Feed Your Glow: The Functional Beauty Blueprint for Skin, Hair, and Nails

True beauty radiates from within. When your gut is nourished, your skin clears, your hair shines, and your overall vitality soars. That’s precisely why the same foods that fuel healing in my 21-Day Gut Healing Program double as nature’s most potent beauty elixirs.

Even beyond gut healing, there are many foods and nutrients you can incorporate into your daily diet or supplement routine.

In this blog, we’ll explore how hydration, foundational nutrients, and intelligent skincare choices combine to support glowing skin, strong hair, and resilient nails—all while helping you look and feel your best.

Hydration is Your Foundational Beauty Ritual

Before any trendy creams or serums come into play, drink more water! 

Hydration is the invisible beauty habit everyone underestimates. Skin is 64% water—stay hydrated, and it stays plump, supple, and youthful. Even slight dehydration shows up as dullness or fine lines. 

Not only is this the most foundational element of health, it’s also the subtle key to glowing, vibrant, and toned skin. 

These strategies will help keep you glowing and hydrated throughout the day:

• Water — aim for 1/3 of your body weight (in ounces) per day.

• Pro tip — Get a large metal water bottle *not plastic* about 32oz or more, and determine how many times you need to fill it up and drink it daily to make it easier to track intake.

• Hydrating foods — cucumber, watermelon, tomatoes, bell peppers, lettuce, and bone broth.

• Add Electrolytes to your water for cellular hydration. This is my favorite brand. 

Hydrated skin is radiant skin.

Glow-Building Nutrients + Their Beauty Roles

Certain nutrients are essential in beauty nutrition. Nutrients are what build your tissues. 

Your number one key nutrient, as far as calorie intake goes, is protein. If you aren’t eating enough protein, you’re body won’t have enough building blocks left to nourish your skin and connective tissues optimally.

Several micronutrients are key for “building up” the building blocks that protein provides:

• Vitamin C
  Vital for collagen synthesis and skin strength. Collagen is the primary protein responsible for maintaining skin firmness and resilience. If collagen is the “bricks”, then vitamin C is the mortar that holds them together. Collagen is shaped like a thick rope. As we age, you can imagine the fibers in the rope starting to fray. Vitamin C helps to wind the fibers together. 

• Retinol (Pre-formed Vitamin A)
  Essential for skin cell development, clarity, and brightness. While some foods offer provitamin A (beta-carotene), conversion to active retinol is inefficient—especially in women. Human studies have shown highly variable absorption and conversion of beta-carotene, with ratios ranging from 8% to 24% (1). Dietary guidelines now estimate ~12 μg of beta-carotene equals 1 μg of retinol (2)—making pre-formed retinol sources critical.

• Omega-3 Fatty Acids
  Anti-inflammatory fats that support skin hydration, elasticity, and shine. Think of omega-3s as the “moisturizer from the inside out.” These healthy fats help keep your skin barrier strong, so hydration stays locked in instead of evaporating. Without enough omega-3s, your skin is more likely to feel dry, flaky, or inflamed. EPA and DHA also calm irritation by dialing down the body’s “inflammatory thermostat.” That’s why omega-3s can help with acne, eczema, and even sun sensitivity

• Zinc 
  Key for skin repair and UV resistance; support hair strength and shine. Zinc is like your skin’s “repairman.” Every time you get a scratch, breakout, or flare of irritation, zinc rushes in to rebuild and restore the damaged tissue. It also keeps oil production balanced, which is key to preventing clogged pores. Without enough, wounds can take longer to heal and skin may be more prone to breakouts.

• Selenium
  

  Acts as your skin’s “bodyguard.” Selenium protects against free radical damage from UV rays and environmental toxins, helping to slow signs of aging. It also works closely with vitamin E to strengthen the skin’s defense system. Brazil nuts are the richest source—just 1–2 per day can cover your needs..

• Vitamin E
  Think of vitamin E as your skin’s natural “barrier oil.” It helps your cells hold onto moisture while protecting them from environmental stress. Because it’s fat-soluble, it works best when eaten with healthy fats like avocado or olive oil. Without enough, skin can become dry and more prone to irritation.

• Polyphenols and Antioxidants
  These are your skin’s “cleanup crew.” Every day, free radicals from stress, toxins, and UV rays cause wear and tear on your cells. Antioxidants neutralize that damage, keeping skin smooth, youthful, and glowing. You’ll find them in colorful foods like berries, green tea, and dark chocolate.

Top Glow-Promoting Foods

Here’s how these nutrients translate into real meals:

Bonus: Rich carotenoid intake has been known to reduce keratosis pilaris in clients, and supports vision—two added beauty perks.

Skincare That Works: Toxin-Free & Effective

What you put on your skin matters just as much as what you eat. Here are some of the best clean, science-backed (not overhyped from a social media trend) options to try:

• GHK-Cu (Copper Tripeptide-1)
  A potent peptide shown clinically to reduce wrinkle volume by ~56% and depth by ~33% over 8 weeks (3). It boosts collagen, elastin, and skin thickness. A synergy exists when it’s combined with hyaluronic acid—enhancing collagen I, IV, and VII production (4).

• Sweet Almond Oil + Mica
  For an all-day dewy glow + shimmer, this is a radiant duo—nourishing the skin with vitamin E and delivering a natural glow without greasiness or synthetic chemicals. Almond oil offers a great shimmer. Add some ethically sourced mica powder, and you have yourself a super easy DIY body shimmer oil.

• Avoid Parabens and Phthalates
  Common in many mainstream personal care products, these chemicals are linked to endocrine disruption and skin sensitivities. Go for clean formulations.

My Favorite Functional Beauty Products

I use each of these products every day as part of my internal beauty routine. 

I can tell you from personal experience that if you have hormone-related hair loss, Copper IQ serum will not only help reduce the loss but also promote hair growth better than any hair-skin-and-nail vitamin. And Cod liver oil is the best go-to for keratosis pilaris. It worked for me and my clients.

Why These Strategies Work So Well Together

• Internal nourishment from food and supplements supplies your skin with building blocks—vitamins, antioxidants, proteins—to repair and glow.

• Targeted topical ingredients like copper peptides and hyaluronic acid enhance that support at the surface—stimulating collagen and promoting elasticity.

• Hydration (internal + topical) ensures products and nutrients are fully functional, plumping skin and supporting vibrant health.
