Calcium and its multiple functions
Calcium is the most abundant mineral element in our body, which is why we cannot be without a nutrient of these characteristics in our lives.
It’s vital for the normal growth and development of bones in children, and calcium and vitamin D also contribute to reducing bone demineralisation in postmenopausal women. Low bone mineral density is a risk factor for osteoporotic bone fractures.*
* The statement is specifically aimed at women aged 50 years and older. The beneficial effect is obtained with a daily intake of at least 1200 mg of calcium and 20 µg of vitamin D from all sources.
It has many functions:
- It contributes to normal blood clotting.
- It contributes to normal energy metabolism.
- It supports normal muscle function.
- It contributes to normal neurotransmission function.
- It contributes to normal digestive enzyme function.
- It contributes to the process of cell division and differentiation.
- It's necessary for the maintenance of healthy bones.
- It's necessary for the maintenance of healthy teeth.
With all these qualities, you can see why it's important to ensure optimal levels of calcium in your body – and one fail-safe way to do so is to take a calcium-rich supplement.




What foods contain calcium?
Food is the main nutrient source of calcium. Below there are some of the most calcium-rich food you can find:
- Dairy products: milk, yoghurt and cheese.
- Vegetables: broccoli, kale, leek and spinach.
- Fruits: kiwi, strawberries, raspberries, figs, plums and papaya.
- Nuts: pistachios, almonds, nuts and peanuts.
- Fish and seafood: prawns, langoustines, clams, salmon and tinned sardines.
If our diet doesn't cover our calcium needs, we can take a dietary supplement to cover the deficit.
At HSN, we have a wide and select range of products from the EssentialSeries and RawSeries brands that contain both calcium and other fortifying supplements that strengthen its properties.
Where to buy calcium
You can buy this mineral in our online shop, in the sports nutrition section, in the ingredients category. We offer both calcium and calcium citrate available in various forms that will make your life easier:
- If you want to enjoy the purity of the compound, go for the powder version so that you can mix it with water or natural citrus juice.
- The capsules are easy to swallow thanks to their reduced size. They're also entirely plant-based.
- Our capsules are always coated with plant polymer (cellulose).
EssentialSeries and RawSeries provide you with the best products to help optimise your metabolism*:
* Calcium contributes to normal energy metabolism.
If you're looking for a 100% natural product, you've found it with this raw powder.
This compound is better-absorbed than other forms, such as calcium carbonate, in its purest form with no excipients or chemical additives and no flavour surprises, no taste at all. Neutral has never been so incredible. As it's free of animal ingredients, it's also suitable for vegetarians and vegans. We are also concerned about your allergies so this allergen-free product can be taken with complete peace of mind for your allergic reactions.


Calcium citrate also has a soul mate: vitamin D. Together, these two indispensable elements are essential for the proper functioning of the body. They're needed in conjunction to:
- aid growth and development in childhood.*
- help reduce bone mineral loss (low bone mineral density is a risk factor for bone fractures due to osteoporosis in osteoporotic women).*
* Calcium and vitamin D are needed for the normal growth and development of bone in children.
* In addition to the aforementioned mention, it also has the compulsory declaration of use.
The body reabsorbs calcium and phosphorus from the bones, rather than preserving the mineral, which causes them to weaken. As the body only absorbs 20-40% of the total amount itself, vitamin D can aid its absorption.*
* Vitamin D contributes to the normal absorption and use of calcium and phosphorus.
We have therefore made a product to improve bone health based on:
- Calcium Citrate + Vitamin D3 (cholecalciferol), by EssentialSeries.
The formula combines a mineral and a vitamin to form the perfect complex for your bones, presented in small, easy-to-swallow vegetable capsules, with 120 servings.
They are 100% suitable for vegan and vegetarian diets thanks to their plant-based and coeliac-friendly raw materials, free from artificial colours preservatives.
The supplement based on:
- Calcium + Magnesium + Vitamin D3 by EssentialSeries in a pack of 120 easy-to-swallow tablets. Free of additives and animal derivatives, suitable for vegans.
It has a high concentration of calcium, mineral salts and vitamin D. Nutritional reference values aren’t just a number for us; we care about providing quality ingredients.
