Why Take Niacinamide & Collagen?

When it comes to skin supplements, Niacinamide & Marine Collagen are the secrets to real results.

Niacinamide is a form of Vitamin B. It is a true multitasker, from boosting hydration to protecting the skin from environmental damage, it offers a wide variety of benefits. It penetrates your skin and helps renew your complexion from within.

Collagen is a type of protein that plays an important role in building and supporting many tissues, from bones and cartilage to skin and hair. Collagen makes up over 80% of our skin, so by increasing your intake of Collagen, you can preserve skin elasticity, hydrate and prevent signs of aging.

As we age and through the elements, our skin begins to lose its stretchiness, resulting in wrinkles, spots and other imperfections. The same can be caused by stress, fatigue or lack of sufficient sleep. This is where these two ingredients become absolutely crucial.

How Do They Work?

Niacinamide is a water-soluble vitamin that is incorporated into many topical skincare formulations. It works with the natural substances in your skin to help visibly minimize enlarged pores, regulate oil production, improve uneven skin tone and soften fine lines and wrinkles. Best of all - it helps boost your natural collagen production and may prevent skin cancer and acne.

Ingesting marine collagen repairs skin collagen and elastin protein fibers and produces a significant thickening of the outer skin surface (epidermis). It does this partially by allowing more absorption of calcium, phosphorus and other minerals. Collagen is absolutely crucial to healthy skin, and by taking Type 1 Marine Collagen, you can help your skin restore itself and decrease signs of damage.

Benefits of High Quality Skin Complex

Supplements can be a very effective and inexpensive method of restoring your skin. It also comes with a lot less side effects when compared to expensive clinical treatments. By choosing the right skin supplement, you could see a difference from just 2-3 weeks. A high quality supplement containing Niacinamide & Marine Collagen could:

  • Hydrate Skin & Reduce Wrinkles

    As we age into our late 20s, our collagen production slows down significantly. This causes your skin to dehydrate and lose its elasticity, which results in wrinkles and other imperfections. Niacinamide is very effective for re-hydrating the skin while increasing collagen intake helps to make the skin stretchier.

  • Encourage Hair & Nail Growth

    Niacinamide has a vital role in growing long and strong hair due to its circulation- boosting properties. It enhances the appearance and feel of hair, by increasing body, suppleness, sheen, meanwhile collagen prevents brittleness of your nails.

  • Helps With Weight Management

    Studies have shown that Type 1 Marine Collagen may reduce the development and accumulation of adipocytes, or fat cells.

  • Reduces Inflammation & Helps Joint Pain

    Research shows that Niacinamide & Collagen can be very effective in treating joint pain, stiffness and arthritis. Collagen is one of the main compounds in cartilage, which when worn down, leads to chronic conditions. By supplementing with Niacinamide & Collagen, you may slow down this wearing and ease joint pain.

Is Hyaluronic Acid Also Important?

Hyaluronic Acid is an ingredient that is generally seen in very high quality skip supplements. Hyaluronic acid is a substance that is naturally present in the human body. It is found in the highest concentrations in fluids in the eyes and joints.

  • Hylauronic Acid is used as a humectant - a substance that helps the skin hold onto moisture. It helps hydrate the outer layers of skin, thereby improving the skin's appearance
  • Studies show that it can help in tissue regeneration, which can help improve dark circles and lines around the eye. It also helps to lubricate joints, which can help reduce pain in joints and increase flexibility.
  • Alongside Niacinamide, HA can help promote further natural collagen production in the body.

What To Look For?

  • 250mg-300mg Niacinamide A high quality supplement should include Niacinamide, a unique form of B3 Vitamin. This ingredient has been shown to vastly improve the appearance of the skin, by hydrating and locking in moisture and rebuilding healthy skin cells. High quality supplements normally contain 250-300mg of Niacinamide.
  • 200-250mg Type 1 Collagen Type 1 Marine Collagen is the most effective form of collagen to take if you’re looking to replenish your skin. Not only does it help rebuild your skin, it’s also good for strengthening your nails and helping you grow stronger, thicker hair. Type 1 collagen is most abundant in Marine Collagen.
  • Hyaluronic Acid This is the key molecule involved in skin moisture and it helps bind water to collagen. That is why it is crucial to look for supplements thatcombine both HA and Collagen for truly effective results.
  • Additional Ingredients High quality skin supplements shouldn’t just stop at Niacinamide, Collagen and Hyaluronic Acid. It is highly recommended that they include further accessory ingredients to provide a well-rounded skin solution. Keep an eye out for beneficial extras such as: Vitamin C, Vitamin E, Turmeric and Biotin.
  • 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 30-60 day guarantee.

What Should I Avoid?

  • Poor Formulations & Doses Stay away from formulas that only focus on 1 main ingredient. Your skin is made up of many different building blocks - that is why customers often report poor results when they buy pure Collagen supplements. High doses of Collagen on their own will not deliver strong results. It is important to combine well-balanced doses of multiple key skin-boosting 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. Buy from brands that have trustworthy-looking websites and that make their products in the UK.

Cons

  • Sometimes Out of Stock

The Bottom Line

Of all Niacinamide, and indeed all skin-focused supplements, Bettervits Niacinamide Complex is one of the most effective formulas in the market.

The reasoning behind this is due to a combination of 3 core ingredients which are used in high-end skincare brands such as La Mer, as well as other well-known brands such as The Ordinary. This supplement contains Marine Type 1 Collagen, Hyaluronic Acid and Niacinamide, all in potent doses.

This makes Bettervits unique as most competitors generally sell these formulas separately, such as Collagen-only supplements. While taking Collagen on its own may produce some benefits, the combination of these 3 skin care staples produce superior benefits and results when it comes to treating your skin. Furthermore, it also includes a dose of Turmeric which is a power anti-oxidant and can help reduce signs of fatigue to the skin.

Bettervits offers a hassle-free money back guarantee of 60 days and free shipping is available. This is hands down one of the best skin supplements you can find in the market.

The Bottom Line

Second to Bettervits, is HealthAid's Vegan Niacinamide supplement.

It contains a good dosage of niacinamide, however, it falls very short due to the lack of additional ingredients such as Collagen and Hyaluronic Acid. Furthermore, these are tablets which can sometimes be harder to swallow.

There are good reviews of this product, but there is no money back guarantee and most of the reviews are related to the fast delivery rather than the effective results. Due to the fact that this is a Niacinamide-only supplement, it may cause flushing of the skin.

The Bottom Line

This powdered supplement contains just 100mg dosage of Niacinamide, making it a poor dosage, however it is a viable method for those who prefer not to swallow capsules.

It is also suitale for vegetarians and offers free shipping, but no money back guarantee, making it potentially risky in case it does not work for you.

It also lacks additional, important ingredients such as Marine Collagen and Hyaluronic Acid.

Jarrow's Niacinamide supplement contains a solid dose at 250mg and good value for money.

However, it is let down due to the lack of Marine Collagen and Hyaluronic Acid, two ingredients whcih are essential to delivering robust results for your skin.

The bright side is this product, due to a high quality source of Niacinamide, it also does not cause flushing, which is a risk seen amongst other singlular Niacinamide supplements see.

The Bottom Line

This Naicinamide supplement contains just 50mg of Niacinamide, making it one of the lower doses seen on the market.

This may be good if you already have very healthy skin and are simply looking to maintain, however it results in poor value for money, particularly when compared to similarly-priced products that have numerous health benefits and contain better dosages and more vitamins.

Beyond this, there is free shipping available, but no money back guarantee, which is something our readers normally look for in case supplements don't work for them.
