Why has seaweed calcium become a new calcium source for children’s calcium supplementation?
In recent years, seaweed calcium extracted from marine algae has been widely praised by foreign nutritionists and environmental vegetarians. Researchers have found that seaweed, especially red algae, is an excellent source of calcium for the human body.
Red seaweed powder is rich in natural calcium carbonate. Since seaweed powder has a honeycomb porous structure (similar to the structure of human bones), it has a good buffering effect and is easily dissolved and ionized in the stomach and intestines and then absorbed. It is better absorbed than traditional calcium carbonate calcium supplements and is gentler on the stomach and intestines.
At present, many companies have begun to focus on developing a new generation of natural calcium supplement products – seaweed calcium. The Australian Fulvik R&D personnel have developed the Fulvik Seaweed Calcium series of calcium supplements for the delicate stomachs of infants and growing children. The proprietary molecular refinement process greatly improves the absorption of seaweed calcium. The dosage forms and flavors such as drops and gel candy-type fish gel have been loved by many families with children.
Childhood is the golden period for calcium supplementation
A person’s normal growth and development is generally divided into three stages: from birth to 2 years old is a rapid growth period, from 2 years old to adolescence is a stable growth period, and the third stage is adolescence. During the entire development period, bones grow every year, especially in childhood, and a large amount of calcium is needed to build strong teeth and bones.
Children’s calcium absorption rate may be as high as 60%, and the absorption rate slowly decreases to 15-20% in adulthood. With the increase of age, the absorption rate will even decrease. Therefore, targeted calcium supplementation in childhood lays a good foundation for adolescence and adulthood, and can also reduce the risk of fractures and osteoporosis.
Currently, there are three common types of calcium supplements for children on the market: inorganic calcium, organic calcium and natural calcium.
Inorganic calcium refers to calcium that is combined with calcium ions and inorganic substances, generally mineral calcium, such as calcium carbonate, calcium phosphate, calcium chloride, etc. The characteristics of inorganic calcium are high calcium content, especially calcium carbonate, which is easy to obtain and low in cost. Most calcium supplement products use calcium carbonate (mineral calcium), but the absorption of inorganic calcium requires the participation of gastric acid. Calcium must be freed in ionic form under the action of gastric acid before it can be absorbed by the body. Therefore, this type of calcium should be taken after or with meals.
Organic calcium refers to calcium that is combined with calcium ions and organic matter (synthetic calcium), such as calcium gluconate, calcium citrate, calcium lactate, etc. Some are combined with organic matter and inorganic calcium, such as organic calcium formed by the combination of amino acids and calcium acid. The calcium content of organic calcium is lower than that of inorganic calcium, and the cost is higher, but its absorption does not require gastric acid, and there is no limit on the time of taking it.
Another common form of calcium supplementation is natural calcium relative to synthetic calcium. Natural calcium is food or plants rich in calcium, which are directly used for calcium supplementation. For example, seaweed powder mainly contains calcium carbonate, and milk calcium extracted from dairy products mainly contains calcium phosphate. The characteristics of these natural calcium are that in addition to calcium, they also contain other nutrients. Although it also contains inorganic calcium, because these calcium itself exists in a biological state, compared with pure mineral calcium and synthetic calcium, it has advantages in absorption and utilization and gastrointestinal irritation.
Natural seaweed calcium will become the preferred choice for children’s calcium supplementation
In Australia, seaweed calcium is widely welcomed by professionals and families. Seaweed calcium comes from pollution-free seaweed and is rich in minerals. Therefore, seaweed calcium can enhance the biochemical activity of calcium and enable calcium to be fully absorbed and utilized, which is incomparable to traditional calcium preparations.
Seaweed calcium is algae calcium derived from plants. Unlike traditional mineral calcium, algae calcium is a body-friendly form of calcium that is naturally crammed with more than a dozen trace elements. Seaweed calcium is mostly taken from red seaweed. Generally, red seaweed is commonly found in tropical marine areas, and some even attach to other algae. Despite the red algae name, it can come in a variety of different colors.
Full Seiner Seaweed Calcium is extracted from a special species of red seaweed – Lithothamnion superpositum (lithothamnion sp.) – which is usually reddish-purple in color and found in waters outside of South America.

Red seaweed is more complex than most other algae, both at a cellular level and at a structural level. What makes seaweed calcium so unique is that it mimics the amount and variety of minerals found in human bones.
Seaweed powder has a honeycomb porous structure (similar to the structure of human bones), has a good buffering effect, is easily dissolved and ionized in the stomach and intestines, and then absorbed. It is much milder than pure calcium, has a higher absorption rate, and does not hurt the baby’s stomach. Because it is derived from plants, it also has incredible effects on the human body. Since the algae have pre-digested part of the calcium and minerals contained in the red seaweed, the human body will benefit and save a lot of effort in decomposing calcium.
Seaweed calcium is safer than mineral calcium
For decades, the mineral calcium has been the go-to choice for older adults looking to stave off the effects of bone loss. Most people who take calcium supplements don’t know that traditional calcium carbonate and calcium citrate supplements are extracted from rock. Specifically, limestone and marble.
An experiment in the United States showed that we consume a lot of non-food calcium (99% comes from mineral calcium), which will be deposited in the arteries to form plaques. This arterial calcification plaque blocks the arteries, leading to an increased risk of heart attack and stroke. Studies have shown that food and plant-based calcium do not cause arterial calcification and can provide other minerals. Calcium in marine algae is a safer choice than mineral calcium.
Algae calcium is naturally combined with magnesium and other trace minerals, so it is easily absorbed by the body. Therefore, seaweed calcium is a natural source of calcium nutrition that can fully meet the bone health needs of children.
Full Seiner is an innovative nutritional health brand rooted in Australian biotechnology. The children’s calcium supplement combination of seaweed calcium and mushroom vitamin D developed by its R&D personnel advocates the concept of natural and scientific calcium supplementation and has been highly recognized by professionals and children’s families.
Currently available in major maternal and child specialty stores across the country, such as Aiqin Maternal and Child, the FulviHealth natural calcium supplement combination of seaweed calcium and mushroom vitamin D is a natural plant-extracted nutritional supplement product imported from Australia . It is produced in accordance with cGMP/GMP and TGA (Australian Food and Drug Administration) standards to ensure high quality. At the same time, it is sourced from plants to ensure the purity of the ingredients. It is processed through molecular refinement technology, is green and natural, and is easier to absorb.
Scientifically formulated according to the baby’s developmental characteristics, it is non-irritating to the baby’s stomach and intestines, and can be taken by newborns as young as 0 years old; it has a high absorption rate and will not prevent the absorption of other nutrients in the baby’s body, so it can be taken safely at any time;
FulviHealth nutritionists recommend that babies in the rapid growth period should supplement calcium and vitamin D in a scientific and reasonable way in combination with their daily diet. The recommended daily intake of calcium is 250 mg per day from 5 months to 1 year old, and 600 mg per day for 1-3 years old, so 2-2.5 ml of seaweed calcium drops (1 ml contains 100 mg of calcium) or 1-3 seaweed calcium soft capsules (1 capsule contains 80 mg of calcium) are enough to meet the daily calcium needs of growth.
Fuweijian Mushroom Vitamin D helps the body absorb calcium from the diet. According to the national recommended dosage, infants and young children need to take 400IU of vitamin D per day. 1-2 capsules of Fuweijian Mushroom Vitamin D (about 200IU per capsule) per day can fully meet the baby’s vitamin D needs.
