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.

Perfect size for me
Color: Light Color Series, Style: Waffle Pattern, Color: Light Color Series, Style: Waffle Pattern
Washed the cloths before use with just detergent. Pretty much stayed it shape and fluffy texture. It lathers well with any soap and drys fast. Love the texture size more than the exfoliating size. Texture side is great for sensitive face cleaning. The exfoliating side did soften after repeated use. I feel it is still little to rough for the face, but great for the body.

Great quality
Color: Light Color Series, Style: Waffle Pattern
These are a bit oversized compared to regular washcloths but that makes it easier when exfoliating your own back. The one side is soft and plush. They are easy to wring out. They wash up nicely. I use a linen bag when washing them but it's not necessary.

These wash up well. Love the exfoliation side for my legs. Helps my husband get grease from work off. Soft, yet sturdy. Highly recommend.
