4 signs of a vitamin C deficiency (And How Collagen Can Help)

4 Signs of Vitamin C Deficiency (And How Collagen Can Help)

Vitamin C is a vital nutrient that must be consumed regularly as part of a healthy diet. Unlike some nutrients, your body cannot produce or store vitamin C, which means you need a consistent daily intake to maintain optimal health.

Having a poor diet, smoking or certain health conditions can increase your likelihood of being vitamin C deficient. Many people have low vitamin C levels but don't recognise the signs. Below we explore the 4 most common signs of vitamin C deficiency and explain why this nutrient is so crucial for collagen production and overall health.

Sign 1: Rough, Bumpy Skin

As vitamin C is an essential component in collagen production, many people who suffer from vitamin C deficiency find their skin becomes rough, bumpy and uneven in texture.

A condition called keratosis pilaris can develop due to vitamin C deficiency, which causes small, rough bumps to form on the arms, thighs and legs. These bumps occur when keratin builds up in hair follicles, creating a characteristic "chicken skin" appearance. While keratosis pilaris can have other causes, vitamin C deficiency is a contributing factor because inadequate collagen production affects skin structure and follicle health.

Why This Happens

Without sufficient vitamin C, your body cannot produce the collagen needed to maintain smooth, healthy skin structure. Collagen provides the scaffolding that keeps skin firm, plump and even. When collagen production declines, skin texture deteriorates and becomes more prone to roughness and irregularities.

Sign 2: Easy Bruising

If you're beginning to find you bruise more easily than usual, it may be a sign you're lacking vitamin C. Poor collagen production causes weaker blood vessels, and when you have a vitamin C deficiency, blood vessels are more likely to rupture under the skin and cause bruising.

You might notice bruises appearing from minor bumps that wouldn't previously have caused visible marks, or bruises that are larger and more colourful than expected. The bruises may also take longer to heal and fade.

The Connection to Collagen

Blood vessel walls are made largely of collagen. When vitamin C levels are insufficient, the structural integrity of these blood vessels weakens, making them fragile and prone to breaking. Even minor pressure or impact can cause the vessels to rupture, leading to the characteristic purple or blue marks of bruising.

Sign 3: Corkscrew or Ingrown Body Hair

As vitamin C deficiency results in defects to the protein structure of hair, one unusual but distinctive sign is body hair growing in bent, coiled or corkscrew shapes rather than growing straight.

Hair may also become more prone to damage, breakage and falling out more easily. The hair shaft itself may appear weakened, brittle or oddly shaped. This occurs because collagen is essential not just for skin health but also for the proper formation and strength of hair follicles and the hair shaft structure.

Why Hair Is Affected

Hair follicles require adequate collagen in the surrounding dermal tissue to produce healthy, strong hair. When vitamin C deficiency impairs collagen synthesis, the follicles cannot function optimally, leading to structural abnormalities in the hair that grows from them.

Sign 4: Dry, Tired-Looking Skin

Vitamin C is an essential nutrient that ensures the skin remains healthy and protected from environmental pollutants. For this reason, vitamin C deficiency can cause your skin to look dry, tired, dull and prematurely wrinkled.

Your skin may also become more vulnerable to damage from pollutants, UV rays and cigarette smoke. The protective antioxidant properties of vitamin C help neutralise free radicals that cause oxidative stress and premature ageing. Without adequate vitamin C, this protection is compromised.

The Dual Role of Vitamin C

Vitamin C plays two crucial roles in skin health. First, it's required for collagen synthesis, which maintains skin structure, firmness and hydration. Second, it acts as a powerful antioxidant that protects skin cells from environmental damage. When deficient in vitamin C, you lose both benefits simultaneously, leading to accelerated visible ageing.

Who Is at Risk of Vitamin C Deficiency?

Certain groups are at higher risk of vitamin C deficiency:

• Smokers - smoking depletes vitamin C levels significantly
• People with limited diet variety or who avoid fruits and vegetables
• Older adults, particularly those with poor appetite or restricted diets
• People with malabsorption conditions like Crohn's disease or ulcerative colitis
• Those with alcohol dependency
• People undergoing dialysis

For women over 40, maintaining adequate vitamin C becomes increasingly important as natural collagen production declines with age. Vitamin C deficiency compounds this natural decline, accelerating visible signs of ageing.

How Much Vitamin C Do You Need?

The recommended daily allowance (RDA) for vitamin C is 40mg in the UK for adults. However, many health experts suggest higher intakes (75-90mg) for optimal health, particularly if you smoke, are under stress, or want to support skin health and collagen production.

Vitamin C is water-soluble, which means your body doesn't store it. Any excess is excreted in urine, so you need consistent daily intake rather than occasional large doses.

What's the Easiest Way to Include Vitamin C in Your Diet?

Whether you're experiencing any of the above symptoms or want to support healthy skin, hair and collagen production, there are two main approaches:

Food Sources

Vitamin C-rich foods include citrus fruits (oranges, lemons, grapefruit), berries (strawberries, blackcurrants), kiwi fruit, bell peppers, broccoli, Brussels sprouts, tomatoes and leafy greens. Eating a variety of these foods daily ensures adequate vitamin C intake.

Supplementation

For many people, particularly those taking collagen supplements, combining vitamin C and collagen in one supplement makes sense. This is because vitamin C is essential for your body to utilise the collagen peptides you're consuming.

Kollo Premium Liquid Marine Collagen contains 80mg of vitamin C (100% RDA) in every sachet, alongside 10,000mg of marine collagen peptides. This ensures your body has both the building blocks (collagen peptides) and the essential cofactor (vitamin C) needed for optimal collagen synthesis.

The formula also includes B vitamins (B1, B5, B6, B12) and l-lysine, which further support collagen production and overall skin health.

Why Vitamin C and Collagen Work Better Together

Taking collagen supplements without adequate vitamin C is like having building materials but no workers to assemble them. Vitamin C is the essential enzyme cofactor that allows your body to synthesise new collagen from the amino acids provided by collagen peptides.

Research shows that combining vitamin C with collagen supplementation produces superior results for skin elasticity, hydration and wrinkle reduction compared to either nutrient alone. This synergistic effect is why quality collagen supplements include vitamin C in the formula.

How to Overcome and Prevent Vitamin C Deficiency

• Eat a varied diet rich in fruits and vegetables daily
• If you smoke, consider quitting - or increase vitamin C intake to compensate for depletion
• Take a daily supplement that combines vitamin C with collagen for comprehensive support
• Be consistent - vitamin C isn't stored, so daily intake is essential
• Choose liquid supplements for superior absorption compared to tablets
• Monitor your skin, hair and overall health for improvements over 8-12 weeks

The easiest way to overcome and prevent vitamin C deficiency while supporting collagen production is by taking Kollo liquid collagen daily. Each tropical-flavoured sachet provides everything your body needs to synthesise collagen effectively - the collagen peptides, the vitamin C cofactor, and supporting B vitamins and amino acids.
