Collagen has taken the beauty industry by storm, captivating celebrities and skincare enthusiasts alike. This essential structural protein, key to skin elasticity and firmness, has become a leading supplement in the battle against ageing.

As we age, natural collagen production declines, leading to thinner, looser skin. Collagen supplements offer an affordable solution for maintaining youthful, radiant skin. Recently, collagen was hailed as 'The Ultimate Anti-Aging Secret' on ITV’s "This Morning."

2. Revive Collagen

by Revive

PROS

• Contains hyaluronic acid
• Aloe vera juice
• Hydrolysed marine collagen

CONS

• Does not contain any other collagen type
• Price

BOTTOM LINE

Revive Collagen - Hydrolysed Marine Collagen Drink is our number two pick. These flavoured collagen packets are formulated from type I hydrolysed marine collagen. Each packet contains 8.5 g of hydrolysed collagen, which can easily be added to any liquid of your choice. This collagen supplement is easy to add to your daily routine as the collagen packets are easy to take with you when you're on the go. However, Revive Collagen does not have a complete amino acid profile and only contains type I collagen.

RATING

B

AT A GLANCE

• BEST FOR: Hair, skin, and nails
• COLLAGEN TYPES: I
• SOURCED FROM: Marine 

5. Grassfed Collagen Peptides

by Ossa

PROS

• Hydrolysed bovine collagen
• 9 g protein/serving
• Amino acids

CONS

• 2-scoop serving size

BOTTOM LINE

Grassfed Collagen Peptides by Ossa is a non-GMO collagen powder sourced from 100% grass-fed bovine collagen. It is a relatively versatile formula that can be added to coffee, blended into smoothies, or used in cooking. It contains a range of amino acids and also includes protein.

While the packaging clearly lists the amino acid profile, the supplement facts don't clarify how many grams of collagen are included per serving. Additionally, the full recommended serving is 2 tablespoons, which may be less convenient for some than a one-scoop-per-day formula.

RATING

C

AT A GLANCE

• BEST FOR: Joints, hair, and skin
• COLLAGEN TYPES: I, III 
• SOURCED FROM: Bovine

by Vital Proteins

PROS

• Gluten and dairy-free
• Certified grass-fed bovine collagen

CONS

• 110 mg sodium

BOTTOM LINE

Collagen Peptides by Vital Proteins is formulated with 20 g of grass-fed and pasture-raised collagen. 

Like Primal Collagen by Primal Harvest, the Vital Proteins formula is easy to use. Although this unflavoured formula is a solid choice for a collagen powder, some people may want to note that it contains 110 mg of sodium. This is especially something to consider for those watching their sodium intake. It also makes the product less versatile as the sodium content may impact the flavor.

3. Collagen Peptides

RATING

C

AT A GLANCE

• BEST FOR: Gut and joints
• COLLAGEN TYPES: Unspecified
• SOURCED FROM: Grass-fed bovine 

4. Absolute Collagen

by Maxine Laceby

PROS

• Contains hydrolysed type I collagen 
• Neutral flavor
• Contains vitamin C

CONS

• Price
• Ease of use

BOTTOM LINE

Maxine Laceby's Absolute Collagen contains 8 g of hydrolysed marine collagen per scoop. Their collagen is sourced from freshwater Basa Fish. It does not contain gluten, soy, or lactose. These individual packets are easy to bring on the go. It dissolves fairly easily into cold drinks, although it takes a bit longer to dissolve than other collagen powders on this list. Some may want to note that compared to some of the other products featured, the price is on the steeper end.

RATING
