Description
L-Theanine provides an impressive 250 mg of pure L-theanine along with 20 mg of magnesium bisglycinate to promote a state of relaxation and reduced anxiety without sedation, so that you can stay focused and productive.
L-Theanine is a non-protein amino acid that occurs naturally in the green tea plant. Studies show that L-theanine induces alpha brainwave activity, which correlates with a perceived state of relaxation. A small Japanese study of university students demonstrated that oral administration of 200 mg of L-theanine led to increased alpha brainwaves and a subjective sense of relaxation. Theanine administration caused a dose-dependent, relaxed yet alert state of mind without sedation, beginning approximately 40 minutes after oral dosing.
Magnesium is a mineral that is especially important for muscle function. It acts with calcium to help regulate the body’s nerve and muscle tone, and helps to relax muscles and prevent spasms. Inadequate magnesium appears to reduce serotonin levels, which is why symptoms of magnesium deficiency can include anxiety and depression. A 2008 study found that magnesium was as effective as tricyclic antidepressants in treating depression among people with diabetes.
Frequently Asked Questions
What is CanPrev and are its supplements Health Canada approved?
CanPrev is a Canadian natural health supplement brand founded in 2005 by Tanya Salituro -- the name stands for Canadian + Preventive. All products are Health Canada licensed and manufactured at site-licensed, government-approved Canadian facilities, with each batch independently laboratory tested for potency, purity, and safety before release. The brand offers 445+ formulations across therapeutic categories including magnesium, amino acids, vitamin D, hormonal support, and women's health, distributed in 3,400+ Canadian retail locations and through naturopathic practitioners. In February 2025, CanPrev was acquired by Apotex, further expanding its distribution infrastructure.
How is CanPrev different from other Canadian supplement brands?
CanPrev's distinguishing feature is practitioner co-formulation: roughly 25% of the company team are licensed health practitioners -- naturopathic doctors, nutritionists, and herbalists -- meaning products are formulated with clinical input from the start, not adapted for retail after development. The brand consistently selects more bioavailable nutrient forms: methylcobalamin over cyanocobalamin for B12, magnesium bisglycinate over magnesium oxide, active folate (5-MTHF) over folic acid -- at therapeutic doses, and formulates without fillers or binders. This distinguishes CanPrev from mainstream supplement brands that use lower-cost, less-absorbed nutrient forms to reduce per-unit manufacturing costs.
