Most of us think of oranges and chewable tablets when it comes to vitamin C. When searching for a vitamin C supplement, we will encounter conventional forms such as capsules, pills, and powders. However, there is a highly effective form of vitamin C that deserves our attention: liposomal or liquid vitamin C. This article explores the many health benefits of consuming a spoonful of this potent, highly bioavailable, antioxidant, liquid vitamin C.

COMPREENDER A VITAMINA C

Vitamin C, also referred to as ascorbic acid, is an essential water-soluble vitamin that our bodies cannot reproduce. Unlike fat-soluble vitamins, water-soluble vitamins are not stored in the body. Vitamin C is one of the most studied and understood antioxidants of which around 80-90% is derived from our food. Foods rich in vitamin C are Kakadu plums (an Australian native superfood with the highest known concentration of vitamin C), acerola cherries, blackcurrants, guavas, bell peppers, kiwis, strawberries, oranges, papayas, broccoli, tomatoes, kale, and snow peas.

Vitamin C diminishes rapidly when exposed to light; during extended storage or when heated and because of its water-soluble nature it can seep into the cooking liquid and be lost.

Vitamin C is best absorbed on an empty stomach for optimum absorption and an intake of 75 mg for women and 90 mg for men is recommended.

O QUE É A VITAMINA C LÍQUIDA?

Liquid vitamin C supplements are a specialised form of vitamin C (a water-soluble vitamin also known as ascorbic acid), that utilises liposomes for enhanced absorption.

The delivery system known as liposomes has been in existence since the mid-1960s and is continuously evolving. They were first used as a drug carrier in the mid-1990s due to their similarity to body cells. Liposomes have been primarily utilised for vaccinations, gene therapies, and orally administered medications. It was specifically created for maximum absorption and optimal bioavailability.

COMO É QUE A VITAMINA C LÍQUIDA FUNCIONA?

Our intestines can’t handle more than 200 mg of vitamin C before digestive problems arise. The solution would be to get a vitamin C shot that goes directly into your bloodstream without the needles.

A investigação sugere que a vitamina C lipossómica produz níveis mais elevados de vitamina C em circulação no organismo do que a vitamina C em pó, não lipossómica.

Eis como funciona a vitamina C líquida.

Formação de lipossomas:

• Os lipossomas são pequenas esferas lipídicas (gordura) compostas por fosfolípidos, semelhantes aos blocos de construção das membranas celulares.
• Os lipossomas são hidrofílicos (gostam de água) e hidrofóbicos (têm medo de água).
• As esferas lipídicas encapsulam as moléculas de vitamina C, criando bolsas protectoras para as mesmas.
• A estrutura lipossómica apresenta um centro oco, proporcionando um ambiente seguro para as vitaminas.

Absorção reforçada:

• Devido à sua composição semelhante à das membranas celulares, os lipossomas são absorvidos e ligados mais eficazmente.
• O consumo de vitamina C líquida com lipossomas actua como um recipiente ideal para fornecer vitaminas ao seu corpo.
• A estrutura lipossómica protege as vitaminas dos efeitos corrosivos do ácido gástrico no estômago.

Proteção no estômago:

• Os lipossomas funcionam como bolhas protectoras para cada molécula de vitamina C.
• Assim, a vitamina C permanece protegida das enzimas digestivas altamente ácidas do estômago.
• Chega em segurança ao intestino, onde pode entrar na corrente sanguínea.

Biodisponibilidade melhorada:

• O sangue é o principal veículo para a vitamina C atingir os tecidos-alvo. Ao contrário dos comprimidos tradicionais de vitamina C que precisam de se dissolver, a vitamina C líquida com lipossomas entra mais rapidamente na corrente sanguínea.
• The bioavailability of liposomal vitamin C is significantly higher compared to standard tablets.
• Isto significa que o seu corpo pode absorver e utilizar mais nutrientes de forma eficaz.

The scientific process is termed Liposomal Encapsulation Technology (LET) and can be investigated in more detail in our other article What are Liposomal Supplements and How Do They Work?

PORQUE É QUE A VITAMINA C É BENÉFICA PARA O NOSSO ORGANISMO?

Scurvy, a chronic condition resulting from a significant vitamin C deficiency (ascorbic acid) in one's dietary intake, is a well-recognised health concern. Today Scurvy occurs mostly when people are malnourished. Symptoms such as weakness, anaemia, gum disease, and skin problems are evident. But why does this occur?

This is because vitamin C is necessary to make collagen, an important component in connective tissues essential for structure, growth and healing in the body. In addition, it is necessary for proper blood vessel function and aids in the absorption of iron, which the body requires to produce red blood cells.

Let's explore the key benefits of liquid vitamin C for our bodies.

A vitamina C líquida actua como um poderoso antioxidante.

Vitamin C may reduce the risk of chronic diseases by protecting cells from harmful molecules called free radicals. It increases blood antioxidant levels by up to 30% which helps fight inflammation and reduces the risk of heart conditions.

A vitamina C líquida pode ajudar a baixar a tensão arterial.

Vitamin C may help lower blood pressure in healthy adults and those with high blood pressure. It relaxes blood vessels, reducing blood pressure levels. Studies show that a vitamin C supplement reduced systolic blood pressure by 3.8 mmHg and diastolic blood pressure by 1.5 mmHg in healthy adults.

A vitamina C líquida diminui o risco de doenças cardíacas.

A review of 9 studies with 293,172 participants, found that taking at least 700 mg of vitamin C daily led to a 25% lower risk of heart disease after 10 years compared to not taking a supplement.

A vitamina C líquida reduz os níveis de ácido úrico no sangue.

Gout, a form of arthritis, causes painful inflammation and joint swelling. A comprehensive review of 13 studies involving gout patients revealed that long-term use of a vitamin C supplement significantly lowered blood uric acid levels compared to a placebo. This reduction in uric acid levels was associated with a decreased risk of recurrent gout attacks.

A vitamina C líquida previne a carência de ferro.

Vitamin C enhances the absorption of non-heme iron (found in plant-based foods) in the intestines, aiding individuals who follow vegetarian or vegan diets or those with an iron deficiency. The intake of 100 mg of vitamin C can potentially enhance iron absorption by 6%.

A vitamina C líquida apoia o sistema imunitário.

Vitamin C supplementation is primarily taken to support the immune system. It does this by promoting the production and function of white blood cells (lymphocytes and phagocytes), which helps the body protect itself from infections.

Vitamin C appears to reduce the severity of colds and recovery time by 8% in adults and 14% in children. Read more about how you can boost your immune system in our article on high-dose vitamin C supplementation.

A vitamina C líquida é essencial para a saúde da pele.

Vitamin C is actively transported to the skin, where it can act as an antioxidant and help strengthen the skin’s barriers. It is essential for collagen production, which is the main structural protein in connective tissue. We often overlook the fact that connective tissue is a crucial component of organs such as the heart, lungs, skin, liver, and kidneys.

In our daily workouts, strenuous training can cause tears in the connective tissue. Vitamin C could help accelerate the recovery process of such injuries and protect our joints over time.

Collagen is also responsible for maintaining skin plumpness and hydration. As we age, a decrease in collagen and vitamin C levels contributes to skin ageing.

A vitamina C líquida desempenha um papel na cicatrização de feridas.

A investigação indicaram que a ingestão de vitamina C pode reduzir o tempo que as feridas demoram a cicatrizar. Acima discutimos como a vitamina C aumenta a síntese de colagénio, um componente chave dos tecidos conjuntivos e fornece o quadro estrutural para a reparação de feridas.

Quando uma ferida está a cicatrizar, células especiais chamadas fibroblastos produzem colagénio, uma parte vital do tecido que ajuda a ferida a fechar. Nas fases iniciais da cicatrização, as células inflamatórias libertam citocinas que fazem com que estas células se desloquem para o local da ferida. Este processo não só fortalece a ferida como também aumenta a sua resistência à tração, o que acaba por conduzir a um melhor fecho da ferida.

A vitamina C líquida protege as funções cognitivas e a memória.

The brain contains one of the highest concentrations of vitamin C in the body, emphasising its importance in maintaining brain health. It acts as a co-factor in the synthesis of neurotransmitters like norepinephrine and dopamine, which are crucial for mood regulation, memory formation, and cognitive function

Vitamin C also plays a role in the synthesis of myelin, a fatty substance that speeds up the transmission of electrical signals in the brain. Proper myelination is essential for the efficient functioning of the brain.

Low levels of this vitamin C have been associated with impaired thinking and memory. Dementia is a general term used to describe symptoms of poor thinking and memory and it affects over 35 million people worldwide, typically occurring among older adults.

Studies suggest that oxidative stress and inflammation near the brain, spine, and nerves (collectively known as the central nervous system) can increase the risk of dementia. Furthermore, several studies have indicated that people with dementia may have lower blood levels of vitamin C.

A vitamina C líquida ajuda a perder peso.

When you have sufficient vitamin C, your body is more likely to burn fat during exercise. Studies show people with adequate vitamin C levels oxidise 25% more fat during physical activity than those with low vitamin C levels. Vitamin C acts as a cofactor (like a helper) in certain processes related to fat metabolism.

Vitamin C contributes to energy and protein metabolism, helping to boost your metabolism. It assists in making L-carnitine, a molecule that helps transport fatty acids to be oxidized in the cells. When you have sufficient carnitine, fat molecules move from storage to the place where they’re “burned” for energy. Lack of carnitine may lead to fatigue and weight loss problems.

Feeling tired is an early sign of vitamin C deficiency. So, maintaining adequate vitamin C levels is essential for overall health.

Vitamin C's antioxidant properties, help reduce oxidative stress in the body which may contribute to boosting the metabolism.

A vitamina C líquida pode ajudar a saúde dos olhos.

Although more investigative studies are needed, we have established vitamin C's role as an antioxidant for cells in the retina and macular region of the eye. When taken with other essential nutrients, Vitamin C may help protect against cataract formation (a clouding of the lens of the eye) and slow the progression of age-related macular degeneration (AMD), which causes people to lose their central vision.

A vitamina C líquida pode proteger a saúde dos ossos.

A 2021 research review found that long-term vitamin C supplementation was associated with approximately 3% higher bone mineral density in women compared to those who did not supplement.

VITAMINA C LIPOSSÓMICA vs VITAMINA C TRADICIONAL

When comparing liposomal or liquid vitamin C to traditional pill form, consider absorption and convenience. Liquid vitamin C provides greater benefits due to high bioavailability and fast delivery, while pill forms are easier to transport and less expensive. However, liquid vitamin C has a shorter shelf life and requires refrigeration, increasing the long-term cost. Now let's examine the benefits of a liquid vitamin C.

Biodisponibilidade e taxa de absorção

• Vitamina C tradicional: Os suplementos são muito utilizados, mas a sua taxa de absorção é mais lenta e normalmente limitada a cerca de 12-14%. Ao contrário dos líquidos, os comprimidos têm uma estrutura química sólida, necessitando de mais tempo para se dissolverem do que os líquidos. O ácido estomacal e a decomposição enzimática podem dificultar a absorção adequada.
  
  
• Liquid Vitamin C: Supplements use a different approach as it is encapsulated within lipid-based vesicles, known as liposomes which protect the vitamin C molecule from gastric challenges.
  
  Several scientific studies have found evidence that the liposomal delivery system of vitamins helps more of the vitamin get into the bloodstream resulting in a much higher absorption compared to more traditional supplements. The bioavailability of liposomal vitamin C is only exceeded by intravenous (IV) vitamin C.
  
  

Tolerabilidade, conveniência e dosagem

• Traditional vitamin C: Supplements in capsule or pill form may excuse the pun be hard to swallow. This form is normally swallowed with water and typically are flavourless.
  
  Tablets and capsules may also contain additives and stabilisers that are sometimes not found in liquids.
  
  Lowering dosages is trickier with capsules and pills due to their solid form and thus those that are highly sensitive to the vitamin are more likely to experience stomach upsets.

• Liquid vitamin C: Vitamin C as a liquid can be consumed directly or mixed into beverages, making it a convenient option to incorporate into your daily routine. Most of them have a pleasant fruity flavour.
  
  One of the greatest advantages of the liquid form is that it is perfect for those who have difficulty swallowing pills and is ideal for children, the elderly or those who may struggle with solid supplements.
  
  Liquid vitamin C tends to be gentler on the stomach and can be a better option for those with sensitive digestive systems. In terms of incremental dosing, it can be taken in low doses, which may limit side effects.

EFEITOS SECUNDÁRIOS DA VITAMINA C

According to the National Institute of Health (NIH), the recommended dosage of vitamin C is 75 mg/day for women over 19 and 90 mg/day for men over 19. Generally, 1000-2000 mg/day should afford you the general health benefits of vitamin C.

Existem muito poucos efeitos secundários conhecidos da ingestão de vitamina C hidrossolúvel, uma vez que o corpo expulsa o que não absorve.

Doses grandes, superiores a 2000 miligramas por dia, podem causar diarreia, náuseas, cólicas abdominais e outros problemas gastrointestinais. Não ultrapassar esta quantidade sem consultar um médico. As pessoas que tomam suplementos elevados de vitamina C correm o risco de sofrer uma sobrecarga de ferro (hemocromatose) ou têm tendência para a formação de cálculos renais devem ter cuidado com a ingestão de vitamina C.

Antes de tomar qualquer suplemento, consulte o seu médico se tiver alguma doença pré-existente. Os suplementos de vitamina C podem também interagir com determinados medicamentos para doenças cardíacas e cancro.

COMO ESCOLHER O MELHOR SUPLEMENTO LÍQUIDO DE VITAMINA C?

Faça a sua pesquisa e compre um suplemento lipossómico de alta qualidade, certificando-se de que estes requisitos são cumpridos:

• Contém vitamina C e fosfolípidos (como a fosfatidilcolina)?
• Evitar os ésteres lipossolúveis de vitamina C, como o palmitato de ascorbilo, o oleato de ascorbilo ou o ascorbato de cetilo, pois podem não oferecer vantagens significativas em relação à vitamina C normal.
• Procurar a fonte de vitamina C.
• Compre apenas produtos cientificamente testados.
• Escolha suplementos com um mínimo de aditivos para que os benefícios da vitamina C lipossomal sejam tão diretos quanto possível.
• Assegurar que o suplemento não é OGM e não contém soja, glúten e lacticínios
