Source Naturals Ultra-Cal Night – Complejo de Calcio y Magnesio – 240 Comprimidos

What is a calcium and magnesium supplement?

Calcium and magnesium are two essential minerals that work synergistically for multiple bodily functions. Source Naturals Ultra-Cal Night combines both nutrients in a 1:1 ratio, using highly bioavailable forms derived from the Krebs cycle. This complex is designed to support bone and muscle health, as well as energy metabolism. Each tablet provides a balanced dose that facilitates absorption and utilization by the body.

Food supplements such as Ultra-Cal Night should not replace a varied and balanced diet, but they can be a useful tool to meet the daily nutritional needs of calcium and magnesium, especially in people with higher requirements or restrictive diets.

Benefits of taking a calcium and magnesium complex

According to the European Food Safety Authority (EFSA), calcium contributes to the maintenance of normal bones and teeth, normal muscle function, and the process of cell division. For its part, magnesium also contributes to the maintenance of bones and teeth, normal muscle function, and the reduction of tiredness and fatigue. In addition, magnesium is involved in normal energy metabolism and electrolyte balance.

The combination of both minerals in an adequate proportion is key, since magnesium helps regulate the absorption and distribution of calcium in the body. Ultra-Cal Night offers this optimal synergy, thus supporting the health of the skeletal and muscular system in an integral way.

Key ingredients: Krebs cycle calcium and magnesium

Ultra-Cal Night is distinguished by using Krebs cycle forms (also known as the citric acid cycle), which are natural metabolic intermediates. Calcium is presented as calcium citrate, calcium malate and other cycle compounds, which facilitates its absorption even in people with low stomach acidity. Magnesium is included as magnesium citrate and magnesium aspartate, highly bioavailable forms.

The 1:1 ratio of calcium and magnesium is supported by research suggesting an optimal balance for bone health. In addition, the product contains a cellulose and stearic acid base, and contains soy, so allergic people should take this into account.

How to choose the best calcium supplement?

When selecting a calcium and magnesium supplement, it is important to consider the form of the minerals, the ratio between them, and the presence of cofactors. Chelated or Krebs cycle forms often offer better absorption than calcium carbonate, especially if taken on an empty stomach. Ultra-Cal Night uses precisely these advanced forms.

We also recommend checking the dose per serving, the absence of unnecessary additives, and the manufacturer's reputation. Source Naturals, with more than 40 years of experience, manufactures its products in the USA under strict quality standards (GMP).

Dosage and recommendations for use

It is recommended to take 4 tablets daily, preferably at night, as magnesium can promote muscle relaxation and restful sleep. The tablets can be taken with or without food, although for optimal absorption it is suggested to take them with a glass of water. Do not exceed the recommended dose.

Store in a cool, dry place, out of reach of children. If you are pregnant, breastfeeding or taking medication, consult a health professional before using this product.
