FerraVital Ingredients: What's Inside and Why Each One Matters
No proprietary blends. No hidden doses. No ingredients included for label decoration. Here's every ingredient in FerraVital, the exact form and dose we use, why it was chosen, and what the research says. If you want to know what you're putting in your body before you buy it, this is the page for that.
Why FerraVital Isn't Just Another Iron Supplement
Most iron supplements give you iron and stop there. FerraVital was designed around a different premise: ferritin restoration, not just iron supplementation. Getting iron into your bloodstream is step one. Getting it stored as ferritin — the form your body draws from for hair, energy, brain function, and temperature regulation — requires a supporting cast of cofactors that most formulas ignore.
Absorb
Iron bisglycinate + vitamin C for maximum uptake through dual pathways. Less wasted iron means fewer side effects.
Store
Lactoferrin + L-lysine to support ferritin storage specifically — not just circulating iron. This is what most formulas miss.
Utilize
B vitamins + minerals to turn stored iron into red blood cells, energy, neurotransmitters, and thyroid function.
Every ingredient below was selected to serve at least one of these three functions. Nothing is included for label padding.
Every Ingredient, Explained
The foundation of the formula. Iron bisglycinate is iron bonded to two glycine amino acid molecules. This chelation does three things: it absorbs through both standard (DMT-1) and peptide transporter pathways, it stays intact during digestion so less free iron irritates the gut, and it works even when taken with food — unlike ferrous sulfate, which requires an empty stomach.
45 mg provides meaningful repletion-level dosing without the GI side effects associated with the 65 mg ferrous sulfate tablets most doctors prescribe.
Ferrous sulfate absorbs at 10–15% and more than doubles GI side effects vs placebo (Tolkien et al., 2015). Most women quit within weeks. Iron bisglycinate absorbs comparably or better with significantly fewer side effects — meaning you actually take it long enough for your ferritin to recover.
Vitamin C enhances non-heme iron absorption by converting ferric iron (Fe³⁺) to ferrous iron (Fe²⁺) in the gut — the form your intestines can absorb. This is well-established science and the reason vitamin C is the most common iron cofactor.
What matters is the form. Most iron supplements use regular ascorbic acid, which is acidic and can irritate a stomach that's already sensitive from iron. Calcium ascorbate is a buffered, non-acidic form that provides the same absorption benefit without the acidity. For women who've had stomach problems with iron before, this distinction matters.
Research suggests that vitamin C doses of 25–100 mg meaningfully enhance iron absorption. 120 mg provides a strong absorption boost without the GI effects of high-dose vitamin C (500–1000 mg), which some supplements include unnecessarily.
An essential amino acid your body can't produce. Research by Dr. D. Hugh Rushton found that adding L-lysine to iron supplementation significantly improved ferritin levels in women who hadn't responded to iron alone. L-lysine appears to support intestinal iron absorption by helping solubilize iron in the gut and enhancing transport protein activity.
This is one of the two ingredients (alongside lactoferrin) that most iron supplements don't include — and that specifically target the women for whom iron alone wasn't enough.
Research studies used 1,500–2,000 mg daily as standalone supplementation. As a cofactor within a multi-ingredient iron formula, 400 mg provides meaningful support while keeping the capsule size practical for daily use.
A naturally occurring protein found in breast milk, tears, and saliva. In supplement form, lactoferrin has been shown to support iron absorption and storage by modulating hepcidin — the hormone that controls how much iron your body absorbs from food and supplements.
Every iron dose triggers a hepcidin spike that blocks further absorption. Lactoferrin may help keep that gate open longer, meaning more iron reaches your blood from each dose. It also provides an additional absorption pathway through lactoferrin receptors in the gut and has anti-inflammatory properties that support a healthier gut environment for iron absorption.
Most iron supplements contain zero lactoferrin because it's expensive to source and unfamiliar to mainstream supplement formulators. FerraVital includes it because the hepcidin mechanism addresses a real bottleneck that iron-only supplements ignore — especially for women whose ferritin is stubbornly low despite consistent iron intake.
Essential for red blood cell formation and DNA synthesis. When your body is rebuilding iron stores and producing new red blood cells, B12 demand increases. Deficiency of B12 alongside iron deficiency can cause a mixed anemia that's harder to resolve with iron alone.
Methylcobalamin is the active form of B12 — it's used directly by your body without needing conversion. Many supplements use cyanocobalamin, which must be converted to methylcobalamin before use. For women with MTHFR variants or methylation concerns, the active form is preferred.
Cyanocobalamin requires liver conversion. Methylcobalamin is biologically active immediately. When your body is already working overtime to rebuild iron stores, eliminating unnecessary metabolic steps means nutrients get used faster.
B6 is required for hemoglobin synthesis — the process of incorporating iron into the hemoglobin molecule inside red blood cells. Without adequate B6, your body can absorb iron but can't efficiently turn it into functional hemoglobin.
P5P is the bioactive form of B6. Like methylcobalamin, it works directly without liver conversion. Standard pyridoxine HCl requires conversion to P5P before use.
Folate works alongside B12 in red blood cell production and DNA synthesis. The active form L-5-MTHF is used directly by the body — critical for the estimated 30–40% of women with MTHFR gene variants who cannot efficiently convert synthetic folic acid to its usable form.
Folic acid is synthetic and requires multiple enzymatic conversion steps. Women with MTHFR variants may have impaired conversion, leading to inadequate folate status despite supplementation. L-5-MTHF bypasses this entirely.
Zinc supports hair follicle structure, immune function, and thyroid hormone synthesis. It's also involved in over 300 enzymatic reactions in the body. Many women with low ferritin are also zinc-deficient because the same dietary patterns and absorption challenges affect both minerals.
Zinc bisglycinate is chelated for better absorption and stomach tolerance — the same chelation logic as the iron form.
Zinc and copper compete for absorption. Supplementing zinc without copper over time can deplete copper levels, which impairs iron transport (copper is required for ceruloplasmin, the protein that mobilizes iron from storage). Including both prevents this imbalance.
Copper is required for ceruloplasmin — the protein that oxidizes iron so it can be loaded onto transferrin for transport through the bloodstream. Without adequate copper, iron can be absorbed and stored but not mobilized effectively. Copper deficiency can mimic iron deficiency on blood work.
1 mg is the standard supplemental dose that balances the 10 mg zinc without exceeding safe daily intake. Chelated as bisglycinate for absorption and tolerance.
Selenium serves two critical roles in this formula. First, it supports thyroid function — selenium is required for the deiodinase enzymes that convert T4 (inactive thyroid hormone) to T3 (active). For women with both thyroid conditions and low ferritin, selenium addresses both systems. Second, selenium is a powerful antioxidant that protects the thyroid gland from oxidative damage — particularly important in autoimmune thyroid disease.
L-selenomethionine is the organic, food-form selenium with the best absorption and tissue retention compared to selenite or selenate forms.
55 mcg is the recommended daily allowance (RDA) for adult women. This provides full daily selenium support without exceeding the level where side effects become possible (upper limit: 400 mcg). For women already getting some selenium from diet, this brings them to optimal without risk of excess.
What's NOT in FerraVital — and Why
What a formula excludes is as important as what it includes. Every absence below is a deliberate choice:
✕ Ferrous Sulfate
The cheapest iron form and the most likely to cause constipation, nausea, and cramping. We use iron bisglycinate instead — better absorbed, dramatically better tolerated.
✕ Ascorbic Acid
Regular vitamin C is acidic and can irritate sensitive stomachs. We use calcium ascorbate — same absorption benefit, no acidity.
✕ Folic Acid
Synthetic folate that requires conversion. We use L-5-MTHF — the active form that works directly, especially important for MTHFR carriers.
✕ Cyanocobalamin
Synthetic B12 requiring liver conversion. We use methylcobalamin — biologically active immediately.
✕ Gluten, Dairy, Soy, Eggs, Nuts
Common allergens excluded. The formula is designed to be tolerable for women with multiple sensitivities — gut health matters for iron absorption.
✕ Artificial Colors, Fillers, Flow Agents
Vegetable cellulose capsule. No titanium dioxide, magnesium stearate, or silicon dioxide. Nothing unnecessary.
