Do I need to take both biotin and collagen?

With the popularity of supplements like biotin and collagen, many people wonder if they need to take both or if one is enough. Biotin and collagen serve different purposes in the body, so in many cases, there are benefits to taking both.

What is Biotin?

Biotin, also known as vitamin B7, is a water-soluble B vitamin that helps convert food into energy. Here are some key facts about biotin:

Biotin helps enzymes do their jobs. These enzymes are involved in important processes like making new glucose and fatty acids.
It contributes to skin health by helping with skin cell growth and lipid metabolism.
Biotin helps keep hair and nails strong and healthy.

Recommended daily intake is 30 mcg for adults per day.
Deficiency is rare but can cause hair loss, brittle nails, fatigue, and more.
Good food sources include meat, fish, eggs, nuts, seeds, and certain vegetables.

What are the Benefits of Taking a Biotin Supplement?

Some potential benefits of taking a biotin supplement include:

May promote hair growth and reduce hair loss. A deficiency can lead to hair loss, and getting adequate biotin may help strengthen hair.
May contribute to healthy nails. Brittle nails may be a sign of biotin deficiency.

May improve skin health and reduce acne. Biotin assists in skin cell growth.
May help reduce fatigue. Biotin helps turn nutrients from food into usable energy.
Those with a deficiency may see improved symptoms when supplementing.

However, there is limited research on the benefits for those without a deficiency. But for those struggling with hair, skin, and nail issues, a biotin supplement may help provide a boost.

What is Collagen?

Collagen is the most abundant protein in the human body. It makes up the connective tissues throughout the body and provides structure and elasticity. Here are some key facts about collagen:

There are over 16 types, but 80-90% in the body are types I, II, and III.

It is found in the bones, muscles, skin, blood vessels, digestive system, and more.
It provides tensile strength, structure, and flexibility to the skin, joints, and other connective tissues.
After age 25, collagen production starts declining. As we age, collagen loss leads to sagging skin and joint discomfort.

Good food sources include bone broth, chicken, fish, eggs, berries, citrus fruits, and some vegetables.

What are the Benefits of Taking Collagen Supplements?

Some potential benefits of taking a collagen supplement may include:

Reducing visible signs of skin aging like fine lines, wrinkles, and skin dryness.

Increasing skin elasticity and hydration for a more youthful appearance.
Helping increase muscle mass and strength as we age.
Supporting joint health and flexibility.

Reducing joint pain and discomfort.
Boosting metabolism and helping with weight loss.
Improving hair thickness and reducing hair loss.

Supporting healthy nails.
Helping improve digestive health and healing leaky gut.

Research has shown some promising results related to these benefits, especially for improving skin, joint, and hair health.

Do You Need Both Biotin and Collagen?

Biotin and collagen supplements serve very different purposes, so in many cases, there are benefits to taking both rather than just one or the other. Here are some reasons you may want to take both:

Biotin helps metabolize nutrients and produces energy, while collagen provides the building blocks for strong structural tissues.
Biotin helps specifically with hair, nails, and skin because it assists in cell growth and lipid metabolism. Collagen helps structurally reinforce connective tissues to improve appearance.

Collagen addresses overall skin aging, while biotin tackles acne and other skin issues like eczema specifically.
Biotin may help prevent hair loss and brittle nails, while collagen thickens hair and makes nails strong.
Collagen aids joint health, while biotin reduces fatigue.

They work synergistically to promote strength, flexibility, and youthfulness. Since they work in different ways, combining them can boost effects. Taking biotin may not do much for sagging skin or joint pain, while taking collagen may not affect acne or nails. Getting both covers all the bases.

Are There Any Side Effects or Precautions?

Biotin and collagen supplements are generally safe, especially when taken at recommended dosages. However, there are some things to keep in mind:

High doses of biotin, like 10,000 mcg per day, may interfere with some lab tests like those involving thyroid hormones. Let your doctor know about supplementation if getting lab work done.

Those with poultry or fish allergies may react to collagen supplements sourced from these animals. Look for vegan or bovine sources if allergies are a concern.
High doses of collagen supplements may potentially lead to digestive issues like heartburn. Start with the lowest dose and increase slowly.
Collagen supplements may lower blood sugar levels, so diabetic patients should monitor closely when starting supplementation.

Speak with a doctor before starting if pregnant, breastfeeding, or taking medications.

How Should You Take Biotin and Collagen?

Here are some tips on taking biotin and collagen supplements:

Take biotin doses of 2,500-5,000 mcg per day, which is enough for most people. Those with medical conditions like brittle nails or hair loss may use up to 10,000 mcg with doctor supervision.

Take collagen doses of 2-5 grams per day. Start low and work up to higher doses slowly.
Take biotin with any food or drink. It does not need to be taken on an empty stomach.
Take collagen 30 minutes before eating or at least a couple hours after eating for best absorption.

Biotin is water soluble, so timing is not important. Collagen absorption is better spaced between meals.
Each can be taken once per day. Consistency is what matters most.
Give supplementation at least 2-3 months to see results as it takes time to impact hair, skin, and nails.

Which Types of Collagen Supplements Are Best?

There are a few major types of collagen supplements:

Collagen peptides – Broken down collagen proteins that are easily dissolved and absorbed. Provides overall collagen support.
Marine collagen – Derived from fish. Best for joint health with high collagen types I and III content.

Bovine collagen – Derived from cows. Also has high collagen types I and III content.
Egg shell membrane collagen – Derived from egg shells. May be best for joint inflammation and skin health.

Collagen peptides or marine collagen provide the most versatile options. Look for a quality supplement from a reputable manufacturer for best results. Hydrolyzed collagen increases bioavailability.

Sample Regimen for Combining Biotin and Collagen

Here is an example daily regimen for how to combine taking biotin and collagen supplements:

Take 5,000 mcg biotin with breakfast
Take 2.5 grams marine collagen peptides mid-morning between meals

Take 2.5 grams marine collagen peptides mid-afternoon between meals

This provides a solid daily dose of 5 grams collagen alongside 5,000 mcg biotin. The biotin is taken with food for absorption, while the collagen is taken on an empty stomach.

The Bottom Line

In summary, biotin and collagen are complementary supplements that serve different purposes. Biotin helps metabolize nutrients for cellular energy and growth, while collagen provides the building blocks for strong structural tissues.

Taking both together can provide synergistic effects for boosting hair, skin, nail, and joint health. Most healthy adults can benefit from moderate doses of biotin up to 5,000 mcg per day and collagen up to 5 grams per day.

Speak with your healthcare provider before starting to make sure they are appropriate for you. Be consistent, take as directed, and allow a couple months to see results. Combining biotin and collagen can help you look and feel your best.
