  • 5-MTHF folate bypasses the MTHFR enzymatic conversion that approximately 40% of the population performs inefficiently, ensuring biologically active folate reaches the methylation cycle regardless of genetic status
  • Methylcobalamin is the neurologically active form of B12, supporting nerve function, red blood cell formation, and DNA synthesis without requiring the conversion steps that cyanocobalamin demands
  • L-OptiZinc chelates zinc to the amino acid methionine for superior intestinal absorption and tissue retention, supporting immune function, skin health, and hormonal balance more effectively than standard zinc forms
  • Four tocopherol forms of vitamin E provide the complete antioxidant spectrum — gamma and delta tocopherols, often absent from standard multivitamins, contribute the majority of vitamin E's anti-inflammatory and cell-protective activity
  • Three forms of selenium ensure broad metabolic coverage — selenite for rapid availability, high-selenium yeast for sustained release, and Se-methyl L-selenocysteine for targeted antioxidant and immune support
  • B vitamins and magnesium contribute to normal energy-yielding metabolism and the reduction of tiredness and fatigue
  • Vitamin C, zinc, and selenium contribute to the normal function of the immune system
  • Vitamin D3 and magnesium contribute to the maintenance of normal bones and normal muscle function

about this product.

Over 25 essential nutrients in a single daily tablet — featuring bioavailable forms most multivitamins skip, including 5-MTHF folate, methylcobalamin B12, L-OptiZinc, all four forms of vitamin E, and three forms of selenium — from the brand that has spent 40+ years advancing nutritional science.

Most people take a multivitamin and assume the job is done. The reality is that the majority of high-street multivitamins use the cheapest, least absorbable forms of every nutrient — folic acid instead of methylfolate, cyanocobalamin instead of methylcobalamin, zinc oxide instead of chelated zinc, dl-alpha tocopherol instead of the full vitamin E spectrum. These synthetic or poorly bioavailable forms look adequate on the label but deliver a fraction of their stated value to your cells. You swallow a tablet every morning, trust that it is working, and your body excretes most of what it cannot absorb. The multivitamin market is built on the assumption that consumers will never check the forms on the back of the bottle — and for decades, that assumption has held.

The consequences of cheap formulation are not dramatic enough to notice on any single day, but they compound over years. Suboptimal B vitamin intake contributes to fatigue, poor methylation, and elevated homocysteine. Insufficient zinc in a poorly absorbed form leaves immune function, skin integrity, and hormonal balance unsupported. A single form of vitamin E misses the gamma, delta, and beta tocopherols that provide the majority of vitamin E's antioxidant and anti-inflammatory activity. Folic acid — the synthetic form — requires enzymatic conversion that approximately 40% of the population performs inefficiently due to MTHFR gene variants, meaning nearly half of all multivitamin users may be getting negligible folate benefit from their daily tablet. You pay for 25 nutrients. Your body receives a fraction.

Life Extension One-Per-Day was formulated to eliminate this gap. Every nutrient form was selected for bioavailability and clinical relevance. 5-MTHF (5-methyltetrahydrofolate calcium salt) is the biologically active form of folate — no conversion required, effective regardless of MTHFR status. Methylcobalamin is the active, coenzyme form of B12 that your nervous system uses directly. L-OptiZinc (zinc mono-L-methionine sulphate) is a patented chelated zinc with superior absorption and retention compared to standard zinc oxide or gluconate. All four forms of vitamin E — alpha, beta, gamma, and delta tocopherols — provide the full spectrum of antioxidant protection rather than the isolated alpha-tocopherol that most multivitamins rely on.

Three forms of selenium — sodium selenite, SelenoExcell high-selenium yeast, and Se-methyl L-selenocysteine — provide broad-spectrum selenium activity across multiple metabolic pathways. Vitamin D3 at 2000 IU supports immune function, bone health, and mood. Alpha-lipoic acid, lycopene, quercetin, and marigold extract round out the formula with targeted antioxidant and phytonutrient support.

Life Extension has been at the forefront of preventative nutritional science for over 40 years, backed by a team of physicians, researchers, and nutritional scientists. Over 400 products across 40+ health categories. Soy-free, gluten-free, non-GMO. 60 tablets per bottle — a two-month supply at one tablet daily.

People who read the back of the bottle before they buy understand that a multivitamin is only as effective as the forms it uses. Choosing bioavailable, clinically selected nutrient forms reflects a refusal to pay for a label while your body receives a fraction.

You gain methylation support, which removes the bottleneck created by synthetic folic acid in MTHFR variant carriers and enables efficient folate metabolism through the biologically active 5-MTHF form

You gain full-spectrum antioxidant protection, which removes the incomplete coverage of single-form vitamin E and isolated selenium and enables broad defence across four tocopherols and three selenium compounds

You gain immune foundation, which removes the gaps left by poorly absorbed zinc, vitamin C, and selenium forms and enables consistent daily support through patented L-OptiZinc, ascorbate-complex vitamin C, and triple-source selenium

You gain energy and fatigue reduction, which removes the dragging tiredness associated with suboptimal B vitamin and magnesium intake and enables sustained energy production through bioavailable cofactors your metabolism depends on

You gain bone and mood support, which removes the deficiency risk created by inadequate vitamin D3 and magnesium and enables maintained skeletal density and emotional equilibrium — particularly through darker months

how to take it

i.

Take one tablet daily with a meal for optimal absorption of fat-soluble vitamins A, D, E, and K. Morning is ideal for the energy-supporting B vitamins. Do not exceed the recommended dose. Individuals consuming more than 50 mcg (2000 IU) of vitamin D daily from combined diet and supplements should periodically obtain a serum 25-hydroxyvitamin D measurement. Not recommended for individuals with high blood calcium levels. Consult your healthcare professional before use if pregnant, breastfeeding, taking medications, or undergoing treatment for a medical condition. Store in a cool, dry place out of reach of children. 60 tablets — two-month supply.

ii.

The multivitamin for people who actually read the label — because the forms on the back matter more than the claims on the front.

frequently asked.

Do I need to take this with food?

Yes — taking it with a meal is advisable. Fat-soluble vitamins (A, D, E and K) are better absorbed alongside dietary fat, and taking any multivitamin with food also reduces the chance of nausea.

Can this replace individual supplements I already take?

It depends on your specific needs. A broad multivitamin covers common micronutrients at general support levels, but if you have a confirmed deficiency — low ferritin, vitamin D insufficiency, for example — you are likely to need a targeted standalone supplement at a therapeutic dose alongside it.

Is this suitable for vegetarians or vegans?

Check the packaging for capsule composition and ingredient sourcing, as this detail is not confirmed in the product information we hold. Life Extension does produce vegetarian-friendly products, but we cannot confirm this specific SKU without the label.

How long before I notice a difference?

Multivitamins are not designed for acute, noticeable effects. Their value lies in maintaining adequate micronutrient status over time. If you are addressing a specific deficiency, a follow-up blood test after 8–12 weeks is the most reliable way to assess impact.

Can I take this alongside other Life Extension supplements?

Generally yes, but be mindful of overlap — combining a multivitamin with individual vitamin D, vitamin A, or iron supplements can push certain nutrients above advisable levels. Review your full supplement stack with a clinician if you are unsure.
