Why Choose Plant-Based Calcium?
Algae Calcium is sourced from marine algae and provides calcium in a food-based mineral matrix similar to human bone. Unlike conventional calcium derived from limestone, algae calcium is naturally bioavailable and well tolerated, making it suitable for daily use.
This natural structure allows the body to absorb and utilize calcium more efficiently, without placing unnecessary stress on digestion.

Benefits of Algae Calcium vs Other Calcium Types
What is Elemental calcium ?
So as to understand elemental calcium take example of calcium carbonate - Calcium ion is having Valency of Ca** where 1 single ion is unstable to make it stable two ions 1 of elemental carbon & 1 of elemental oxygen is added to make it stable, when you consume they break from each other & you get pure calcium known as Elemental calcium refer. EC
Calcium Carbonate-( EC 40 % ) [1] Derived from Limestone, chalk powder, Results low absorption / Renal calculi* / GI disturbance / Constipation
Calcium Citrate-( EC 21 % ) Derived from reacting calcium compound with citric acid Results low absorption & rock derived
Calcium Ascorbate-( EC 10 % ) Derived from reacting calcium compound with ascorbic acid. Results very low elemental calcium, low absorption as rock derived calcium compound.
Plant Based Calcium-( EC 30 % ) Derived from plants. Like Red marine algae ( Lithothamion Superpositium ) Results better absorbed calcium, Very less chances of GI disturbance, Renal calculi or constipation.

Frequently asked Question about Algae Calcium?
Q-What is Algae calcium & How it is different from other calcium?
Algae calcium is a plant-based calcium sourced from red marine algae. Unlike traditional calcium carbonate or citrate, algae calcium contains naturally occurring 72 trace minerals that support better absorption and bone utilization, making it a more complete and gentle option for daily bone health with very fever side effects
Algae calcium is derived from kiwi sized South American marine algae. This Algae is Farmed, Dried & Powdered without any Heating or additive usages.
-
Algae Calcium is world’s only USDA certified raw calcium powder having certified Purity ,Stability and Sustainability
-
Algae Calcium is having Non-GMO, Gluten-free, Soy-Free, Dairy-Free and Kosher Certification
-
Zyrocal and Periosteum K2 contains algae calcium which is in “PRE-DIGESTED” form ensuring to absorbe it more readily if compared with rock or chemical calcium that offers lots of side effects
Making Zyrocal & Periosteum K2 best Calcium supplement & Osteoporosis Treatment
The Red Algae (Lithothamnion - Superpositium) present in Zyrocal tablets and Periosteum K2 also contains all 12 essential bone health supporting minerals like Zinc, Vanadium, Potassium, Silicon, Selenium, Nickel, Boron, Copper, Magnesium, Manganese,
Strontium, Phosphorus along with our added fortification of Vitamin D3,Vitamin k2-7 and Cissus Quadrangularis in Periosteum K2 and +Magnesium & Zinc in Zyrocal Tablets so as to ensure Zyrocal & Periosteum K2 as best Calcium Supplement for healthy bones and Osteoporosis Treatment.
Q-Is algae calcium better absorbed by body?
Yes. Algae calcium is considered highly bioavailable, especially when combined with Vitamin D3 Vitamin K2, and Magnesium which help direct calcium to the bones instead of soft tissues or joints improving overall absorption and effectiveness.
Q-Is algae calcium supplement getle on stomach?
Yes. Being plant-based and naturally derived, algae calcium is easier on the stomach and less likely to cause bloating, constipation & Renal calculi compared to conventional calcium supplements.
Q- Who should take this supplement?
This supplement is ideal for:
-
Adults concerned about bone density
-
Women and men above 30 years
-
People with low dietary calcium intake
-
Individuals looking for a plant-based calcium alternative
-
Those sensitive to traditional calcium supplements
Q- How Magnesium D3 K2 & Zn helps with calcium utilisation?
-
Vitamin D3 helps the body absorb calcium from the gut to circulation
-
Vitamin K2 ensures calcium is deposited into bones and teeth rather than arteries and transport absorbed calcium towards bone.
-
Now the role of Magnesium citrate comes where Magnesium ensures calcium will go to outer lining of bones instead of joints.
Together, D3 K2 & Magnesium maximize the benefits of algae calcium for long-term bone health.
Q-Why Magnesium is Important in Calcium Metabolism?
A Study "Published in- Nutrients" 2013, 5, 3022-3033
Magnesium Deficiency leads to Osteoporosis directly by acting on Crystal formation & on bone cells and indirectly by impacting on the secretion & activity of PTH ( Parathyroid hormones )
A Study “Published in-European Journal of Rheumatol"-Mar 2018
“Magnesium Disorder Can cause calcium Pyrophosphate Deposition disease also known as Calcification of joints, Pseudo-gout ,CPDD or inflammatory arthritis”
This Study shows that Hypomagnesemia is a cause of CPPD disease. Magnesium levels should be measured as part of diagnostic work-up of CPPD disease, especially in younger patients, Also if Calcium alone Is taken without Magnesium it can cause deposition of calcium in Joints leading to Stiffness, Pain and reduce joint's flexibility.
A Study Published in “British Medical Journal” –July 2017
States that “Decreased Magnesium status may mediate increased Cardiovascular Risk associated with Calcium Supplementation”
This study shows that Calcium supplement without highly bio-sorbed magnesium can cause Cardiovascular Disease. Peoples who wish to supplement with calcium were well advised to take Calcium supplementation that also include highly bioavailable magnesium in a calcium to Magnesium ratio of 1:1
Q-What is Dosage of Algae calcium & How to take it?
It depends upon your bone density or as suggested by your healthcare professional However for better results it can be taken as 1 or 2 tablets in a day with meal along with 100ml water
Q-Is Algae calcium safe for long-term use?
When taken within recommended dosages, algae calcium with D3, K2, magnesium, and zinc is considered safe for long-term daily use as it is not rock or chemical its plant based calcium. Always consult a healthcare provider if you have medical conditions or are taking other medications.
Unlike traditional, rock-derived or chemical sourced calcium supplements, Zyrocal has no adverse side effects such as kidney stones or arterial calcification. Zyrocal is a natural, plant-sourced calcium that is easy for your body to absorb. It’s similar to calcium you get from eating vegetables such as broccoli, kale and peas. Some studies have shown that calcium from food sources does not increase soft tissue calcification because foods that naturally contain calcium also supply other minerals, which helps transfer the calcium directly into your bones rather than soft tissues like arteries, kidneys and eyes. Additional magnesium, vitamin K2 Vitamin D3 and Zinc are added into Zyrocal to optimize absorption and transport to the bone rather than soft tissues. All these factors translate to efficient absorption and placement into bone tissue. Zyrocal is also much safer for you because it is more effective at a lower dose. At 500 mg per day of calcium, Zyrocal is increasing bone density in adults. Compare that to regular calcium supplements that have been studied at 1200 mg per day – and only slow bone loss.
Q-Is Zyrocal Known to Doctors?
Absolutely! “Zyrocal is a unique bone health supplement,” Says medical expert. Its ability to increase bone density was confirmed by 3 clinical studies. And that’s why Zyrocal is supported by thousands of medical professionals.
