Doctor's Best Fully Active B Complex, Non-GMO, Gluten & Soy Free, Vegan, Supports Energy Production, 30 Count

Description:

About this item:

  • FULLY ACTIVE B COMPLEX - contains all eight important B vitamins - full spectrum designed for optimal absorption and utilization to support overall health and well-being. Water-soluble B vitamins play important roles in cell metabolism, supporting DNA, organs, genes, cells, tissues, skin health, immune system, enzyme functions and energy production.*
  • Product Note: Exposure to heat or sunlight may lead to melting/damage of product. Hence customers are expected to be available during the product delivery
  • CONTAINS QUATREFOLIC – is the glucosamine salt of (6S)-5-methyltetrahydrofolate, the most bioavailable form of folate, that provides greater stability and water solubility.* Folate is an essential vitamin to support DNA, proper cell division, cardiovascular, mental and emotional well-being.*
  • CONTAINS QUATREFOLIC – is the glucosamine salt of (6S)-5-methyltetrahydrofolate, the most bioavailable form of folate, that provides greater stability and water solubility.* Folate is an essential vitamin to support DNA, proper cell division, cardiovascular, mental and emotional well-being.*
  • ENERGY SUPPORT - provides B vitamins that work together to convert food into energy. Helps support proper metabolism of carbohydrates, fat, and protein.*
  • NERVOUS SYSTEM SUPPORT - helps support nerve function.* Vitamin B6 (pyridoxine HCl and pyridoxal 5' phosphate) supports a healthy nervous system. Vitamin B6 is vital for early brain development and for the metabolism of various brain chemical transmitters. Nerve cells both in the brain and elsewhere in the body rely on Vitamin B6.*
  • CLINICAL RESEARCH – shows that B vitamins are important for DNA and protein synthesis and therefore healthy cell growth and development.* This full spectrum supplement is fully optimized for safety and efficacy and is an excellent way to ensure that the body's needs for B vitamins are being satisfied..During the summer months products may arrive warm but Amazon stores and ships products in accordance with manufacturers' recommendations, when provided.
  • The breakthrough features of this formulation include: supplies only the best-utilized b vitamin forms. Most b vitamin supplements use cheap forms that are not optimally utilized in the body. This formulation does not compromise-it provides generous amounts of the most active b vitamins. Substitutes naturally fully active folate for synthetic folic acid. Folic acid is an artificial folate that is difficult for the body to assimilate. This formulation instead provides the body's most fully active folate, MTHF (methyl-tetra-hydro-folate). Provides sufficient, fully active vitamin B12. Very few supplements provide sufficient amounts of active vitamin B12. This formulation provides 1000 micrograms of fully active B12 to help ensure excellent oral absorption. Thiamin ("vitamin B1") is fundamental to human metabolism because it is essential for the metabolism of oxygen. The microscopic "power plants" of our cells (mitochondria) require thiamin to generate energy, but elsewhere in the cells it is also required for energy generation. Thiamin is important for metabolizing amino acids, the building blocks of proteins, but is especially important for managing sugar and other carbohydrates, and can be depleted by high-carbohydrate diets. Thiamine even helps support the delicate blood vessels of the retina and other tissues in the presence of high levels of circulating blood sugar. This vitamin is absorbed only as thiamin (not as other thiamin vitamins) in the upper small intestine. Alcohol can impair the proteins that transport thiamin, and high alcohol consumption is linked to thiamine deficiency. The brain and other nervous tissues have especially high thiamin requirements. Other organs with high oxygen requirements, such as the heart, also have high demand for thiamine.

    Trusted brand and easy way to get B vitamins for better energy throughout the day. I’m happy it includes niacin because that seems to help with energy production. I haven’t noticed a strong smell. I always eat breakfast before I take these to avoid a niacin flush. Very good.

    5.0 out of 5 stars Good brand

    N.A. · July 8, 2024

    Great supplements. Only complaint is that I wish they were divisible into half or thirds (as recommended by Novos labs who links to this product) due to the large dosage. I just take every other day but halving it would be great. Still a wonderful product!

    As a plant based eater, I have taken a vegan B12 supplement for years. Recently, I ran out and was “too busy” to order more. After a couple months, I noticed having low energy especially in the afternoons and then started having heart palpitations. I went to the doctor to be safe, and confirmed that everything was good except my B12 was on the bottom end of the “normal range.” I ordered this B complex, and within less than 2 weeks of taking it daily, the palpitations were gone and energy is coming back. Lesson learned. This is a great oral supplement and seems to be very effective without any negative side effects.

    Qualidade e dosagem excelentes

    The product is fantastic, I used to buy from Ebay, Australia but prices have been going up. Even paying for freight and gst on top of this Bolo AU price, Its a good price which is equivalent for AU$17 for 30 days supply, whereas Ebay Aust was $27 for 30 days.NIACIN FLUSHING I do get this occasionally, it does no harm whatsoever, it is not a fault of the capsules. When the pills are fresh, it sometimes happens. My face and neck get a bit red and theres a slight tingle like sunburn,but its all over in 15 minutes. Look up Dr Ben Lynch articles, so many people think there is something wrong with the capsules if they have a flush. I normally take straight after breakfast, I try and take with half glass of water, however sometimes I take with a warm mild coffee. If I forget my pill and its past 3pm, I will not take it, as I believe it could affect my sleep.Ive had other folate supplements, but I love the other B's in this Complex, I really benefit from Riboflavin and all the other B's in this complex are in a good absorbable form.I sometimes top up with Doctors Best 400 mcg folate but I have not noticed much benefit with them.I have only given 4 stars as I felt my order was not despatched immediately, it was several days after the order & from date of order to arrival in Australia it was 24 days. Unlike Ebay, I did not know who to contact to chase up.
