Spring allergies get all the attention in late March, but there’s a quieter health thing happening right now that nobody talks about. Your vitamin D levels are probably at their lowest point of the entire year. After months of shorter days and spending most of your time indoors, the deficit is real. I always restock D3 in late March because it takes weeks to build levels back up, and waiting until summer means you’re behind the whole time.

This week’s Berry Basket is heavy on Nature Made, and for good reason. Their vitamin lineup is running some of the best discounts I’ve seen outside of Prime Day. The D3 5000 IU softgels landed at 56% off with a bestseller rank of #3, which tells you this isn’t some clearance situation. Garden of Life also showed up with a couple of solid picks, including their Zinc supplement that’s sitting at the #2 bestseller spot. When two trusted, USP-verified brands run discounts at the same time, that’s when you pay attention.

Twelve picks today, mostly focused on the vitamin D3 options that prompted the whole post, but I also pulled in B vitamins, magnesium, collagen, and a couple of immune support finds that were too well-priced to leave out. If you’ve been meaning to restock your supplement shelf after winter, this is the week.

What are the best Nature Made vitamin D3 deals right now?

Nature Made is running three separate D3 formulas at 52-56% off this week. The 5000 IU softgels are the standout for adults who know they’re deficient, while the 2000 IU tablets work better for daily maintenance. All three are sold by Amazon directly and ship with Prime.

Nature Made D3 5000 IU Softgels

This is the one to grab if you’re serious about getting your D3 levels back up. The 5000 IU dose is what most doctors recommend for people who test low, and the softgel form absorbs better than tablets because D3 is fat-soluble. A 180-day supply means you’re covered through the entire summer and into fall. The #3 bestseller rank across all vitamin D supplements says a lot about how many people trust this specific product.

  • 5000 IU (125 mcg) per softgel
  • 180-count, 180-day supply
  • Extra strength for bone and immune health

Nature Made D3 2000 IU Tablets

If 5000 IU feels like too much, the 2000 IU tablets are a better fit for maintenance dosing. You get 400 tablets in this bottle, which is over a year’s supply at one per day. This one is tagged as a Big Spring Deal, so the price may not hold past the event window. For the cost per tablet, this is hard to beat from any brand, let alone one with USP verification.

  • 2000 IU (50 mcg) per tablet
  • 400-count, 400-day supply
  • Big Spring Deal pricing

Nature Made D3 5000 IU Gummies

Same 5000 IU potency as the softgels above, but in gummy form for people who don’t like swallowing capsules. The 75-day supply is shorter than the softgel version, which is the tradeoff you make for the gummy format. Ranked #14 on the bestseller list, so it moves well. If you’ve tried and failed to stay consistent with tablet-form vitamins, gummies solve that problem for most people.

  • 5000 IU per serving in gummy form
  • 150 gummies, 75-day supply
  • Extra strength for adults

Which B vitamin supplements are worth buying this week?

B12 and B-complex supplements are deeply discounted from both Nature Made and Garden of Life this week. The Nature Made Super B Complex sits at the #1 bestseller rank in its category, and Garden of Life’s liquid B12 offers an alternative for people who prefer drops over pills.

Nature Made B12 5000 mcg

The maximum strength 5000 mcg B12 softgels from Nature Made are designed for people with diagnosed deficiencies or those on restricted diets that limit B12 intake. At the #5 bestseller rank, this is one of the most popular B12 supplements you can buy. The softgel form means faster absorption compared to standard tablets. A 60-day supply keeps things simple with one per day.

  • Maximum strength 5000 mcg B12
  • 60 softgels, 60-day supply
  • Energy metabolism support

Garden of Life B12 Liquid

Garden of Life takes a different approach with a liquid B12 in raspberry flavor. It’s USDA organic and uses methylcobalamin, which is the active form your body can use immediately without converting it first. The 2 oz bottle is compact enough to travel with, and the liquid format works well for anyone who has trouble with pills. This is part of the Big Spring Sale, so the discount has a timer on it.

  • USDA organic liquid B12
  • Raspberry flavor, 2 oz bottle
  • Methylcobalamin form

Nature Made Super B Complex

The #1 bestselling B-complex supplement, and it’s not hard to see why. This combines the full B vitamin range with vitamin C and folic acid in a single tablet. A 140-day supply at this price point makes it one of the most cost-effective ways to cover your B vitamins. If you’d rather take one product instead of separate B12, B6, and folate bottles, this simplifies things.

  • Full B-complex with vitamin C and folic acid
  • 140 tablets, 140-day supply
  • #1 bestseller in category

Collagen and immune support supplements on sale

Nature Made’s collagen gummies and zero-sugar vitamin C are both running at close to half off, and Garden of Life’s Zinc supplement is at the #2 bestseller rank with a Big Spring Deal discount. These are solid restocking prices for supplements most households go through regularly.

Nature Made Collagen Gummies

Nature Made Collagen Gummies combine hydrolyzed collagen peptides with vitamin C, zinc, and biotin in a single gummy. That combination matters because vitamin C is required for your body to synthesize collagen properly. The 60-day supply keeps you consistent for two months. Ranked #11 on the bestseller list, which puts it in the top tier for collagen supplements in gummy form.

  • Hydrolyzed collagen peptides with vitamin C, zinc, biotin
  • 60 gummies, 60-day supply
  • Supports healthy skin

Nature Made Zero Sugar Vitamin C

Zero sugar vitamin C gummies are a newer addition to Nature Made’s lineup, and they’ve climbed to the #52 bestseller rank quickly. Each serving delivers 250 mg of vitamin C without aspartame or added sugar, which is a combination that’s harder to find than you’d expect. The 50-day supply is reasonable, and the gummy format makes them easy to take daily without water.

  • 250 mg vitamin C per serving, zero sugar
  • 100 gummies, 50-day supply
  • Aspartame free

Garden of Life Zinc

Garden of Life’s Vitamin Code Zinc is sitting at the #2 bestseller rank, and it’s tagged as a Big Spring Deal. The formula includes 30 mg of zinc alongside vitamin C, trace minerals, and probiotics, which is a more complete approach than most standalone zinc supplements. The 60 vegan capsules are made from whole food sources. If you take zinc regularly for immune support, this is a strong price on one of the most popular options available.

  • 30 mg zinc with vitamin C and probiotics
  • 60 vegan capsules from whole food sources
  • Big Spring Deal pricing

Are these magnesium and kids vitamin deals any good?

Two magnesium formulas from Nature Made are discounted right now, including the L-Threonate version that’s been gaining popularity for cognitive support. There’s also a solid kids multivitamin pick if you’re restocking for the family.

Nature Made Magnesium L-Threonate

Magnesium L-Threonate is the form that crosses the blood-brain barrier, which is why it’s become popular for cognitive support and sleep. Nature Made’s version adds vitamin C and D3 to the formula. This is a Big Spring Deal with roughly 41 hours left on the timer, so the window is tight. At 51% off, it’s one of the better prices I’ve tracked on a magnesium L-threonate product from a major brand.

  • 1800 mg magnesium L-threonate providing 130 mg magnesium
  • Includes vitamin C and D3
  • 90 capsules, 30-day supply

Nature Made Magnesium Complex

This magnesium complex blends four forms: glycinate, malate, citrate, and oxide, plus vitamin D and zinc. The multi-form approach means different absorption rates and benefits from each type. The 30-day supply is shorter than I’d like, but the formula breadth is genuinely useful if you’re not sure which magnesium form works best for you. Ranked #60 on the bestseller list and tagged as a Big Spring Deal.

  • Four magnesium forms: glycinate, malate, citrate, oxide
  • Includes vitamin D and zinc
  • 60 capsules, 30-day supply

Nature Made Kids First Multivitamin

Nature Made Kids First is a gummy multivitamin with omega-3s, which is a combination that covers two common gaps in kids’ diets at once. The 70-count bottle lasts a little over two months at one gummy per day. Ranked #101 on the bestseller list, it’s a well-established product rather than something new and untested. If you’re already stocking up on your own supplements, adding this for the kids makes the order worthwhile.

  • Kids gummy multivitamin with omega-3
  • 70 gummies per bottle
  • Vitamins and minerals for nutritional support

Frequently asked questions

Is Nature Made vitamin D3 a good brand?

Nature Made is one of the few supplement brands that carries USP (United States Pharmacopeia) verification, which means an independent lab has tested the product for purity, potency, and ingredient accuracy. Their D3 supplements consistently rank in the top 25 bestsellers. The brand has been around for decades and is sold directly by major retailers, not just third-party marketplace sellers.

Should I take 2000 IU or 5000 IU of vitamin D3?

The 2000 IU dose is generally considered a maintenance level for adults who aren’t deficient. If you’ve been tested and your levels are low, most healthcare providers recommend 5000 IU daily until levels normalize. It’s worth getting a blood test before choosing a dose, since too much D3 over long periods can cause issues.

Are vitamin D3 softgels better than gummies?

Softgels generally offer better absorption because vitamin D3 is fat-soluble and the oil-based softgel delivers it in a form your body can use efficiently. Gummies are easier to take and taste better, which helps with consistency. If absorption is your priority, go with softgels. If you struggle to take pills daily, gummies are the better choice because the supplement you take is always better than the one you skip.

How long do these supplement deals last?

Several of these deals are tagged as Big Spring Deals with limited-time windows, some ending within 41 hours of this post going live. Standard discounts from Nature Made and Garden of Life tend to fluctuate weekly. If you see a price you like, it’s generally better to grab it rather than wait, especially on bestseller-ranked products that move fast.

Can I combine multiple supplements from this list?

Yes, but watch for overlap. The magnesium L-threonate already includes vitamin C and D3, and the collagen gummies include zinc and vitamin C. Stacking too many products with the same vitamins can push you past recommended daily amounts. A good starting point is one D3 product, one B vitamin product, and then any specialty supplement like magnesium or collagen based on your needs.

Prices verified March 30, 2026.

This week’s health deals ranged from 39% to 56% off, with the deepest discounts concentrated on Nature Made’s vitamin D3 line. That’s notable because Nature Made rarely runs D3 below 40% off outside of major sale events. The Big Spring Sale is doing a lot of heavy lifting here, and several of these deals have countdown timers that suggest they won’t last into next week. If you want to browse all deals across other categories, the full list is always updated.

The standout deal for me is the Nature Made D3 5000 IU softgels at 56% off. A 180-day supply of a #3 bestseller from a USP-verified brand at that discount is the kind of deal I’d grab without hesitation. The Garden of Life Zinc is a close second because of the #2 bestseller rank and the Big Spring Deal pricing. If I had to skip something, the magnesium complex is fine but the 30-day supply feels short for the price, even at 40% off.

Nature Made’s D3 line tends to spike in price once spring sale events end and summer demand picks up, so if you’ve been thinking about restocking, the next few days are probably the window. I’d also keep an eye on Garden of Life. They showed up with multiple Big Spring Deals this week, and brands that participate heavily in these events sometimes extend discounts or run follow-up promotions in April.
