Why Take Collagen?

Collagen makes up 25-35% of the entire body's protein content. This structural protein is responsible for building the connective tissue throughout the body, including your skin, muscle and bones.

It has been gaining rapidly in popularity around the world for its properties and benefits to skin, hair and nails.

Sadly as we age, our ability to produce collagen worsens severely. This slow down in collagen production begins in our 20s and it has been revealed that by our 50s, we have lost up to a third of it.

With collagen making up 80% of our skin, it's no wonder that as we age, we begin to see signs of ageing, dry skin and wrinkles. Not just that, but the loss of collagen can cause issues related to joints, heart, bones and muscles. A good quality collagen supplement may be recommended to support these various issues.

Why Is Marine Collagen Most Effective?

Studies have shown that taking a high quality collagen supplement may be an effective way to nourish the skin. But with so many types of collagen, which should you take? The answer is hydrolysed marine collagen.

Hydrolysed marine collagen, also known as 'Type 1', is made of peptides which come from fish and their scales. The process of hydrolysing it is indended to give it better absorption into the bloodstream. This type of collagen is also the most plentiful in the body, so it makes sense to use a supplement that contains the type you need the most. In addition, it is also more sustainable as it is sourced from parts of fish which are typically unused.

Some clinical studies have shown that hydrolysed marine collagen supports healthy skin elasticity and helps support hair and nails. Not just that, it may help with joint health and support healthy weight management. It's no surprise collagen supplements are surging in popularity.

Benefits of High Quality Collagen

A high quality collagen supplement is an efficient and cost-effective way of delivering nutrients that may be needed as we age. With the right supplement, you may feel a difference from as early as 2-3 weeks.

Supports Hair & Nail Growth

Collagen may help add shine & lustre to hair while strengthening nails and supporting healthy growth.
Supports Hydration of Skin

Increasing your collagen intake may help hydrate your skin and support overall skin health which deteriorates as we age.
Discourages Wrinkles & Dryness

By increasing elasticity and hydration, collagen may reduce wrinkles and dry, flakey skin.
Supports Weight Management

Some research shows that an increase in collagen may support in slowing development of adipocytes, also known as fat cells.

What To Look For?

Collagen Supplements are NOT all the same. It’s important to choose quality, proven formulas from trusted brands to see real benefits.

Potent Doses of Collagen A high quality collagen supplement should contain a potent dose of collagen. We recommend looking for around ~1000mg of Marine Collagen (Type 1)
Includes Hyaluronic Acid This equally beneficial ingredient is a natural substance that is found in the eyes and joints. Studies have shown that it can work with collagen to prevent new wrinkles, reduce fine lines and reverse sun damage.
Quality Ingredients Choose a supplement that contains no artificial or unnecessary ingredients. It is equally important to choose a formula that combines natural, proven ingredients such as Vitamin C and Turmeric in combination with Collagen.
Money-Back Guarantee It is important to buy from brands that stand behind their product. Without a money back guarantee, you could lose your money and end up with an ineffective product. It is recommended to look for brands that offer a 30 or 60 day guarantee.

What Should I Avoid?

Poor Formulations & Doses As stated before, not all collagen supplements are equal. It is recommended to stay away from supplements that offer too low of a dose (less than 1000mg of Collagen). We also recommend purchasing from UK manufactured formulas to guarantee the quality of the ingredients.
Artificial Reviews Watch out for product listings on Amazon and other marketplaces. In many cases, these reviews are fake and only made to increase their visibility. Purchase from brands that have trusted websites and that produce their products in the UK.

The Bottom Line

THE BOTTOM LINE

After reviewing this collagen peptide supplement by Dr Mercola, we noted a few deficiencies and irregularities.

While this is an inexpensive supplement, which may be suitable for those looking for a budget option, it does contain some serious deficiencies. Firstly, it contains carbohydrates and requires 3 capsules per day. In addition, some ingredients are sourced from outside the UK, which is not ideal.

Beyond this, it lacks a number of recommended minerals alongside Collagen such as Vitamin C & E as well as Hylauronic Acid and Turmeric. Overall, this formula falls short on a number of factors but the plus side is that it uses sustainable traceable and sustainable sources of collagen.

OVERALL GRADE

Pros

Formulated with Vitamin C & E
Manufactured in the UK

Cons

Low dosage of Collagen: 750mg
Not suitable for Vegans
No money-back guarantee

The Bottom Line

Nuearth's Collagen Formula comes with a few benefits, such as the additional of important minerals (Vitamin E, C). They also include Hyaluronic Acid which is recommended.

However, while the formula contains the recommended ingredients, it falls drastically short on the recommended doses. For example, the collagen content is just 350mg, whereas 1000mg is normally recommended. When factoring doses of ingredients, this product is poor value for money and may lead to mixed results.

Finally, it also lacks some key antioxidants such as Turmeric or Sea Kelp. Overall, we recommend if you are already taking an existing skin supplement that contains a dose of Collagen.

OVERALL GRADE

TOTAL RANKING

Pros

Formulated with Vitamin C
Made in the UK
Fast Delivery

Cons

Low dosage of collagen
No money-back guarantee
Not suitable for vegetarians
Can only buy online
No customer reviews/feedback

The Bottom Line

Healthy Mood's Collagen Formula is a budget-friendly supplement. Its inexpensive and good for those looking for a cheaper, yet less effective option.

While it contains Collagen and Vitamin C + B, it fails to include more expensive ingredients such as Hyaluronic Acid or antioxidants such as Turmeric.

However its effectiveness is mostly harmed by the lower doses of Collagen, which clocks in at just 400mg. This is 60% lower than the recommended dose of 1000mg of Marine Type 1 Collagen. Overall, we would recommend this only if on a very limited budget.
