Deep dive into Designs for Health B-Supreme: coenzymated B vitamins with Quatrefolic® folate, TMG, and Choline for methylation, energy, and nervous system support.

Product Overview

What Is Designs for Health B-Supreme?

Designs for Health B-Supreme is a comprehensive B-complex formula that delivers most of its B vitamins in their coenzymated (active) forms. Because these forms are already phosphorylated, they are more readily available for the body to use in biochemical reactions without requiring additional conversion steps.

B-Supreme also includes the patented folate derivative Quatrefolic®, an innovative form of folate that has demonstrated high bioavailability, solubility, and long-lasting stability. To further support methylation pathways, the formula incorporates both trimethylglycine (TMG) and Choline — two methyl donors that work alongside the B vitamins to maintain healthy one-carbon metabolism.

This vegan, non-GMO formula is free from gluten, dairy, and soy, making it accessible to a wide range of dietary preferences. Each bottle contains 60 capsules, with a serving size of just one capsule per day.

Why It Matters

Methylation, Energy, and Nervous System Health

The B vitamins are central to some of the body's most essential biochemical processes. Research suggests they play critical roles in cellular energy production, nervous system function, and the methylation cycle — a metabolic pathway that influences DNA repair, neurotransmitter synthesis, and homocysteine metabolism.

Many people may not efficiently convert standard B vitamins into their active coenzyme forms due to genetic variations or other factors. Designs for Health B-Supreme addresses this by supplying most B vitamins in their bioactive, coenzymated or methylated forms, supporting superior absorption and utilization.

The addition of TMG and Choline provides methyl group donors that operate through pathways independent of, yet complementary to, the folate and B12 methylation cycle. This multi-pathway approach helps ensure robust methylation support.

What's inside

Key ingredients

Thiamin — 100 mg

Vitamin B1 (thiamin) is an essential cofactor for pyruvate dehydrogenase and alpha-ketoglutarate dehydrogenase — key enzymes that couple glycolysis to the TCA cycle and enable mitochondrial ATP production from glucose. Research confirms that thiamin contributes to normal energy-yielding metabolism and supports the reduction of tiredness and fatigue. Thiamin is also classified as a neurotropic vitamin, required as a cofactor in glucose metabolism that indirectly supports the synthesis of neurotransmitters, myelin, and nucleic acids in the nervous system. Studies show it is directly required for the synthesis of acetylcholine and modulates GABA and glutamate levels. Deficiency causes severe neurological disorders including Wernicke's encephalopathy and peripheral neuropathy.

Riboflavin — 50 mg

Vitamin B2 (riboflavin) is the precursor to the coenzymes FAD and FMN — essential electron carriers in the mitochondrial respiratory chain required for oxidative phosphorylation and ATP production. FAD directly accepts electrons at Complex II of the electron transport chain, making riboflavin indispensable for cellular energy. Riboflavin is also the obligate coenzyme (as FAD) for methylenetetrahydrofolate reductase (MTHFR), the enzyme that generates 5-MTHF for homocysteine remethylation. Studies demonstrate that riboflavin supplementation specifically lowers homocysteine in individuals homozygous for the MTHFR 677C>T polymorphism. Riboflavin deficiency impairs MTHFR activity, reduces 5-MTHF levels, and elevates homocysteine. It is also essential for neuronal energy metabolism, and riboflavin transporter deficiency causes severe progressive neuropathy responsive to high-dose riboflavin.

Niacin — 50 mg

Vitamin B3 (niacin) is the dietary precursor to NAD+ and NADP+ — coenzymes that drive over 500 enzymatic reactions including glycolysis, the TCA cycle, and oxidative phosphorylation. Research shows niacin supplementation in mitochondrial disease raises cellular NAD concentrations up to 24-fold and enhances Complex I substrate availability for ATP production. Niacin is essential for NAD+ synthesis, which is critical for neuronal energy metabolism, DNA repair, and survival of neurons. Severe deficiency causes pellagra with neurological manifestations including confusion and dementia. Niacin also spares tryptophan from the kynurenine pathway, preserving its availability for serotonin synthesis.

Vitamin B6 — 50 mg

Vitamin B6 (pyridoxine), in its active form pyridoxal-5'-phosphate (PLP), is a cofactor for over 100 enzymatic reactions including amino acid metabolism, glycogen breakdown, and neurotransmitter biosynthesis. PLP is the essential coenzyme for decarboxylation reactions producing serotonin, dopamine, and GABA — critical neurotransmitters for mood and cognitive function. B6 supports methylation by enabling the transsulfuration pathway via cystathionine beta-synthase (CBS), converting homocysteine to cystathionine and glutathione. This clears homocysteine from the methylation cycle and supports methionine production for SAMe synthesis. Studies confirm B6 contributes to normal energy-yielding metabolism and the reduction of tiredness and fatigue. B6 is also required for heme biosynthesis via delta-aminolevulinic acid synthase, supporting healthy red blood cell formation.

Folate — 340 mcg (as Quatrefolic®)

This formula features Quatrefolic®, a patented form of folate that has demonstrated high bioavailability, solubility, and long-lasting stability. Folate is the principal nutrient involved in homocysteine remethylation — as 5-methyltetrahydrofolate, it donates a methyl group to convert homocysteine to methionine. Numerous RCTs confirm folate supplementation significantly reduces plasma homocysteine. Folate facilitates the transport of methyl groups in the one-carbon pathway for DNA methylation and homocysteine remethylation. Deficiency produces global hypomethylation and impaired SAMe synthesis. Folate is also essential for nervous system development and maintenance, critical for one-carbon methylation supporting neurotransmitter synthesis, and is required for DNA synthesis and red blood cell maturation. Deficiency causes megaloblastic anemia and fatigue.

Vitamin B12 — 250 mcg

Vitamin B12 (cobalamin) is essential as a cofactor for methionine synthase, which remethylates homocysteine to methionine using 5-MTHF, directly sustaining the SAMe/methylation cycle. B12 deficiency stalls this reaction, trapping folate in the methyl-folate trap and elevating homocysteine. Research shows B12 supplementation with at least 0.4 mg daily lowers homocysteine by approximately 7% as a standalone effect, with greater reductions in combination with folate and B6. B12 is also critically required for myelin synthesis, DNA synthesis, and fatty acid metabolism in nerve cells — its deficiency is one of the most common and clinically recognized reversible causes of peripheral neuropathy. Additionally, B12 is required for methylmalonyl-CoA mutase, which converts propionyl-CoA to succinyl-CoA — a direct TCA cycle intermediate — thereby sustaining mitochondrial ATP production.

Biotin — 2000 mcg

Vitamin B7 (biotin) is an essential coenzyme for five carboxylase enzymes involved in fatty acid synthesis, gluconeogenesis, and amino acid catabolism — all central to energy homeostasis. Without adequate biotin, these enzymes cannot function, making it indispensable for normal metabolic processes. Biotin is also the cofactor for mitochondrial carboxylase enzymes including pyruvate carboxylase (TCA cycle anaplerosis), propionyl-CoA carboxylase (branched-chain amino acid and odd-chain fatty acid catabolism), and methylcrotonyl-CoA carboxylase — all localized in the mitochondrial matrix and essential for mitochondrial metabolic flux.

Pantothenic Acid — 100 mg

Vitamin B5 (pantothenic acid) is the precursor to Coenzyme A (CoA), which is required for the activation of acetyl groups entering the TCA cycle, fatty acid beta-oxidation, and the synthesis of ATP-precursor substrates. Without B5, cellular energy metabolism cannot proceed. Studies confirm pantothenic acid contributes to normal energy-yielding metabolism and the reduction of tiredness and fatigue. B5 is also essential for the synthesis of acetylcholine, the primary neurotransmitter enabling nervous system communication. Experimental B5 deficiency in humans produces neurological symptoms including paresthesia, muscle weakness, and impaired coordination.

Choline — 200 mg

Choline is an essential nutrient that serves as a direct precursor to the neurotransmitter acetylcholine, which is critical for memory, attention, and mental alertness. Choline is also the metabolic precursor to betaine (trimethylglycine) — through Choline dehydrogenase oxidation, it is converted to betaine, which donates methyl groups to homocysteine via BHMT, supporting SAMe regeneration. Choline deficiency reduces hepatic SAMe and impairs methylation. Additionally, Choline is required for the synthesis of phosphatidylcholine, which enables hepatic VLDL secretion and fat export from the liver. Higher dietary Choline intake is associated with lower circulating homocysteine concentrations.

TMG (trimethylglycine) — 200 mg

TMG is chemically identical to betaine and supports methylation as a direct methyl donor via betaine-homocysteine methyltransferase (BHMT), converting homocysteine to methionine independently of folate and B12. Meta-analysis of RCTs confirms it reliably lowers plasma homocysteine. TMG replenishes SAMe through the methionine cycle, and SAMe is the obligate methyl donor for synthesis of serotonin, dopamine, and norepinephrine in the brain. By supporting SAMe availability, TMG indirectly sustains neurotransmitter synthesis and mood-related neurochemistry. TMG also functions as an organic osmolyte, protecting cells from osmotic stress and preserving cellular hydration while maintaining the integrity of macromolecular functions.
