Trinny & Shabir on Immunity

Currently there is a lot of confusion as to how we can all keep our immune system healthy and primed.  But what exactly is our immune system?

The immune system, unlike any other bodily system, comprises of a complex series of interactions between various glands, such as the thymus gland and tonsils, proteins, chemical compounds, hormones, white blood cells and probiotics that all work in synergy to try and make our bodies less susceptible to infections. Many of these chemical compounds require nutrients in order to work effectively, for example a deficiency in vitamin D3 may result in dormancy of white blood cells which are normally required to engulf and eradicate bacteria and viruses that enter the bloodstream.

Is Tetrahexyldecyl Ascorbate The Best Vitamin C Serum?

Pure Vitamin C serums for the face containing L-Ascorbic Acid are beneficial for the skin helping to protect against damaging free radicals that encourage wrinkles by destroying the collagen matrix. They also help to brighten and freshen the appearance of dull looking skin, together with inhibiting the formation of pigment in skin prone to hyperpigmentation. However, Vitamin C serums containing pure L-ascorbic acid do have some limiting factors which can influence their effectiveness.  We explore:

Limiting Factors of Vitamin C Serums

Most vitamin C serums are water-soluble because L-Ascorbic Acid, known as vitamin C or L-AA for short, disperses evenly in a water-based serum, but therein lies a problem. The dermis of the skin has a rich lipid (oil) barrier and it is here that many of the nutrients, including vitamin C, are required to manufacture collagen, a protein that gives skin its youthful firmness and the ability to resist wrinkles. Using water soluble vitamin C serums containing L-AA can be an issue since this nutrient cannot make it through the oil barrier and therefore cannot provide maximum benefits as far as collagen manufacture is concerned.

To overcome this, some formulators use very high strengths of L-ascorbic acid (including us) so that at least some of this vitamin will be delivered to the dermis, however this can still be a problem and we are aware of this. If you have sensitive or reactive skin, such high strength vitamin C serums can cause tingling, irritation, redness and may be uncomfortable to use.

Vitamin C is highly pH dependant. It only works at a low pH since it is an acid and anything added in the serum that is alkaline will neutralise it, rendering it ineffective. Formulating this form of vitamin C into a serum is not easy because you have to use preservatives and other ingredients that have a low pH and this can be problematic especially to those with sensitive skin.

Another problem can arise using high strength vitamin C serums containing L-ascorbic acid. L-Ascorbic Acid is highly unstable when exposed to light and/or air. It oxidises to Dehydro Ascorbic Acid (DHAA)which then further degrades to different irritating acids. In effect, the best case is that you may have a product that is not so effective and the worse case is that the oxidation creates free radicals that are actually damaging to the skin. To mitigate this during the day, a sunscreen is absolutely imperative, but it is unlikely that this will provide protection all day unless applied reasonably frequently.

These are just some of the limiting factors of using the pure acidic form of vitamin C, L-Ascorbic Acid. This has led to a host of synthetic vitamin C derivatives such as magnesium ascorbyl phosphate, ascorbyl palmitate and numerous other vitamin C esters.

Vitamin C derivatives

When a compound is added to vitamin C, such as a palmitate or phosphate, this then changes the compound making vitamin C less likely to degrade. So aside from being less likely to degrade, the other advantages of vitamin C derivatives is that they are less irritating and to a large extent not dependant upon pH.

The disadvantage of these derivatives is that they tend to be less effective than L-ascorbic acid. Many of these derivatives tend to be water soluble meaning that tend to work only on the surface layers and some of the oil soluble derivatives such as ascorbyl palmitate tend not to be converted into ascorbic acid when they reach the dermis meaning they are not that beneficial.  Knowing these limitations, we have been in research and development and the result is C-Deep Vitamin C Serum.

Tetrahexyldecyl Ascorbate

Tetrahexyldecyl Ascorbate is a form of vitamin C which has been modified to be soluble in oil or lipids. Studies indicate that it not only penetrates the epidermis, the uppermost layer of skin, but also the dermis, which is the deepest layer of skin. In fact, it penetrates the skin faster and deeper than any other form of vitamin C.

So if it penetrates both layers of the skin, does this make it more effective? Vitamin C derivatives need to be converted into L-ascorbic acid; it is the L-ascorbic acid element that fades away your age spots, enhances collagen production and fights free radicals. Studies indicate that Tetrahexyldecyl Ascorbate does convert into L-ascorbic acid and behaves in exactly the same way as L-ascorbic acid, but without the limitations.  This is important.

Its benefits are:

Provides potent antioxidant protection by destroying free radicals that cause premature ageing of skin.

It provides skin brightening benefits by reducing the amount of skin pigment by almost 80%.

Helps boost collagen production and, in fact, more so than L-ascorbic acid. This is because one of the limiting factors with L-ascorbic acid is its inability to penetrate deeper into the dermis.

Tetrahexyldecyl Ascorbate also stimulates the production of glycosaminoglycans such as hyaluronic acid that are naturally present in skin and so help to hydrate skin as well as plump skin cells. Levels of these glycosaminoglycans decline with age and this may account for some of the changes that occur with our skin as we age.

Tetrahexydecyl ascorbate is stable, safe, effective and suitable for all skin types including sensitive skin.

Garden of Wisdom’s C-Deep Vitamin C Serum is, in my opinion, one the best vitamin C serums currently available on the market. This vitamin C serum contains a therapeutic strength of Tetrahexyldecyl ascorbate which is suspended in Squalane, a light oil that is easily absorbed into skin.

Included in this vitamin C serum is Thiotane®, a powerful antioxidant amino acid that occurs naturally in the body. It is found in high concentrations around cells prone to free radical damage helping to protect the genetic material and the mitochondria, which are the energy factories within our cells. These energy factories are absolutely vital for cell regeneration and repair.

Garden of Wisdom C-Deep Vitamin C Serum provides a potent blast of vitamin C to your skin without any irritation. Like all Garden of Wisdom serums, this vitamin C serum is clean, non-toxic, free from alcohol and silicones.

Vitamins to take in your 50s

It is important that you take the correct vitamins and supplements in your 50s to boost your health and vitality. The choice of supplements is overwhelming and the advice given can be confusing. Looking after your health is important at any age and never more so than in your 50s. In our 50s, we do not digest foods the way we did when we were younger and supplements can play an important role in filling any nutritional gaps.

Which vitamins should I take?

  • I believe that there are some fundamental supplements that are worth taking and these include:
  • A quality vitamin and mineral supplement
  • Probiotics because the digestive system gets sluggish with age
  • Omega 3 essential fatty acids since most of us do not get sufficient amounts
  • A calcium supplement to prevent brittle bone disease
  • A sublingual form of Vitamin B-12

Surviving February

surviving-february

Depending upon where you are in the world, February can be a difficult month. Although the days are getting longer, they appear to be grey, dark and cold. February is considered so bleak that scientists have actually labelled a syndrome called the February Slump.

But we can all endure February with some slight changes that can make a positive difference.

Light some candles and take a hot bath. A bath can be a ritual and should never be a task. It should be something that you enjoy experiencing rather than on your ‘to do’ list such as washing dishes and reading on the internet. Magnesium flakes will work wonders to relax the mind and the body and one’s that I often reach out for are Better You’s Magnesium Oil Original Flakes.

Add some spices to your dinner. When the temperature drops, introduce certain spices such as ginger and turmeric into your food. These spices warm our bodies from the inside and at the same time provide numerous benefits which include aiding digestion and enhancing circulation. Read More…

The Incredible Benefits Of Broccoli Sprouts

Fresh Broccoli Stems

We all know that eating vegetables is a healthy choice and provide profound benefits to the body. Unfortunately, numerous studies indicate that only one in ten of us actually achieves the recommended daily intake of approximately 800 grams a day of a mixture of fruits and vegetables.

Whilst all types of vegetables are going to be beneficial, there is one group that scientists believe contribute significantly to overall health due to their unique nutrition content – the Brassica family; commonly known as cruciferous vegetables. These include broccoli, Brussel sprouts, kale, cabbage, cauliflower, radish and turnips.

Aside from their nutritional content, scientists have found a compound that makes these vegetables so important called Sulforaphane (also called SFN). Read More…
