Your Personal Plan, Fairly Priced
Transparent, volume-based pricing that rewards you for building a complete plan.
Most supplement companies charge the same per product whether you buy one or ten. We think that's unfair — packaging, shipping, and handling costs are shared across your entire order.
How it works: The more products in your personalized plan, the lower the cost of each one. Shared costs like daily pouches, your dispenser box, and shipping are split across everything in your box.
No hidden fees. No inflated single-product pricing to make bundles look like deals. Just honest math.
How does this look in practice?
Packaging costs like your biodegradable pouches, dispenser box, and shipping are split across all products. Fewer products = higher cost each. More products = lower cost each. Simple.
We stand by our science — enjoy 90 days risk-free. Read more

Understanding Bioavailability
Why the form of a vitamin matters as much as the vitamin itself
The Restaurant Example
Imagine ordering salmon at a restaurant. The menu says "salmon", but what arrives could be perfectly grilled, raw, or still wrapped in plastic. Technically all salmon, but only one is actually nourishing.
Vitamins work the same way. A label might say "Vitamin C 1000 mg," but that vitamin could be in a form your body barely absorbs, or one it uses efficiently. The form determines whether your body can actually use what you're taking.
What Is Bioavailability?
Bioavailability is the amount of a nutrient that actually enters your bloodstream and reaches your cells.
If you take 100 mg of a vitamin but only 20 mg gets absorbed, the bioavailability is 20%. The rest passes through unused.
What affects bioavailability:
- The chemical form of the vitamin
- Your individual gut health and genetics
- What you eat alongside the supplement
Common Vitamin Forms Explained
Methylated Vitamins (Active Forms)
Some people struggle to convert standard vitamins into their active, usable forms due to genetic variations. Methylated vitamins skip that step; they're already active.
Example: Methylcobalamin (B12) vs Cyanocobalamin
- Methylcobalamin Active form, immediately usable
- Cyanocobalamin Synthetic, requires conversion (which 40-60% of people struggle with due to MTHFR gene variants)
Common forms: Methylfolate (5-MTHF), methylcobalamin (B12), P-5-P (B6)
Natural vs Synthetic
"Natural" doesn't automatically mean better; it depends on the specific vitamin.
Example: Vitamin E
- Natural (d-alpha-tocopherol): Derived from plants, more biologically active
- Synthetic (dl-alpha-tocopherol): Contains 8 forms, only one your body prefers
Example: Vitamin C
- Ascorbic acid (synthetic) is molecularly identical to natural vitamin C and equally effective
- Liposomal vitamin C: Wrapped in fat bubbles for enhanced absorption and higher blood levels
Fat-Soluble vs Water-Soluble
Fat-soluble vitamins (A, D, E, K) need fat to be absorbed. Taking them with food containing healthy fats significantly improves uptake.
Water-soluble vitamins (B, C) dissolve in water and are absorbed more easily, but excess is excreted quickly, making sustained-release forms sometimes beneficial.
What "Bioavailable" Actually Means on a Label
When we say "bioavailable form," we mean:
- Active forms that don't require conversion (methylated B vitamins)
- Forms with proven absorption backed by scientific research
- Enhanced delivery systems (like liposomal technology)
What it shouldn't mean: vague marketing language without specifics.
Red flags to watch for:
- No specific form listed (just "Vitamin B12" without the type)
- "Proprietary blends" that hide ingredient amounts
- Claims without any absorption data
The Bottom Line
A cheaper supplement with poor bioavailability isn't a bargain. The best supplements aren't about taking more; they're about absorbing what you take.
What to look for:
- Specific forms clearly listed on the label
- Science-backed forms (methylated, chelated, liposomal)
- Transparency about dosages and sources
At Persona, we choose forms based on scientific evidence for absorption, not what's cheapest to manufacture. Because if your body can't use it, what's the point?

- Supports immune function, skin, hair, and nails (EFSA approved)
- Good bioavailability at an accessible price point
- See our main Zinc page for detailed research and EFSA claims
Biochemistry Timeline
Zinc citrate is well-absorbed and benefits can begin within 2-4 weeks for immune and skin health. See our main Zinc page for detailed biochemistry and timelines.
Summary
Zinc Citrate is a well-absorbed form of zinc supporting immune, skin, hair, and hormonal health. See our main Zinc page for comprehensive research, EFSA claims, and detailed information.
FAQs
How does zinc citrate compare to other zinc forms?
Zinc citrate offers good bioavailability and is generally well-tolerated. It tends to cause less digestive discomfort than zinc sulphate, making it a popular choice for supplementation.
Can zinc interfere with copper absorption?
Yes, high doses of zinc taken over extended periods can reduce copper absorption. If you take zinc supplements long-term, ensuring adequate copper intake is important.
When is the best time to take zinc?
Zinc is best taken with food to reduce the chance of stomach discomfort. Avoid taking it at the same time as high-fibre meals or calcium supplements, as these can reduce absorption.

The Benefits of Vitamin C
Antioxidant
Vitamin C is a powerful antioxidant essential for immune function, collagen formation, and the protection of cells from oxidative stress. We use vitamin C derived from acerola cherry, a whole-food source that provides naturally occurring bioflavonoids alongside the vitamin C, which may support better absorption compared to synthetic ascorbic acid.
Key Highlights
- Contributes to the normal function of the immune system (EFSA approved)
- Supports normal collagen formation for skin, blood vessels, bones, cartilage, gums, and teeth (EFSA approved)
- Contributes to the protection of cells from oxidative stress (EFSA approved)
- Increases iron absorption (EFSA approved)
- Contributes to the reduction of tiredness and fatigue (EFSA approved)
- Supports normal energy-yielding metabolism (EFSA approved)
- Derived from acerola cherry for enhanced bioavailability
Biochemistry Timeline
Vitamin C is water-soluble, meaning the body does not store it and relies on regular daily intake. Blood levels can improve within days of starting supplementation, and immune function benefits are generally seen with consistent daily intake of 200 mg or more.
For collagen-related benefits (skin firmness, wound healing), consistent supplementation over 8 to 12 weeks is typically needed to see visible improvements, as collagen turnover in the skin is a gradual process.
Energy and Fatigue
Vitamin C contributes to normal energy-yielding metabolism and to the reduction of tiredness and fatigue, both EFSA-approved health claims. It plays a role in the metabolism of fats and the production of carnitine, a molecule that helps transport fatty acids into mitochondria for energy production.
For those experiencing persistent fatigue, ensuring adequate vitamin C intake supports the body's ability to produce energy efficiently. This is particularly relevant for smokers, who have 25% lower plasma vitamin C levels and are recommended to consume an additional 35 mg/day (IOM recommendation).
Antioxidant Protection
Vitamin C is one of the body's primary water-soluble antioxidants. It neutralises free radicals, protects cellular components from oxidative damage, and helps regenerate other antioxidants, including vitamin E.
This antioxidant function is important for overall health, as oxidative stress is implicated in ageing, cardiovascular disease, and various chronic conditions. By choosing acerola cherry as our source, the naturally occurring bioflavonoids and plant compounds provide additional antioxidant support beyond vitamin C alone. EFSA recognises that vitamin C contributes to the protection of cells from oxidative stress.
Summary
Vitamin C is an essential antioxidant that supports immune function, collagen formation, iron absorption, and energy production. We use acerola cherry as a whole-food source, providing naturally occurring bioflavonoids for potentially enhanced absorption. Regular supplementation reduces cold duration and supports the body's daily needs.
As a water-soluble vitamin, consistent daily intake is important since the body does not store vitamin C. It is particularly relevant for those with higher needs, including smokers, women with iron absorption concerns, and anyone seeking to support skin health and immune resilience.
FAQs
Why acerola cherry instead of synthetic vitamin C?
Acerola cherry is one of nature's richest sources of vitamin C and provides it alongside bioflavonoids and other plant compounds that may enhance absorption and provide additional antioxidant benefits. It represents a whole-food approach to vitamin C supplementation.
How much vitamin C do I need daily?
The recommended daily intake for adults in the EU is 80 mg. For immune support during and after exercise, EFSA recognises benefits at 200 mg/day. The European upper limit is 1,000 mg/day from supplements. Most people benefit from 200-500 mg/day.
Can I take too much vitamin C?
Because vitamin C is water-soluble, excess amounts are excreted in urine. However, very high doses (above 1,000 mg/day) can cause digestive discomfort in some people and may increase the risk of kidney stones in susceptible individuals.
Does vitamin C really prevent colds?
Research shows that regular vitamin C supplementation does not prevent colds in the general population but does reduce their duration (by about 8% in adults) and severity. The benefit is more pronounced in those under physical stress.
Is vitamin C safe during pregnancy?
Yes, vitamin C is important during pregnancy for both mother and baby. It supports iron absorption, immune function, and collagen formation. Follow your healthcare provider's guidance on dosage.
