Drug Class: Magnesium + Vitamin D3 Nutritional Supplement | Form: Oral Capsule | Pack Size: 60 Capsules | Prescription Status: Available Without Prescription (OTC) — Fablous Pharma, Lahore
What is Fablous Flexoua-D Capsule?
Fablous Flexoua-D is a premium high-absorption magnesium supplement combining Magnesium Glycinate 500mg complex — providing approximately 50mg elemental Magnesium in its most bioavailable amino acid chelate form — with Vitamin D3 1000 IU (Cholecalciferol) in a single daily capsule. Unlike inorganic magnesium forms such as Magnesium Oxide or Magnesium Sulphate that are poorly absorbed and commonly cause diarrhoea, Magnesium Glycinate is chelated to the amino acid Glycine — producing superior gastrointestinal tolerability and significantly higher cellular absorption. The addition of Vitamin D3 is clinically rational — Vitamin D3 regulates magnesium transport and activation, and magnesium is essential for converting Vitamin D3 into its active form. These two nutrients are genuinely interdependent — each enhancing the other's effectiveness. Flexoua-D is specifically formulated for muscle relaxation, nerve function, sleep quality improvement, bone density support, and cardiovascular health — addressing the multiple physiological roles where magnesium deficiency most commonly causes symptoms in Pakistani adults.
What is Fablous Flexoua-D Used For?
- Muscle cramps and spasms — magnesium is essential for muscle relaxation after contraction (پٹھوں کی اینٹھن اور کھنچاؤ میں کمی)
- Sleep quality improvement — Magnesium Glycinate's calming effect supports deeper and more restorative sleep (نیند کی بہتری)
- Post-workout muscle soreness — reducing exercise-induced muscle damage and accelerating recovery (ورزش کے بعد تھکاوٹ اور درد میں کمی)
- Nerve function support — magnesium regulates neuronal excitability and neuromuscular transmission (اعصابی صحت)
- Bone density support — Vitamin D3 and Magnesium together support calcium absorption and skeletal mineralisation (ہڈیوں کی مضبوطی)
- Cardiovascular health — magnesium supports healthy blood pressure and cardiac rhythm (دل اور خون کی نالیوں کی صحت)
- Stress and anxiety reduction — Magnesium Glycinate's Glycine component has calming neurological effects (ذہنی تناؤ میں کمی)
- Magnesium deficiency correction — addressing dietary magnesium insufficiency common in Pakistani diet
How Does it Work?
Magnesium Glycinate provides elemental Magnesium bound to two Glycine molecules — this chelated form is recognised by intestinal amino acid transporters rather than relying on passive diffusion like inorganic magnesium salts, producing absorption rates substantially higher than Magnesium Oxide or Magnesium Sulphate. Once absorbed, Magnesium acts as a cofactor in over 300 enzymatic reactions — critically regulating muscle contraction and relaxation by competing with Calcium at actin-myosin binding sites, stabilising neuronal membranes by blocking NMDA glutamate receptors to reduce neuronal hyperexcitability, activating ATP energy molecules, and supporting normal cardiac rhythm through regulation of potassium and calcium channels. Glycine — the amino acid carrier — additionally provides independent calming neurological benefits by acting as an inhibitory neurotransmitter in the spinal cord and brainstem, contributing to Magnesium Glycinate's superior sleep-promoting effect compared to other magnesium forms. Vitamin D3 1000 IU activates Vitamin D receptors in the intestine to increase calcium and magnesium absorption — while Magnesium reciprocally converts inactive Vitamin D3 into its biologically active form calcitriol — creating genuine bidirectional synergy between these two nutrients.
Dosage and Administration
⚠️ Take with or after a meal to improve tolerability. Taking before bedtime maximises sleep quality benefit from Magnesium Glycinate's calming effect. Do not exceed one capsule daily without medical advice. Magnesium Glycinate is significantly gentler than other magnesium forms but high doses can still cause loose stools in sensitive individuals.
| Indication | Usual Adult Dose | Frequency | Best Timing |
|---|---|---|---|
| Muscle cramps / Spasms | 1 capsule | Once daily | With evening meal or before bed |
| Sleep quality improvement | 1 capsule | Once daily | 30 to 60 minutes before bedtime |
| Post-workout recovery | 1 capsule | Once daily | After workout with meal |
| Bone and cardiovascular support | 1 capsule | Once daily | With any main meal |
| Magnesium deficiency | 1 capsule | Once daily | With food — consistent timing |
Active Ingredients
| Ingredient | Strength per Capsule | Primary Role |
|---|---|---|
| Magnesium Glycinate Complex | 500mg (approx. 50mg elemental Magnesium) | Muscle relaxation, nerve function, sleep, cardiovascular health |
| Vitamin D3 (Cholecalciferol) | 1000 IU | Calcium and magnesium absorption, bone mineralisation, immune function |
Who Should NOT Take Fablous Flexoua-D?
- Allergy to any component of the capsule including gelatin if applicable
- Severe kidney impairment — kidneys regulate magnesium excretion; accumulation risk in renal failure; consult nephrologist before use
- Hypermagnasaemia — already elevated blood magnesium levels
- Hypercalcaemia — Vitamin D3 increases calcium absorption; may worsen elevated calcium
- Hypervitaminosis D — existing Vitamin D toxicity; do not combine with other high-dose Vitamin D supplements without medical monitoring
- Myasthenia gravis — magnesium reduces neuromuscular transmission; may worsen symptoms
- Heart block — high magnesium doses can slow cardiac conduction
- Children under 12 years — adult formulation; consult paediatrician
- Pregnancy — consult obstetrician before use; magnesium supplementation in pregnancy requires medical supervision
Side Effects
Magnesium Glycinate is the best-tolerated magnesium form — significantly gentler on the gastrointestinal tract than other magnesium salts at equivalent doses.
Common Side Effects:
Mild loose stools or mild diarrhoea at higher doses — substantially less common than with Magnesium Oxide or Sulphate (پتلے دست — Magnesium Glycinate میں بہت کم ہوتے ہیں), mild stomach discomfort if taken on completely empty stomach — take with food (کھانے کے ساتھ لینے سے کم ہوتی ہے), mild drowsiness — beneficial when taking before bed but avoid driving if taken during the day (ہلکی نیند آنا).
Serious Side Effects:
Seek medical attention immediately: Signs of magnesium toxicity from excessive intake — severe nausea, profound muscle weakness, extremely low blood pressure, breathing difficulty, and irregular heartbeat (فوری ہسپتال جائیں — خوراک سے زیادہ نہ لیں), signs of Vitamin D toxicity with prolonged use alongside other D supplements — excessive thirst, frequent urination, confusion, and kidney pain (فوری ڈاکٹر کو بتائیں), severe allergic reaction — sudden widespread rash, swelling of face or throat (فوری مدد لیں), significant worsening of kidney function in patients with pre-existing renal impairment (فوری ڈاکٹر کو بتائیں).
Drug Interactions
| Medicine | Interaction |
|---|---|
| Antibiotics (Tetracyclines, Fluoroquinolones) | Magnesium significantly reduces antibiotic absorption — take Flexoua-D at least 2 hours apart from any antibiotic course |
| Bisphosphonates (Alendronate, Risedronate) | Magnesium reduces bisphosphonate absorption — take at least 2 hours apart |
| Levothyroxine (thyroid medicine) | Magnesium reduces Levothyroxine absorption — take at least 4 hours apart |

Frequently Asked Questions (FAQs)
Q: Why is Magnesium Glycinate better than regular Magnesium Oxide for muscle cramps and sleep?
Magnesium Oxide is only approximately 4% absorbed — most of it passes through the gastrointestinal tract causing diarrhoea without reaching muscle and nerve tissue. Magnesium Glycinate is absorbed through amino acid transporters with significantly higher bioavailability — delivering more elemental Magnesium to muscles, nerves, and brain cells where it exerts its therapeutic effects. The Glycine component additionally provides independent calming neurological benefits — making Magnesium Glycinate the superior form specifically for sleep quality and muscle relaxation compared to all other magnesium forms.
Q: Why does Flexoua-D combine Vitamin D3 with Magnesium Glycinate — what is the benefit of this specific combination?
The combination is genuinely synergistic rather than merely convenient. Magnesium is an essential cofactor for the enzymatic conversion of inactive Vitamin D3 into its biologically active form calcitriol — without adequate magnesium, supplemental Vitamin D3 cannot be properly activated regardless of dose. Conversely Vitamin D3 upregulates intestinal magnesium absorption transporters — improving magnesium bioavailability. Each nutrient is required for the other to function optimally — making their combination in Flexoua-D clinically more effective than taking either supplement separately.
Q: Is it safe to take Flexoua-D alongside other supplements containing Vitamin D3?
Caution is required — Vitamin D3 is a fat-soluble vitamin that accumulates in body fat and can reach toxic levels with excessive combined intake. The total daily Vitamin D3 from all sources — Flexoua-D plus any other multivitamin, prenatal supplement, or standalone Vitamin D supplement — should not regularly exceed 4000 IU without medical monitoring of blood Vitamin D levels. Always inform your doctor of all supplements you are taking and consider periodic Vitamin D blood level testing if using multiple Vitamin D-containing products simultaneously.
