Why Should I Take Infini-B?

When it comes to brain function and energy production, the B vitamins are incredibly important! Without them, a lot of neurotransmitters couldn’t be synthesized, myelin sheaths would degrade and food wouldn’t turn into usable energy as readily. B-vitamins however are all water soluble, and because of this, they are not stored in the body like other fat soluble vitamins are. This means that B-vitamins need to be constantly replenished. This happens via our diet, but deficiencies can occur over time. This can have negative impacts on cognitive function, mood, focus, skin health and even metabolic function. Thus, it is no surprise that B-vitamins are incredibly popular as additions to nootropic stacks!

So, what makes Infini-B unique? In a sea of B-vitamins, we questioned ourselves if we even had anything to add to the B-complex space. However, we were taking B-vitamin supplements ourselves, and were always selecting one with the least amount of compromises. We instead wanted to create a B-complex without any compromises, which we achieved with Infini-B! First of all, most B-complex supplements on the market use forms of B-vitamins that do not absorb well or simply aren’t very active. Sometimes well absorbing or active B-vitamin forms are sprinkled into a complex composed of other cheaper less effective B-vitamins. This was the first compromise we wanted to circumvent, and thus, we included only highly absorbable and active forms of B-vitamins in Infini-B! Secondly, B-vitamins are often either dosed way too low or way too high. We sought to find the perfect dosing level of these B-vitamins, verifying good effects in multiple rounds of beta-testing.* The end result, in our opinion, is one of the best B-vitamin complexes ever created!*

What is Infini-B?

Infini-B is an intelligently designed B-complex, utilizing some of the best B-vitamin forms around, and dosed at the proper levels. Below is a list of all eight B-vitamins that are in Infini-B with a brief description of the form they are in and the general functions they have in our bodies and brains.

Thiamin (Vitamin B1): Benfotiamine + Thiamine HCL

Thiamin is crucial for energy processing and neurological function. It plays a major role in converting glucose to energy, and is required as a cofactor for two critical enzymes involved in cellular respiration, pyruvate dehydrogenase and alpha-ketoglutarate dehydrogenase. Thiamin also plays a role in neurotransmitter synthesis such as acetylcholine, myelin production, and maintaining glutamate, aspartate and GABA levels. The nootropic form of thiamin, benfotiamine, is included in Infini-B for its ability to easily cross the blood-brain barrier, while thiamin HCL is included for general maintenance of thiamin levels.*

Riboflavin (Vitamin B2): Riboflavin 5'-Phosphate Sodium

Similar to thiamin, riboflavin is essential for energy production via the metabolism of macronutrients. Riboflavin achieves this by converting to flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN) which act as electron carriers in enzymatic reactions, producing ATP. Riboflavin also helps maintain healthy skin, eyes, and red blood cells and has antioxidant properties. Riboflavin is important for collagen production and helps maintain the skin's moisture barrier, making it a vital B-vitamin for skin health. Infini-B includes the highly absorbable and active form of riboflavin, Riboflavin 5’-Phosphate.*

Niacin (Vitamin B3): Niacinamide + Inositol hexanicotinate

Niacin is a crucial vitamin for energy production from macronutrients, similar to thiamin and riboflavin. It acts as a precursor to NAD+, a molecule that plays a key role in energy production. Additionally, niacin helps to process cholesterol, increasing HDL cholesterol and decreasing LDL cholesterol levels. It also has distinct blood flow promoting properties, mood-boosting effects, neuroprotective properties and it is important for the production of myelin!*

Infini-B contains two forms of niacin, niacinamide and inositol hexanicotinate, both of which are referred to as "no-flush niacin". These forms of niacin do not cause the flushing reaction commonly associated with plain niacin, making them more tolerable for many people. Niacinamide and inositol hexanicotinate have great bioavailability, and inositol hexanicotinate has the unique attribute of slowly releasing niacin, increasing niacin levels over a longer period of time!*

Pantothenic Acid (Vitamin B5): D-Calcium Pantothenate

Pantothenic acid is very important for energy production. Pantothenic acid achieves this by generating coenzyme A (CoA), a carrier molecule that shuttles macronutrient breakdown products for energy production, including acetyl groups for ATP synthesis in the citric acid cycle. CoA, via acetyl-CoA, is also important for cognition because acetyl-CoA is crucial to the synthesis of acetylcholine, a neurotransmitter involved in cognitive function. Pantothenic acid is also important for red blood cells by synthesizing heme and maintaining structural integrity. Infini-B uses D-calcium pantothenate for its stability and bioavailability.*

Pyridoxine (Vitamin B6): Pyridoxal 5' - Phosphate (P5P)

Pyridoxine is essential for energy production by converting carbohydrates, proteins, and fats into usable energy and contributing to the production of hemoglobin for oxygen delivery to cells. It also plays a role in neurotransmitter synthesis by participating in enzymatic reactions required for the breakdown and utilization of amino acids, which are the building blocks of neurotransmitters. Pyridoxal-5-phosphate (P5P), the active form of pyridoxine, is necessary for the synthesis of several neurotransmitters, including serotonin, dopamine, and GABA. It is also important for regulating prolactin levels, which can affect mood, sleep, and focus. Infini-B utilizes the highly bioavailable and active form of vitamin B6, P5P.*

Biotin (Vitamin B7): Biotin

Biotin is essential for the body's energy production, activating enzymes involved in the metabolism of carbohydrates and fats. It is also required for healthy skin, hair, and nails by promoting the production of keratin and supporting the growth of skin cells. However, high doses of biotin can lead to breakouts which might be due to its ability to stimulate the production of sebum, and/or inhibiting the uptake of pantothenic acid which is also very important for skin health. Due to this, we only included a very small dose of vitamin B7 in Infini-B, as just plain biotin because it absorbs well.*

Folate (Vitamin B9): L-5-Methyltetrahydrofolate Calcium

Folate is essential for DNA synthesis and repair, and necessary for the conversion of homocysteine into methionine for nucleotide synthesis. Folate plays a critical role in DNA methylation, stabilizing damaged DNA and preventing mutations. Folate is important for cell growth and division, and red blood cell formation. Folate is also necessary for methylation and the synthesis of SAMe, which is a universal methyl donor. Additionally, folate is important for the synthesis of neurotransmitters, including serotonin, dopamine, and norepinephrine, which require SAMe as a co-factor. Folate is also crucial for maintaining neuronal structure and supporting brain cell growth. Infini-B uses L-5-Methyltetrahydrofolate Calcium (L-5-MTHF-Ca) as its folate source because it is the active and bioavailable form of folate, directly usable by the body without conversion by the liver. It is considered superior due to its bioavailability, stability, and ability to support optimal brain and neurological function.*

Cobalamin (Vitamin B12): Methylcobalamin + Hydroxycobalamin

Cobalamin is crucial for various bodily functions, including the synthesis of neurotransmitters such as dopamine, serotonin, and norepinephrine. It is also involved in methylation, the production and maturation of red blood cells, and energy production through the metabolism of fatty acids and amino acids. SAMe, a coenzyme synthesized from methionine, is also dependent on cobalamin for its production, and regulation of neurotransmitters. Infini-B utilizes two of the most bioavailable and active forms of cobalamin, methylcobalamin and hydroxocobalamin.*

Infini-B Benefits & Uses

    • Enhances energy production from food*
    • Promotes neurotransmitter synthesis*
    • Boosts energy levels*

The Ultimate B-Complex

Taken together, all eight B-vitamins create an incredible effects profile focused on energy production from food, neurotransmitter synthesis and cardiovascular function. Since the B-vitamins need to be constantly replenished due to their high water solubility, it makes a lot of sense to look towards a high quality B-complex, especially if you want to boost your energy levels and cognitive function. However, high quality B-complexes appear to be few and far between. With Infini-B we set out to change this, aiming for a B-complex utilizing the best forms of B-vitamins whilst utilizing proper dosing levels. After a lot of research and development, accompanied by an enormous amount of beta-testing and formulating, we believe we have indeed achieved this goal!*

Now you are probably wondering, what does it feel like? Well, since we did so much beta-testing, we can tell you exactly what it feels like! If you happen to be deficient in any of these B-vitamins, Infini-B is going to have some very profound results the first time you take it. It will give a very pleasant natural feeling stimulating effect, accompanied by a significant lift in mood and mental sharpness.* Physically, it will also feel like you got a surge of energy, allowing you to channel that energy into physical activities!* If you aren’t currently deficient in these B-vitamins, the effects will be quite a bit milder. However, the energizing and mood boosting effects were still there, even for those of us who had already been taking B-vitamins from other sources!*

Infini-B Stacks

Metabolic Stack: Infini-B + OptimALA Capsules

Similar to B-vitamins, alpha-lipoic acid also plays a role in energy production from food. This is in addition to its positive mitochondrial effects! With OptimALA we took alpha-lipoic acid and optimized it a lot, and due to this, we think it is a fantastic match with a highly optimized B-complex!*

Dopamine Stack: Infini-B + L-Tyrosine Capsules

A variety of the B-vitamins in Infini-B, such as P5P, methylcobalamin, hydroxycobalamin and L-5-Methyltetrahydrofolate Calcium all aid in the synthesis of dopamine. Therefore, it makes sense to stack infini-B with the main precursor for dopamine, L-tyrosine! Expect even more energy, focus and mood boosting with this stack!*

Acetylcholine Stack: Infini-B + Cognizin Citicoline Capsules

A variety of the B-vitamins in Infini-B, such as D-calcium pantothenate, benfotiamine and thiamine HCL all play a role in acetylcholine synthesis. With this in mind, it made perfect sense to stack Infini-B with one of the best choline sources, cognizin! Taken together, Infini-B and cognizin make for a fantastic nootropic stack!*

Cardiovascular Stack: Infini-B + CoQH-CF Softgels

B-vitamins generally are very important for cardiovascular function, which is why we like combining it with the ubiquinol form of Coenzyme Q10, which has some fantastic effects on cardiovascular function! CoQH-CF also has fairly energizing effects, which stack very nicely with the energizing effects of Infini-B!*

Infini-B Dosage

As a dietary supplement, take one capsule of Infini-B daily.
