Why Calcium Citrate Over Other Forms?
Unlike Calcium Carbonate, which requires a heavy amount of stomach acid to break down, Calcium Citrate is an acidic form of calcium that is absorbed effortlessly—with or without food.
- Gentle on the Gut: Significantly lower risk of gas and constipation.
- Flexible Timing: Take it anytime, anywhere—no need to plan around heavy meals.
- Ideal for Seniors: As stomach acid naturally decreases with age, Citrate ensures you’re actually getting the minerals you pay for.
Calcium Citrate vs. Calcium Carbonate:
The most common question from both retail customers and B2B formulation buyers is: “Which form of calcium is best?”
While calcium carbonate is cheaper and contains a higher percentage of elemental calcium by weight, it has a major drawback: it requires stomach acid to dissolve and absorb. This means it must be taken with a heavy meal, making it highly inconvenient.
In contrast, Calcium Citrate is highly soluble and easily absorbed by the body, regardless of stomach acid levels.
| Feature | Calcium Citrate Capsules (Reson / Ausreson) | Typical Calcium Carbonate Tablets |
| Absorption Efficiency | Outstanding; does not require stomach acid | Moderate; strictly requires stomach acid |
| Digestive Comfort | Highly gentle; low risk of gas or bloating | High risk of constipation, gas, and bloating |
| Timing Flexibility | Can be taken on an empty stomach or with food | Must be taken immediately after a meal |
| Ideal For | Seniors, post-surgery patients, those on antacids | Adults with strong digestive systems |
The Power of the Capsule Formulation
Choosing the capsule format over traditional compressed tablets provides a massive competitive advantage for modern brands.
Compressed tablets often contain binders, glidants, and heavy coatings that can delay dissolution in the gut. Ausreson's calcium citrate capsules utilize premium, fast-dissolving vegan/gelatin shells that release the active micro-powder quickly upon reaching the stomach.
A common complaint among aging demographics—the primary consumer base for bone support supplements—is that large calcium tablets are difficult to swallow. Two-piece capsules feature a sleek, natural glide that makes daily compliance effortless.
Capsules allow for synergistic ingredient blending without the risk of physical degradation during pressing. To maximize calcium efficacy, we can easily co-formulate your capsules with:
-
Vitamin D3: Enhances intestinal calcium absorption.
-
Vitamin K2 (as MK-7): Directs calcium straight to the bones rather than depositing it in the arteries.
-
Magnesium: Balances bone mineral density ratios.

Frequently Asked Questions
Q: Why is the capsule size larger than others?
- A: Calcium Citrate is a more voluminous molecule than Calcium Carbonate. To provide a therapeutic dose of elemental calcium without using compressed tablets (which can be hard to swallow and digest), we use clear, easy-to-swallow vegetable capsules.
- A: Yes, but be mindful that high doses of calcium can interfere with the absorption of iron and zinc. If your multivitamin contains these minerals, try to space your Calcium Citrate dose at least 2 hours apart.
- A: Yes. Our Calcium Citrate is 100% mineral-derived and encapsulated in non-GMO vegetable cellulose.
