Inside this capsule
This capsule
Calcium
From marine algae (Aquamin) · 500 mg
One ingredient. The dose on the label is the dose in your hand, and the lot number traces it back to one supplier: Marigot (Aquamin).
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
Calcium's role in maintaining normal bones is an authorised nutrient function.
Where it sits on our scale
Traditional use
Long use, thin trials — we say so
Moderate evidence
Human trials, small or mixed
● Strong evidence
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
We don’t publish a window for Calcium. The trial record doesn’t support one, and a number we can’t defend is worth less than none.
Take it with / keep it apart
Single ingredients let timing work for you — blends lock everything into one swallow.
◐ Keep apart from Iron
Calcium and iron compete for shared uptake pathways in the small intestine; calcium taken together measurably lowers iron absorption. → Take them at meals at least 2 hours apart. (NIH ODS Iron Fact Sheet)
◐ Keep apart from Zinc
Calcium interferes with zinc absorption when taken in the same sitting at supplemental doses. → Different meals — 2 hours apart is enough. (NIH ODS Zinc Fact Sheet)
◐ Keep apart from Psyllium Husk
Soluble fibre gels in the gut and can carry minerals through before they absorb. → Psyllium gets its own slot, 2 hours clear of minerals. (Product labelling standard for bulk fibre; NIH ODS Calcium Fact Sheet)
◎ Pairs well with Vitamin D3
Vitamin D drives active calcium absorption in the gut. → Same meal works in your favour. (NIH ODS Calcium Fact Sheet)

- ★★★★★The schedule advice is underrated
The bot told me to keep this away from my iron at a different meal. My pharmacist said the same thing when I asked. Nice to see a shop that knows timing matters.

- ★★★★★Subscribed after one month
Tried one-time first, then switched to subscribe. The cancel-anytime wording was what convinced me to commit — and it really is one click, I tested it.
Marcus L. · SG · 2026-08-24
- ★★★★★Better than my old brand
Switched from a supermarket brand. The form here absorbs better according to what I've read, and at least the dose isn't hidden in a blend total.

- ★★★★★Third order
First order was a test, second was for my husband, third is the subscription. The consistency between lots is what keeps me — same look, same certificate format, no surprises.

- ★★★★★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.
