Ingredient Story

Lithothamnion Calcareum 400mg

Caliron has extracted calcium from natural calcified red seaweed (Lithothamnium sp.) that contains a wide variety of essential nutrients, including calcium, magnesium, boron and zinc.

Vitamin D3 1000IU

Vitamin D3 is the body’s preferred form of this essential fat-soluble micronutrient, and with 1000 IU in each capsule, is effective at raising and maintaining vitamin D levels in the body daily to optimize calcium absorption.

Vitamin K2 4mcg

Augmented with Vitamin K2. It plays an essential role in bone metabolism by activating osteocalcin, which binds calcium from blood circulation to the bone matrix.


Recommended Dose
Adult: Take 1 – 2 capsules once daily or as recommended by the pharmacist or doctor.  

Store your health supplements in a cool, dry place and keep them out of reach of children. Do not use if the seal is broken, follow the expiration date, and consult with a healthcare professional if needed. 

Frequently Asked Questions

What is the difference between natural calcium extracted from Algae and calcium carbonate?

Natural algae calcium is better absorbed as compared to synthetic calcium carbonate. The unique honeycomb structure of red alage increases surface area and creates more points for absorption along your digestive tract.  

What makes Caliron different from other calcium supplements?

First of all, Caliron comes in easy-to-swallow capsule form. We have listened to all customers’ concerns about swallowing large calcium tablets and formulated Caliron in smaller and easier-to-swallow capsule form, making sure a better experience so that you can get the possible results.  

It also comes with Vitamin D3 and K2 which optimizes the calcium absorption and retention to the bone.   

Best part of it is that it is vegetarian-friendly!
