Add to that an active lifestyle, a limited diet, pregnancy, a diagnosis of diabetes, migraines, depression, neuropathy or cardiovascular disease and the negative effects of insufficient B vitamins are compounded.
Making things more challenging is that diet does not always provide the optimal daily allowances that are needed in these situations. Plus, some individuals may lack the ability to convert and absorb specific B vitamins.

Pure Lab’s Slow Release BioActive B-Complex is comprised of all B vitamins, including the biologically active forms of thiamine (benfotiamine), niacin (inositol hexanicotinate), riboflavin (riboflavin-5-phosphate, folate (calcium-L-5- MTHF), B6 (pyridoxal-5-phosphate) and B12 (methylcobalamin). Like a fully-charged battery instead of a partially drained one, the vitamins in our formulation are ready to perform metabolic work as soon as they get absorbed. This balanced ratio of B vitamins in their bioavailable form provides the support necessary to improve resilience against stress.
We consider our Slow Release BioActive B-Complex a foundation product that can benefit anyone looking for improved mental and physical energy.
Because B vitamins are water-soluble, getting used up or excreted quickly, Pure Lab’s Slow Release BioActive B-Complex product was formulated to support the maintenance of blood levels over a longer period of time—about 4 to 5 hours per capsule. That’s about twice as long as standard B complex formulations. This minimizes most individuals’ daily dose to just 1 or 2 capsules.
We recommend taking 1 capsule with food at the start of your day, and another 1 at lunch time. Doing this, what you’re going to notice is a bright yellow tint to your urine that lasts throughout the day. That’s visible proof of the slow-release effect.

Why does my urine turn bright yellow when I take Pure Lab’s Slow Release BioActive B Complex?
Answer: It is normal for urine to turn bright yellow while taking supplements that contain Vitamin B2 (riboflavin) or its biologically active form, riboflavin-5-phosphate. This is the colour of the vitamin in concentrated, powdered form. Since Vitamin B2 is water-soluble, any unused portion cannot be stored by the body so it is excreted into the urine.
How long do the effects of Pure Lab’s Slow Release BioActive B Complex last?
Answer: On average, an individual can expect to maintain serum (blood) B vitamin levels from 1 dose of our Slow Release BioActive B complex over a period of 4 to 5 hours. When 2 capsules are taken together, you will see bright yellow urine for up to 10 hours after ingestion. However, individual experiences vary based on diet and metabolic differences.
Which ingredient in Pure Lab’s Slow Release BioActive B Complex is responsible for the slow-release effect and how does it work?
Answer: The ingredient in Pure Lab’s Slow Release BioActive B Complex responsible for the slow-release effect is hypromellose SR. This is a fiber derived from the pulp of the poplar or birch tree. The hypromellose SR is mixed with the ingredients within the capsule so that it forms a gel upon contact with digestive fluids. This allows for a slower release of the B vitamins, and therefore, a more gradual entry into the bloodstream for sustained benefits.
Are the B vitamins in Pure Lab’s Slow Release BioActive B Complex methylated?
Answer: All of the B vitamins in Pure Lab’s Slow Release BioActive B Complex are in their activated form. They are either methylated (for ex., B9 and B12) or phosphorylated (for ex., B2 and B6). In both cases, they are biologically active.
How are the B vitamins in Pure Lab’s Slow Release BioActive B Complex different from taking a regular B complex?
Answer: The B vitamins found in food and most supplements require conversion into biologically active forms before we can fully benefit from them. Pure Lab’s Slow Release BioActive B Complex contains biologically active B vitamins, ready to perform metabolic work. This is akin to using a fully charged battery, instead of a partially drained one.
Does Pure Lab’s Slow Release BioActive B Complex need to be taken with food?
Answer: To reduce chance of stomach discomfort, Pure Lab’s Slow Release BioActive B Complex can be taken with food—preferably no later than the 2nd meal of the day.
Does Pure Lab’s Slow Release BioActive B Complex have any side effects?
Answer: Like with all Vitamin B2 - containing supplements, Pure Lab’s Slow Release Bioactive B Complex turns the urine a bright yellow colour. This is normal and harmless. Some individuals may experience difficulty falling asleep when a B Complex supplement is taken with their evening meal. For this reason, it is advised that Pure Lab’s Slow Release Bioactive B Complex be taken no later than with your mid-day meal.
What use is Pure Lab’s Slow Release BioActive B Complex approved for?
Answer: In Canada, the registered health claim for Pure Lab’s Slow Release BioActive B Complex is: “Balanced B-Vitamins in their active form help metabolize carbohydrates, proteins and fats for energy, tissue support and red blood cell formation.”
