Signs You Might Need a Collagen Supplement

Sagging skin or fine wrinkles as your skin loses elasticity
Brittle hair that snaps, or nails that break or split easily

Cuts, bruises and other skin injuries take longer to heal

The Benefits of Collagen Supplements

Improve Skin Elasticity and Hydration

You can help maintain your skin's firmness and elasticity by replenishing collagen levels. This can reduce wrinkles and promote a more youthful and hydrated complexion.

Strengthen Hair and Nails

Collagen provides essential amino acids that support the structural integrity of hair and nails, making them less brittle and more resistant to breaking.

Support Joint Health and Mobility

By supporting cartilage regeneration and reducing joint inflammation, collagen supplements can help alleviate joint pain, improve flexibility, and prevent the progression of degenerative joint conditions such as osteoarthritis.

Support Bone Density and Strength

Collagen makes up 90% of the organic matrix in our bones, and keeps the vital minerals in place. Collagen supplements may help maintain bone strength, reduce the risk of fractures, and support overall bone health, especially as we grow older.

Promote Muscle Recovery and Growth

Rich in glycine, an amino acid crucial for muscle repair, collagen supplements can help speed up recovery from exercise-induced injuries and promote muscle growth and endurance.

Improve Digestion

Collagen contains glutamine, which helps maintain the integrity of the gut lining. This can reduce symptoms of leaky gut syndrome.

Reduce Cellulite and Stretch Marks

By strengthening the dermis and improving skin elasticity, collagen can help reduce cellulite and stretch marks, leading to smoother, firmer-looking skin.

Boost Wound Healing and Tissue Repair

Collagen supplements can accelerate the repair of damaged skin, reduce scarring, and promote faster recovery from cuts, wounds, and surgical incisions.

Collagen Supplements Are NOT All Created Equal

Before you start shopping around for some collagen, there are some key things you need to know. Make the right choice so you don't waste your money on a product that fails to deliver results.

Your Collagen Supplement Checklist

Choose

Hydrolysed collagen peptides

When collagen is hydrolysed, it means that the proteins have been broken down into smaller molecules called peptides. This makes it easier for the body to absorb it into the bloodstream.

The right dose - 1000mg daily

Collagen supplements work by triggering your own body's production of collagen, drawing in nutrients from many of the foods you eat. An effective dose to do this is around 1000mg a day.

Coenzyme Q10 for deeper benefits

Providing antioxidant protection, CoQ10 reduces wrinkles, improves skin firmness, and combats signs of ageing. The best collagen complexes for beauty include this powerful ingredient.

Vitamin C and Hyaluronic Acid

Vitamin C is essential for collagen synthesis, and hyaluronic acid helps maintain skin hydration and joint lubrication. Other proven vitamins for collagen support include vitamins B2, B3, B7 (biotin) and E. Useful minerals for hair, nails and skin include zinc, copper, iodine and selenium.

Lactobacillus Acidophilus for clear skin

This probiotic is proven to help the skin glow in several ways. It kills various bacteria that can infect the skin and cause pimples, skin blemishes and rashes or even make eczema worse. It also shields the skin from sun damage, fending off wrinkle formation.

Avoid

Artificial additives or flavours

Unnecessary ingredients can dilute the product's potency and may cause unwanted side effects. In particular, beware of hidden sugar and artificial flavours in gummies or in powder supplements designed to be added to drinks.

Too many gimmick ingredients

Superfoods may sound nice in an ingredients list, but they're not all clinically tested or proven to have any benefit in supporting human collagen - especially in the tiny quantities that can fit inside a capsule. They're often included at the expense of effective doses of proven ingredients.

Proprietary blends without disclosed amounts

Proprietary blends often hide the true dosage of each ingredient, making it impossible to know if you're getting an effective amount. Be especially wary of supplements that aren't transparent on how much collagen they contain.

Our Expert's Conclusion

This powerhouse formula boasts a strong and effective 1000mg dose of marine collagen that's hydrolysed for maximum absorption. The addition of a potent 2.5 billion CFU dose of the clinically proven skin health probiotic, Lactobacillus acidophilus, sets this product apart, working from within to help keep skin clear of blemishes.

Swallow's Pro Collagen Peptides is also packed with antioxidant CoQ10 and a full dose of hyaluronic acid to keep your skin hydrated and youthful. It goes even further by including a blend of five vitamins (C, B2, B3, D-biotin and E) at strong doses and in their activated, highly bioavailable forms. It also packs in four minerals - zinc, iodine, copper and, unusually, selenium - which work together to give proven support for collagen synthesis and skin, hair, and nail health.

While this product isn't the cheapest and is only available online, we think it's worth every penny. Plus, with third-party lab testing for purity and a 6-month money-back satisfaction guarantee, Swallow demonstrates a commitment to customer satisfaction that's hard to beat.
