Four nutrients in one tablet: calcium, magnesium, zinc and vitamin D3 - a combination often chosen for daily support of bones, muscles and the immune system. The format from 21st Century is convenient for a long course - 250 tablets are enough for more than two months at standard dosage.
Composition and dosage: what one serving contains
Serving size - 3 tablets per day. The manufacturer does not specify the exact milligrams in the text of the feed, but positions the product as a source of calcium, magnesium and zinc with the addition of vitamin D3 in the daily diet. Three tablets are taken during any meal.
- Calcium - the main mineral of bone tissue, present in each tablet
- Magnesium is a mineral often chosen to support muscle function and the nervous system.
- Zinc is a trace element that is part of the complex to support immunity
- Vitamin D3 (cholecalciferol) is a fat-soluble vitamin that helps absorb calcium from food.
Why is vitamin D3 needed in the complex?
Vitamin D3 - cholecalciferol - plays a key role in the absorption of calcium and phosphorus. This is why manufacturers of calcium complexes regularly combine these two nutrients in one formula: without sufficient levels of D3, calcium from food and supplements is absorbed much worse.
Cholecalciferol is synthesized in the skin under the influence of ultraviolet light, which is why it is also called the "sunshine vitamin." In regions with low insolation or with infrequent outdoor exposure, blood levels of D3 are often below optimal - and this is when supplements become appropriate as a dietary supplement. 21st Century Formula includes D3 along with calcium, magnesium and zinc to support this relationship in a convenient format.
How many tablets should I take per day and when?
The recommended dose is 3 tablets daily with any meal. Taking with food is advisable, as fat-soluble vitamin D3 is better absorbed in the presence of dietary fats. Do not exceed the recommended dose; consult a doctor if necessary.
How does this complex differ from individual D3, D3+K2 supplements or calcium monopreparations?
Separate vitamin D3 supplements - 2000 IU, 4000 IU or 5000 IU - are convenient when you only need to adjust the level of this vitamin. The D3+K2 complex is often chosen by those who want to additionally support the correct distribution of calcium in the body: menaquinone-7 (K2) acts as a cofactor in this process.
21st Century Calcium Magnesium Zinc +D3 formula takes a different approach: it focuses on three minerals at once, with D3 acting as a calcium absorption enhancer. This format is convenient when a person is looking for comprehensive daily support without having to buy several separate supplements.
Composition of excipients and features of the formula
The tablets contain cellulose, croscarmellose sodium and gum arabic as the main excipients. Also included are less than 2% of magnesium silicate, magnesium stearate, polyethylene glycol, polyvinyl alcohol, silicon dioxide, stearic acid and titanium dioxide.
The product is certified gluten-free and non-GMO . 21st Century states that each batch undergoes laboratory testing, a standard the company has maintained for over 30 years.
Who is this format suitable for?
The complex is designed for adults. Convenient for those who want to get calcium, magnesium, zinc and D3 in one package and do not want to count several different capsules every day. 250 tablets - a large bottle, aimed at long-term use.
This is a dietary supplement, not a medicine. It does not replace a balanced diet and is not a substitute for medical advice.
