Pure Lab Vitamins - Bioactive B Complex - 120 Slow Release Capsules - NPN: 80075169 

Research-supported ratios of biologically active B vitamins with the sustained benefits of a slow-release formulation

As our lives become more stressful and urgent, our water-soluble B vitamins are quickly exhausted. We need them for energy production, red blood cell and neurotransmitter production, and a myriad of other processes in the body that greatly influence how we feel.

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.

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.

From a Long Time Hard Sole Dress Shoe Wearer, These are a Must Have!
Size: 12, Color: Blue
I have been wearing hard sole dress shoes for decades and with the full COVID shift to dressing super casual in a professional work environment, I was in the market for some more casual let dressy shoes that were a heck of a lot more comfortable and flexible than my hard soles so I thought I would give this brand and style a try. Oh man, I'm in love. These give you that dressier look yet you can totally dress them down with jeans or cordouroys, so versatile. As I did with my hard soles, I inserted one of my Nike Air in soles and man, these are so comfortable I bought navy and brown! I usually wear these with thin dress socks and they go perfectly with any type of suit set, a no brainer purchase here. I'm a 12 and bought a 12, perfect fit, not to skinny, not to wide, just right. Bottom sole grip is impressive, never felt unstable, solid rubber sole here. I decided to lace them up so there are not tying and the tongue does slip down sometimes so with this feature, best to use a metal shoe horn, then it's super easy to slide them on, they seem to take a beating and remain clean too, I've definitely scuffed them up against many things and still no damage, it's crazy, must have a great finish. NOTE TO Note to MANUFACTURER/SELLER - You need to make a version in GRAY in this specific style and I will buy them instantly, and I assure you they will be incredibly popular! Really not sure why there isn't more colors in these like gray, shades of gray, maybe red, lighter blue and maybe some with different tones in standard colors. Casual dress shoe wearers are looking for new and exciting bold colors so this is the perfect shoe type to deliver on that.
