- High-quality, third-party tested for purity and potency

NOW Supplements Folic Acid 800 mcg + B-12 25 mcg is a targeted B-vitamin supplement designed to support cardiovascular and nervous system health. It is particularly beneficial for individuals looking to maintain healthy homocysteine levels, which is crucial for heart health. This product is ideal for those who want a focused dose of folate and B-12 without other B-vitamins, making it a versatile addition to any supplement regimen.
The standout feature of this supplement is its role in homocysteine metabolism. Folic acid and B-12 work together to convert homocysteine into methionine, an amino acid essential for various bodily functions. This process supports cardiovascular health and helps maintain proper nervous system function. Additionally, folic acid is vital for DNA synthesis and red blood cell production, making it especially important for rapidly dividing cells.
In terms of quality, NOW has a strong reputation for manufacturing supplements under strict GMP guidelines. The product is third-party tested for stability, potency, and formulation, ensuring you receive a consistent and reliable dose. The tablets are easy to swallow, though they have a yellow/beige color with orange speckles, which is normal for this type of product.
One potential drawback is that this supplement contains only folic acid and B-12, not a full B-complex. If you are looking for a comprehensive B-vitamin blend, you may need to consider a different product. Also, some individuals may experience mild digestive upset when taking B-vitamins on an empty stomach, but this can be avoided by taking it with food.
Overall, NOW Folic Acid 800 mcg + B-12 25 mcg is a high-quality, affordable option for those needing targeted support for homocysteine metabolism and red blood cell health. Its trusted brand reputation and third-party testing make it a reliable choice. I recommend this product for anyone seeking to support their cardiovascular and nervous system naturally.

Buying Guide: What to Look for in a B12 and Folic Acid Supplement
Not all B12 and folic acid supplements are created equal. To choose the right one for your needs, consider these key factors.
Form of Vitamin B12: Methylcobalamin vs. Cyanocobalamin
The body uses B12 in its active form, methylcobalamin. Many supplements contain cyanocobalamin, a synthetic form that must be converted in the liver. For maximum bioavailability, look for methylcobalamin, especially if you have absorption issues. Products like Life Extension BioActive Folate and Vitamin B12 use this active form.
If you are on a tight budget, cyanocobalamin works well for most people. The NOW Supplements option uses this form and is still highly rated.
Folate Form: Folic Acid vs. 5-MTHF
Folic acid is the synthetic form of vitamin B9. While effective, some people have a genetic variation (MTHFR) that prevents proper conversion. The bioactive form, 5-methyltetrahydrofolate (5-MTHF), bypasses this step. Life Extension and NatureWise offer 5-MTHF for better absorption.

Additional B Vitamins and Nutrients
A comprehensive B-complex provides synergistic benefits. Vitamins B1, B2, B3, B6, and biotin support energy metabolism and nerve function. Nature Made Super B Complex includes all eight B vitamins plus vitamin C for immune support. If you want a complete daily boost, this all-in-one approach saves time and money.
For beginners just starting with supplements, we recommend our Top Energy & Stamina Supplements for Beginners guide.
Dosage and Convenience
Check the serving size. Most products provide 400 to 800 mcg of folic acid and 25 to 1,000 mcg of B12 per tablet. Fast-dissolve tablets, like Vitamatic Folic Acid 400 mcg with B6 & B12, are ideal for those who dislike swallowing pills. Softgels and capsules are also easy to take. Consider your daily routine: a once-daily tablet is simplest for consistent use.

Frequently Asked Questions
Can I take vitamin B12 and folic acid together?
Yes, these two nutrients work synergistically. Vitamin B12 helps activate folic acid in the body, and together they support red blood cell production, homocysteine metabolism, and neurological function. Many supplements combine them for convenience.
What is the best form of vitamin B12 for absorption?
Methylcobalamin is the biologically active form and is generally considered the most absorbable. Cyanocobalamin is a synthetic form that the body must convert; it is effective but may be less ideal for those with absorption issues. For 2026, many top-rated products use methylcobalamin.
How much folic acid and B12 should I take daily?
The recommended dietary allowance for folic acid is 400 mcg DFE for most adults, and for B12 it is 2.4 mcg. However, many supplements provide higher doses (e.g., 800 mcg folic acid and 1,000 mcg B12) to support energy and heart health. Always follow the label instructions and consult a healthcare professional if you have specific concerns.
Are there any side effects of taking B12 and folic acid?
Both are water-soluble vitamins, so excess is usually excreted in urine. Side effects are rare but may include mild digestive upset. High doses of folic acid can mask a B12 deficiency, so it is important to take them together. For more on energy supplements for men over 50, visit our Top Energy Pills for Men Over 50 page.
