Quick Verdict: NOW Foods Magnesium Glycinate is one of the best budget magnesium supplements for sleep and relaxation. It uses Albion’s chelated magnesium bisglycinate for high absorption, comes in both tablet (180/240 count) and capsule with BioPerine versions, and costs as little as $0.08/day. If you want quality magnesium glycinate without paying premium prices, NOW Foods delivers.
Looking for a budget-friendly magnesium glycinate that actually works? In this NOW Foods Magnesium Glycinate review, I’ll break down what makes this supplement a top contender for adults over 40 who want better sleep, less stress, and fewer muscle cramps — without breaking the bank.
NOW Foods has been making supplements since 1968 and is one of the most trusted brands in the industry. Their magnesium glycinate line includes two versions: the classic tablets and a newer capsule formula with BioPerine for enhanced absorption. Let’s look at both.
The Two Versions: Tablets vs Capsules with BioPerine
NOW Foods offers two magnesium glycinate products:
NOW Magnesium Glycinate Tablets (180 or 240 count)
- 200mg elemental magnesium per serving (2 tablets)
- From Albion magnesium bisglycinate chelate
- No BioPerine
- Price: ~$10-15 per bottle (~$0.08-0.12/day)
NOW Magnesium Glycinate with BioPerine Capsules (60 count)
- 200mg elemental magnesium per serving (2 capsules)
- From magnesium bisglycinate chelate
- Includes BioPerine (black pepper extract) for enhanced absorption
- Price: ~$12-15 per bottle (~$0.40/day)
For most people on a budget, the tablet version is the better value. If absorption is your priority and you don’t mind paying more, the BioPerine capsule version is worth considering.
What I Like About NOW Foods Magnesium Glycinate
Incredibly affordable. The 240-tablet bottle is one of the cheapest quality magnesium glycinate supplements available. At around $0.08-0.12/day, you’re paying less for a month’s supply than most people spend on a single coffee.
Uses Albion chelated magnesium. The tablet version uses Albion’s magnesium bisglycinate — the same trusted chelation technology found in more expensive brands like Doctor’s Best. Albion is the gold standard in mineral chelation, with decades of research behind their process.
50+ years of brand trust. NOW Foods was founded in 1968 and is one of the largest independent, family-owned supplement manufacturers in the US. They have in-house laboratories with ISO/IEC accreditation, and their team of 150+ quality-control professionals performs over 10,000 lab tests per month.
GMP certified manufacturing. Every aspect of NOW’s manufacturing process is examined and certified. Their A-rated GMP certification means consistent quality batch after batch.
Gentle on the stomach. Glycinate form is known for being easy on digestion, and user reviews consistently confirm this. Unlike magnesium oxide or citrate, this form rarely causes digestive discomfort.
Flexible dosing. The 2-tablet serving gives you 200mg, but you can easily take 1 tablet for a lighter dose or 3-4 for a higher therapeutic dose. This flexibility is valuable for finding your personal sweet spot.
Vegan and allergen-free. Free from GMOs, wheat, gluten, soy, milk, egg, fish, shellfish, tree nuts, and sesame. Suitable for vegetarians and vegans.
BioPerine option available. If you want enhanced absorption, the capsule version with BioPerine (black pepper extract) is a nice upgrade. BioPerine has been shown to increase the bioavailability of various nutrients.
What Could Be Better
Tablets are large. This is the most common complaint across user reviews. The tablets are bigger than average. If you have difficulty swallowing large pills, the capsule version with BioPerine might be easier, though it’s significantly more expensive per day.
You need 2-4 tablets for a full dose. At 100mg of elemental magnesium per tablet, you need at least 2 tablets for a meaningful dose and 3-4 for the therapeutic range of 300-400mg. That’s a lot of pills to swallow, especially large ones.
No third-party certification logo on label. While NOW Foods conducts extensive in-house testing and has GMP certification, they don’t display independent certifications like NSF or USP on this specific product. Their overall manufacturing facility is well-certified, but product-specific third-party logos would add confidence.
The BioPerine version is expensive. At $0.40/day for only 60 capsules, the BioPerine version loses its budget advantage. At that price, you could buy Doctor’s Best for similar money with Albion TRAACS technology.
Standard chelation, not TRAACS. The tablet version uses Albion bisglycinate chelation, which is good. But Doctor’s Best uses Albion’s more advanced TRAACS (lysinate glycinate) chelation, which some studies suggest may absorb slightly better. The difference is small, but it exists.
How to Take NOW Foods Magnesium Glycinate
For sleep: Take 3-4 tablets (300-400mg) about 30-60 minutes before bed with a small snack.
For general health: Take 2 tablets (200mg) with breakfast or dinner as the label suggests.
For muscle cramps: Take 2 tablets after workouts and 2 before bed.
Start low: If you’re new to magnesium, begin with 1 tablet (100mg) daily for the first week and gradually increase. This helps your body adjust.
With food: Taking with food improves absorption and reduces any chance of stomach discomfort, though this form is gentle enough to take on an empty stomach for most people.
Consistency: Magnesium builds up in your system over days. Take it daily for best results. Most people notice sleep improvements within 3-7 days.
Who Should Take NOW Foods Magnesium Glycinate?
Great for:
- Budget-conscious buyers who want quality magnesium glycinate
- Adults over 40 dealing with poor sleep or muscle cramps
- People who want a trusted, established brand
- Those who prefer flexible dosing options
- Anyone looking for an allergen-free, vegan option
Not ideal for:
- People who struggle swallowing large tablets
- Those who want the highest possible absorption (consider Doctor’s Best TRAACS or the BioPerine capsule version)
- Anyone who wants a one-pill-per-day convenience
- People who need visible third-party certification on the label
How It Compares to Alternatives
vs. Doctor’s Best High Absorption Magnesium: Doctor’s Best uses the more advanced TRAACS chelation from Albion and is similarly priced. If absorption is your top priority, Doctor’s Best has a slight edge. If price is king, NOW Foods tablets win — especially the 240-count bottle.
vs. Nutricost Magnesium Glycinate: Nutricost is another budget option with similar pricing. NOW Foods has the advantage of 50+ years of brand history and in-house ISO-accredited labs. Both are solid budget choices.
vs. Pure Encapsulations Magnesium Glycinate: Pure Encapsulations is the premium, hypoallergenic option at about 3x the price. Worth it for people with sensitivities, but overkill for most buyers. NOW Foods delivers comparable magnesium quality at a fraction of the cost.
vs. Solaray Magnesium Glycinate with BioPerine: Solaray offers 350mg per serving with BioPerine. It’s more per serving but also more expensive per bottle. A solid mid-range option if you want more magnesium per capsule.
The Bottom Line
NOW Foods Magnesium Glycinate is the best budget magnesium supplement on the market. It uses quality Albion chelated magnesium, comes from a brand with over 50 years of trust, and costs less per day than almost any competitor.
The trade-offs are the large tablet size and needing multiple tablets per day. If those don’t bother you, this is an outstanding value.
Our rating: 4.4/5
It loses points for the large tablets and lack of visible third-party certification. But for the price, the quality-to-value ratio is hard to beat.
