietary blend 1,200mg'. Here it's one ingredient, one dose, printed. Bought two singles instead of my old multi.

- ★★★★★Paper trail is the point
I photograph the lot number of everything I take. This is the only store where that number leads to an actual document. Repeat customer now.

- ★★★★★Gift link surprised my mum
Sent the set to my mother through the gift link and she could see exactly what was in it before accepting. She's picky — she approved.

- ★★★★★Works out cheaper per day
The per-day price framing is honest — easier to compare than bottle prices. Delivery through the importer took 12 days to Bangalore, within what they quoted.

- ★★★★★Respects my requirements
As a Muslim buyer I usually have to email brands about capsule sources. Here the shell material is printed on the page and filtered automatically. Thank you.
