Olimp ZMA (90 Caps)

🌙 The original ZMA® bedtime formula — not a generic copy

ZMA® is a registered trademark of SNAC System, Inc., and Olimp is a licensed manufacturer of the original certified formula. This distinguishes Olimp ZMA® from the many generic zinc-magnesium-B6 supplements on the market that replicate the ingredient list without the certified ZMA® formulation. For athletes and consumers who specifically seek the original ZMA® formula with verified ingredient ratios and sources, the Olimp ZMA® with its registered ZMA® trademark is the authentic choice.

🔬 L-OptiZinc® — patented zinc for superior bioavailability

The primary zinc source in Olimp ZMA® is L-OptiZinc® — a zinc mono-L-methionine complex produced under a patented process (InterHealth N.I., patent pending). Zinc is bonded to the amino acid L-methionine in a form that has demonstrated superior intestinal absorption compared to inorganic zinc sources (zinc oxide, zinc gluconate) in comparative bioavailability studies. At 10mg per 3-capsule dose (100% of the EU NRV), Olimp ZMA® provides a complete daily zinc contribution in its most bioavailable form.

⚗️ Zinc — normal testosterone levels and immune function

Zinc carries the EU-authorised health claim for contributing to the maintenance of normal testosterone levels in the blood — the primary reason ZMA® has been used by athletes since its development. Zinc is also EU-authorised for contributing to normal protein synthesis (directly relevant to muscle repair and growth), normal immune system function and the protection of cells from oxidative stress. Athletes training at high volume frequently lose zinc through sweat, making supplementation particularly relevant.

🔋 Magnesium — muscle function, energy metabolism and fatigue reduction

Magnesium is provided at 150mg per 3-capsule dose (40% of the EU NRV) from multiple complementary sources including L-aspartate, citrate and oxide — each with slightly different absorption characteristics. Magnesium carries EU-authorised health claims for contributing to normal muscle function, normal energy-yielding metabolism and the reduction of tiredness and fatigue. For athletes with high training volumes, magnesium losses through sweat are significant and daily supplementation is recommended.

💊 Vitamin B6 (250% NRV) — protein metabolism and nervous system support

Vitamin B6 (pyridoxine HCl) at 3.5mg per 3-capsule dose provides 250% of the EU NRV — a dose above the daily reference value that reflects both the increased metabolic demand of active individuals and the role B6 plays in the ZMA® matrix as a bioavailability enhancer for zinc and magnesium absorption. B6 carries EU-authorised health claims for normal protein and glycogen metabolism, normal functioning of the nervous system and the reduction of tiredness and fatigue.

😴 Bedtime formula — aligned with overnight hormonal activity

The bedtime consumption protocol is not a marketing choice — it is biochemically grounded. Natural testosterone and growth hormone secretion peaks during deep sleep (stages 3 and 4 of the sleep cycle). Providing zinc and magnesium 30 to 60 minutes before sleep ensures these minerals are available during the body's peak hormonal activity window. Magnesium also supports the nervous system's transition to rest, contributing to sleep quality alongside its performance recovery benefits.

🎯 Goal guide

🏋️ Mass gain: 3 capsules/day before sleep. Zinc supports normal testosterone levels and protein synthesis; magnesium supports muscle function and energy metabolism during high-volume training.

🔥 Weight loss / cutting: 3 capsules/day. Maintains hormonal environment and mineral status during caloric restriction, when dietary zinc and magnesium intake may be reduced.

⚖️ Daily wellbeing: 1 to 3 capsules/day. Zinc, magnesium and B6 as a complete overnight mineral support routine.

Serving suggestion

Take 1 capsule per day (maintenance protocol) or up to 3 capsules per day (athletic protocol), 30 to 60 minutes before sleep, with a large glass of water. Olimp recommends taking ZMA® on an empty stomach or at least 2 hours after the last meal for optimal absorption — dietary calcium (from dairy products) can compete with zinc and magnesium for intestinal absorption and reduce their bioavailability. Do not exceed the recommended daily dose. Not recommended for children, pregnant or breastfeeding women.

Best times to take it

🌙 30 to 60 minutes before sleep (primary recommendation)

The definitive timing for ZMA® — 30 to 60 minutes before sleep allows zinc and magnesium to be absorbed and available during the deep sleep stages when natural testosterone and growth hormone secretion peaks. This is the protocol used in the original ZMA® research and is the standard recommendation across all licensed ZMA® products.

🍽️ On an empty stomach or 2+ hours after the last meal

Calcium-rich foods (dairy, calcium-fortified foods) compete with zinc and magnesium for the same intestinal absorption pathway. Consuming ZMA® on an empty stomach or at least 2 hours after a meal — and separately from any calcium supplement — maximises the bioavailability of both minerals.

📅 Every day — including rest days

Zinc and magnesium status is maintained through consistent daily intake. Skipping rest days creates gaps in mineral availability that reduce the cumulative benefit. The bedtime protocol means ZMA® integrates naturally into a nightly routine regardless of training schedule.

Q1 — What is ZMA® and why does the registered trademark matter?

ZMA® is a specific combination of zinc (as zinc mono-L-methionine), magnesium and vitamin B6, originally developed by sports scientist Victor Conte and registered as a trademark by SNAC System, Inc. The trademark matters because many generic "ZMA" products on the market use cheaper zinc sources (zinc oxide, zinc gluconate) and different ratios — and call themselves ZMA without the certified formula. Olimp ZMA® uses the certified ZMA® formula with L-OptiZinc® as its zinc source, making it an authentic licensed product rather than a generic imitation.

Q2 — What is L-OptiZinc® and why is it superior to generic zinc?

L-OptiZinc® is a patented zinc mono-L-methionine complex produced under a patented process by InterHealth N.I. Zinc is bonded to the amino acid L-methionine — an organic chelation that protects the zinc from binding to phytates, oxalates and other dietary inhibitors in the digestive tract, and facilitates its transport across the intestinal wall. Comparative studies have demonstrated that zinc methionine achieves higher plasma zinc concentrations from equivalent oral doses than inorganic zinc forms (zinc oxide, zinc gluconate, zinc sulfate). For athletes who want to ensure their ZMA supplementation actually delivers the zinc dose to circulation, the L-OptiZinc® source is the meaningful quality choice.

Q3 — Why should ZMA® be taken before sleep and not before training?

The bedtime protocol is designed to align zinc and magnesium availability with the body's peak hormonal activity window — the deep sleep stages (NREM stages 3 and 4) when natural secretion of testosterone and growth hormone is at its highest. Taking ZMA® before training would still deliver the mineral dose but would miss the hormonal synergy of the overnight protocol. Additionally, magnesium supports the nervous system's transition to a rest state, which contributes positively to sleep onset — a secondary benefit that disappears if consumed earlier in the day.

Q4 — Why should ZMA® not be taken with dairy products or calcium supplements?

Zinc and magnesium compete with calcium for the same intestinal absorption transporters — specifically the divalent metal transporter 1 (DMT1) pathway. When high-calcium foods (dairy, calcium-fortified foods) or calcium supplements are consumed simultaneously, they reduce the absorption of both zinc and magnesium significantly. Consuming ZMA® on an empty stomach or at least 2 hours after the last meal, and separately from calcium supplements, ensures the mineral dose reaches circulation without being competitively excluded.

Q5 — Is the 90-capsule format the same formula as the previous 120-capsule format?

Yes. The formula is identical — the active ingredient profile per capsule (zinc, magnesium and vitamin B6 in the same doses and the same L-OptiZinc® source) is unchanged. Only the pack size has changed from 120 to 90 capsules. At the standard athletic protocol of 3 capsules per day, 90 capsules provides a 30-day supply.
