A Comprehensive Guide to Vitamin C Supplements

Vitamin C is a properly-regarded antioxidant nutrient with a wide range of functions in the human system, such as collagen synthesis, wound healing, protein rate of metabolism, synthesis of neurotransmitters and L-carnitine, and immune process support.

Though it is not terribly tricky to get hold of ample quantities of this nutrient from a whole food, nutrient-dense diet regime, in some cases a very little extra could possibly be warranted.

So, you choose to look for out a excellent vitamin C health supplement, only to uncover that there are about a gazillion alternatives to decide on from at your local grocery or overall health foodstuff retail outlet.

The pursuing post seeks to make clear a minor little bit about the sorts, resources, delivery procedures, and dosages of vitamin C health supplements on the current market in get to make informed selections for oneself or your clients.

First, let’s glance at the most frequent types and resources of vitamin C nutritional supplements you may well face.

Ascorbic Acid

Vitamin C and L-ascorbic acid are deemed to be synonymous. Most nutritional supplements you will experience incorporate ascorbic acid from artificial or normal sources, which are typically identical in the molecule’s condition and biological activity.

The molecule ascorbic acid can be oriented in two strategies: with the atoms rotating to the left (L-ascorbic acid) or rotating to the correct (D-ascorbic acid). What is crucial to know is that in character, plants, microbes, and animals with the potential to produce ascorbic acid that rotates to the still left. Individuals, who can’t produce ascorbic acid, also use the L kind.

Pure ascorbic acid takes place in foods, notably fruits and vegetables like strawberries, kiwi, papaya, citrus fruits, and all sorts of peppers. For “natural” vitamin C nutritional supplements, ascorbic acid is manufactured by allowing particular germs, like Saccharomyces cerevisiae, to ferment a sugar substrate, like glucose or sorbitol.

Artificial ascorbic acid is generally created industrially by a system referred to as the Reichstein approach, which utilizes chemical and microbial ways to convert D-glucose to L-ascorbic acid. Glucose for synthetic ascorbic acid ordinarily arrives from corn, which can be seriously processed and is often genetically modified, so take into account the excellent and source of the substances when deciding upon this sort of supplementation.

As the identify suggests, ascorbic acid is acidic. For that reason, some men and women may possibly be delicate to huge doses, probably enduring gastrointestinal irritation or diarrhea. If this is a worry, the upcoming sort may be gentler on the gut.

Mineral Ascorbates

Mineral ascorbates are a salt consisting of an ascorbate ion (negative cost) certain to a mineral ion (constructive cost). Most generally, the mineral employed in ascorbates is sodium or calcium. Other ascorbates may have potassium, magnesium, zinc, molybdenum, chromium, manganese, or a mixture of these.

Ascorbates are ascorbic acid minus an acidic hydrogen atom. Dropping the hydrogen will make this variety of vitamin C neutral in pH, as a result mineral ascorbates are also regarded as buffered vitamin C. They are formed by reacting ascorbic acid with mineral carbonates, like calcium carbonate or sodium bicarbonate.

An significant factor to keep in mind when choosing a vitamin C nutritional supplement in this type is that the mineral is also absorbed, and contributes to your day by day calcium, or other mineral, consumption.

Vitamin C with Bioflavonoids

In mother nature, vitamin C will come packaged in with a whole large amount of other nutrition, which include fiber, phytonutrients, and other vitamins and minerals. Some vitamin C nutritional supplements request to mimic nature’s packaging by like polyphenolic compounds identified in crops, known as bioflavonoids.

Even with significant investigate, it is even now unclear whether or not the addition of bioflavonoids boosts the bioavailability of vitamin C, even though phytonutrients undoubtedly have their personal rewards, which includes currently being anti-oxidants. The theory is that when bioflavonoids are taken with vitamin C, bioflavonoids can neutralize absolutely free radicals encountered in the digestive tract, as a result sparing vitamin C to be much more accessible for absorption and use somewhere else in the system. Bioflavonoids on their own do not take up into the bloodstream incredibly perfectly, so it is tricky to measure their availability in the physique, let on your own their outcomes on vitamin C absorption.

Nutritional supplements made up of bioflavonoids are frequently sourced from entire meals prosperous in vitamin C and bioflavonoids, this sort of as citrus fruits, acerola cherry, rose hips, and other fruits and veggies. Some health supplements are promoted as “raw”, indicating they are only sourced from organic components (together with ascorbic acid derived from bacterial fermentation) and usually incorporate enzymes and probiotics.

Mineral Ascorbates + Metabolites

However a further type of vitamin C health supplement is patented beneath the identify Ester-C^Ⓡ. In addition to mineral ascorbates, Ester-C^Ⓡ also includes vitamin C metabolites, which include dehydroascorbic acid, which is oxidized vitamin C, and other compounds this sort of as calcium threonate, xylonate, and lyxonate.

You may possibly be questioning why oxidized vitamin C is a fantastic plan to consider as a complement. Why is it valuable to get an antioxidant that is presently oxidized?

The solution is in the absorption. Oxidized ascorbic acid enters cells utilizing a distinct form of protein transporter in the intestines, giving this molecule an alternate entry stage into cells than ascorbic acid. At the time inside the cells, the entire body reduces dehydroascorbic acid to its handy form, and voilà, the antioxidant life on to neutralize a further cost-free radical.

Liposomal Vitamin C

Vitamin C is a drinking water-soluble vitamin. As these, it is not saved in cells and tissues in any appreciable quantity, so steady everyday ingestion is crucial. In addition, it demands a small little bit of aid from protein transporters to cross the lipid barrier of mobile membranes (additional on these protein transporters afterwards).

To circumvent these solubility difficulties, some vitamin C nutritional supplements are built to encompass h2o-soluble ascorbic acid in very small fats-soluble offers, termed liposomes. Liposomal vitamin C is intended to incorporate body fat-soluble particles and drinking water-soluble vitamin C with each other in get to increase security and facilitate access into the cells.

Supplemental Vitamin C Delivery, Dosage, and Absorption

All over these descriptions of the numerous forms of vitamin C health supplements, I’ve outlined the use of protein transporters a handful of moments in reference to how this vitamin receives inside of cells.

Regardless of whether from meals or nutritional supplements, the the vast majority of vitamin C is absorbed with the enable of sodium-dependent active transporters, which are proteins that aid the drinking water-soluble molecule cross the lipid-primarily based membrane bordering cells. Most vitamin C nutritional supplements – liquids, powders, pills, and capsules – are ingested orally and absorbed in this way.

Decades of study ensure that these proteins come to be saturated at superior concentrations of vitamin C, with absorption decreasing at and over 200 mg. Looking at this proof, several tiny doses of supplemental vitamin C may be extra powerful than a solitary massive dose for absorption and assimilation.

As now mentioned, oxidized vitamin C, dehydroascorbic acid, has an additional entry position. It enters cells with the assist of facilitated glucose transporters, one more sort of protein. Vitamin C competes with glucose for entry to these proteins, so higher concentrations of sugar block dehydroascorbic acid from getting into cells in this way.

Liposomal vitamin C supplements bypass the will need for these transporters, as the vitamin is encased in lipid compartments that can passively diffuse across mobile membranes. This style of supplement is promising in that it may attain bigger circulating concentrations of vitamin C than usual oral formulations.

Encouraged Vitamin C Intakes and Other Criteria

The recommended dietary allowance (RDA) for vitamin C is as follows:

• 90 mg/working day for males
• 75 mg/day for gals
• Smokers might need an more 35 mg/day

Other aspects that may well boost the have to have for more vitamin C involve being pregnant, lactation, selected medicines, wound therapeutic, diet programs of weak dietary excellent, and stress.

The tolerable higher restrict (UL) is 2000 mg/working day, which is the best intake that is probable to make no adverse wellness consequences in the typical populace.

Individuals with higher iron degrees should really be cautious about vitamin C supplementation, as vitamin C improves the absorption of iron.

A Holistic Approach to Vitamin C Adequacy

As nutrition remedy practitioners, we identify that dietary supplements are merely a software to augment nutrient ranges on top rated of a potent foundational food plan based on whole foods. Vitamin C-rich foods convey more rewards through the synergistic results of an abundance of vitamins and minerals, these kinds of as macronutrients and micronutrients together with nutritional vitamins, minerals, and bioflavonoids.

To close, I’ll share a uncomplicated infusion I acquired from the director of the Nutrition Therapy Institute, Dianne Koehler, in a person of the classes supplied as aspect of the Nourishment Therapist Master Certification Method.

To make the infusion you will need to have:

• Dried, coarsely floor rose hips
• A little bit beneath boiling temperature h2o

Pour 8-12 ounces of scorching drinking water around about a teaspoon of coarsely ground rose hips. Allow for it to infuse for 5-10 minutes. Pressure and love.

In addition, you can grind rose hips to use as an different to vitamin C powder. Rose hips are a wonderful source of vitamin C, vitamin E, necessary fatty acids, and bioflavonoids.

I hope this posting get rid of some light on the intricate globe of nourishment nutritional supplements. If you’d like to study extra, contemplate enrolling at the Diet Treatment Institute to develop into a Nourishment Therapist Learn!
