Performance

Approved Science Methylated B Complex features what we consider to be a near-perfect formula for supporting healthy methylation. With all B vitamins in their active or methylated forms, plus additional methyl donors, it’s designed to promote optimal cellular function, DNA repair, neurotransmitter production, and homocysteine balance. Whether you’re looking to support energy levels, mood, mental clarity, or cardiovascular health, this formula delivers.

What makes this formula so effective? Let’s take a deeper look at the ingredients, especially through the lens of how they support methylation and overall biochemical function.

  • Vitamin B1: Helps turn food into energy and supports your nerves.

  • Vitamin B2: Keeps your cells healthy and helps your body use other B vitamins.

  • Vitamin B3: Supports your skin, digestion, and energy levels.

  • Vitamin B5: Helps with stress support and energy production.

  • Vitamin B6: Plays a big role in mood balance, brain health, and how your body processes protein.

  • Biotin (B7): Known for supporting hair, skin, and nails—but also helps your body use nutrients.

  • Folate (B9) – in the methylated form Quatrefolic®: This is the form your body can use right away, and it’s key for healthy blood, brain function, and DNA.

  • Vitamin B12 – includes Methylcobalamin & Adenosylcobalamin: These work together to support energy, nerve health, and proper methylation.

Also included are:

  • Betaine (Trimethylglycine): A methyl donor that helps lower homocysteine levels and assists liver detox pathways.

  • Choline: Supports brain health and acts as a cofactor in methylation processes by converting to Betaine in the liver.

This isn’t just a B complex—it’s a complete methylation support formula, and Approved Science nailed it.

FAQs about Approved Science Active Methylated B Complex:

How does Approved Science’s B Complex work?

It provides your body with all essential B vitamins in active forms plus added methyl donors (Betaine and Choline), ensuring efficient methylation and support for energy, brain, liver, and cardiovascular function.

Do all Methylated B complexes work in a similar way?

Not all Methylated Vitamin B complexes are created equal. While some brands jump on the trend, they often cut corners, offering formulas that lack proper balance or don’t include all 8 essential B vitamins. Even worse, many use synthetic forms of vitamins that require your body to convert them into active forms. Unfortunately, many people have genetic mutations that hinder their ability to do this conversion effectively, leaving synthetic vitamins less effective. Active, bioavailable forms, on the other hand, are immediately usable by the body and provide better results, making them the superior choice for everyone.

What should I look for in an effective Methylated B Complex?

  • Full Spectrum Vitamins – Make sure all 8 B vitamins are included in the formula.
  • Active & Bioavailable Forms – Look for methylated forms like methylcobalamin (B12) and 5-MTHF (B9), plus highly bioavailable pyridoxal-5-phosphate (B6).
  • Stability – For Folate (B9), we recommend Quatrefolic®, a patented version of this vitamin that is stable and highly bioavailable.
  • Balanced Dosage – Each B vitamin should be present in clinically effective amounts, ideally over 100% of the Daily Value (DV) for therapeutic dosages.
  • Added Choline & Betaine – A compound that complements the effects of methylated vitamins in repairing DNA, detoxing, producing neurotransmitters.
  • Reputable Brand – Choose a company with positive customer feedback and strong brand credibility.
  • Purity and Authenticity – Ensure the supplement is third-party tested for quality and free of unnecessary additives.
  • Certifications – Look for GMP-certified, non-GMO, and third-party-tested products.
  • Money-Back Guarantee – A trustworthy company stands behind its product with a risk-free return policy.

Are there any side effects noted when using this product?

B vitamins are water soluble and aren’t stored in the body, therefore, they are generally considered safe at recommended dosages. Nevertheless, dosages that are too high can cause undesirable side effects. Approved Science’s Methylated B complex has carefully selected dosages that are unlikely to cause side effects. However, as with any supplement, it’s essential to consult with a healthcare professional before starting Vitamin B supplementation to ensure it’s appropriate for your individual health circumstances.

What are the dosage instructions for Approved Science Active Methylated B Complex?

The manufacturers of this product suggest taking 2 capsules per day (one in the morning and one in the afternoon) with meals and an 8 oz. glass of water. 

As with any medication or supplement, always follow the recommended dosage instructions and do not exceed them as this poses health risks.

How long before I can see any results?

The time it takes to see results from using Approved Science Methylated B Complex can vary depending on individual factors such as your current health, diet, lifestyle, and any underlying conditions. However, many users start to experience noticeable improvements in energy levels, mood, and mental clarity within 1-2 weeks of consistent use. For more significant benefits, it may take around 3-4 weeks.

As with any supplement, it’s important to give your body time to adjust and absorb the nutrients fully. For the best results, combine the supplement with a balanced diet and a healthy lifestyle.

What price should I expect to pay for Approved Science Active Methylated B Complex?

The cost varies based on the number of bottles you order. While a single bottle costs $49.95, if you order a 6-month supply, you can purchase the product for under $25 for each month’s supply. You never have to worry about being subscribed or charged without your knowledge and you’re protected by the Approved Science 60-day 100% money-back guarantee so there’s nothing to lose by buying in bulk.

Which Methylated B Complex should I buy?

As each person’s experience of a product is different, it is difficult to say specifically which one is the best. That said, based on several factors, we did like Approved Science Methylated B Complex the most. We found that from 50+ products that we looked at, Approved Science Methylated B Complex had the best quality of ingredients, potency and strength, and positive consumer feedback; plus the manufacturer’s customer service was excellent.

How safe is it to order over the internet?

Approved Science Methylated B Complex is safe to be ordered over the internet. The manufacturer utilizes the latest encryption software to protect your credit card information and does not engage in shady schemes such as ‘automatic billing’ programs like many other companies do.
