Biotin or Collagen: Which Should I Take?

There are lots of benefits to both biotin and collagen, but I want to help you take the right supplements for your needs. So let’s have a look at which is better: biotin or collagen.

Biotin Or Collagen

My clients are always asking me which supplements are best for their hair, skin, nails, and teeth while they’re on their weight loss journey. We want our bodies to be healthy and strong (and gorgeous), so we’ve got to eat healthy and take the right supplements!

Biotin and collagen are the two supplements that most people choose between when trying to strengthen their hair, skin, and nails. People always ask the difference between the two, so let’s dive in with the ins and outs of biotin and collagen!



Benefits of Biotin

Biotin is a B vitamin that has a few different benefits on our health:

  • Hair growth – a deficiency of biotin in your body can cause hair loss. 
  • Skin health – if you don’t have the right amount of biotin in your diet, toxins start to pop out on your skin (usually in the form of rashes or acne).
  • Regulating blood sugar – biotin can help you regulate your blood sugar and cholesterol levels

The beautiful thing about biotin is that you can find biotin in foods you are already eating. Biotin can be found in:

  • Egg yolk
  • Nuts and seeds
  • Salmon
  • Dairy
  • Avocado
  • Sweet potato
  • Cauliflower


Benefits of Collagen

Collagen is actually a protein–it makes up a portion of the proteins in your body. Our skin, for example, is about 75% collagen. Ithelps bind your skin together, making it more elastic and tight. But as we grow older, we have less collagen in our body so supplements are popular. 

Collagen can help you with your:

  • Skin
  • Hair
  • Nails
  • Joints
  • Teeth
  • Gums
  • Cellulite
  • Digestion
  • Metabolism
  • Hormones
  • Sleep

Hydrolyzed collagen, or the collagen that is easiest for your body to absorb, isn’t found in food that you can eat–which means you’ll need a different way to best supplement your collagen production.

If it’s between using a biotin supplement and a collagen supplement, I totally suggest trying out collagen. Biotin can be found in foods you can add to your diet, while hydrolyzed collagen cannot be consumed in a food!

I recommend collagen to all of my clients who are trying to lose weight. And it’s best to find a pill made up of hydrolyzed collagen, which means the collagen is broken down into the smallest pieces possible so that your body can absorb the collagen more efficiently.

Collagen is especially important for your skin while losing weight. If you lose a large amount of weight in a short amount of time, your skin may not have the ability to bounce back, and you’ll end up with a lot of extra skin hanging around.

Collagen helps your skin be more elastic and tight, which helps people look great while losing weight. If you supplement your diet with collagen, your skin will be more able to bounce back after your awesome weight loss journey!


Which Should I Take: Biotin Or Collagen?

Whether you’re looking to strengthen your hair, skin, or nails, collagen is the way to go. If you’re deciding between biotin and collagen, remember that you can get the full benefits of biotin through foods, but you can only get the full benefits of hydrolyzed collagen in a collagen supplement.
