Esther’s Favourites
A Note From Esther
Over the past five years of living a circadian lifestyle, I’ve invested considerable time and money testing a wide range of products. Some have been excellent. Many have been disappointing.
Before you buy anything, remember that the most powerful circadian tools are completely free: watching the sunrise, spending time outdoors in natural daylight, enjoying the sunset, and grounding barefoot on the earth whenever possible. These daily habits are the foundation of a healthy circadian lifestyle.
The products featured here are ones I personally use, have used, or confidently recommend based on my research and experience. Think of them as tools that complement those natural practices not replace them.
Some links are affiliate links, which means I may earn a commission if you make a purchase, at no additional cost to you.
If you have questions about any of these products or my experience with them, feel free to reach out. I’ll always give you my honest feedback.

Best starting point for anyone new to a circadian lifestyle. Designed for evening use to support relaxation and better sleep. Available in multiple styles.

Designed for children with both daytime and evening options to support healthy light exposure, mood, focus, and improved sleep.

Red Light Rising
The first pair of blue blockers and the first red light device I ever purchased were from Red Light Rising in 2021 while I was living in Europe, and I still have and use both of them today.
Red Light Rising is the UK’s original red light therapy brand, serving customers throughout the UK, Europe, and worldwide. Their premium-quality products are backed by a 365-day money-back guarantee and excellent customer support.
1. My Top Recommendation: NYX Blue Blocking Glasses
Lab-tested DayPro and NightPro lenses for daytime screen comfort and circadian-friendly evenings. Now available as a convenient two-pack that includes both daytime and nighttime lenses.
Still my favorite pair of blue blockers.
Why I Recommend Them
I’ve owned my NYX night blue blockers for over five years, and they remain my go-to evening glasses. One of the things I’ve consistently noticed is that when I put them on after sunset, I often become sleepy within an hour. Because they block both blue and green light, they help signal to my body that the day is winding down and it’s time to prepare for sleep.
What I Like Most
They’ve stood the test of time. Five years later, they’re still my favorite blue blockers.
2. Target Light
A dual-wavelength red and near-infrared light therapy device designed to support skin, eyes, joints, muscles, and deeper tissues.
Why I Recommend Them
I originally purchased the Target Handheld to help support the healing of a foot injury I sustained while living a travel-focused lifestyle. I wanted something effective, portable, and easy to take with me wherever I went.
I’ve now owned it for over five years and have been consistently impressed by its quality and reliability.
And yes—it helped my foot.
What I appreciate most is its versatility. In addition to using it on my foot, I’ve used it for eye strain, thyroid support, body aches and pains, and even as a relaxing red ambient light in the evening. It’s compact enough to travel with in both carry on and checked luggage, which made it easy to keep using while moving between countries.
What I Like Most
Red Light Rising continues to improve its products. Their latest Target Handheld models, the 2.0 and 3.0, include upgrades such as flicker-free technology, making an already excellent device even better.

💰 Budget-Friendly Blue Blocking Options
Not everyone is ready to invest in premium circadian tools right away. These are two affordable options I’ve personally tested and feel comfortable recommending as a starting point.
Spectra479 Amber Blue Light Blocking Glasses (Sleep)
What It Is
Ultra-effective nighttime blue blockers designed to filter the most disruptive wavelengths of artificial light after sunset.
Why I Recommend Them
A solid pair of blue blockers at an entry level price point. The frames are durable, the lenses are effective, and they’re a great option for beginners, frequent travelers, or anyone looking to improve their sleep without making a large investment. I’ve used these while traveling and appreciate not having to worry about damaging a much more expensive pair.
What I Like Most
I purchased these glasses for two reasons. First, my original budget blue blockers were a huge disappointment, and someone I trust highly recommended these. Thankfully, they lived up to the recommendation. Second, I specifically wanted a wraparound style to reduce blue light entering from the sides of my eyes. They check both boxes and have become one of my favorite budget-friendly options.

Spectra479 Clip-On Blue Light Blocking Eyewear
What It Is
Convenient clip-on blue light blocking lenses designed to fit over your existing prescription glasses.
Why I Recommend Them
If you wear prescription glasses, these offer a simple and affordable solution without needing to purchase a separate pair of blue blockers. The yellow lenses help reduce eye strain and visual fatigue during computer work and screen time.
What I Like Most
The convenience. The clip opens easily, attaches securely, and allows me to use them with my prescription glasses. They’re practical, effective, and very reasonably priced.
Remove Blue Light & Flicker From Your Screens
Your computer, laptop and phone are some of the biggest sources of artificial light you’ll encounter each day. If you’re working to support your circadian rhythm, reducing blue light and screen flicker is one of the smartest upgrades you can make.
Tap Zap (PC & Mac | iPhone | Android coming soon)
What It Is
Tap Zap is an easy to use app that reduces blue light and eliminates screen flicker on supported devices. Unlike many screen filters that simply tint your display, TapZap works at the system level to reduce the blue light reaching your eyes while preventing flicker that can contribute to eye strain and visual fatigue.
With a simple slider, you can instantly adjust your screen for daytime, evening, or nighttime use. It’s a one time purchase, works on up to three computers, and all future updates are included at no additional cost.
Why I Recommend It
I’ve tried several screen filtering programs over the years, and none of them completely satisfied me. Some were overly complicated, while others created issues with my computer.
TapZap was different.
It’s incredibly easy to install and use. Within minutes I had an icon on my desktop and now I simply move a slider to adjust my screen depending on the time of day. If I want extra protection, I can also enable Flicker Safe Mode with a single click.
Even though I still recommend wearing quality blue blocking glasses, TapZap provides another layer of protection especially during long hours on the computer.
What I Like Most
The difference was immediate.
Within seconds my eyes felt more relaxed and comfortable. If I happen to forget my blue blockers while working, I know my screen is already much more circadian friendly.
I also appreciate that Tap Zap was created by my friend Rusty, someone who is deeply committed to helping people reduce blue light and unnecessary EMF exposure. It’s refreshing to use software designed by someone who truly understands the needs of the circadian community.
Simple. Effective. No monthly subscription. Just install it, choose your settings, and enjoy a more comfortable viewing experience.
Red Light Therapy Tools Worth Exploring
Bon Charge
Science-backed wellness tools designed to support sleep, recovery, and overall well-being through optimized light exposure.
Bon Charge Bullet Red Light Therapy Device
What It Is
A lightweight, portable red light therapy device designed for targeted use anywhere on the body. Small enough to fit in a pocket, handbag, or gym bag, making it easy to take red light therapy with you wherever you go.
Why I Recommend It
The Bullet is incredibly versatile. It can be used on the face, sore muscles, or areas of injury. I also like that it can be used in a family setting. Children can comfortably use it for bumps, bruises, or minor scrapes. It’s a simple way to support recovery, energy, mood, and overall well-being.
What I Like Most
Its portability. I can easily take it to the gym, travel with it, or use it discreetly anywhere I want for quick, targeted red light support.
Bon Charge Full Spectrum Lamp
What It Is
A flicker-free, low-EMF full spectrum lamp designed to mimic natural phases of sunlight. It helps create a circadian-friendly indoor lighting environment for home or office use.
Why I Recommend Them
It allows you to optimize your indoor light environment throughout the day and evening. The touch controls make it easy to adjust the brightness and colour temperature depending on your mood, task, or time of day.
What I Like Most
The flexibility. I love being able to shift the lighting depending on what I’m doing whether it’s working, winding down in the evening, or reading in bed without disrupting my sleep rhythm.
Circadian Friendly Lighting
670nm Red Night Lights with Retractable Plug [2 – 8 Pack]
What It Is
A plug-in red night light designed to create a soft, red glow that supports a calm, sleep-friendly environment. Unlike standard night lights, it contains no sleep-disrupting blue light, making it ideal for nighttime navigation without interfering with your circadian rhythm.
Why I Recommend It
Waking up at night and flipping on bright lights or trying to move around in the dark isn’t ideal for your nervous system or your sleep. These red night lights solve that problem in a simple, practical way.
I purchased the 6-pack and have them placed throughout my home, and I always travel with at least one. They’ve become one of those small but essential upgrades that make nighttime living much easier and more supportive.
What I Like Most
They provide just enough light to safely navigate without fully waking the body up or lighting the entire room. It’s a soft, grounding glow rather than harsh illumination.
I also appreciate the smart auto-dimming feature. The built-in light sensor automatically turns them on at dusk and off at dawn, and adjusts brightness based on surrounding light conditions so you never have to think about them.

Supplements
PureBulk
What It Is
PureBulk is a supplement company founded in 2008 that specializes in pure, single ingredient vitamins, minerals, and nutritional compounds without unnecessary fillers, binders, or additives.
Why I Recommend It
I like PureBulk because of their focus on simplicity and purity. Instead of heavily processed blends, they offer straightforward ingredients like amino acids, herbal extracts, vitamins, and minerals.
It also gives you the ability to tailor your own dosing, which is especially useful if you prefer a more intentional and minimalist supplement routine.
What I Like Most
My go to purchase is their Magnesium Bis-Glycinate, it’s become a staple in my daily routine.
I also appreciate the consistency, purity, and wide range of single ingredient options. It’s a simple, no-nonsense way to support foundational health without unnecessary extras.

Nourishing Skin & Personal Care
Top Shelf Tallow
What It Is
Premium grass-fed beef and lamb tallow skincare handcrafted in Canada.
Why I Recommend It
Not all tallow skincare products are created equal.
The quality of the raw suet, rendering process, filtration methods, and handling all influence the final product. Top Shelf Tallow is produced by a professional meat specialist with more than 25 years of experience working directly with premium beef fat, bringing a level of technical knowledge and craftsmanship that sets their products apart.
I appreciate that they prioritize quality ingredients and traditional methods rather than taking industrial shortcuts.
What I Like Most
I’ve personally used the Supreme Balm, Feet Cure, and Propolis Serum.
The Propolis Serum was a game changer for my very dry skin during the winter months. It helped restore moisture when my skin needed it most, and I now use it two to three times per week as part of my regular routine.
The Feet Cure turned out to be a pleasant surprise. While it was designed for feet, I discovered it works beautifully on dry hands as well. I keep a tin in my purse for quick hand rescue whenever I need it.
The Supreme Balm has become my go-to moisturizer after showering. It’s simple, nourishing, and leaves my skin feeling soft without a long list of ingredients.

Circadian Friendly Lifestyle Products
Luxury Turkish Cotton Hooded Bath Robe
One of my favourite comfort purchases in recent years.
What It Is
A luxurious 100% Turkish cotton bathrobe designed for comfort, warmth, and everyday use. Made from premium long-staple Turkish cotton, it offers exceptional softness, durability, and a spa-like feel without the synthetic fabrics commonly found in plush robes.
Why I Recommend It
When living a circadian and natural lifestyle, the fabrics we wear matter. I personally prefer natural fibers whenever possible, and this robe is made from 100% Turkish cotton, soft, breathable, absorbent, and comfortable against the skin.
Unlike many plush robes made from polyester, this robe is crafted from a natural fiber that feels wonderful to wear. It’s quick-drying, available in several colours and styles, and has the quality and comfort of a luxury hotel robe without feeling bulky or heavy.
What I Like Most
I absolutely love this robe!
I purchased the hooded version in baby pink when I arrived in Alberta during a particularly cold season, and it quickly became part of my daily routine. I wore it around the house, after bathing, and whenever I wanted to feel warm and comfortable.
It’s soft, luxurious, and beautifully made. I especially appreciate the deep pockets, the hood, and the generous overlap in the front that helps keep you warm. I typically wear a size Large and purchased the M/L, which fit perfectly—even after washing.
Available in both women’s and men’s styles.
