Walk the shelf and you’ll find a lot of single-form magnesiums — often magnesium oxide, the cheapest source — bulked out with fillers to look like a full capsule.
Different magnesium forms have different absorption profiles. A multi-form complex covers more of that spectrum than any single form on its own. Ours is simple: 1,000mg of magnesium complex, eight forms, every mg disclosed.
Magnesium is the second-most-abundant intracellular cation in the human body and a cofactor in hundreds of enzymatic reactions. Different forms have different absorption profiles. Here is how this one is built.
An essential dietary mineral, supplied across eight forms. Each form contributes to a 1,000mg total complex with every milligram disclosed — no proprietary blends and honest framing on what the evidence supports.

Before a single pouch ships, every batch is sent to an independent ISO/IEC 17025-accredited laboratory. Identity of the magnesium forms confirmed, dose verified, contaminants screened. If it fails any specification, it does not ship.
No proprietary blend, no bulking agents, no fillers. Eight named forms of magnesium summing to 1,000mg per serving — every milligram printed on the label.
The formula combines eight forms of magnesium — bisglycinate, citrate, malate, L-threonate, taurate, orotate, aspartate and carbonate — summing to 1,000mg of total complex per 2-capsule serving. That provides 375mg of elemental magnesium, 100% of the UK NRV.
This is a food supplement. Magnesium carries authorised nutrient claims under the EU/UK health-claims register: it contributes to normal muscle function, normal functioning of the nervous system, and the reduction of tiredness and fatigue. It can be taken alongside our NMN + Trans-Resveratrol as part of a wider routine.

We would rather be honest than make a sale. Here is who this product is for and who it is not for.
The market is full of single-form magnesiums — often oxide, padded with bulking agents — or proprietary blends that hide the per-form doses. Here is how this one is built by comparison.
| Feature | Vitality Ultimate 8 | Typical retail brand |
|---|---|---|
| Number of magnesium forms | 8 | Usually 1 |
| Bisglycinate included | ✓ Yes | Often missing |
| L-threonate included | ✓ Yes | Rare |
| Per-form doses disclosed | ✓ Every mg on label | Often proprietary blend |
| Elemental Mg per serving | 375mg / 100% NRV | Often under 100mg |
| Fillers / bulking agents | ✓ None | Common |
| Third-party tested | ✓ Every batch · ISO 17025 | Rarely disclosed |

Two capsules daily with water, ideally with food. Many people prefer evenings since some magnesium forms are commonly associated with relaxation. No cycling required. If you take prescription medication, are due for surgery, or are pregnant or breastfeeding, consult your doctor first.
Bisglycinate, citrate, malate, threonate and the rest, all with their doses disclosed. No proprietary blend hiding the numbers. This is the magnesium I was looking for.
Came over from a cheap oxide capsule. Two of these a day, no stomach issues, and the label tells me exactly which forms I’m taking. Easy reorder.
Emailed asking for the Certificate of Analysis and it came back the same day, batch number matching my pouch. Clean ingredient list, sensible per-day cost on the 3-pack.
Ultimate 8 Magnesium is a single-product complex containing eight forms of magnesium — bisglycinate, citrate, malate, L-threonate, taurate, orotate, aspartate and carbonate — totalling 1,000mg of magnesium complex per 2-capsule serving, with every form printed on the label.
Different magnesium forms have different absorption profiles and have been studied in different contexts. A multi-form complex covers more of that spectrum than any single form on its own. We list each form and its amount on the label so there is no proprietary blend.
Each 2-capsule serving provides 1,000mg of total magnesium complex, delivering 375mg of elemental magnesium — 100% of the UK Nutrient Reference Value (NRV).
Magnesium is an authorised nutrient under the EU/UK health-claims register. At sufficient intake, magnesium contributes to normal muscle function, normal functioning of the nervous system, and the reduction of tiredness and fatigue, among other functions.
As a food supplement, adults take 2 capsules daily with water, ideally with food. Do not exceed the stated recommended daily dose. If you take prescription medication, are due for surgery, or are pregnant or breastfeeding, consult your doctor first.
Yes. Every batch is tested at an independent ISO/IEC 17025-accredited laboratory before release. The Certificate of Analysis confirms identity of the magnesium forms, dose, heavy metals and microbial safety. A CoA is available on request — email us with your batch number.
The capsule shell is vegetarian HPMC and the product is gluten-free, dairy-free, soy-free and free from GMOs and artificial colours. Suitable for vegetarians; suitable for vegans subject to capsule shell tolerance.
Most people take magnesium in the evening because some forms are associated with relaxation, but morning or split dosing with food is fine. The most important thing is taking it consistently each day.
Some single-form magnesiums (notably oxide and high-dose citrate) are known for laxative effects. This complex leans on better-tolerated chelated forms such as bisglycinate, alongside citrate, malate and others — so most people find it well tolerated. Start with one capsule if you are sensitive.
Many retail magnesium capsules are a single form (often oxide or citrate) and may rely on fillers to bulk the capsule. This product is built differently: eight forms covering different absorption profiles, with every milligram disclosed and no proprietary blends.
It is commonly taken as part of a wider longevity stack and has no known issue when combined with supplements such as our NMN + Trans-Resveratrol or AHCC. If you take prescription medication, speak to your doctor before combining supplements.
We offer a 60-day money-back guarantee, no questions asked. If you're not satisfied for any reason, contact our customer support team within 60 days of purchase for a full refund.
