Zilis Review August 2022

Zili s’ Ultra line prides itself on using UltraCell technology , utilizing most of the active compounds found in hemp, including other cannabinoids , terpenes , fatty acids , and flavonoids .

According to Zilis, UltraCell technology uses liposomes and micelles to increase the bioavailability of CBD.

Liposomes are particles that house and deliver substances throughout the body (1) . Meanwhile, micelles help the body absorb water-insoluble compounds (2) ,

Zilis CBD products are said to be full-spectrum, containing both cannabidiol (CBD) and tetrahydrocannabinol ( THC ), the primary psychoactive compound s found in cannabis . These phytocannabinoids are seen to benefit multiple neurological functions (3) .

When working together, these cannabinoids and other hemp components produce the entourage effect , the synergy between all active compounds that magnifies the overall health benefits of CBD (4) .

Zilis is labeled a multi-level marketing company, which has garnered negative reviews from the Better Business Bureau (BBB). Despite this feedback , the brand continues to work on improving its product line with the help of medical professionals.

Its products have garnered positive reviews from buyers. Comments on third-party seller websites cite UltraCell CBD items as quality products that helped them with pain relief and anxiety. However, the legitimacy of these reviews is questionable.

The brand claims its inventory is made of all- natural products that are certified by the US Hemp Authority.

Review of Zilis Products

Zilis UltraCell Full-Spectrum Hemp CBD Oil

Zilis UltraCell Full-Spectrum Hemp CBD oils are water-soluble mixtures said to have a bioavailability or absorption rate of 94% due to UltraCell technology .

Research has linked CBD to pain relief (5) and anxiety management (6) .

Both lemon and berry-flavored CBD oils are flavored with natural ingredients from plant extracts and contain medium-chain triglyceride ( MCT ) oil from coconut as the carrier oil.

Studies show that MCT oil may aid in weight loss and weight maintenance (7) and offer relief from gastrointestinal issues (8) . MCT oil is also observed to enhance energy expenditure (9) .

The raw variant uses sunflower lecithin, which is derived from sunflower seed oil. A 2012 study noted that sunflower and other dietary lecithins help decrease cholesterol levels and improve liver health and cognitive functions (10) .

The product list also includes xanthan gum and acacia gum. These food stabilizers are said to aid gut health as prebiotics (11) .

All Zilis UltraCell Full-Spectrum Hemp CBD Oils are sweetened with stevia and use potassium sorbate as a preservative, extending their shelf life to 18 to 24 months from the manufacturing date indicated on the packaging.

Lab reports state that these CBD oils have trace amounts of yeast and mold.

This product comes in 15ml and 30ml dropper bottles, with 15 and 30 servings per bottle, respectively.

Zilis recommends a dosage of one dropper (1ml) per day or as directed by a healthcare professional. This oil may be taken sublingually or mixed with food and beverages.

Zilis UltraCell Pet

Zilis UltraCell Pet is a full-spectrum oil formulated specifically for cats and dogs. It contains fish oil (salmon) for flavoring and sunflower lecithin as its carrier oil.

According to the Cummings Veterinary Medical Center at Tufts University, the omega-3 found in fish oil may help reduce risks for debilitating symptoms associated with joint, heart, and kidney disease in cats and dogs (12) .

Fish oil may also alleviate itchy, flaky skin and promote a healthier, silkier coat for your pets (13) .

Its formulation is free from the artificial sweetener xylitol, which, according to the US Food and Drug Administration ( FDA ), is toxic to dogs (14) .

Zilis recommends a dosage of 0.02mg per 1kg of body weight, to be taken orally twice daily.

Zilis UltraCell Full-Spectrum Hemp CBD Topical

Zilis UltraCell Full-Spectrum Hemp CBD Topical is a CBD-infused cream containing aloe leaf and essential oils. It is designed for pain relief while leaving your skin moisturized.

Research has identified cannabinoids to hold analgesic or pain-relieving properties and reduce inflammation to aid with sore joints (15) .

Clinical trials on aloe leaf extracts indicated beneficial effects on skin issues, particularly relief from itching and burning sensations associated with psoriasis , dermatitis, and other skin conditions. It is widely used in the cosmetic industry as a base for moisturizing creams and soaps (16) .

The main essential oils included are black pepper oil, citronella oil, ginger root oil, and helichrysum flower oil. Studies also found these oils to have anti-inflammatory and antioxidant properties (17-19) , while citronella oil is commonly used as a mosquito repellent (20) .

Zilis UltraCell Full-Spectrum Hemp CBD Topical is available in two sizes: a 7ml tub and a 2oz tub.

Zilis ’ claims of UltraCell technology ’s effectiveness on increasing CBD oil bioavailability may set Zilis UltraCell Full-Spectrum Hemp CBD Oil apart from other products available on the market.

The brand’s reputation as a multi-level marketing company and its lack of accessible COAs and other information has not dissuaded people from trying its products.

Product prices are hefty, especially when taking into account the product’s low CBD concentration as per outdated COAs. Despite these factors , many customers found the products effective and worth repurchasing. However, a number of CBD users questioned the validity of these reviews.

How to take CBD:

Take .5-1 mL daily. You can split up the doses by taking a half dropper in the morning and half dropper at night. It’s best to start off at a lower dosage and work your way up to the perfect dose.

Everyone is different. Your first month should be spent experimenting to find the ideal amount of CBD for your body.

  • How To Take Directly: Put the drops under your tongue and let them sit there for 30-60 seconds to maximize your absorption.
  • Other Ideas: You can put CBD in your coffee, tea or healthy shakes. Still: CBD is best absorbed under your tongue, and this tasty flavor makes that easy.

Ingredients: Purified Water, Glycerin, MCT (from coconut), Natural Flavors (from plant extract), Prebiotic Polysaccharides (from Xanthan and Acacia Gum), Natural Lipids (from non-GMO sunflower), Stevia (from leaf), Potassium Sorbate.

Everyone is different and there are countless variables such as weight, diet, metabolism, genetics, and environment that make a universally prescribed dose difficult. With these facts in mind, most people who are new to cannabidiol begin their journey with a minimal dose an then gradually increase until they achieve the desired results.
