Why choose active vitamin B from Jigsaw Health

B vitamins are among the essential nutrients your body relies on continuously – in every cell, every day, day and night. They play a key role in energy production, nervous system function, mental resilience and hormonal balance. As they are water-soluble, the body cannot store them, making regular intake essential – especially during periods of increased demand.

However, it is not only about how much vitamin B you take, but primarily in which form and how long it remains available to the body. This is precisely where Jigsaw Health Activated B w/SRT^® differs fundamentally from standard B-complex supplements.

A detailed explanation of these differences, including a comparison with more conventional B-complexes (such as Woldohealth), can be found in the Frequently Asked Questions (FAQs) section at the end of the product description.

What does “active form” of vitamin B and the w/SRT^® designation mean?

Most standard B-complex supplements contain so-called inactive forms of vitamins, which must first be converted in the liver before the body can fully utilise them. For some individuals – particularly under long-term stress, fatigue or due to genetic variations – this conversion may be less efficient.

Jigsaw Health Activated B w/SRT^®, by contrast, provides active (bioidentical) forms of all B vitamins, ready for immediate use without the need for further metabolic conversion.

It also features the patented SRT^® – Sustained Release Technology, meaning sustained release. Instead of being released all at once, the vitamins are delivered progressively over several hours, helping to maintain a more stable level of B vitamins throughout the day.

Why Activated B w/SRT^® is different from standard B-complexes

• Uses exclusively active forms of B vitamins that the body can utilise directly.
• Is gentler on metabolism, as it does not burden the liver with conversion processes.
• Thanks to SRT^® technology, provides sustained release and a stable effect throughout the day.
• Label claims are verified by an independent third party.

How Activated B w/SRT^® may support you

• Supports stable energy levels without sharp fluctuations during the day.
• Contributes to mental clarity, focus and cognitive endurance.
• Supports proper function of the nervous system, heart and digestion.
• Plays a role in the body’s natural detoxification processes.
• Helps maintain a balanced stress response.
• Contributes to hormonal balance.
• Ensures adequate intake of vitamin B12 in its active form.

Quality and trust statement

Jigsaw Health follows a simple philosophy: a supplement should be designed to be truly functional, not merely look good on a label. That is why the brand focuses on active forms, transparent formulations and independent quality verification.

The Jigsaw Health brand

Frequently Asked Questions (FAQs)

What is the difference between active and inactive forms of B vitamins?

Inactive forms of B vitamins (for example, thiamine HCl or standard riboflavin) must first be metabolically converted, most commonly in the liver, before they become biologically usable.

Active forms (such as benfotiamine, riboflavin-5-phosphate, pyridoxal-5-phosphate, methylcobalamin or Quatrefolic^®) are already in a usable form and do not require further enzymatic conversion. This typically means faster, more efficient and more reliable utilisation – especially for people under increased strain or with a reduced capacity for metabolic conversion.

Why is SRT^® technology so important in Jigsaw Health?

B vitamins are water-soluble and, when released all at once, are excreted from the body relatively quickly. SRT^® (Sustained Release Technology) delivers the vitamins gradually throughout the day, so they remain available to the body for longer.

The result is a more even level of B vitamins, steadier energy during the day and better overall use of each dose.

Can Jigsaw Health Activated B w/SRT^® support fatigue and stress?

Yes. B vitamins are essential for cellular energy production, healthy nervous system function and neurotransmitter synthesis. Users often report steadier energy, improved focus and a lower sense of mental and physical fatigue, particularly during periods of long-term stress.

How long does it take to notice an effect?

Because the formula uses active forms, absorption and utilisation are typically quicker than with standard B-complex products. Many people notice early changes within 1–2 weeks of consistent use. Timing can vary depending on baseline nutrient status, lifestyle and overall demand on the body.

Can this product replace other B-complexes or a separate vitamin B12 supplement?

In many cases, yes. Thanks to its comprehensive profile and active forms, Jigsaw Health Activated B w/SRT^® may replace multiple single supplements. If you have specific health concerns, it is always sensible to discuss supplementation with a qualified professional.

Is this B-complex suitable for long-term use?

Yes. Active forms and sustained release can be suitable for longer-term supplementation, especially for people under increased mental or physical strain. It is reasonable to monitor B vitamin status over time, particularly B12 and folate, where appropriate.

Is Jigsaw Health Activated B w/SRT^® suitable during pregnancy?

Jigsaw Health Activated B w/SRT^® contains active forms of B vitamins, including active folate (Quatrefolic^®) and methylcobalamin (vitamin B12), which are widely regarded as high-quality, biologically usable forms.

That said, this is a higher-strength, targeted formula. During pregnancy, supplementation should always be discussed with a doctor or midwife, who can assess individual needs and medical context.

Is it suitable while breastfeeding?

B vitamins play an important role during breastfeeding, contributing to energy metabolism and nervous system function. Activated B w/SRT^® may be appropriate in this period, particularly where long-term fatigue or stress is present.

Given the higher strength and active forms, it is still advisable to consult a healthcare professional so supplementation can be tailored to individual needs.

Is this B-complex suitable for children?

This product is primarily intended for adults. Its dosing and formulation are designed for adult requirements and are not optimised for children.

For children, it is generally better to choose a product formulated specifically for paediatric use, and to discuss supplementation with a paediatrician where needed.

Who is Jigsaw Health Activated B w/SRT^® best suited for?

This B-complex is best suited for people under increased mental or physical strain, especially those who do not feel consistent benefits from standard B-complex products.

• people exposed to long-term stress or mental overload
• athletes and physically active individuals
• those with demanding work schedules
• people who prefer active vitamin forms without the need for metabolic conversion
• individuals who tend to excrete standard B vitamins quickly

Who might be better served by a different type of B-complex?

If you are looking for basic, general B vitamin top-up without the need for higher bioavailability or sustained release, a simpler and lower-strength B-complex may be sufficient.

Activated B w/SRT^® is a targeted option for situations where functionality, stability of effect and maximum utilisation are the priority.

Is Jigsaw Health Activated B w/SRT^® suitable for biohackers?

Yes. Activated B w/SRT^® is often chosen by biohackers and those who take a systematic approach to optimising energy, cognitive performance and long-term nervous system resilience.

From a biohacking perspective, the key advantages are the use of active forms of B vitamins that do not require additional conversion, and sustained release (SRT^®), which helps avoid sharp peaks and dips in availability.

Biohackers typically pay attention to bioavailability, absorption kinetics, stability of effect and metabolic load. In this context, Activated B w/SRT^® is often viewed as a functional tool rather than a standard multivitamin.

As always, an individual approach matters. It can be sensible to align use with your wider supplement routine and, where relevant, validate decisions with lab markers.

Expert comparison: Jigsaw Health vs. Woldohealth Bioactive B-Complex

How to understand the difference in practice

Jigsaw Health Activated B w/SRT^® is formulated for maximum bioavailability, minimal losses during absorption, and a consistently stable effect over time. It uses active forms of all key B vitamins and sustained-release delivery to provide steady support throughout the day.

Woldohealth Bioactive B-Complex is a more affordable option that combines some active forms with standard forms and does not use controlled-release delivery. It can work well for basic supplementation, but it is not designed for targeted support under long-term high demand.

Recommendation from an expert perspective

If you are looking for a truly functional B-complex with a focus on absorption, stability of effect and long-term efficiency, Jigsaw Health Activated B w/SRT^® represents a higher level in both formulation and delivery. The price difference reflects the difference in active forms and the technology used.
