Elastin and collagen for the joints

I wanted to know if you have a product that provides elastin and collagen for the joints.

A/ We do not have any product that provides collagen directly, instead we have products with nutrients that help increase the natural production of collagen in the body. Below we summarize the nutrients that could be useful for that purpose.

It is believed that the substances called anthocyanidins (powerful antioxidants belonging to the family of flavonoids, vegetable chemicals) help to increase the amount of vitamin C in your body, as well as to strengthen collagen. They can also increase the production of elastin, a substance that gives the skin its elasticity. The anthocyanidins are found in the skin of dark fruits and with varied colors such as: blueberries, blackberries, raspberries and red grapes. Flavonoids are the pigments that give these fruits their distinctive color. Another way to consume them is in the form of a nutritional supplement.

Silicon, although found only in minute quantities in the body, is necessary for cell growth and is present in almost all structurally strong tissues such as arteries, tendons, trachea, connective tissue, hair, cornea and nails. Good dietary sources of silicon are cereals such as oats, barley and rice, but refining processes can eliminate much of this mineral away. Silicon contributes to the structure and elasticity of the connective tissue and seems to play an important role in bone synthesis and cartilage collagen.

(Español) Ácido Ascórbico o Vitamina C pura

I would like to buy vitamin C from LAMBERTS®, but I do not see clear whether it is ascorbic acid or pure vitamin C, because I have been advised not to buy ascorbic acid because it is not exactly vitamin C.

R/ Ascorbic acid is the most common form of vitamin C found in nutritional supplements and is also the form found in foods. Therefore, it is not true that ascorbic acid is not pure vitamin C as you have been informed.

On the other hand, vitamin C can be obtained naturally and synthetically. The natural sources are levorotatory ascorbic acid (L-isomer) and levorotatory sodium ascorbate, present in different foods. Most of the production of vitamin C used to be synthetic; however, today most of the world production is obtained via fermentation with microorganisms that constitutes a natural form of production.

Synthetic ascorbic acid produced from corn is increasingly disused, however, even though Lamberts obtains its vitamin C from natural sources, the affirmation maintained in certain media, that synthetic vitamin C has less bioavailability and activates than a natural vitamin C, totally and absolutely lacking clinical evidence that can sustain it.

There are other chemical forms of vitamin C that are called mineral ascorbates. In this type of vitamin C, minerals are combined with ascorbic acid, resulting in less acidic mineral salts of ascorbic acid. Their pH is 5 to 7. Therefore, in theory they are less irritating to the gastric mucosa than ascorbic acid, however, there does not appear to be conclusive clinical evidence that this is so. Calcium ascorbate, sodium ascorbate, potassium ascorbate and magnesium are the most common forms.

What some studies have shown is that ascorbic acid combined with citrus bioflavonoids is more bioavailable than the synthetic form of ascorbic acid alone (Marti, Mena et al., 2009). Indeed, in nature, vitamin C is present together with other substances, which help increase its absorption and bioavailability.

On the other hand, the rose hip is one of the plant sources richest in vitamin C, since approximately 7% of its weight corresponds to the vitamin.

The most popular formulations of Lamberts, following these strict clinical parameters, are those that combine ascorbic acid of vegetable origin with citrus bioflavonoids and rosehips. These formulations are usually of time release to avoid any possibility of acidification in the organism.

However, we also have vitamin C in the form of calcium ascorbate in other formulations, to satisfy users who prefer the administration of this form of vitamin C or require ingesting large doses of it by indication of a health professional.

Non-acidic vitamin C for infections

What option of non-acidic vitamin C, would be better for infections?: Gentle C, Ester C or Ascorbic Acid?

R/ With the exception of the original form of vitamin C (ascorbic acid), all other options are valid. Gentle C provides calcium, so the choice depends on other needs. If calcium intake is preferred then the Gentle C is the best option. Any of the other two are useful and you may adjust the dose.

What excipients your vitamin C has in the Ascorbic acid form?

I wonder what excipients carries your vitamin C in the form of Ascorbic acid, or if it is completely pure.

R/ vitamin C powder of LAMBERTS® does not produce problems for celiac disease. However, if you allow me the recommendation, given that your gut is certainly very sensitive, possibly within the forms of vitamin C powder (which has no excipients that are used to compress or tableting), Ascorbate of calcium instead of Ascorbic acid (vitamin C pure), it would be better. The calcium Ascorbate is a presentation of Ascorbic acid with a small amount of calcium which prevents the acidity of Ascorbic acid and is more suitable for sensitive digestive systems. Each ¼ teaspoon dose contains: 897 mg of Ascorbic acid and 103 mg calcium. The form of Ascorbic acid contains only Ascorbic acid, i.e. by the same amount-dosage contains 1000 mg of Ascorbic acid.
